is lcd display good for eyes manufacturer

The television is one of the most common electronic in any household. Even in the age of digital media, people choose to spend their free time at home with their families watching television.

Some people are hooked to watching show after show, putting their eyes at risk. But screen type is not the only factor in eye-healthy screen time. It really depends on the TV brightness, room lighting, distance from the screen, and view time. How? Let’s break it down:

Whatever type of television you have, it emits light with most TVs emitting at least 50% of blue light. Because blue light is closer to UV rays on the light spectrum, it may have similar qualities to how it affects people. Blue light exposure has long been linked to health issues such as eye damage, vision loss, and insomnia. So, as the brightness of your TV is increases, the color, and contrast of the image decrease, causing eye strain.

Ambient lighting should be present in the room when watching TV. It’s not a good idea to watch TV in complete darkness -- yes we’re talking to you late-night viewers. The room’s brightness should be adequate and comparable to the television. Even in theaters, the lights are never completely off, just dimmed; that same rule should apply to your home.

The closer you go to the television, the more your eyes begin to strain. For both kids and adults, it is not necessary nor healthy to sit close to the screen. The basic rule is to sit at least five times as far away from the screen as it is wide. So, if your television is 32 inches wide, for example, the ideal viewing distance is 160 inches or around 13 feet.

The recommended viewing distance for televisions with 4K resolution is one and a half times the screen size. The recommended distance for HDTVs is three times the screen size of the TV. These guidelines also go for children, who may be the biggest culprits in non-safe viewing practices. If you must, rearrange your living room to space out the good seats away from the TV.

How does that translate into TV screen types? And what screen type should people use to better protect their eyes when watching various shows on television?

The most common display technologies are LED and LCD. The latest TV display technology is OLED, which is only available on high-end TVs. The pixels used to provide the display are the difference between LCD, LED, and OLED. When compared to LED backlight, OLED has a far higher resolution and delivers cleaner, better graphics.

An OLED (Organic Light-Emitting Diodes) screen consists of numerous pixels that emit its own light. Each pixel is made up of three separate RBG – red, blue, and green – OLEDs. OLEDs are true emissive components that produce light on their own and do not require a light source. Meaning they produce a light that’s more natural and less harsh on your eyes.

OLED TVs also provide excellent color and contrast because they do not use light from other sources to display colors, as LCD/LED TVs do. They also, on average, produce around 20% less blue light than LCD displays.

Both LCD and LED TVs work in similar ways to each other. The only difference between the two is the type of backlighting. A TV labeled as an LED utilizes LED illumination for the white backlighting instead of fluorescent (CFL) lamps.

While LED LCD TVs are more appealing than CFL LCDs, they cannot compete with OLED panels since the LCD/LED front panel is a liquid color display that is not self-emissive. Which is the biggest disadvantage of LCD/LEDs in terms of eyesight. Although they produce quality images, the color and contrast from these displays are due to their light sources, so they give off more brightness that can cause eye strain if not moderated.

To sum it up, OLED displays are better for your eyesight. They have more natural lighting, better color contrast, and a wider color range. However, no matter what type of display you have, you will hurt your eyesight if you don’t practice safe TV viewing.

Is LCD or AMOLED better for eyes？The full English name of LCD is Liquid Crystal Display, which is a general term. According to its driving method, it can be divided into various specifications. Most monitors and laptops on the market today are thin-film transistors. Because TFT has better color saturation and viewing angles than other technologies, it is also the mainstream specification on the market today. The models on the market are mainly based on TFT, and LCD has now become synonymous with the term TFT display. Next, I will tell you in detail which LCD screen or OLED screen is better for the eyes.

Both OLED and LCD can cause damage to the eyes, because both OLED and LCD emit blue light, which is unavoidable. However, users can turn on the eye protection mode of the mobile phone to reduce the damage of blue light to the eyes. In addition, OLED"s dimming technology and LCD"s blue backlight are also one of the reasons for the "eye-hurt". OLED adopts PWM low-frequency dimming technology, which is a technology that adjusts the brightness through the rapid flickering of the light-emitting unit, so looking at the screen for a long time will cause eye fatigue. The blue backlight of an LCD monitor emits high-energy short-wave blue light.

In terms of manufacturing process, OLED adopts self-luminous technology and has no backlight layer, so this screen can be made very thin. In addition, each light-emitting unit of OLED can emit light independently when it emits light, and has the function of color screen display. LCD is composed of backlight layer, liquid crystal layer, color filter and other components, and the screen is made of inorganic materials, so the service life of this screen is relatively long.

Is LCD or AMOLED better for eyes？The above is the difference between lcd and oled. Users should try to avoid staring at the phone screen for a long time. Reduce LCD and AMOLED viewing time in dark environments. If you have the habit of reading late at night, you also need to turn on a light to neutralize the strobe light. Moisten your eyes with eye drops when your eyes are dry.

If you are shopping for a new display, you may be comparing LCD vs LED monitors for eye strain. Or, you may be searching for the leading monitor for the eyes. Even the best computer monitors, after all, can cause eye fatigue with prolonged use. So which monitor type is better to avoid eye strain? Keep reading to find out.

Unfortunately, there is no easy way to declare either display type as the victor when it comes to reducing eye fatigue and eye strain, and this does include some of the top-rated curved monitors, too. This is due to the fact that eye strain and fatigue have different causes for different people. Each monitor type, however, does excel with certain scenarios, such as when you are comparing LCD vs CRT computer monitors. If you’d like to understand what is a CRT TV, our guide can help you.

Even some of the finest touch screen monitors sometimes can cause eye problems after extended use. Keep reading to learn more about monitor types, visible light, and vision syndrome.

Digital eye strain can be caused by repeated exposure to blurry images. If you are susceptible to the kind of eye fatigue brought on by blurriness and are comparing LCD versus LED monitors, go for an LCD screen with a refresh rate of 120Hz or above. This blazing-fast refresh rate will minimize blurring and, as such, any eye fatigue that accompanies it. Be sure to check which kinds of ports are available before making a monitor purchase, such as comparing monitors with DisplayPort vs HDMI, as some older connection types may not excel with high refresh rates.

LCD monitors tend to offer a wider variety of viewing angles, which can help eliminate the kind of eye fatigue related to geographical discomfort. Any monitor type can offer a perfect viewing angle, so long as it is placed correctly and you are sitting at the right distance. Even if you’re using a monitor in conjunction with another device, like the best monitor for Macbook Pro, you can get a good viewing angle from it. Still, in a pinch, LCD panels are the way to go. If you are especially concerned with viewing angles and the field of view, go with an ultrawide monitor with a 21:9 aspect ratio.

Anyone can experience eye fatigue or eye strain when they are working long hours in front of a computer. Dimming the monitor’s light can help reduce eye strain from the monitor but at the expense of being able to see what is going on. Generally speaking, LED monitors offer more robust dimming options and various brightness settings without sacrificing visual quality. Experts suggest that eye strain can occur in as little as three hours, so if you work a full eight-hour day, this is something to consider.

Indeed it does. Short-wavelength blue light is one of the primary causes of eye fatigue. Be wary when using digital devices to reduce digital eye strain and keep an eye on the brightness settings.

Too much exposure to blue light can cause various issues with vision, so be wary while using digital devices for long periods of time to avoid any associated vision syndrome.

47% of U.S. consumers admitted to being unable to last a day without their mobile devices in a 2014 study done by the Bank of America, demonstrating the increasing prevalence of mobile devices. Mobile devices use LCD screens which emit blue light and thus negatively affects not only vision but also overall health. Continual extended screen time mainly can impact your eyes in two major ways.

Digital Eye StrainWhen we look at a screen, our blink rate drops significantly, thus causing digital eye strain. Signs of digital eye strain include slightly blurry vision after using LCD screens for prolonged periods, headaches, dry or tired eyes.

Though digital eye strain is temporary, if left unaddressed, it can turn into a chronic problem.The easiest way to address digital eye strain is to blink more as blinking helps to keep eyes lubricated. Alternatively, try using the “20-20-20 Rule”. Every 20 minutes, stare at something at least 20 feet away for at least 20 seconds. This exercise engages your distance vision and allows the eyes to rest.

Blue Light ExposureBlue light is the highest energy wavelength of visible light. This energy is able to penetrate all the way to the back of the eye, through the eyes’ natural filters. The rapidly increasing amount of blue light exposure that we get each day through digital device use is causing permanent damage to our eyes. The effects of blue light are cumulative and can lead to eye diseases like macular degeneration.

Children are especially at risk due to their developing eyes. Protective pigments which help filter out some of this harmful blue light are not yet present. The risk is worsened further due to their increased exposure to LCD screens.

Studies have also shown that exposure to blue light before bedtime actually suppresses melatonin secretion and delays deep REM sleep significantly. Your health is thus adversely affected. This may lead to reduced cognitive abilities and the development of chronic illnesses in the long run.

Try minimising usage of LCD screens by reading print media or using E Ink displays instead. The InkCase, for example, allows users to read for prolonged periods with minimal power consumption by adding a secondary E Ink screen on the back of your phone.

As we all know, AMOLED screen is a screen made of self-luminous organic materials. It does not require LCD backlight. When current passes through organic materials, pixels will emit light by themselves. Therefore, compared to LCD screens, AMOLED has more Pure black, higher contrast and other display advantages.

However, being more "ideal" also means paying more. The "eye-damaging" of AMOLED displays stems from external dissatisfaction with the current widespread adoption of PWM low-frequency dimming by AMOLED manufacturers. Here is a brief explanation of the PWM low frequency dimming technology.

All displays have a brightness adjustment function, but due to the differences in materials, the dimming technology is different. The current mainstream brightness adjustment technologies for smart phones are DC dimming and PWM dimming.

LCD screens rely on LED backlight panels to emit light. Therefore, in the field of smart phones, LCD screens mostly use DC dimming. This is a technology that directly adjusts the brightness of the two sides of the light-emitting component to adjust the brightness. The smaller the current, the lower the brightness.

DC dimming is relatively straightforward, but it also has a big disadvantage. Due to the different wavelengths of the three primary colors, DC dimming can cause unavoidable color casts under extremely low brightness conditions, such as early LCD displays with DC dimming , At low brightness, there will be obvious problems of discoloration.

The DC dimming does not seem to be suitable for AMOLED screens. AMOLED screen is a technology that relies on organic materials to emit light. The display quality is greatly related to the material, and the color difference between pixels will be very obvious.

In fact, even though this problem has not been solved very well, maybe it is the case that PWM dimming has become another option and has entered everyone"s sight.

Unlike DC dimming, which directly adjusts the current to control brightness, PWM dimming is more clever. Everyone knows that switching the light source will cause flicker. The faster the switching speed, the faster the flicker. When the frequency of switching the light source exceeds the limit of the human eye, the brightness of all pictures is superimposed in the human eye, so the frequency will affect the brightness of the screen. This technique is called PWM dimming (pulse width modulation).

The introduction of PWM dimming solves the problem of low-brightness color cast in the early days of AMOLED displays, and in fact further improves color stability.

However, with PWM dimming, even if the human eye cannot sense the picture change during the switching process, we will respond to this phenomenon. It is more likely to cause fatigue on the muscles on both sides of the eyes, thereby stimulating the refraction system to accelerate vision Ageing.

At present, Samsung ’s AMOLED screens use 250Hz low-frequency PWM dimming technology. When the screen brightness is lower, the possibility that the human eye can perceive becomes larger, and it is more likely to affect sensitive people.

AMOLED displays that use PWM low-frequency dimming for a long time do seem to affect vision, but do n’t think that LCD can survive. Even with DC dimming, it also has an irreversible effect on vision-cannot be ignored Blu-ray hazard.

Different from the AMOLED self-emission mode, the LCD screen uses a combination of backlight and filter imaging. In mainstream technology, many LCD screens will use blue LED backlight panels, which are covered with red, green and colorless three. This kind of filter forms three primary colors of RGB when blue light passes through these three filters.

Among them, the short-wave blue light emitted by the blue backlight board can cause harm to human eyes. Because short-wave light has a greater capacity density and is more penetrating, it will directly penetrate the lens to the retina, causing atrophy or death of retinal pigment epithelium cells.

From a technical point of view, whether it is an LCD or an AMOLED screen, the impact on vision is universal. As far as smartphones are concerned, it cannot be said that AMOLED screens are more eye-damaging than LCD screens.

Even if the LCD party held high the banner that PWM low-frequency dimming is harmful, it could not fully prove that AMOLED screens have an impact on vision, because everyone"s habits of using mobile phones are different, and the impact on everyone is different. There is no doubt that in the end, it is still the habits that need attention. For example, users should try to avoid watching the phone screen for a long time; reduce the viewing time of LCD and AMOLED low brightness in the dark environment.

“I’ve changed to a high-end smartphone with an OLED screen, but my eyes feel uncomfortable.” More and more netizens have this problem. Do OLED screens really hurt our eyes? Recently, a reporter investigated this phenomenon.

“I would never have thought that my eyes were becoming uncomfortable after using a new mobile phone for a few days.” Recently, a netizen reported this issue.

She went to see a doctor and was diagnosed with floaters. The doctor advised her to use her mobile phone less. It is strange that her symptoms were relieved after she changed back to her old mobile phone.

According to the reporter’s investigation, quite a few users have such questions. There are nearly 400,000 related links in Google search for “Eyes hurt by OLED screens“. Many related posts have resonated with netizens because they also had this symptom.

The problem is, do OLED screens really hurt our eyes? The reason why you feel uncomfortable when using mobile phones with OLED screens is that they flicker.

LCD screen usually uses LCD backlight to realize screen luminescence, the flickering frequency of which can reach several kilohertz (Hz) that flickering will basically not occur. The pixels for OLED screens are self-luminous, the low power of which has limited its flickering frequency. At present, the flickering frequency of the PWM dimming of OLED screens on many mobile phones is about 215Hz-250Hz.

IEEE (Institute of Electrical and Electronics Engineers) once reported that the range of flickering frequency with low health risks is above 1250Hz. “Flickering may lead to migraine and other diseases.”

In the eyes of communication industry professionals, this value is not high. But even the medical circle has not given a clear answer to this question, which is a great controversy in the industry.

Jie Chuanhong is the director of the ophthalmology department of the Eye Hospital of China Academy of Chinese Medical Sciences. He said in an interview that whether you watch the mobile phone screen, computer screen, or iPad screen for a long time, it is easy to cause visual fatigue, which should not be directly related to the screen.

“There is no direct relationship between OLED screen and eye harm.” Communication industry professionals also said that human eyes are almost imperceptible to the flickering of OLED screens. “Visual fatigue may be caused by staring at the screen for too long.”

Some experts claim that both LCD and OLED screens can harm human eyes because they will emit blue light harmful to the eyes, which is inevitable. However, OLED has a way to avoid this problem, enabling the eye-protection mode (similar to PWM dimming) and changing the color tone of the screen to yellowish.

Many netizens also suggested that when using smartphones with OLED screens, we should increase the brightness as much as possible because the lower the brightness, the more harmful it will be to our eyes. When the brightness of the screen is reduced, the screen of the smartphone will further reduce the flickering frequency.

Some ophthalmologists suggest that “human eyes have different perceptions of OLED flickering, and some people are more sensitive. Sensitive users had better use smartphones with LCD screens.” There has not been a unified medical statement about this conclusion.

Some netizens even made a comparison experiment: you can obviously feel that the screen of P30 Pro is not as good as that of Mate20 Pro. This is easy to understand. Different mobile phones may use different screens, and manufacturers such as Samsung, LG, and BOE have different technologies and product quality.

Some experimental results have shown that screen size is not the main factor influencing visual fatigue but the material and physical properties of different electronic screens.

Even for the same mobile phone, whether the screen is good or not depends on “luck”. Because different brands of OLED screens may be used in the same mobile phone model, in many cases, the mobile phone manufacturer will not specify this, nor does it list the screen provider in detail in the user manual.

For example, Mate20 pro screen suppliers include BOE and LG, and some of their products have experienced “green screen” events after being released on the market. According to media reports, all the mobile phones with green screen problems are those with LG screens. That is to say, the screens in the same mobile phone model may be different for the same price. Whether the mobile phone is good or not depends on luck.

This is almost a common problem in the industry. Initially, both the iPhone XS and XS MAX were equipped with Samsung’s OLED screens. But then Apple listed LG as its second iPhone XS screen supplier. In other words, LG screens may be used in the subsequent batches of iPhone XS and XS MAX. Whether consumers buy LG screens or Samsung screens depends on luck.

The color of OELD screens is more vivid, fuller, and realistic. High-end smartphones have been equipped with OLED screens, which have become the mainstream; LCD screens have been used for low-end smartphones, which are no longer the preferred choice.

Why did this happen? “Terminal products such as the ones with fingerprints under the screen and ultra-thin products can only be realized by using OLED screens.” It has become a common recognition in the industry.

Now there is good news BOE suddenly announced that it has successfully developed fingerprint technology under LCD screen, which will be mass-produced by the end of this year.

It is unrealistic for the mobile phone industry to return to LCD screens from OLED screens, and even some people think it means the degeneration of technology. From the perspective of eye health alone, LCD screens will also emit blue light harmful to human eyes. If we really want to protect our eyes, we must reduce the time consumed by smartphones.

AMOLED displays are designed for consumers not only because of their breathtaking appearance, but also because of they are one of the safest display technologies ever developed.

Experts tell us that the human eye typically will perceive about 80% of the information that reaches our visual sensory system. This means that digital displays are very significant, both in the long run and in our day-to-day activities.

As important as a digital display is in daily communications, we should also be aware that digital displays emit ‘blue light’ that has the potential to harm our eyes.

Based on research by the Mobile Market Research Institute, the average amount of time that people in their 20s use their smartphone is about four hours a day.

Moreover, that time frame has been continually increasing. Of course, the longer we use our smartphones, the more our eyes are exposed to the potentially damaging effects of ‘blue light’.

Their experiments on rats, which centered on flashing rays of various colors on their eyes, showed that the 80% of their retinal cells were subject to damage by blue light.

Some smartphones even have a control with which to reduce the amount of blue light that they are releasing But first let’s be clear that blue light is not the same as blue-ray.

Blue-ray light has a wavelength between 380~500 nanometers (nm), which is within the range of light that human eyes can visibly detect. But, the fact that the color is blue doesn’t necessarily mean that the light is harmful.

Based on results of experiments presented for a thesis published by UPMC (University in France), the wavelength that can harm human retinal cells is only between 415~455nms, and this light can actually impact our vision sooner than we realize.

With this concern in mind, we must ask if there is any way that the potentially detrimental blue light can be reduced in the electronic devices that we use.

As a result of the company’s constant efforts to improve AMOLED technology, the potentially problematic blue light coming out of a Samsung AMOLED display is now half as much as that from most conventional LCD displays.

Samsung Display’s AMOLED can block potentially harmful blue light by reducing the illumination of wavelengths between 415 to 455nm while increasing the illumination of safer wavelengths nearby.

Due to the outstanding capability of Samsung AMOLED displays to protect our eyes, in 2016, Samsung received a certification of ‘Safety for Eyes’ from VDE, a widely recognized international certification authority in Germany, after passing VDE’s blue light testing.

Samsung AMOLED displays present a wide range of advantages with the special self-illuminating feature that do not appear in LCD displays now on the market.

AMOLED, from Samsung Display, is evolving to become a series of digital products that are not only technologically superior but also comforting to our eyes, while continuing to deliver sharper images.

There is a constant debate on Amoled vs LCD, which is a better display? Where Amoled display offers some remarkable colors with deep black eye-soothing contrast ratio, LCD displays offer much more subtle colors with better off-axis angles for viewing & offers a much brighter picture quality.

While purchasing a new smartphone we consider various specifications like software, camera, processor, battery, display type etc. Among all the specifications display is something that most people are concerned about. 2 of the major competitors of smartphone display are AMOLED and LCD. Often in the LCD vs Amoled comparison, people get confused about which one to choose. In this article, we have explained a clear comparison of the Amoled vs LCD screen to find out which is actually better.

Amoled display is nothing but a part of OLED display which comes with some extra features. The first component is Light Emitting Diode (LED) and the second component is "O", here "O" stands for organic & together they make OLED. The real meaning derived from it is organic material placed with 2 conductors in every LED. And this is how light is produced.

The OLED display can generate light out of individual pixels. AMOLED displays contain Thin Film Translator (TLT) which makes the overall procedure of sourcing current to the correct pixel much quicker and smoother. The TXT further helps grab control for operating different pixels at a time. For example, some pixels could be absolutely switched off though others remain on in Amoled displays. This produces a deep black color.

Speaking about LCDs, it is relatively pretty much commonly found in today"s smartphones. LCD (Liquid Crystal Display) offers a devoted black light that is white or rather slightly blueish in color. Mostly here we get a blue light that is passed through some yellowish phosphor filter which brings out the white light. The white light is subsequently passed through multiple filters and thereafter the crystal elements are again passed through blue, red & green filters. Note that LCD displays have both passive and active matrix which depends on the cost and requirement involved.

Since the process involved in LCDs is much more complex than Amoled & requires extra steps, when compared to AMOLED displays, LCDs are less battery friendly. In the technological era where energy efficiency is the first priority, Amoled displays are certainly going to be the future of display technology. But both of them come with a separate set of pros and cons and it is only by knowing the pros and cons you will be able to choose the right one.

Amoled display technology is mostly used in smartphones, media players & digital cameras. Amoled is mostly used in low power, cost-effective & large application sizes.

Cost is one of the major factors that act as a differentiator between the two display types. Amoled displays are comparatively more expensive than LCD displays because LCD displays are much cheaper to manufacture. So while buying a low-budget smartphone, the probability to get a Amoled display is pretty less.

The quality of a display is mainly measured according to the colors and sharpness it offers. Also while comparing two displays, only technology comparison won"t work because often displays behave inversely even if a manufacturer is using the very same technology. If you consider colors especially contrasting colors such as blue, red or green, Amoled will serve better throughout the day. This happens mainly because in the case of AMOLED displays, as mentioned above, every pixel present in it emit its own light whereas in LCD light comes out of the backlight. Therefore Amoled displays offer high-end saturation and vibrant colors compared to LCD displays.

As Amoled displays put out vibrant colors, you will find Amoled displays to be warmer in nature compared to LCD displays which has a more neutral whitish tint. In short, the pictures seen on Amoled displays are more eye-soothing compared to LCD displays where the pictures appear more natural.

In the Amoled vs LCD screen display comparison, another thing to consider is the brightness offered by both of them. Compared to LCD displays, Amoled displays have lesser brightness levels. This is mainly because of the backlight in LCD displays which emits a higher brightness level. Therefore if you are a person who spends most of the time outdoors and mostly uses your smartphone under the sun, then LCD is the right choice for you. Although certain leading brands are working on the brightness level in Amoled displays.

The display is one such thing that sucks your phone"s battery to a great extent. In Amoled displays, the pixels can get absolutely switched off thereby saving a lot of battery. Whereas LCD displays remain dependent on the back light, as a result even if your screen is completely black, the backlight remain switched on throughout. This is why even though Amoled displays are more expensive than LCD displays as they consume much less battery than LCD displays.

In the battle between LCD display vs Amoled display both come with separate pros and cons. Well if battery consumption and color contrast or saturation is a concern then the Amoled display is going to win over LCD display anyway. While purchasing a smartphone, customers today mainly focus on two features- lesser battery consumption and a high-quality display. Amoled display offers both the benefits- high-end vibrant display and less battery consumption. The only criteria where LCD displays win over Amoled is the brightness level. But with brands coming with the latest technologies, Amoled is certainly going to catch up with the brightness level with LCD displays. Also, the brightness difference in current Amoled display smartphones that are available in the market is hardly noticeable.

Both screens are made up of Pixels. A pixel is made up of 3 sections called sub-pixels. The three sections are red, green and blue (primary colors for display tech).

The light is generated from a “backlight”. A series of thin films, transparent mirrors and an array of white LED Lights that shine and distribute light across the back of the display.

On some lower quality LCD screens, you can see bright spots in the middle or on the perimeters of screens. This is caused by uneven light distribution. The downside to using backlights, is that black is never true black, because no matter what, light has to be coming through, so it will never have as dark of a screen as an AMOLED screen. Its comparable to being able to slow a car down to 2 mph versus coming to a complete stop.

Each pixel is its own light source, meaning that no backlight is necessary. This allows the screen assembly to be thinner, and have more consistent lighting across the whole display.

In addition, since each pixel is an OLED (Organic Light Emitting Diode) or individual light, showing black means it shuts off pixels it doesn’t need to generate color.

So on the Samsung Galaxy S lineup of phones, the notification lock screen, which is white text on a black background, uses barely any power, because 90% of the screen is actually powered off.

Chances are, you use computers in the workplace, and while they’re helpful in a multitude of ways, they can cause eye strain. That eye strain can lead to blurry vision and even headaches and neck pain.

According to recent studies, as many as 90% of people who spend extended time in front of digital screens experience some sort of eye strain or related eye issues. While giving up computers all together may not be an option, you can take steps to keep your eyes safe while on the job and at home. Our experts at McDonald Eye Care Associates discuss practical tips to protect your eyes from eye strain.

Scheduling a comprehensive eye exam is one of the key steps in preventing eye strain related to computer screens. Our team at McDonald Eye Associates offers comprehensive eye exams to detect any visual issues and can explain how to keep your eyes safe from eye strain while at work.

People have a habit of sitting close to their computer screen, but sitting too close to your screen contributes to eye strain. Adjusting your screen position is a simple and easy step you can take to protect your eyes. You should sit at least 20-30 inches away from your screen and position the top of your screen at eye level. This not only reduces the chances of eye strain; it prevents neck strain.

When it comes to screen time in the workplace, lighting is everything. Offices that have too much natural or artificial light increase glare on your screen, which spells trouble for your eyes. Try tackling the glare in your office to ease the strain on your eyes.

Anti-glare screen filters are a simple way to cut down on the amount of light that reflects off of your computer screen while you work. The result is a more pleasant viewing experience that won’t result in eye fatigue and strain.

Anti-glare glasses have a coating that reduces glare and reflections to protect your eyes. This is an excellent option if you use laptops, cell phones, and other devices along with standard desktop computers.

Rest breaks for your eyes are something your grandparents didn’t have to plan into their day. But today we spend more and more time at our computer screens and need to consider giving our eyes a rest throughout the day. It’s best to give your eyes a short break after every two hours of continuous screen time. This could mean taking a five-minute walk to the watercooler during your workday.

Electronic manufacturers are pushing the boundaries with vivid screens that display colors and images that appear vibrant and bright. While this may look stunning, your eyes weren’t meant to look at bright, vivid screens for hours at a time. Going into your computer’s settings and turning down the brightness and backlight can go a long way in preventing eye strain.

If you use a traditional desktop, consider upgrading your monitor. LCD monitors are more gentle on your eyes than older technologies. A high-resolution LCD monitor is able to display crisp, sharp images without problems with flicker, so your eyes are in less jeopardy when working at the computer.

Did you know that when you stare at a screen for long periods of time it causes you to blink less often? When you blink less, your eyes can become dry and irritated, increasing the risk of eye problems. When at the computer, make it a point to blink normally and fully. If you find that your eyes feel dry, use artificial years to keep them moist.

At McDonald Eye Care Associates, we are a full-service eye care practice. For more information or to schedule a routine exam, call our Lakeville, Minnesota, office.

If you spend any time working in an office (home or otherwise) you’re likely going to spend long periods of time staring at a screen, which can leave you feeling extra worn down at the end of a day. You can help to mitigate this by investing in a monitor that helps actively reduce the amount of strain your eyes have to endure. Increasingly, companies offer monitors designed to help you end your workday without feeling like a zombie. As with all monitors, trying to find a selection amongst the various offerings can be difficult, so we’re here to help you make the most informed selection. This list of the best monitors for eye strain reduction could improve how you feel in front of and away from your desk.

As monitor technology has progressed over the last decade or so, the screens have only gotten more impressive. That leads to a slew of options to consider. I’ve covered consumer technology products for more than three years, and the PopSci editors have decades of experience writing about displays and other gadgets.

In order to source our selections, we leveraged our monitor testing program, consulted opinions from pundits at various outlets and compiled consumer feedback across the web. We also drew heavily upon our own informed knowledge of monitors to compare hard specs. We selected monitors to fulfill a handful of critically important categories. While these monitors can get expensive, the options on this list top out around $800.

You won’t find a monitor with more eye health features than this one. At first glance, it’s a typical 27-inch 1440p screen with thin bezels and a 60Hz refresh rate. But, there’s a lot of eyeball-friendly tech hiding under the surface. As you’d expect from a monitor on this list, it offers both blue light reduction and a completely flicker-free display. Beyond that, BenQ has added some more advanced protections. An infrared sensor knows how long you’ve been staring at your screen and can suggest occasional breaks to let your peepers rest.

BenQ’s adaptive brightness technology senses the ambient light in your room and automatically adjusts the brightness in order to keep viewing and eye health in the optimal range. A screen that’s too bright in a dark room can be just as bad for your eyes as a screen that’s too dim in a bright room. They both cause strain.

This display even offers a simulated e-paper mode, which emphasizes contrast for text without cranking up the brightness on the white paper. It makes the screen easy to read, but it won’t bombard your eyeballs with unnecessary photons for the entirety of your reading session. If you’re truly worried about eye health, this is the monitor to get.

The sheer largeness of the Samsung Odyssey G7 Series 32-inch WQHD extends to just about everything in this monitor. The extensive curve on it makes it feel as if you’re surrounding yourself with whatever content is on screen. While the G7 doesn’t have any dedicated eye strain features, having a large and curved monitor such as this is a considerable upgrade over any sort of existing monitor you may have already. The G7’s curve is 1000R, which actively matches the curvature of the human eye, which not only helps to pull you further into the screen but helps to ensure minimal eye strain along the way. Samsung was one of the pioneers of screens with this much curvature.

Where the real value comes from is in just how many other features the monitor manages to pack into its frame. Gamers will likely love the G7, as its 240Hz refresh rate renders images with lightning-fast precision, while the 1ms response time ensures you don’t miss anything coming from the graphics card. With G-Sync and FreeSync, the images from your graphics card will perfectly match the monitor, providing a perfect mix between frames. The 32-inch display, bolstered by Samsung’s WQHD resolution, ties everything together in a beautiful package. So while you may miss dedicated eye strain features like flicker-free and blue light reduction, the Samsung Odyssey G7 Series 32-Inch WQHD ties everything together in a stunning package that’s nearly out of this world and is a monitor you can buy and be set for the future with.

As the name would suggest, the 27-inch Full HD ASUS Eye Care+ monitor packs in features specifically focused on reducing eye strain and improving your monitor viewing experience. An ergonomic design, anti-glare surface, and 75Hz refresh rate with AMD Sync technology ensure crisp, comfortable, flicker-free playback within the 178-degree viewing angle. Customizable Color Augmentation mode can help those with color-vision deficiency, while adjustable TÜV Rheinland-certified and Low Blue Light technologies make sure high-energy blue-violet emissions are kept in check and viewing is comfortable no matter your vision. And a Rest Reminder helps users manage screen time.

Why it made the cut:The LG 29WNG600-W’s ultrawide display comes with strong eye-strain reduction features, including a dedicated reader mode that will be handy for desk job workers.

The LG 29WN600-W 29-inch ultrawide monitor certainly lives up to its name, as it has handily earned a spot on this list for being the best ultrawide monitor. At 29 inches, there’s plenty of real estate for you to watch your favorite show, work on a variety of different documents, see all of your colleagues on a Zoom call, and more. The nearly borderless design allows you to take full advantage of that sizable 29-inch display, so there’s no wasted space like you may find on other monitors. The back of the monitor also includes pretty much every port you could want, including two HDMI ports, an audio jack, and one standard display port.

The other thing about the LG 29WN600-W 29-inch ultrawide monitor that we like is its dedicated reader mode, which provides “optimal conditions” for reading by not only reducing blue light but incorporating flicker-free technology as well. The flicker-free isn’t as strong as it is on other models, but you can easily switch over to reader mode whenever you’re settling in for a long day’s worth of work. Additional features worth mentioning are the ability to split your screen into different workspaces with the click of a mouse from the toolbar, AMD FreeSync to end any framerate choppiness, see rich black tones in your media content thanks to LG’s Black Stabilizers ability, and much more.

Why it made the cut:A high resolution with HDR and built-in eye care features make this gaming monitor as fun as dropping into your favorite battle royale game.

When it comes to gaming, most players will want to follow the Daft Punk philosophy: harder, better, faster, stronger. The ASUS Rog Strix XG27AQ 27-inch monitor fulfills every single one of those pillars, providing fantastic value for gamers who might also use that monitor for work as well. Diving into the gaming-oriented specs and you’ll see there’s pretty much everything they’d want here; the 27-inch screen size is just slightly larger than the monitor pro gamers use while the 1ms response rate yields crispy visuals at extensively high framerates. Additionally, G-Sync functionality makes it so you won’t see any screen tears from dropped frames. HDR allows for even richer and more vivid colors while providing richly textured blacks.

On the eye strain side of things, the Rog Strix is missing any sort of blue light filter (a filter would reduce the overall image color) but does include flicker-free technology and a wide viewing angle to better translate the full image. Additionally, that HDR can reduce how bright you need the monitor to be overall in order to get a punchy image. With plenty of ports, an eye strain feature that won’t alter your display, and plenty of other features to ensure you don’t miss a second of your favorite game, this is a monitor that’s worthy of your beefy gaming tower—and one primed to make Daft Punk proud.

Priced under $200, the ViewSonic VX2257-MHD 22-inch eye strain monitor is a little on the smaller side but it’s still a great option for work or as a secondary display. While the flicker-free and blue light filter technology is a critically important feature for an eye strain monitor, there are also plenty of other bonuses here which further serve its overall impressiveness. The 75Hz refresh rate represents a slight improvement over the typical 60Hz number. Plus, it offers AMD FreeSync to ensure the monitor isn’t dropping any frames, a feature you’ll find in many of the best gaming monitors. Additionally, the 170-degree viewing angle provides plenty of real estate for whatever activity you might be doing, whether it’s for work or for play.

As a budget pick, however, there are some drawbacks. The monitor is just a standard 1080p output, the build is a little on the chunkier side relative to most other monitors on this list. Additionally, there isn’t much in the way of ergonomics, which may require you to get creative with how and where you place the monitor in order to get the best eye line on it, as that will be important to also help in the reduction of overall eye strain. However, if you’re on a tight budget and just want to give your eyes some relief, the VX2257 is well, well worth it.

When looking to purchase the best monitor for eye strain reduction, you’ll want to keep a few different things in mind. If you’re having eye problems that include itching or blurring, headaches, discomfort, or just overall tiredness, you’re likely in the space to consider one of these monitors after talking to a healthcare professional. And while the harm-reduction features are important, you still want a well-performing screen. These variables and features are worth considering when you make your choice.

Eye strain reduction monitors are going to leverage a handful of different technologies in order to help your eyes feel less impacted. The key ones to look for include automatic brightness adjustment, blue light filters, and flicker-free abilities.

If you’ve used an Amazon Kindle or iPad before, you’re likely used to seeing automatic brightness adjustment work in real-time. Light sensors built into a device, in this case, your monitor, help to better regulate the brightness of your monitor screen by scaling up the brightness of the screen relative to the ambient light around you. So if it’s darker inside your room, the monitor will automatically brighten up, or if it’s too bright. It will tone it down if it’s dark in the room. Not only does it save you from having to make that adjustment on your own, but your eyes also won’t have to constantly strain to adjust to the lighting in a given space.

Blue light has gotten increased attention in the last half-decade or so as we’ve spent more and more time with technology in our lives. For those not familiar, however, a monitor can produce blue light, a short-wavelength but high-energy light that some people believe can make your eyes more prone to strain. Exposure to it at the wrong times can affect your sleep schedule. Blue light filters are now being built into a lot of monitors to actively block out that specific type of light and reduce the overall strain on your eyes.

Typical monitors adjust their brightness by flickering or cycling through its light sources. As this occurs, the screen actually flickers at a very rapid rate. This, in turn, causes your eyes to do the same, as your pupils move from large to small or vice versa. If this is happening multiple times throughout the day, imagine all the muscles that are working overtime to support that bodily function. By opting for flicker-free functionality, your monitor maintains a single, steady stream of light to avoid having to cycle through those brightness levels.

Ergonomic design allows you to move and adjust the monitor as you see fit, so it’s positioned at your eye level. After all, not having to strain your neck is important too. If you’re trying to really dial in your ergonomic setting, consider getting a monitor with VESA mounting capabilities and an adjustable monitor armso you can arrange your screen comfortable in front of you without the need to tilt your neck up or down.

When it comes to the actual display on the monitor, having a high-resolution panel (at least 1080p, if not 4K), along with strong RGB color accuracy settings, and a non-LED panel help to ensure your eyes are seeing everything clearly, without having to squint to do so. Sharper edges on text make it physically easier for your eyes to read, which can really add up over time.

You’ll also want to consider the display panel the monitor is using. We recommend looking for either IPS or VA panels. IPS (in-plane switching) panels focus on the liquid crystals inside the display. These crystals move and shift horizontally, which results in better viewing angles, more realistic colors, and improved overall quality. VA panels use those same liquid crystals but align them between panes of glass to create a darker display with higher contrast.

Curved monitors can also be helpful here. While expensive, a curved monitor helps to reduce the overall image distortion that can sometimes happen at the ends and edges of a flat-screen monitor. The curve can also help to improve depth perception by covering a larger area of your field of view. That translates to seeing images that are, overall, larger and therefore easier to see and look at for extended periods of time.

You’ll also want to consider how and when you’re using your monitor. If you’re primarily working a desk job in an office, your needs will be different than if you’re a Twitch streamer who is gaming all day long. For the majority of users looking to purchase an eye strain monitor, you’ll want to select a monitor with key features like flicker-free, a blue light filter, and a decent display resolution. For gamers, you may want to forgo the blue light filter so you can see the full richness of the game worlds you’re in and will also want to reach for a monitor that’s got a high refresh rate and a high (ideally) 4K resolution.

In this particular circumstance, there’s no limit to size. Most desktop monitors aren’t any bigger than about 24 to 30 inches (with the latter being on the upper side of that), so these displays all fall into that range. Just keep in mind you’ll need the desk space to warrant it, but these monitors come with stands, so you should be able to accommodate them accordingly. Plus, the bigger the monitor, the more likely it is to prevent you from squinting all the time.

A general rule of thumb for screen positioning suggests you should extend your arm and hand straight out from your shoulder and place the screen right at the end of your fingertips. This will reduce strain caused by focusing on objects that are too close to you without requiring you to squint or struggle to read small text on the display. Of course, everyone is different and you may find that a little closer or farther away more comfortable for your specific biology.

If you’re using a smaller screen with very high resolution, on-screen text can appear very small, which taxes your eyes when reading. If you’re using a smaller screen, you may want to enlarge the text on the display, which may require more scrolling, but less squinting.

The best monitors for eye strain reduction may require an investment up-front—depending upon what features you’re looking for—but the long-term benefits could be well worth it. With more and more of us working from home (and working longer hours) that extra bit of recovery makes all the difference. While no one product is ever a perfect fit, we’re confident our selections are about as perfect as you can ask for—but if something isn’t quite up to what you imagined, it’s better off to save for something that is. If you’re having eye issues, don’t assume these displays will fix it and absolutely consult a medical professional.

Have you ever had trouble falling asleep or gotten itchy eyes after a long day at the computer? As you probably know, all modern screens emit blue light, which can affect eye health and cause sleeping problems. But no need to panic! We have a few tips to help you protect your eyes and take better care of your vision.

Read on to learn more about blue light and how to protect your eyesight. Or discoverViewSonic’s broad range of monitorsdesigned with eye comfort in mind.

What is blue light? Have you noticed that your eyes get tired when you spend too much time in front of the computer? Sure you do, since you are the one who has to deal with the headaches, the super dry eyes, and even blurred vision at times.

What you may not be aware of though, is the impact it has on your vision, your sleep, and your health, as well as how you can immediately protect yourself by using a blue light filter.  You’ve seen that when people use their electronic devices in a dark environment, they are covered in a blue glow.

That’s high energy visual (HEV) light ready to disrupt everyone’s sleep.  While eye fatigue and sleep trouble may be the most commonly experienced problems, many other health issues are linking to blue light exposure. That’s why, below, we’ve endeavored to outline everything you need to know regarding blue light and blue light filters.

Somewhere between the two extremes exists the very tiny fraction human eyes can detect, which is known as the visible spectrum, with wavelengths in the range of 400 nm to 700 nm. What else is measured in nanometers? Transistors! Back in 1994 and 1995, the smallest transistors were 600 nm and 350 nm, respectively. Fast forward to 2018 when the Apple A12 Bionic chip was released containing 6.9 billion transistors manufactured using a 7 nm process.

Now, back to the visible spectrum and the colors of the rainbow: Red, Orange, Yellow, Green, Blue, and Violet. It’s crucial to notice blue light rays have the smallest wavelengths (380 nm to 500 nm) of all other colors in the visible spectrum because they have the highest energy photons.

Various technologies that light up the displays of the electronic devices use wavelengths in this range. However, the biggest source of blue light is the sun, which is known to be crucial in many ways. As such, it’s fair to ask, how bad can blue light truly be?

On an evolutionary scale, not long ago humans lived outdoors and were ruled by the sunrise and sunset. That’s why a blue-light-sensing protein called melanopsin exists in human eyes. The bright daylight activates melanopsin, thus synchronizing the internal clock to raise alertness, boost reaction times, and mood. However, melanopsin is less sensitive to lower energy light in the visual spectrum, which allows for the production of a sleep-inducing hormone called melatonin as the sun goes down.

The problem at hand is that 90% of our time is now spent indoors under artificial light, thereby resulting in a deficit of direct sunlight during the day and overexposure to bright light in the evening. This combination has resulted in consequences to the natural circadian rhythm – or the master clock – of the human body. Unsettling the circadian rhythm paves the way to many of the prevalent diseases experienced in the 21st century, such as depression, anxiety, and obesity.

Although inconclusive, scientific studies also suggest a connection between blue light exposure and macular degeneration, which the leading cause of vision loss in the US! As the years go by, the natural protective layer starts to become more and more permeable to UV and HEV rays that easily penetrate to the retina due to their shorter wavelengths.

In recent news, a Taiwanese woman developed a hole in her retina after years of using a smartphone outdoors and Dr. Hong, a doctor of Ophthalmology at Fooyin University in Kaohsiung, believes that the combination of the blue light emitted from the cellphone, and the ultraviolet light emitted by the sun led to this condition.

It seems as though blue light is both extremely beneficial and extremely dangerous. The best thing to do is to find ways to optimize the blue light intake during the day and regulate the exposure as the sun goes down. Thankfully, even NASA is invested in helping with this!

Most computer screens today use a type of panel with layers of liquid crystals between pairs of filters and electrodes. These are known as LCDs, short for “Liquid Crystal Displays.” LCD panels require an external source of light to produce visible images. As such, LEDs are now the industry favorite for the task, after dethroning CCFLs due to size, efficiency, and cost.

The array of LEDs is often placed behind the panel or around the edges of the screen providing a bright light source. The most common type is referred to as white-light LEDs, and they combine the emission from a blue LED (around 450nm to 470 nm) with a yellow phosphor. This combination looks white when viewed directly and it’s the reason why so much blue light is being emitted from computer screens and other electronic devices.

To make matters worse, white-light LEDs are known to suffer from degradation over time, thereby causing an increase of blue emission. This degradation happens primarily through the bleaching of phosphors so that they no longer efficiently absorb blue light, thus leading to further eye strain.

Nearly every ViewSonic model is equipped with a blue light filter capable of reducing up to 87% the emission in the blue spectrum while maintaining the correct color balance.

You are now fully aware of the different sources of blue light as well as the various health risks associated with it, so if you want or need some computer time after sunset hours, you would be wise to invest in a blue light filter for your PC.

For starters, and depending on your operating system, you may have the option to turn on Night Light (Windows 10) or Night Shift (macOS). Nevertheless, a study on the lack of effectiveness of Apple’s Night Shift regarding melatonin production may be a strong enough reason to consider other options.

Such options include computer screens with integrated blue light filters capable of reducing up to 87% of all blue light emissions and allowing for maximum user customization with different levels of protection and accurate RGB color balance.

This technology allows you to easily adjust the amount of blue light that is being emitted using a scale from 0 to 100 (where 0 represents the minimum level of blue light emission, meaning 87% of all blue light is being filtered out).

You can set the filter to different levels depending on the viewing scenario. Most users prefer to max out the filter (0-25) when reading or using text-based applications, making it easy on the eyes.

For web browsing or work-related tasks, you might want to allow in some more blue light by setting the filter to 25-50. These daily activities should remain comfortable with this level of blue light reduction.

When the main activity is related to high-definition multimedia, you can set the filter to 50-100. At 70 you receive better color balancing with sufficient blue light reduction without visible change in color.

As mentioned above, NASA developed special LED modules for the ISS (International Space Station) in order to help keep astronauts healthy during their stay in outer space. The former NASA scientists who came up with this ingenious solution are now devoted to bringing the same technology to the general public. These modules shift the peak output according to the time of the day and use an emission spectrum that closely imitates that of the sun during the day, while eliminating the short wavelengths from blue and green light when in pre-sleep mode.

Other valid alternatives, if your primary purpose is to reduce digital eye strain, include the use of third-party software such as f.lux or Iris, as well as blue light blocking eyewear. Please refer to a professional when choosing eyewear that filters or blocks blue light as these products may include magnification and specific optical centers.

Although proper eyewear seems to be most effective against the harmful effects of blue light, there are at least three aspects to consider. First of all, the price, which is heavily dependent on the quality of the lenses. Secondly,  the fit, which needs to be tight or else blue light still reaches the eye. Lastly, most blue light blocking glasses are difficult to use when overlaid against regular prescription glasses. All in all, PC monitors with built-in blue light filters present the most convenient solution when compared to these options.

Studies say blinking rates drop to one-third of normal when in front of a screen. For sure, that does not help with eye strain. With that in mind, consider the famous eye care rule called 20-20-20 according to which every 20 minutes you should focus for 20 seconds on any object 20 feet away from you. This simple exercise helps with headaches, blurred vision, double vision, and dry eyes.

Another perfectly valid way to give your eyes some well-deserved rest while staying productive during long hours in front of a computer display is using the Pomodoro Technique. This technique breaks down the day in 25-minute sprints with small breaks in-between. These breaks help the brain to process new information, and since blue light will not be received during that time, it also helps prevent digital eye strain.

Although the use of any form of the blue light filter may be helpful, one sure way to reduce digital eye strain and improve the quality of sleep is to avoid using the computer, smartphone, tablet, or TV for 30 to 60 minutes before bed. Or equip yourself with ViewSonic’s monitors with low blue light technology here.
