tft lcd eye strain brands

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.

As we mentioned in our Asus VP28UQG review, the display size of 28 inches, 3840 by 2160 resolution and a 16:9 aspect ratio make this 4k monitor a solid choice with eye care in mind. It is a TN panel LED monitor.

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 24-inch monitor from BenQ is a flat LED with an IPS panel type. It uses a proprietary eye care technology that is supposed to reduce blue light and flickering.

This is a 27-inch monitor from BenQ for home and office work with eye care as a priority during development. It is a 1440p monitor and the aspect ratio is 16:9.

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

It has a slower response time of 5 milliseconds but it should serve without issue for all uses besides gaming. You could play games with this monitor casually, but you may notice a delay that might cause eye strain over extended periods. The refresh rate is 75 Hz which is higher than most monitors.

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.

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.

For the price, this monitor is a fantastic option for eye-care protection. It should be fairly versatile while also being a great choice for a casual gamer but I do not recommend it for professional work in photography or graphic design of any kind. This is because the TN panel type holds it back from having a high degree of color accuracy or contrast.

The VP28UQG from ASUS has a display size of 28 inches and has a 3840 by 2160 resolution with a 16:9 aspect ratio. It is a 4k monitor created specifically with eye care in mind. It is one of the best computer monitors for elderly people. It is a TN panel LED monitor.

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.

It uses a proprietary eye care technology that is supposed to reduce blue light and flickering. The viewing angle is wide and it has an automatic method for adjusting brightness for the most comfort and least strain.

The GW2765HT is a 27-inch monitor from BenQ for home and office work with eye care as a priority during development. It is a 1440p monitor and the aspect ratio is 16:9. It is a flat LED monitor with a panel type of IPS.

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.

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.

Panel type has a small part to play in eye strain and fatigue, but it has more to do with how the panel type affects the previously mentioned qualities rather than the panel type itself.

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.

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.

So, the main thing you should be looking for is eye care technology. There are two types that you will likely find, "Flicker-Free technology" and "Low-blue Mode" or "Blue Light filter technology", something to that effect.

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. If you are looking for a monitor from a renown brand, check out our best BenQ monitor reviews. 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.

No, curved displays are beneficial to the eye. Apart from alleviating eye strain, a curved monitor provides a more immersive experience and enables peripheral vision. The edges of a sizeable visual canvas are visually drawn in and equally spaced apart so that users do not have to swivel their heads to take in all the content.

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.

The best monitors for eye strain those that are easy on the eyes, so an easy way to counter the harmful effects of staring at your computer all day is to switch to using a curved monitor. Curved monitors provide less distortion, a wider field of view, and better viewing angles to prevent you from tiring out your eyes.

Bottom Line: If your eyes hurt from staring at computers all day, consider getting a curved monitor that lets you take in the whole picture at once without straining your eyes. We recommend the ViewSonic® VP3881 or VP3481.

If you’re one of the millions of people who spend long hours in front of the computer, chances are you’ve probably experienced eye strain. Digital eye strain (also known as computer vision syndrome) occurs when your eyes become “tired” from staring at digital devices for an extended period of time.

In this article, we’ll cover what digital eye strain is and how it’s harming both employees and businesses, the best type of monitor for eye strain, and our top three choices for monitors that prevent eye strain.

According to the American Optometric Association, digital eye strain encompasses a wide range of symptoms. In addition to visual fatigue, digital eye strain also includes symptoms such as:

Digital eye strain also costs businesses thousands of dollars in lost productivity every year. According to the Optometry Times, eye-focusing problems cost businesses more than $2000 annually per employee.

While people normally blink an average of 12 times a minute, when staring at a computer screen, blinking drops down to five times a minute. This lowered rate of blinking can cause discomfort and lead to dry eyes.

One often-cited anecdote for reducing eye strain is to limit screen time. While this is a sound tip, it’s also impractical for the millions of people that use computers daily for work.

According to research performed by Harvard Medical School, participants who used curved monitors reported experiencing less eye strain than subjects who used flat monitors. Blurred vision was also 4x less common in users of curved monitors than users of flat monitors.

Curved monitors are monitors that come with a curved screen to provide users with a more immersive experience and a wider field of view. These monitors help relieve eye strain by enabling viewers to take in the entire monitor display at once without straining.

As long as you’re using a curved monitor, and your eyes are easily able to take in the entire display without straining, curvature rating is more of a personal preference rather than a health-related one.

Using ergonomic monitors is critical to maintaining your health as non-ergonomic monitors can lead to eye strain, stiff necks, sore backs, and a host of other ailments.

Rather than craning your neck and straining your eyes to look up at the monitor, ergonomic monitors can be easily adjusted to your ideal viewing angle. When searching for an ergonomically curved monitor to help you fight off eye strain, try looking for a monitor with swivel, tilt, and height adjustment features.

Blue light is a type of short-wavelength, high-energy light emitted by computer monitors and other digital screens. Studies have shown that in addition to exacerbating eye strain, blue light can also have a negative effect on sleep.

Blue light is most disruptive at night, where it can suppress the secretion of melatonin – the hormone responsible for making us tired and sleepy. When looking for a monitor to combat eye strain, try searching for monitors that come with a blue light filter to preserve your circadian rhythm and ease the burden on your eyes.

Though ViewSonic’s curved monitors are optimized for a wide array of uses from gaming to business, these monitors can help relieve digital eye strain no matter what task you’re performing.

Its 2300R curvature and anti-glare coating enable you to comfortably view the entire screen from up to two meters away without straining your eyes, while its ergonomic design empowers you to adjust it to your preferred viewing level. Give your eyes a break and use the VP3881 to quickly finish your day-to-day tasks.

In this post, we went over the causes and symptoms of eye strain and covered why curved monitors are essentially one of the best defenses you can have against digital eye strain. We broke down the key elements to look for in a curved monitor and highlighted some of our top choices. To learn more about ViewSonic’s monitors, click here.

I understand. I was hoping, that someone else with a similar sensitivity as me, could perhaps suggest a technology that is very similar to the aforementioned CCFL-backlit screen. A technology that is easy on sensitive eyes. Like my AMOLED screen on my Samsung Galaxy S2 phone or S2 Tab. It is also relatively mild on the eyes, for me at least.

Not to sound rude but, I am getting a bit tired of people who think that I need a: flicker-free, IPS, high resolution, or whatever monitor and that the problem will magically go away. I tried so many different monitors, and somehow, the only one that my eyes can fully handle is the TFT LCD (as I wrote in my original message).

I have never seen a regular PC monitor that looks like the one on the pictures that I posted. Dark green, glossy, visible "pixels". So I am starting to wonder what was so special about those monitors back then. And which current technology could be a good replacement. (eye sensitivity wise)

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?

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.

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!

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) we are talking here is TN (Twisted Nematic) type TFT displays which is align with the term in the TV and computer market. Now, TFT displays have taken over the majority of low-end color display market. They have wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, consumer electronic products etc. For more information about TFT displays, please visit our knowledge base.

Talking about Pros and Cons of TFT displays, we need to clarify which display they are compared to. To some displays, TFT displays might have advantages, but compared with another display, the same character might become the disadvantages of TFT displays. We will try our best to make clear as below.

Excellent physical design. TFT displays are very easy to design and integrated with other components, such as resistive and capacitive touch panels (RTP, CTP, PCAP) etc.

Minimum Eye Strain: Because TFT panel itself doesn’t emit light itself like CRT, LED, VFD. The light source is LED backlight which is filtered well with the TFT glass in front for the blue light.

More Energy Consumption: Compared with monochrome displays and OLED (PMOLED and AMOLED) display, which makes TFT displays less attractive in wearable device.

Poor response time and viewing angle: Compared with IPS LCD displays, AMOLED displays and recent micro-LED display. TFT displays still need to note viewing angle of 6 o’clock or 12 o’clock in the datasheet and still have the gray scale inversion issue.

High tooling cost: Depending on which generation production line to produce and also depending on its size. Building a TFT display fab normally need billions of dollars. For a big size display which needs high generation production line to produce. The NRE cost can be millions dollars.

Sunlight Readability: Because it is very expensive to produce transflective TFT LCD displays, in order to be readable under the sunlight, very bright LED backlight (> 1,000 nits) has to be used. The power needed is high and also need to deal with heat management. If used together with touch panel, expensive optical bonding (OCA or OCR) and surface treatment (AR, AF) technologies have to be used.

This 32” RLCD computer monitor is the first in the world of its kind! Made primarily for those who experience discomfort from backlit monitors, it combines familiarity with groundbreaking innovation.

TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.

TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.

There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.

In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.

The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.

Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.

The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

As a leading manufacturer and distributor of high-quality digital displays in North America, Nauticomp Inc. can provide custom TFT LCD monitor solutions that are suitable for a multitude of industrial and commercial indoor and outdoor applications. Contact us today to learn more.

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.

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.

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.

According to statistics, a modern person uses a PC or smartphone for up to 10 hours a day. Of course, this mode significantly increases the load on the eyes. Therefore, this aspect excites many people.

Usually, a person blinks about eighteen times per minute. This frequency provides constant hydration with tear fluid. But while working on any display, a person on average blinks only 2-3 times per minute. Accordingly, hydration is reduced by almost 10 times. As a result, the eyes begin to watery.

Myopia due to eye fatigue, can be true or false. False myopia due to spasms of the eye muscles reduces the clarity of image perception. But these sensations quickly disappear even after a short rest. Unfortunately, the constant tension of the eye muscles provokes the occurrence of true myopia, in which the shape of the eyeball is slightly elongated.

In this case, the person is forced to constantly use glasses. But choosing a model with optimal screen can minimize these risks. Of course, camera, smartphone performance, smartphone storage, operating system, price, etc remain the main criteria when choosing a model. But screen with optimal PPI (pixels-per-inch), brightness and backlight technology will reduce eye strain.

In terms of ophthalmology, eye fatigue is inversely proportional to image clarity. In other words, the eye strains as much as possible when viewing a blurred image. As known, PPI is the ratio of resolution (in pixels) to diagonal size (in inches) and directly affects the image clarity. Therefore, a small screen with high resolution requires much less eye strain compared to a large screen at low resolution. In fact, at low resolution the eye is constantly forced to adjust the sharpness, which leads to fatigue of the eye muscles.

For example, the PPI of a 4.3-inch HD (720 × 1280) screen reaches 342, and the PPI of a 4.7-inch HD display does not exceed 312. Accordingly, the first model will be more comfortable for the eyes.

But the screen brightness also depends on its type. For example, LCD screens use continuous backlight technology. Therefore, the bright light from the backlight LEDs constantly affect the eyes.

As known, all OLED displays, including AMOLED, Super AMOLED, Super AMOLED Plus, P-OLED and Dynamic AMOLED, use their own radiation from organic diodes and do not have a backlight. As a result, the eye perceives light only from active pixels on the screen. At the same time, all other screen pixels are completely black. Of course, such a screen has a minimal effect on the eyes. But many users consider the higher brightness of the LCD vs AMOLED a plus.

Thus, OLED models with high PPI minimize eye strain. But today only expensive models have large screens with high PPI. Mid-budget models provide no more than 300 ppi for 5-inch screens. In addition, the relatively low brightness of OLED screens reduces the saturation of colors.

Overall, protection eyes when working with gadgets is becoming one of the main trends in this segment. Today manufacturers have already significantly lowered blue light level, Xiaomi is successfully developing DC Dimming (flicker reduction) , and many companies offer flicker-free AMOLED smartphones.

In particular, IPS screens are the eye safest because they use high frequency PWM (Pulse Width Modulation) to adjust brightness, which exceeds 2,000 Hz. For comparison, ophthalmologists consider a pulsation frequency of 300 Hz and higher to be safe.

AMOLED displays use a lower frequency. For example, many budget smartphones with AMOLED screens use frequencies below 240 Hz. As a result, the eye perceives screen flickering, which increases fatigue. Today, the list of models with AMOLED or Super AMOLED matrix and with an eye-safe PWM frequency includes:

The Fellowes Compact TFT/ LCD Monitor Riser is suitable for use with either flat screen TFT or LCD monitors and has been ergonomically designed to help reduce shoulder, neck and eye strain. The unique height adjustment allows for individual customisation from 76mm to 114mm to ensure a comfortable viewing angle can be adopted. The monitor platform is able to rotate 45 degrees to accommodate quick and easy shared viewing of the screen.

Pulse Width Modulation is something you will hear talked about quite a lot nowadays. We have a full detailed article about PWM which is worth reading through. In simple terms, PWM is a method used for dimming a monitors backlight whereby the backlight is turned off and on rapidly to simulate lower brightness levels. As you decrease the brightness setting of the screen the “off” periods are increased in length progressively and this in turn leads to a lower luminance output for the display (darker image). The problem with PWM is that on modern LED backlights the rapid turning of the backlight off and on can lead to flickering. Sometimes when the frequency of the PWM is low this might even be visible to some users. In other cases, while it might not be visible the user may still experience unwanted side-effects of its use including eye-strain, headaches, eye fatigue and even nausea.

To overcome this, many manufacturers now actively promote their use of flicker-free backlights and have done away with PWM completely. If you are sensitive to the use of PWM or are just worried about your eye health, we would certainly recommend trying to avoid displays where PWM is used.

While TFT screens are best run at their native resolutions, it is possible to run them at lower resolutions if need be. In doing so the screen must interpolate the image from below the native resolution, leading commonly to some loss in image clarity and sharpness as the image is stretched across pixels. In office use this can be a problem and can look quite poor, but in gaming, it is generally not so much of a problem. The ability of a TFT to interpolate the image depends on the particular panel and scaler used, and some manufacturers have been able to improve the ability of their panels to run outside the native resolution. Generally though it is not recommended to run outside the native resolution on a TFT if you can help it. Where resolutions are very high (e.g. Ultra HD / 4K) then you will still want to run the display at the full native resolution, but enabled operating system scaling to make everything easier to see.

On modern IPS panels when viewing a black image there is typically a characteristic white glow when viewed from an angle, commonly referred to as “IPS-glow”. This is common on most modern IPS-type panels and can be distracting to some users. The level of glow shown here is pretty typical of a modern IPS-type panel. If you view dark content from a normal head-on viewing position, you can actually see this glow slightly as your eyes look towards the edges of the screen if it is of a large size. The wider the screen and the bigger it is, the more likely you are to see some glow from your normal viewing position as you glance towards the edges. A curve to the screen can help reduce this a little as the angle between your eyes and the edges is reduced a little. Some people may find this IPS-glow problematic if they are working with a lot of dark content or solid colour patterns. In normal day to day uses, office work, movies and games you probably wouldn’t really notice this unless you were viewing darker content. If you move your viewing position back, which is probably likely for movies and games, the effect reduces as you do not have such an angle from your eye position to the screen edges.

The Screen Door effect is so called because sometimes it is possible to clearly see the individual pixels in a panel and the gaps between them. This is quite rare, but can be distracting if you are using a TFT up close. It may be more apparent where pixel pitch is large (e.g. a large screen with a relatively low native resolution / number of pixels in the matrix).

Input lag is described as the lag between the output from a graphics card and the image which is displayed on the screen you are using. For LCD screens this should not be confused with pixel response time which describes the speed at which a pixel can change from one orientation to another. Pixel response times impact aspects such as motion blur and ghosting in moving images. On the other hand input lag is a delay between what is sent to the monitor, and what you actually see. This can have impacts particularly in gaming where if the screen is lagging at all, it can have adverse affects on first person shooter games and the likes where every millisecond counts. Lag is more about the ‘feel’ of delay.

The level of lag really depends on the TFT display, and is controlled by many signal processing factors including, but not limited to the internal electronics and scaling chips. Some manufacturers even take measures to help reduce this, providing modes which bypass scaler chips and options which reduce the input lag. These are often reserved for gamer-orientated screens but the results can be quite noticeable in some cases. Where NVIDIA G-sync modules are used you will tend to see very low levels of lag as well, as the screen does not have a scaler present.

Cleartype was introduced by Microsoft for use with LCD displays to make fonts more rounded and less jagged. This is effectively a filter used to blur the fonts a little which some people prefer the look of. This can vary from one TFT to another, and it is easy enough to turn on and off to allow you to decide which you prefer. Microsoft’s article about the Cleartype filter can be found here:

Image burn in was traditionally a problem with CRT displays, where prolonged images on the screen could leave a ghost image behind after it has changed. This was a problem with older CRT displays and was the reason for the introduction of screen savers. With TFT’s this is not really a major problem as the image cannot be burnt into the screen by the cathode ray gun, as the pixels all operate individually. Some screens can very occasionally show some lasting imprint of an image if the same picture is left on the screen for long periods of time, but it is generally not permanent. This can often be easily solved by looking at some fast moving scenes or gaming. For the sake of electricity more than anything else though, it is probably easiest to use the power settings on your PC to turn the screen off when not in use.

One of the main concerns people have when buying a TFT relates to the problem of dead pixels. Pixels can sometimes be ‘dead’ (stuck on black or white). Sometimes the sub pixels which make up the pixel can be dead which leaves the pixel looking red, green or blue. Sometimes the sub pixels can be ‘lazy’ and with a bit of luck can come back to life.

Dead pixels / sub pixels defects are normally caused during the manufacturing stage, and it is very rare for a panel to generate a pixel fault at a later stage unless you have a tendency to prod the screen. Nowadays, manufacturing levels are very good and it is quite rare for a pixel to be ‘dead’, and you will see some manufacturers like Samsung and ViewSonic for instance, offering zero dead pixel policies. Dead sub pixels are still a problem, and the policy will not cover these in most cases. Dead pixels are not really considered a fault with a TFT monitor and you will need to consider this before purchasing. Refer to the manufacturer to find out what their dead pixel policy is.

The OSD refers to the “On Screen Display” available on nearly all TFT monitors. This allows the user to change settings ranging from brightness, contrast and colour levels (typically RGB) to more advanced features like aspect ratio and monitor preset modes instance. One thing to note is that some features like contrast, phase and pixel clock are only available when using the VGA (analogue) interface and become greyed out when using the DVI (digital interface) as they are no longer required. Proper configuration of a monitor requires RGB levels to be altered and brightness and contrast to be set correctly. More advanced features are often accessible and modern OSD often offer a wealth of selections. Some OSD also offer factory menus and information about the screen or panel being used which can be particularly useful for the enthusiast.

It is possible to detach the stand from some TFT models and instead mount them to a swinging arm on a wall or desk. If this is something you might wish to do, look for TFT’s which specify compatibility with VESA mounts. These can provide improved alignment of a monitor and easier use depending on your needs.

The wide range of conditions over which LCD monitors are used means that it is desirable to produce displays whose luminance (brightness) can be altered to match both bright and dim environments. This allows a user to set the screen to a comfortable level of brightness depending on their working conditions and ambient lighting. Manufacturers will normally quote a maximum brightness figure in their display specification, but it is also important to consider the lower range of adjustments possible from the screen as you would probably never want to use it at its highest setting. Indeed with specs often ranging up to 500 cd/m2, you will certainly need to use the screen at something a little less harsh on the eyes. As a reminder, we test the full range of backlight adjustments and the corresponding brightness values during each of our reviews. During our calibration process as well we try to adjust the screen to a setting of 120 cd/m2 which is considered the recommended luminance for an LCD monitor in normal lighting conditions. This process helps to give you an idea of what adjustments you need to make to the screen in order to return a luminance which you might actually want to use day to day.

Changing the display luminance is achieved by reducing the total light output for both CCFL- and LED-based backlights. By far the most prevalent technique for dimming the backlight is called Pulse Width Modulation (PWM), which has been in use for many years in desktop and laptop displays. However, this technique is not without some issues and the introduction of displays with high brightness levels and the popularisation of LED backlights has made the side-effects of PWM more visible than before, and in some cases may be a source of visible flicker, eyestrain, eye fatigue, headaches and other associated issues for people sensitive to it. This article is not intended to alarm, but is intended to show how PWM works and why it is used, as well as how to test a display to see its effects more clearly. We will also take a look at the methods some manufacturers are now adopting to address these concerns and provide flicker-free backlights instead. As awareness grows, more and more manufacturers are focusing on eye health with their monitor ranges.

Pulse Width Modulation (PWM) is one method of reducing the perceived luminance in displays, which it achieves by cycling the backlight on and off very rapidly, at a frequency you can’t necessary detect with the naked eye, but which could lead to eye issues, headaches etc. This method generally means that at 100% brightness a constant voltage is applied to the backlight and it is continuously lit. As you lower the brightness control the perceived luminance for the user reduces due to a number of possible controlling factors:

Where the effect of flicker can really come into play is any time the user’s eyes are moving. Under constant illumination with no flickering (e.g. sunlight) the image is smoothly blurred and is how we normally perceive motion. However, when combined with a light source using PWM several discrete afterimages of the screen may be perceived simultaneously and reduce readability and the ability of the eyes to lock onto objects. From the earlier analysis of the CCFL backlighting we know that false colour may be introduced as well, even when the original image is monochromatic. Below are shown examples of how text might appear while the eyes are moving horizontally under different backlights.

It is important to remember that this is entirely due to the backlight, and the display itself is showing a static image. Often it is said that humans cannot see more than 24 frames per second (fps), which is not true and actually corresponds to the approximate frame rate needed to perceive continuous motion. In fact, while the eyes are moving (such as when reading) it is possible to see the effects of flicker at several hundred hertz. The ability to observe flicker varies greatly between individuals, and even depends on where a user is looking since peripheral vision is most sensitive.

100-120Hz flickering of fluorescent lights has in fact been linked to symptoms such as severe eye strain and headaches in a portion of the population, which is why high-frequency ballast circuits were developed that provide almost continuous output. Using PWM at low frequencies negates the advantages of using these better ballasts in backlights because it turns an almost constant light source back into one that flickers. An additional consideration is that poor quality or defective ballasts in fluorescent backlights can produce audible noise. In many cases this is exacerbated when PWM is introduced since the electronics are now dealing with an additional frequency at which power usage is changing.

It is also important to distinguish the difference between flicker in CRT displays and CCFL and LED backlit TFT displays. While a CRT may flicker as low as 60Hz, only a small strip is illuminated at any time as the electron gun scans from top to bottom. With CCFL and LED backlit TFT displays the entire screen surface illuminates at once, meaning much more light is emitted over a short time. This can be more distracting than in CRTs in some cases, especially if short duty cycles are used.

As we said at the beginning, this article is not designed to scare people away from modern LCD displays, rather to help inform people of this potential issue. With the growing popularity in W-LED backlit monitors it does seem to be causing more user complaints than older displays, and this is related to the PWM technique used and ultimately the type of backlight selected. Of course the problems which can potentially be caused by the use of PWM are not seen by everyone, and in fact I expect there are far more people who would never notice any of the symptoms than there are people who do. For those who do suffer from side effects including headaches and eye strain there is an explanation at least.

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.

LED monitors, on the other hand, can be the better option with general eye fatigue related to prolonged use and blue light, as they tend to offer a more robust dimming system.

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.

Once control moves to the next line of pixels, the brightness of the previous line of pixels fades. To fix this and provide an even light for the human eye, more power is required to increase the brightness when the pixels are refreshed.

LCDs can independently control each pixel, but not the brightness of that pixel. The brightness is control by the LED backlight that sits behind all the pixels.

OLEDs offer a much wider viewing angle than TFTS and LCDs (Liquid Crystal Displays). LCDs (FSTN) can provide up to a 120-degree viewing angle, but there will be a viewing bias. That is, one of the four views (top, bottom, left or right) will have the sharpest viewing angle.

LCDs do not glow and without a backlight they can operate on as little as 1mA. The addition of a LED backlight is necessary for nighttime operation but will increase current by 15mA to 90mA depending on the number of LEDs and how brightly they are driven.

If you need a very bright, multi-color graphics display, TFTs may be your best option since they can be modified to produce brightness in excess of 1K Nits.

Dark mode is where OLEDs can turn off individual pixels to save power. This is one key power saving advantage that OLEDs have over LCDs (Liquid Crystal Displays). LCDs are not able to turn off an independent pixel.

Portable health monitoring equipment such as Fitbit and smartwatches, mp3 players. VR headsets make use of OLEDs as they may reduce eye strain, last longer per charge and are thinner than TFTs.

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.

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 flicke
