does lcd screen harm eyes brands

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.

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.

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.

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.

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.

I’m here to quell your health concerns: staring at a screen doesn’t damage your eyes. They won’t make you go blind, and your doctor isn’t going to worry about your health if he or she hears that you’re spending a lot of time in front of them. However, you might feel uncomfortable after a long time in front of a backlight, and you might even experience the symptoms of Computer Vision Syndrome, a fancy name for the eye strain and discomfort monitors can cause.

You could try adjusting your entire monitor and desk setup to remedy your pain, or you could use moistening eyedrops. The 20-20-20 rule also exists, which dictates that after 20 minutes of screen staring, you should stare at something 20 feet away for 20 seconds. Take a break. Those blue light-filtering glasses you bought could help, too, but doctors aren’t totally convinced. Science just doesn’t back up these glasses’ claims. That said, you could still wear them and hope for the best. They aren’t going to hurt you.

With useful technologies like smart phones, tablets, television screens, and computer monitors becoming so integrated in everyday life, it can be hardnotto inadvertently stare at pixels for several hours every day. We all know that keeping our attention buried in blue light can make our eyes tired after a while, but can too much exposure cause significant problems? Keep reading to learn the effects of screen time on our eyes!

The primary culprit of blue light emissions comes from white LED lights — specifically, the LEDs which backlight the screens of our electronic devices. Light emitting diodes are specifically manufactured to put out narrow bands of colored light which mimics white light. Despite us not being able to see it, a lot of blue light tends to leak out of these handy illuminators, which is why they mess with our circadian rhythms.

“While there’s no strong scientific evidence that blue light from digital devices causes damage to your eyes, there is a growing concern that blue light can have long-term effects on our health,” Dr. LaPlaca said. “Blue light exposure may contribute to the destruction of the cells in the center of the retina and play a role in causing age-related macular degeneration, which can lead to vision loss.”

While blue light and ultraviolet light dohave the potential to be harmful, our personal devices typically emit too low of an amount to cause any major problems. But that doesn’t mean precautions shouldn’t be taken to reduce blue light as much as possible!

When you look at a screen, you might imagine your eyes aren’t doing as much work as when you’re doing things in the physical world. In fact, quite the opposite is true!

Digital eye strain is a growing problem and frequent eye complaint. Just like while reading a book, your eyes are constantly darting back and forth while looking at a screen, jumping between lines of text and clinging to colorful, flashy images. This is a recipe for quick ocular exhaustion!

Likewise, people tend to blink less when using computers and other attention-demanding gadgets. This is because blinking and thinking are related: when our minds are intently focused on something, we blink less often because we don’t want to miss anything. Adding to the problem is the constant brightness of screens which naturally demand fewer blinks to look at. These conditions add up to tired eyes, which need a break from concentration every once in a while.

It’s not just computer screens, either. Research has shown thatanyactivity performed up close for long periods of time can increase the likelihood of developing myopia. Hobbies such as reading, writing, knitting, drawing, and painting can increase your chances of nearsightedness, to name a few.

The solution? Spending plenty of time outdoors and away from screens has proven to be an effective countermeasure against myopia, especially with children and young people. So go out and get some sunshine…but don’t look at the sun!

Because almost all of us need to use digital devices for day-to-day tasks, many people look for ways to protect their tired retinas from prolonged exposure. After all, a lot of workers look at screens for a living!

One popular trick is known as the20-20-20 Rule. Simply put, for every20 minutesof screentime, focus on something20 feet awayfor20 seconds. Working in some blinks will also refresh your eyes with a hydrated tear film before returning to the screen! You may also want to consider using blue light blocking glasses, which are specially made to absorb those harmful wavelengths. Other eye-hacks like downloading blue light blocking plugins, using warm screen settings, and angling your device at least 30 degrees from your eyes can help even more.

Artificial eye drops (without phenylephrine—be sure to check) are another effective method used to combat eye strain. Many over-the-counter brands are harmless when used as needed for immediate comfort. However, keep in mind that most artificial tears are held in bottles which release more solution than your eye really needs. Unfortunately, this is a corporate tactic to exhaust your supply faster, forcing you to buy more.

Nanodropper providesintuitive adaptorswhich fit over eye drop bottles to reduce the amount of drops wasted, saving your wallet and optimizing your eye health at the same time. If you experience frequent eye strain from screens, a Nanodropper Adaptor will quickly pay for itself and save you time and money!

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:

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.

Whether you are working, reading, or mindlessly scrolling social media, screens are our constant companion these days. If you"ve noticed your eyes are feeling more tired, dry, and irritated than ever, that"s because of our new best friend the screen as well. In order to keep our eyes hydrated, our body is internally wired to blink roughly every 13 seconds, releasing the oil that makes up our tear film with every blink. But when we are looking at screens, our blink rates plummet by as much as 66%, meaning less tear film released onto the surface of the eyes, and thus drier eyes. As expected, studies show that people working and reading on screens report significant discomfort. In a 2018 study of 100 medical school students, screen time caused 58.8% of participants to experience eye strain and fatigue, 23.3% reported headaches, and 13% reported blurry vision. In this same study, 75% of the medical students involved stated they would reduce their screen time as a measure to prevent dry eye.

Which screen is the best for your eyes? Studies show that smaller screens with lower brightness settings, like e-readers or smartphones are the best for visual comfort and ocular surface health!

But reducing screen time may not be that easy. Since the onset of the COVID19 pandemic, average screen time use in the United States has skyrocketed, with reports indicating that the average American adult (age 18+) is spending over 13 hours per day looking at screens. That"s up from roughly 10 hours per day reported in 2019 and 8.4 hours per day in 2018. Knowing that cutting screen time when we"re being asked to work from home, attend school from home, and entertain ourselves from home is extremely difficult, can we potentially reduce our symptoms of dry eye by at least choosing the least irritating device to look at?

A new study published in Optometry and Vision Science explored just this and found that the screen that you use does in fact matter! The study looked at the ocular surface health and comfort of 31 healthy adults between age 20 to 26 after reading on a variety of different devices. Baseline measurements of each participant"s ocular surface was taken before using any screen time, including the Ocular Surface Disease Index(OSDI) questionnaire, the Computer Vision Syndrome Questionnaire, tear meniscus height, Schirmer test, noninvasive tear break-up time, tear film osmolarity, bulbar injection (redness), and pupil size. Participants were then asked to read for 15 minutes on a laptop computer screen, tablet, e-reader, or smartphone and the ocular surface measurements and questionnaires were repeated.

Study author Cristian Talens-Estarelles, MSc writes thatthe improved dry eye results with e-readers and smartphones are most likely "attributed to a lower gaze angle and the enhanced optical properties of the e-reader," noting that "the e-reader reflects rather than emits light from behind the screen, similar to how a printed paper behaves."

Smaller screen size.While it may be tempting if your eyes are bothering you to request a larger or even second monitor for work, thinking that a bigger viewing area will make things easier, the science actually shows making monitors larger or using multiple screen monitors is much more uncomfortable for the eyes. In a survey of more than 10,000 adults, only 53% of Americans working on a single screen experienced digital eye strain symptoms, compared to 75% of Americans who used multiple screens. Larger or multiple screen monitors require our eyes to be open wider and slow blink rate down as our brain focuses on peripheral vision to scan between multiple displays.

Lower angle of gaze.Research shows that viewing screens with a downward gaze is the most comfortable for the eyes because it encourages a more natural blink rate. Ergonomic research suggests and optimal screen height of 15-20 degrees below eye level. A disadvantage of larger and multiple screen monitors is that they are typically positioned directly at eye level instead of in this downward position of gaze which increases discomfort significantly.

Lower brightness levels.Reflections from our screens can cause significant visual discomfort, and studies show the screen we are looking at should never be brighter than the ambient room lighting. E-readers and smartphones, especially when Night-Shift mode is enabled, are superior options at reducing reflections and screen brightness to create a more natural viewing environment.

And with any screen use, don"t forget taking breaks is the most important thing you can do. For every 20 minutes that you are working, reading, or playing on a screen, you should take a 20 second break to blink and look down a hallway or out a window (20 feet away). This is called the 20/20/20 Rule and research shows it"s our best protection to keep eyes comfortable and blinking more naturally!

The average American adult spends 11 hours per day looking at a screen. Since the start of the COVID pandemic, this number has ballooned to 13+ hours. Smart phone use and TV watching certainly contribute to this number, but the top culprit for many is the computer monitor.

Because most of us spend hours per day at our computer straining our eyes, the “eye-saving” messages really appeal to us. Almost everyone has experienced dry eyes, strained eyes, blurred vision, or headaches that were caused by excessive screen time. Digital eye strain (“computer vision syndrome”) affects over half of the population.

In truth, most of these “eye-care” and “eyesafe” monitors rely on the two features discussed above — blue light filtering and flicker-free displays. So let’s look into each of these technologies.

First, marketers begin with the statement that blue light is dangerous to our eyes, skin, and sleep patterns. This is factually correct, but somewhat intellectually dishonest.

“It’s true that blue and ultraviolet light are dangerous to eyes, but only at very high intensities.  The amount of blue light produced by a computer monitor or phone screen is so dim that it has no effect on the health of the eyes.  The blue and UV light from the sun is very dangerous and is a documented source of skin cancer, cataracts and retina disease to millions.  This is why doctors recommend sunglasses and sunscreen to people spending significant time outdoors.”– Dr. Norman Shedlo

To summarize: Exposure to high intensity blue light can be harmful. However, a computer monitor only causes a low exposure. It may be helpful to minimize blue light emission from your computer monitor. But this isn’t a technologically advanced feature that justifies your spending extra money.

If you have ever noticed the flicker of a monitor or other display, you will agree that the flicker can be aggravating and unpleasant to look at. But the important question here is whether or not a “flicker-free” monitor does anything to protect your eyes.

Again, we turn to the experts. Dr. Shedlo tells us that “flicker rates between 70-90 Hz will present a screen that does not appear to ‘flicker’. The flickering itself is not dangerous to your eyes, it’s just annoying. Flicker rates above this are outside the range of human perception and make absolutely no difference. These rates have no effect on eye strain.”

Most of the eye strain that occurs happens because of dry eye and decreased blink. So, while special flicker free monitors and monitor lamps seem fancy and may provide a better user experience, from a medical point of view they do not ‘save the eyes.’– Dr. Yuna Rapoport

Even though operating systems (like Windows 10) and third-party applications allow users to reduce blue lighting on their computer monitor, most of us don’t use these features. Therefore, purchasing an “eye care” monitor that automatically includes blue light reduction/filtering may provide some benefit. At worst, this reduction of blue light is neutral, and at best it may benefit our eyes to some degree.

Next, a flicker-free screen may be more comfortable to your eyes. We have established that the flickering of a computer screen isn’t harmful to your eyes. But this flickering can absolutely be irritating to the user. Needless to say, keeping your vision comfortable and aggravation-free during hours of daily screen time is preferrable to an uncomfortable experience.

So, the fact that a number of computer monitors now have this “eyesafe” certification is undoubtedly a positive thing. However, this certification must be taken with a grain of salt.

The TÜV Rheinland stamp of approval only refers to the display’s ability to block, filter, or otherwise minimize the emission of blue light of a certain wavelength. It does not speak to the efficacy of the monitor, or its ability to actually “save” your eyes or reduce eye strain. Instead, it just shows that the particular monitor “passes the test” in terms of limiting blue light.

The concept behind monitor lamps, monitor light bars, and monitor bias lighting is relatively simple. These products minimize the lighting contrast between your monitor and the surrounding area. A bright display in a dark room causes strain on the eyes, so it is better to have some ambient lighting near your computer.

So, these products probably help minimize eye strain when compared to using no monitor lighting at all. But that doesn’t mean that it makes sense to spend $100+ for a specialty monitor light bar that claims it will save your eyes. Ultimately, these monitor lamps and light bars are simply, as Dr. Shedlo puts it, “smaller lamps placed on the monitor to provide lighting to certain places on the desk. Their function can be substituted for by any suitable desk lamp pointed in the right direction.”

Although we have been critical of “eye saving” monitors, increased screen time is a legitimate concern in our society. Excessive electronics use, combined with a lack of physical activity, contributes to numerous developmental, psychological, and physical harms for users.

A 2020 report (which was sponsored by eyesafe, a developer of displays and filters for Dell, Acer, and Lenovo, we should note…) found that 94% of eye care providers are either “very concerned” or “somewhat concerned” about the impact of screen time on patients’ eyes.

Take breaks periodically. Some experts recommend the 20/20/20 rule, which states that after 20 minutes of screen time, you should look at an object that is 20+ feet away for 20+ seconds. This gives your eyes some time to relax.

Eye Care monitors are quickly gaining market share due to their ability to reduce blue light and flicker rate. Because most of us spend hours per day staring at screens, “eye saving” technology sounds like it would be worth every penny.

Some of the new “eye-care” and “eyesaver” monitors are legitimate, high-quality monitors that are worthy of your consideration. But don’t spend a lot of extra money on these products in the hopes of minimizing your eye strain or “saving” your eyes.

We still don’t have a “fix” for the eye strain caused by digital screens. But you can minimize the harms by taking periodic breaks, wearing correct prescription lenses, and adjusting the display brightness and ambient lighting to comfortable levels.

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.

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.

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).

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.

Continuous usage of LCD screens can impact your eyes in few bad ways, that’s why LCD screens are bad for your eyes. For instance, long hours of usage of these screens can cause digital eye strains or the blink rate of your eyes to drop a little. Your eyes can start feeling tired and some sort of blurry vision.

Although, these problems are temporary often, and only get worse in few cases (who doesn’t care for their eyes while using an LCD screen). If you keep blinking the eyes during LCD screen usage, it’ll surely help in keeping them relaxed.

LCD screens (mostly) contains florescent cathode (cold) backlight display, other screen type LED however uses the emitting diodes that are light and are safer over the eyes. Plus, the cathode rays of LCD can be harder on your eyes. So, it is not that safe for the eyes as the other type is.

Experts say that screens like a computer, phone, tablet screens are not that much harmful over the eyes as we think. They can cause temporary damage like blurred vision (for a short time), tiring eyes, redness, etc. that can be resolved with time. But in only a few cases it gets worse but still can be treated.

Although both screen types have their significant pros and cons. But in the case of the eye’s OLED screen is considered a better option. Because they provide better viewing angles, resolution powers, better contrasts, etc. in comparison to the LCD screens.

Discoveries by scientists suggest that LCD screens leak few chemicals almost in every surrounding (environment). And these particles (chemicals) get toxic with time. Also, the breakdown of these chemicals is not easy and takes time, this increase causes a high mobility rate in the environment.are led screens bad for your eyes

“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.

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.

In the past two years, OLED screen smartphones have become the mainstream, and major smartphone manufacturers in the market are applying OLED screens in their flagship models one after another.

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.

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.

If you use the computer frequently and for extended periods then you have likely considered how that is affecting your eyes. If that is the case then you are probably already wondering about the best monitor for eye strain, but if not then I have some information for you!

I"ve been using the computer for about 10 hours a day, almost every day (though maybe a LITTLE less on weekends), for the past 8 years for both work, gaming, and Netflix. During the COVID pandemic of 2020 I found myself on the computer even more... closer to 14 hours a day and noticed how tired my eyes would feel and how my brain would just be SO tired after work.

The VX2457-MHD from ViewSonic is a 24-inch eye care monitor with eye protection as a main priority during development. It natively supports a 1920 x 1080 resolution with a 16:9 aspect ratio. It is a flat LCD monitor with a panel type of TN.

This monitor does have flicker-free technology implemented as well as reduced blue light emission which should protect your eyes from damage and fatigue very well.

When choosing the best monitor for eye strain you must think of that as your primary concern and view the specifications of each potential monitor through that lens. Having in mind that some technologies are better for your eyes than others, check out our best LED monitors review. They come in various sizes. Even some touch screen PC monitorshave features to protect your eyes. For some of the easiest ones on the eyes, check out our

This monitor boasts a wide viewing angle of 178 degrees. This, at first glance, seems like a great viewing angle, and it is, but you have to take these things with a grain of salt. No matter what the advertised viewing angle is on a monitor you should know that, regarding your eyes, the closer you are to being right in front of the monitor the less strain you will have on your eyes. This also makes it a great computer monitor for those with poor eyesight or the visually impaired.

A 178-degree viewing angle essentially means that as long as you are on the screen side of the monitor you can see it without any mutilation of the picture or brightness. After using this myself I wouldn"t exactly go that far, the viewing angle probably isn"t 178 degrees, but it is extremely wide so I am confident in saying that the PB278Q is a good choice for reducing strain on your eyes.

While this monitor isn’t perfect, it is certainly a very strong pick for the best monitor for eyes. It provides a large variety of features that should help to protect your eyes and keep you as comfortable as possible while working with your machine. The only downsides to this monitor are the fact that it doesn’t have blue light reduction and the thicker bezel which will make it less neat and convenient to include in a multiple display setup for increased productivity and efficiency.

The VX2457-MHD from ViewSonic is a 24-inch eye care monitor with eye protection as a main priority during development. It natively supports a 1920 x 1080 resolution with a 16:9 aspect ratio. It is a flat LCD monitor with a panel type of TN. If you are shopping for a compact size monitors, we have dedicated 24 inch monitor reviews.

Much like the last entry this monitor has a 75 Hz refresh time which means, if you are gaming, you might find yourself suffering from screen tearing or visual stutters but this monitor implements FreeSync for those users that use an AMD Graphics Processing Unit (GPU) which locks your monitor’s refresh rate to the frames per second of the game you are playing. This should eliminate those problems which also removes any problem you might have with the refresh rate.

Blue light filtering and flicker-free technology are also implemented which should protect your eyes very well over extended use. The primary problems you will experience with this monitor are the narrower viewing angle and lower contrast due to it being a TN monitor.

I can say that this monitor has a narrower viewing angle which can be annoying if it is implemented in a multiple display configuration. With that in mind, it should also be noted that the bezel on this monitor is thick which doesn"t lend it well toward multiple monitor configurations anyway.

Thankfully, the monitor does come with FreeSync so a more powerful machine can have the framerate it is capable of producing limited to 60 and linked the refresh rate of your monitor. That will ensure that the visuals are smooth with no tearing or stuttering and should keep eyestrain to a minimum as long as you are using an AMD GPU.

This monitor does have flicker-free technology implemented as well as reduced blue light emission which should protect your eyes from damage and fatigue very well.

This monitor does have flicker-free technology implemented as well as reduced blue light emission which should protect your eyes from damage and fatigue very well.

It has a refresh rate of 60 Hz and a 1 millisecond response time. It comes with FreeSync compatibility as well which should keep your eyes protected during extended use.

Samsung’s proprietary Eye Saver Mode monitor settings to reduce eye strain is supported with this monitor and is supposed to reduce blue light emissions and flickering but I am unsure how effective it is. I can confirm that I have never had any eyestrain problems while using this monitor.

The 6 millisecond response time is slow and might cause issues for your eyes as they process the minor delay. Fortunately, this monitor does come with its own kind of flicker protection and blue light filter which should help to mitigate or at least counterbalance the strain you may experience from the delay.

You might have considered, “what is eye strain?” It is caused by overworking your eyes to process visual stimulus and usually results in headaches and eye fatigue.

If you are a gamer then you may want to look at response times and refresh rates more, but you should be looking at eye protection first and gaming second. If you are a working professional in graphic design or video editing you may be more concerned with contrast or image quality of the monitors which are best for video editing, or the best monitors for graphic designwe also reviewed. You should also look at things like viewing angle and what kind of eye protection software it is compatible especially even with the best curved monitor you just got which may feel strange to your eyes until you adapt..

The size of your monitor might affect how long you can use the computer without straining your eyes. An extremely large monitor will mean that you have to move your eyes more to see everything which can significantly contribute to eye fatigue over extended periods. That said, a very small monitor will have a lower screen resolution which means images displayed on it will be smaller and will require more focus and precision for your eyes to be able to see them which can also contribute to strain.

This is very much a Goldilocks situation, where you don"t want something too big or too small, but something just right. Unfortunately, this is a very subjective situation and the only way to be able to tell exactly what size is right for you is by trying many and monitor eye strain while using them. There are many factors to consider here such as the space you work in, how much room there is for different monitor sizes, how far away you sit from the screen, and the angle that you usually view it at.

Contrast, when discussing monitors, is usually about the vibrancy and number of hues of colors that a monitor is capable of showing. The higher the contrast ratio is the darker the blacks and brighter the whites will appear on your screen which consequently means the more shades and hues of colors it will be able to display.

Response time is about how long it takes for a monitor to understand and then display your inputs. Mostly this is noticed based on how long it takes your mouse to move on the screen after the mouse moves on the mousepad or how long it takes for characters to appear on your screen after you press keys on your keyboard.

Viewing angle is referring to how you are looking at your screen. If you typically sit directly in front of your screen and look at it head-on then you probably won"t have any issues with any monitor. If, however, you often sit leaned back very far in your chair, as I do, then you may notice that certain monitors will look different and often have problems like shadows appearing where they shouldn"t and colors being washed out which can cause computer eye strain and headaches.

Overall, the main way that panel type will affect your eyes is in how the panel type affects the viewing angle which in turn will affect all of the other qualities. A Twisted Nematic (TN) display has a narrower viewing angle and a lower contrast than an IPS monitor which means that your eyes have to work harder to analyze all of the information on the screen than they would with an In-Plane Switching (IPS) monitor type which generally has greater contrast and a wider viewing angle.

All of that said, what matters here is the viewing angle. As I said previously if you are looking at the screen head-on most of the time then the panel type won"t matter, but if you frequently look at it from an angle then the panel type will determine how much eye strain you will receive over time.

Monitor refresh rate determines how often your monitor will "refresh" the image on the screen. You will see a 60 Hz refresh rate more often than any other which means the monitor is refreshing the image 60 times per second.

The slower the refresh rate of your monitor the more likely it is for flickering to happen which means your eyes will have to work harder to mitigate that. Generally speaking, a higher refresh rate is better but the standard of 60 Hz should be fine concerning your eyes. A gaming monitor for sensitive eyes should should begin at 120 Hz or more.

The primary concern when it comes to protecting your eyes from extended computer use is blue light. Blue light is a common type of light emitted by most computer screens and it is a very damaging wavelength for your eyes to process. Thankfully there have been advances in software that allow for a lot of that blue light to be filtered out and thereby protect your vision from receiving further damage. Monitor companies can’t make money if all of their users are going blind, how thoughtful of them!

Another thing to consider is flickering. Monitors work by shining light in sequence so quickly that to your eyes it looks very much like a still image, but in truth, it is moving so rapidly that your eyes can"t process it. If a monitor is made without considering this then your eyes may notice the flickering and experience strain or fatigue by trying to process it all even if you don"t notice it yourself.

You can move and reposition the monitor using ergonomic design so that it is at eye level. After all, it"s crucial to avoid straining your neck. Consider purchasing a monitor with VESA mounting capabilities and an adjustable monitor arm if you"re looking to fine-tune your ergonomic setup so you can place your screen comfortably in front of you without having to tilt your neck up or down.

Computer screens are harmful to your eyes and the longer you use them the more damage you are causing to yourself. If you aren’t concerned about your eye health then you may be more interested in saving yourself some money, consider these monitors for a tight budget! When you are out and about, we recommend getting one of the top-rated portable monitorswe reviewed.Most users will likely find this damage to be negligible, they likely won"t even notice it except over very long periods. That said, those users with more sensitive eyes will notice a decline in the quality of their vision, like me even when using top-rated PC monitors. Fortunately, monitor companies know this and there have been advances in technology that should help to mitigate the damage caused by extended computer use.

In addition, read our computer monitor arm reviewsfor better screen positioning and even less eye strain.You might also consider checking out some quality freesync monitors as well as some of the top of the range HDR monitors we reviewed here.

Yes, when using digital devices, you can adjust your environment to promote healthier eyes. If possible, reduce eye strain by using a large monitor or screen magnifier. Ascertain that your chair is adjacent to your computer and that you are seated in a chair that provides adequate lower-back support.

(AM)OLED monitors are the best for the eyes due to its high contrast level and per-pixel light emitting diodes. The second best option is probably TFT: *VA (e.g. AMVA, PVA) panels with a high contrast ratio and a non-PWM LED backlight. TFT: IPS is acceptable, but only in certain circumstances.

TVs and monitors both have potential to cause eye fatigue, but TVs are more likely to do so. The main difference is that TVs emit harmful blue light, which can be more tiring for the eyes than other colors. If you"re going to be spending a lot of time in front of a screen, it"s a good idea to invest in a monitor with low blue light emissions.

In terms of eye safety, image quality, and power consumption, LED displays far outperform LCDs. The conventional LCDs employ a cold fluorescent cathode display backlight, whereas the LEDs use light-emitting diodes. LED backlighting is significantly more compact and eye-safe than incandescent lighting.

You should position the screen at the end of your fingertips while extending your arm and hand straight out from your shoulder. Without having to squint or strain to read small text on the display, this will lessen strain brought on by having to focus on objects that are too close to you. Of course, everyone is unique, and depending on your particular biology, you might discover that being a bit closer or farther away is more pleasant.

When deciding projector vs TV, eye health is a major consideration. Screens like TVs produce eye-damaging direct blue light. A projector’s Indirect light – even its indirect blue light – is much gentler on the eyes. Along with other safety features – which you can learn about below – projectors are the best option based strictly on eye health.

Projectors vs. TVs, which should you choose for your next home entertainment setup? There are many important factors to consider such as cost, screen size, and image quality, but those are features of the product itself. What about consideration to effects of the product on the user, in this case, you and your family, who will be spending hours enjoying TV programs, movies and streaming content on your new home entertainment system? If selecting a solution that will have the least effect on your health, especially your eyes, there are some issues you may not have considered before.

Blue light should be the first concern for people addicted to screen time. We spend hours at work, school, and home with our eyes glued to screens, and the largest screens we have are our TVs. LCD, LED, and all the other TV varieties emit blue light, which especially at night has detrimental effects on our health. With the average adult in the US watching live TV for over 4.5 hours a day according to research firm Nielsen, the amount of blue light we are receiving from our TV is pretty high.

According to www.bluelightexposed.com blue light is a cause of digital eye strain, a medical issue with serious symptoms including blurry vision, difficulty focusing, dry and irritated eyes, headaches, and neck and back pain. Additionally, long-term effects show that high levels of long-term blue light exposure may cause permanent eye damage and contribute to the destruction of the retina and macular degeneration.

Blue light is a wavelength of light found in natural sunlight and artificially from things that emit light such as lightbulbs, computer screens, and TVs. Although most of the wavelengths in blue light are safe for your eyes, high-energy blue-violet light in the 415-455nm band is more damaging to the eyes, especially the lens and retina. This range of blue light falls under UV intensity, which is widely known to be harmful to the human body if overexposed (one of the reasons we get sunburns). Sadly, wearing UV blocking sunglasses would not be ideal when trying to watch your favorite movie or show.

One way to cut back on blue light exposure is to cut back on your screen addiction. The likelihood of this happening is slim. The same Nielsen report indicated that the average American adult spends more than 10 hours a day consuming media on the screen. Cutting back is very unlikely or impossible for most people, especially if people have to work with a computer then spend the rest of the day checking their smartphones and watching a favorite TV show when they get home.

An alternative to blue light-emitting TVs is projectors. Projectors do produce blue light but since you will not be staring straight at the light source while viewing this light does not hit your eye directly. The light bounces off another surface (a projector screen or wall) before hitting your eyes; this surface absorbs some of those damaging wavelengths, reducing the amount of blue light that actually reaches your eyes.

Light sources can be divided into two kinds based on the path taken to your eyes: direct and indirect light. Most of the light sources we encounter daily from the fluorescent lamps above your heads to the TV screens in your living rooms are direct light emitters. This means these items produce light and it is traveling directly to your eyes. Direct light sources are harsher on your eyes in comparison to indirect light. To illustrate, staring at a flashlight beam directly is a lot more uncomfortable than staring at that light bouncing off a wall. Projectors utilize reflected light, which is less invasive to your sight and reduces eyestrain and other negative effects of prolonged viewing.

Projectors screen size can readily create images larger than what is possible for TVs; a screen of over 100 inches or even 200 inches can be produced easily. For those looking for eye comfort, projectors’ large screens are even better. Larger screens create images that are bigger and more comfortable for the eyes to view. Cutting down the need to strain your eyes to see details. For text, like subtitles, it is even more beneficial. Larger letters make things a lot easier to read. Altogether, projectors offer larger screens, reduce blue light, bypass direct light, and utilize reflective light, which equals a much more comfortable viewing experience compared to TVs.

To summarize, in the comparison of TVs vs. projectors, the projector offers much more flexibility while being much safer for viewers’ eye health. Projectors reduce the effects of blue light and direct light while also offering adjustable screen projection size, and newer projectors have smart safety features to avoid accidental eye injury.

If you are considering a new TV or projector, consider the effects they have on your eyes. Take a break from the many screens in your life and try a projector. Learn more about ViewSonic projectors here.

Computer vision syndrome (CVS) is a common modern problem describing the eye discomfort that comes from viewing screens. Its symptoms include eyestrain, headaches, and neck or back pain among others. Techniques for reducing computer vision syndrome include everything from using the right hardware to good workspace design. We have the full list of tips for protecting your eyes below.

With today’s digital lifestyles, our lives revolve around the use of technology, and our eyes are working harder than ever before. Our daily digital routines are creating significant health problems like Computer Vision Syndrome.

You probably recognize this routine—stare at the computer screen, look down to your phone, return to the computer screen. Watch a movie on a tablet, then turn your attention back to the computer screen.

Studies show that the average American worker uses a computer for work or recreation, or a combination of both, for close to seven hours a day! Unfortunately, prolonged exposure to digital displays affects the health of our eyes, creating discomfort in the short-term and leading to more significant issues down the line.

This activity can lead to a type of eye strain known as Computer Vision Syndrome (CVS), a term that encompasses a range of ocular issues. A way to reduce CVS is the reduction of continued exposure to screens. Unless we change our routines, the effects can be severe and the damage long-lasting.

Selecting the right computer monitor may be one of the healthiest eye practices of all. The right monitor can limit or prevent the harmful effects that lead to digital eye strain while creating a more enjoyable viewing experience and a more ergonomic work environment. When viewing a screen is a more enjoyable activity, it’s also a healthier one.

The symptoms of eye fatigue and discomfort from Computer Vision Syndrome are temporary. They will dissipate within a few hours once you stop using computer screens.

Digital screens emit a blue light that is stronger, brighter, and at a higher level of energy than the yellow light we receive from daylight or most lightbulbs, as well as other light waves in the visible light spectrum. Blue or “HEV” high energy waves of light flicker due to this higher energy, causing a decrease in visual clarity, and contrast.

The blinking or flickering of the screen creates a glare that leads to eye strain, dryness, discomfort, and eye fatigue, as well as a host of other symptoms associated with digital eye strain.

As technology advances, more and more digital screens now use LED-backlighting, which helps create higher image quality and clarity than in the past. This LED light that creates stunning visual definition, graphics, and contrast; sounds great at first. Unfortunately, LED light also emits intense and potentially harmful blue light waves.

Our eyes are not naturally equipped to filter out harmful blue light from digital displays and monitors. With the increasing prevalence and popularity of LED technology, we are experiencing higher and more prolonged levels of exposure to dangerous blue light waves and compromising the health of our eyes over time.

ViewSonic has vigilantly worked to create a line of computer monitors engineered with various innovative technologies to keep our eyes protected. The following are the most important features to prevent CVS.

View Sonic monitors use advanced light-filtering technology to reduce exposure to harmful blue light. Blue Light filter technology helps keep blue light waves at levels that are closer to realistic and everyday colors.

A range of 100 filter levels allows the display’s light to easily and flexibly adjust to different viewing scenarios, while successfully filtering out harmful levels of blue light.

View Sonic monitors and displays also incorporate flicker-free technology to help maintain eye health. This revolutionary technology uses DC-modulation LED backlights to reduce and eliminate screen flickering.

Creating an ergonomic workstation is essential to ensure the long-term health of your eyes and your general health while helping maximizing work productivity. Below are some ideas to improve your working experience and put you on a path for a Computer Vision Syndrome cure.

It is important not to sit too close or too far from the computer as you work to prevent eye strain. The American Optometric Association advises that the healthy viewing distance should be 15 to 20 degrees below eye level, as well as 20 to 28 inches away from the eyes.

In a poorly lit environment, you will naturally strain your eyes to read your computer screen. Overhead lighting and natural light from windows can potentially create a glare on the screen, so position any monitor in a location that will reduce glare.

In environments where there is too much light to minimize glare, it may be necessary to use an anti-glare screen to ensure a comfortable viewing experience. ViewSonic offers a line of privacy screen protectors that help create an anti-glare surface, reducing eye strain and improves privacy.

Poor posture can impact your viewing experience of your digital display, causing you to strain your eyes. Create a more ergonomic workstation by adjusting your posture. Your chair and screen should be at the right height so that you can rest your feet comfortably on the floor.

To reduce and prevent eye strain, it is necessary to take breaks between the use of your digital device so that your eyes can rest. According to various medical sources, it is advised to follow a 20-20-20 rule during the use of your digital device. Every 20 minutes, take a 20-second break and focus your eyes 20 feet away from your digital device. By turning your eyes away from screens, the muscles in your eyes get the chance to relax properly.

As important as it is to take breaks during the use of a computer monitor, you can easily relax and refresh your eyes from the simple act of blinking as well. Blinking is beneficial because it helps produce tears to alleviate or prevent dryness and bring moisture back to the eyes.

The first step to ensuring the long-term health of our eyes is to be aware of the prevalence of Computer Vision Syndrome and understand how all aspects of your workstation affect your viewing experience.

Let’s start taking control of the health of our eyes so that we can build a healthier and more productive—all-be-it digitized— future. See you on the flipside!

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.
