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.

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.

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.

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!

Keep yourself protected while working long hours staring at your computer monitors as they are built with strong LED bulbs that give off blue light that could be harmful to your eye health in the long run. To prevent extended daily exposure to blue light, you can now add a shield for your safety with blue light filters for computer screens that will effectively block out the harmful blue light to protect eyes. A blue light filter is a thin film that you can apply on the screen as an extra layer for protection and will prevent any damage to your eyes due to exposure.

Digital screens have become an integral part of our lives today and they are there everywhere. The only way to shield yourself and minimize contact is to take protective measures, and the best way to do it is to get yourself a blue light filter screen protector. Give your eyes relief from pain, burning, or any strain, and enjoy your screen time worry-free! You will no longer have headaches after a long day at work or face blurry vision, or eye strain, if you install monitors blue light filters.

American Optometric Association (AOA) defines CVS or digital eye strain as a group of eye and vision-related problems that results from prolonged usage of computers, tablets, e-readers, and cell phones which causes increased stress to near vision in particlular.

The symptoms reported in children with a prolonged history of screen exposure include reduced attention span, poor behaviour, irritability, dry eyes, ocular irritation, eye strain, headache, neck pain and shoulder pain.

Reduced blinking: Though the normal blinking rate is around 15-20 /min, the blinking rate is significantly reduced while working on VDT. This causes the eye to be opened for a longer duration and thereby increases the chances of dryness.

Evaluation of a patient with CVS can be performed using objective or subjective methods. Associated Dry eye disease should be evaluated as denoted in the eyewiki articles available at https://eyewiki.aao.org/Dry_Eye_Syndrome and https://eyewiki.aao.org/Dry_eye_diagnosis_and_management.

Computer work and work that needs concentration are known to reduce the blinking rate and thereby increase the exposure time of ocular surface and dry eye.

To reduce eye strain, the room lighting may be adjusted and the contrast of the computer screen may be increased. Matte screen filter can be considered.

Individuals who work for a prolonged period at computer screens, should take breaks and remember to blink frequently during work to reduce the CVS symptoms. This relaxes and restores the accommodative system reducing digital eye strain. According to the famous 20-20-20 rule, every 20 minutes, an individual should take the eye off from the screen for about 20 seconds and look at a distant object (situated at 20 feet away).

Environmental factors that can aggaravate dry eye symptoms include low ambient humidity, air conditioners, and ventillation fans. Modifications to improve humidity and ergonomic design of the workplace should be planned to reduce dry eye as mentioned under ergonomics.

Lubricating drops may reduce dry eye symptoms including dryness, irritation, ocular discomfort, tiredness and difficulty in focusing though complete resolution may not occur.

Blinking exercises every 20 minutes by closing the eyes for 2 seconds, opening and again closing for 2 seconds followed by squeezing for 2 seconds showed positive effect on alleviating dry eye symptoms and signs.

Polyvinyl alcohol, dextran and polyvinyl pyrrolidine have been found to be effective for evaporative dry eyes but with less evidence. Lubricants ranging from carboxymethyl cellulose to highly viscous topical drops and ointments reduce the symptoms of dry eye but do not increase the blink rate.

Omega 3 fatty acids were shown to improve dry eye symptoms and Nelson grade in CVS-related dry eye. Freedom from symptoms was reported in 70% cases in a study by Bhargava and colleagues.

According to the American Academy of Ophthalmology "There is no scientific evidence that the light coming from computer screens is damaging to the eyes. Because of this, the Academy does not recommend any special eye wear for computer use."

Such glasses may increase the humidity and reduce evaporation of tear film thus reducing the dry eye symptoms. It may also protect from particulate matters/irritants in the air.

If you’re always surrounded by displays—PCs, smartphones and tablets—are you placing too much strain on your eyes, neck and shoulders? If this sounds like you, read this article and take steps to address it right away before your symptoms worsen.

Information technology has made our lives more convenient, but at the same time, eye fatigue caused by continuous viewing of displays has increasingly become a social problem. If you feel fatigue in your eyes, neck or shoulders, it"s important to properly address it rather than letting it go. If you let it go and your symptoms worsen, you could damage your mental and physical health, so be careful.

Some of the names for the various problems associated with displays and eyes are "computer vision syndrome," "VDT (visual display terminal) syndrome" and "technostress ophthalmopathy." They"re unavoidable problems when it comes to PC work in particular. There are various ways to address the problems, and the effects vary from person to person, but if you try one at a time, you"ll undoubtedly be able to experience a more pleasant digital life. It will also contribute to improved productivity in the office.

We"ve put together a list of 10 points about measures to address eye fatigue. We recommend checking the items that catch your eye first and then going back to the start and reading through all of them.

What can further worsen your eye fatigue in a situation like this is the light reflected from your display. Shiny glare panels are made to provide accurate blacks and colorful display, so they are good for watching videos, but they also tend to reflect outside light. In an office or similar setting, lights and other displays can be reflected on your screen, throwing off your focus and causing eye fatigue.

For regular PC work, an LCD with a non-glare panel that does not reflect light is easier to use. If the product you"re currently using has a glare panel, you can affix low-reflection film to the screen.

Fluorescent lights are brightly reflected on the glare panel, making the screen hard to see. These conditions can easily strain your eyes (left). A non-glare panel can substantially reduce the reflection of fluorescent lights and reduce the strain on your eyes (right). The difference is as plain as day.

It’s also important not to make the lights in the room too bright. It"s common for advice to focus on not letting the room be too dark, but if the lights are too bright, it creates a difference between the screen brightness and ambient light, and that"s also no good. More specific details on screen brightness are provided in Point 5. Also pay attention to the temperature setting on your air conditioner and the direction in which it blows. These things can cause dry eyes, and your seat should never be positioned so that the air conditioner is blowing directly in your face.

Generally speaking, the distance between the user and the screen should be at least 40 centimeters or 50 centimeters in the case of a wide screen. The reason you should be further away from a wide screen is that the wider screen will not fit completely into your field of vision unless you sit further back. The conditions will vary slightly depending on other factors as well, including screen resolution, text size and your eyesight.

No matter what the situation, if you are viewing a screen at a distance of less than 30 centimeters for long periods of time, your eyes are obviously going to become fatigued. If you have an A4-sized sheet of paper, hold it up longways between you and the screen on which this article is displayed and see if there is enough room for it to fit. An A4-sized sheet of paper is about 30 centimeters (297 millimeters) long, so if you"re viewing the screen from a shorter distance than this, you"re too close. If you"re viewing it at a distance of about 1.5 times that length, you"re safe for now.

Once you"re at the proper distance from the display, try to have it so that your line of sight is directly ahead or slightly downward when viewing the screen. You should avoid looking up at the screen, because that can cause dry eye.

Your posture sitting in your chair is also important. Sit back in the chair, sit up straight using the back rest, and keep the bottom of your feet completely on the floor. This eliminates extra strain on your neck, shoulders and lower back. Sitting hunchbacked can lead to health problems in the long run, so you need to exercise caution. If your feet don"t reach the floor, consider using a footrest.

The adjustment mechanism of the LCD is also important for working on a PC in a posture that does not strain the eyes, neck and shoulders. Choose a product that allows the screen to be lowered just above the table top and flexible tilt adjustments (photograph: EIZO"s FlexScan EV2436W.

Even if the installation location of the display and your posture during use is proper, working in the same posture for extended periods of time is not good for your eyes. The reason is that constantly looking at something at a fixed distance causes a gradual decline in your eyes" ability to focus.

Take a 10-15 minute break at least once an hour. Look into the distance and move your eyes up, down, left and right to adjust your focus. It"s also good to regularly use eye drops.

A common mistake people make is looking at smartphone and tablet displays during their break. This does not allow your eyes to rest. Stretch to relieve tension, stand up and walk around, and look near and far either indoors or outdoors to adjust the focus of your eyes.

The suggestions up to this point have been predicated on the assumption that you have sufficient eyesight or that you use glasses or contact lens to properly correct your eyesight.

Eyesight changes gradually during daily life activities. Even if you wear glasses or contact lenses, if you stay at the same prescription for many years, your eyesight will change without you realizing it, and this could cause eye fatigue or migraine headaches. Using eye drops and adjusting the focus of your eyes during breaks does not help this problem.

Where you get in trouble is your eyesight doesn"t change suddenly one day, so even if you have symptoms like eye fatigue and headaches, it"s hard to identify the cause. If you let it go, it could lead to glaucoma and other worsening symptoms, so you should have your eyes checked at least once a year, which may be included in your company or school health examinations. Be vigilant about checking to make sure your prescription is not off.

The brightness of your display should not be left at the default setting but adjusted according to the brightness of the room where it"s installed. This can greatly reduce the strain on your eyes. For example, in an office with normal brightness of 300-500 lux, the display brightness should be adjusted to around 100-150 cd/m2.

Particularly, when using the display for work, you"ll often be comparing paper documents with documents on the screen, so by adjusting the brightness of the screen to the brightness of the paper under the lighting, you"ll reduce the strain on your eyes, making this an effective measure against eye fatigue.

The majority of LCDs today have LED backlights. In some cases, the brightness adjustment mechanism (dimming system) causes eye fatigue. Specifically, caution is required with the system called PWM (Pulse Modulation), which is employed by most displays. In this system, the LED element blinking time is adjusted to control the display brightness — extending the time that it"s on makes it brighter, and extending the time that it"s off makes it darker.

For some people, this blinking of the screen is experienced as flickering, leading to eye fatigue. There is a difference among individuals in how this flickering is experienced. Many people using the same display will not notice anything at all, so even in an office where the same model is purchased in bulk, it"s difficult to figure out that the display is the cause.

The only way to prevent this is to address it with the display itself. Some displays prevent flickering by employing special dimming systems such as DC (Direct Current), a system that, in principle, does not produce flickering, and EyeCare Dimming, a hybrid system used in some EIZO products. By purchasing a product like this, you may eliminate eye fatigue for which the cause was unknown.

We"d like to add a note about the EyeCare dimming system. This hybrid system uses DC dimming at high brightness settings and PWM dimming at low brightness settings as it does a better job than DC dimming at reproducing colors at low brightness. PWM dimming is only used at low brightness settings, so the blinking luminance difference is smaller, thereby controlling flickering.

If you feel like your eye fatigue has worsened since starting to use your current display, this could be the cause. If you"re in an office, switching out displays with another member of the staff is another effective way to identify the cause.

EIZO"s FlexScan EV series employs the unique EyeCare Dimming system. We put a small USB fan in front of the screen to check for flickering. At high brightness, DC dimming is used, and the light emitting elements do not blink, so the shape of the blades appears circular (left). At low brightness, PWM dimming is used, and the blades appear separate from each other, so you can see that high-speed blinking that can"t be perceived is taking place (right).

Recently, it has become common to hear blue light pointed out as a cause of eye fatigue. This refers to light that is visible to humans (visible light) with a wavelength close to that of ultraviolet rays. Because it has a high level of energy, it is generally said to place a strain on the eyes.

The reason it has recently been the subject of attention is that there are many LCD products with LED backlights that have a high color temperature display (white appears bluish), and there are more cases where the user is subjected to stronger blue light than with conventional displays, so this type of problem has come under closer scrutiny.

Some methods to address the problem are to wear blue light blocking glasses or to apply blue light reducing film to the LCD screen. Also remember that on products that allow the display picture quality to be adjusted, you can lower the color temperature on the display.

For example, results of an experiment (results of EIZO study) show that if you change the 6,500-7,000K color temperature used in common displays to 5,000K, the 400-500nm wavelengths corresponding to blue light can be cut by about 20%. Furthermore, by adjusting the screen brightness to a proper level that does not cause eye fatigue, you can reduce blue light by a total of 60-70%. Many of the aforementioned blue light blocking glasses only cut up to 50% of blue light, so this is more effective.

It"s a little painful to hear, but in many cases, changing your lifestyle habits is a fundamental way that you can address eye fatigue. If you have poor lifestyle habits that can bring about poor physical health like lack of sleep, lack of exercise or nutritional deficiency from poor eating habits, take this opportunity to re-examine them.

If you"ve taken the above steps and your eye fatigue has not gotten better or there are signs that it"s getting worse, you should consider undergoing an examination by an ophthalmologist. Not only will you receive expert advice on your symptoms but it may also lead to early detection of inconceivable eye diseases like the aforementioned glaucoma.

As you can see from the points we"ve already gone over, if you really want to address eye fatigue, you obviously have to put in effort yourself, but your choice of display is another important point. No matter how much you as the user address eye fatigue, if your display does not meet certain quality standards, the effectiveness of your efforts will be limited.

If you"ve checked off items 1-9 but your eye fatigue has remained unchanged for a long period of time, you may want to turn your attention to the display itself.

For example, EIZO"s FlexScan EV series of LCDs places emphasis on addressing eye fatigue and has features to address points 1 (installation environment), 2 (posture during use), 3 (proper rest), 5 (brightness), 6 (flickering) and 7 (blue light) above.

The FlexScan EV series requires almost no cumbersome manual adjustments, offering the major advantage of automating features that address eye fatigue. If you"re someone who knows the tricks to addressing eye fatigue but are finding them difficult to implement due to being busy, we recommend that you seriously consider the FlexScan EV series.

In Paper mode, the color and contrast display is similar to paper. With this excellent feature, the color temperature is lowered instantly with the touch of a button, and blue light is substantially reduced (left). If you use the Auto EcoView function, the built-in illuminance sensor detects ambient brightness and automatically takes the display brightness down to the optimal level in real time (right). The aforementioned EyeCare Dimming system suppresses flickering of the screen display at the same time.

Paper mode display features color and contrast similar to paper. EyeCare Filter software applies filter pattern that controls brightness and contrast.

We"ve looked at various measures to address eye fatigue, but in cases where the user is required to remember to do them daily as they work, particularly when busy, people tend to neglect them. Moreover, when people make the effort to do these individual things to address eye fatigue but then don"t get much of a benefit due to the quality of the display, it"s really a waste if you think about it. Purchasing a replacement display requires an adequate expenditure, so people tend to hesitate, but if you"re purchasing a product that has excellent basic performance, eliminates the need for cumbersome manual settings and automatically lessens eye fatigue, isn"t it worth it?

The value of considering replacing the display itself is significant as a trump card for addressing eye fatigue. At home, it will help protect your eyes and the eyes of your loved ones, and at the office where you sit in front of the screen for long hours, it"s sure to contribute to greater efficiency and an improved working environment.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Screen time is even higher for people whose jobs necessitate looking at a computer monitor for all of their work. An ergonomic desk chair can alleviate some physical strain, but it’s the monitor itself that can help — or hurt — the most.

A monitor that’s not designed with your well-being in mind can cause eye strain, migraines and even muscular problems in your back and neck. Naturally, these effects lead to reduced productivity, absenteeism and general job dissatisfaction. But more strikingly, computer blue light is linked to blurred vision, dry eyes, macular degeneration and cataracts. It can even cause significant sleep issues.

It’s possible to mitigate these effects by switching to a monitor with built-in eye protection. Samsung has made eye care a priority in developing a number of unique display technologies, including a blue light filter for its monitors and Flicker Free technology.

Samsung’s latest high-resolution monitors feature Eye Saver Mode, which actively reduces blue-light emissions. This feature minimizes immediate eye strain and helps prevent longer-terms problems like phototoxicity, a condition of particularly high light sensitivity in the eyes or skin.

The best monitors for eye health address more than just blue light. Another culprit of eye strain and headaches is screen flicker — common on many desktop monitors, and nearly imperceptible to the naked eye. This flicker is a result of the screen’s backlight rapidly turning on and off. You may not notice it happening, but you will notice its effects. Samsung’s Flicker Free technology helps remedy this.

A high monitor refresh rate — the amount of times the screen updates per second — can help reduce eye strain, but above 75Hz, the difference on the eyes is minimal.

Together, these Intelligent Eye Care features have earned Samsung’s high-resolution monitors an Intelligent Eye Care certification from the gold-standard TUV Rheinland.

Besides the screen itself, your desktop’s physical aspects also contribute to its overall comfort. Samsung monitors’ ergonomic design offer height adjustment as well as tilt and swivel flexibility, so sitting in front of the computer is much less taxing on not just your eyes but also your neck and spine.

In the right environment, a curved screen offers considerable eye health benefits. You might even opt for a double-wide curved screen, like Samsung’s 49-inch S95UA. With a screen that imitates the curvature of the human eye, these displays mimic your natural field of vision — so your eyes don’t have to work as hard to focus.

Of course, not everyone’s workstation can accommodate a curved monitor, and not every job requires one. For smaller workstations, Samsung’s compact 24-inch T45F monitor comes with all the same protective eye health features. The monitor’s borderless design also makes the screen more immersive, to help keep distractions to a minimum.

With Samsung’s extensive range of high-resolution monitors, you can get the job done more comfortably — with eye-saving display features that let you put your health first.

When using a computer for prolonged periods of time, whether for work or pleasure, it"s important to protect your eyes from long-term damage. The following sections provide ways you can protect your eyes and reduce eyestrain.

Keep the monitor about 20 to 30-inches away (usually around arm length) from your face. This range is best for proper viewing and reducing strain on your eyes.

Adjust the height of the monitor or chair so the top of the monitor is slightly below your eye level. You should be looking slightly down when viewing the screen.

We recommend using an LCD or LED flat-panel monitor for your computer. The older CRT monitors are harder on the eyes due to the lower refresh rates and general design of the monitor. LCD and LED monitors feature higher refresh rates, high enough that most people cannot see the refreshing of the screen. LCD and LED monitors in general are easier to view for longer periods of time and cause less strain on the eyes.

Today, LCD and LED monitors are very affordable. You can get a 24-inch monitor for as low as $100, and a 27-inch for as low as $150. Curved LED monitors can reduce eye strain by providing a better viewing range, but at a much higher price point.

Some companies, like 3M, offer accessories for computers that help protect your eyes and increase your productivity at home or at work. Below are two of the popular computer accessories you can try.

One of the most important things you can do to protect your eyes is to take regular breaks. Taking several minutes to get up and not look at the computer screen can greatly help in reducing any strain and tiredness of your eyes.

A common recommendation from doctors and specialists is to take a five-minute break every hour of computer use. For that five minutes, you can get up and walk around, get something to drink, or do exercises to help increase blood flow in your body and your brain. These actions allow your eyes to rest for a few minutes.

Increased or long-term exposure to blue light causes eye strain and makes it more difficult to get to sleep at night. By reducing or eliminating the output of blue light on your computer screen, you can reduce strain on your eyes.

Finally, it"s important to also realize that there are health-related conditions like CVS (computer vision syndrome) due to prolonged computer use. If you continue to have eye issues after following all of the steps on this page, we recommend seeing an eye doctor.

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.
