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.

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.

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.

Here"s another reason to curb screen time: a problem called computer vision syndrome — an umbrella term for conditions that result from looking at a computer or smartphone screen. "It"s most prevalent with computers, and typically occurs when looking at a screen at arm"s length or closer," says Dr. Matthew Gardiner, an ophthalmologist with Harvard-affiliated Massachusetts Eye and Ear Infirmary.

One is dry eyes, caused by a lack of blinking. "When you look at a screen, you"re so involved that you forget to blink. The blink rate goes from 15 times a minute to five or seven times per minute," explains Dr. Gardiner. But you need to blink to re-establish the tear film on the eyes — a thin layer of liquid that protects the surface of the eye. If you don"t blink enough, your eyes dry out, causing blurry vision and discomfort.

The other main problem from staring at a screen too long is eyestrain. Dr. Gardiner says one possible cause of this is the brightness or glare that comes from the electronic screen. "Bright light sources can feel uncomfortable, especially if you have cataracts," Dr. Gardiner says. Eyestrain can also result from focusing up close on a screen without the proper eyeglass prescription. "Any time you strain to see something, maybe because you need reading glasses and have resisted getting them, you can get a headache. You can exhaust your eyes" ability to focus," says Dr. Gardiner.

Some research has even suggested that eyestrain may result from difficulty focusing on the text and images on computer screens in particular, since they"re made of pixels that create blurry edges.

Fortunately, eyestrain and dry eyes are easily treated. Dr. Gardiner recommends using artificial tears several times throughout the day. The artificial tears don"t have to be preservative-free. Another tip: remind yourself to blink from time to time.

If you have eyestrain and headaches after looking at the computer screen for long periods, make sure your eyeglass prescription is up to date. "The proper glasses can reduce eyestrain," says Dr. Gardiner. "The classic example is a person who never needed glasses, and then after age 45 has trouble seeing up close and is straining all day and getting headaches. Once the person gets reading glasses, the headaches are gone."

Mom warned you not to sit too close to the TV when you were a kid. "In the past, screens were bombarded with energy. That emission back in the 1950s was too strong. In the "60s and "70s, they made safer TVs. Now with LCD or LED TVs, there"s nothing coming out of the screen to hurt you," says Dr. Matthew Gardiner, an ophthalmologist with Harvard-affiliated Massachusetts Eye and Ear Infirmary.

Watching TV for long periods won"t generally lead to computer vision syndrome, since you"re using your distance vision for viewing, not close-up vision, which risks eyestrain. However, sitting too close to a big-screen TV may cause neck strain. "You"ll only see what"s right in front of you, and end up looking around to see all aspects of the screen," says Dr. Gardiner.

Blue light has gotten a bad rap, getting blamed for loss of sleep and eye damage. Personal electronic devices emit more blue light than any other color. Blue light has a short wavelength, which means that it is high-energy and can damage the delicate tissues of the eye. It can also pass through the eye to the retina, the collection of neurons that converts light into the signals that are the foundation of sight.

As an assistant professor at The Ohio State University College of Optometry, I teach and conduct vision research, including work with retinal eye cells. I also see patients in the college’s teaching clinics. Often, my patients want to know how they can keep their eyes healthy despite looking at a computer screen all day. They often ask about “blue-blocking” spectacle lenses that they see advertised on the internet.

Human eyes are different than rodent eyes. We have protective elements, such as macular pigments and the natural blue-blocking ability of the crystalline lens. These structures absorb blue light before it reaches the delicate retina.

That doesn’t mean you should throw away those sunglasses; they provide benefits beyond protecting your eyes from the Sun’s blue light. For example, wearing sunglasses slows down the development of cataracts, which cloud vision.

Just because blue light isn’t harming your retina doesn’t mean your electronic devices are harmless, or that blue light doesn’t affect your eyes. Because of its wavelength, blue light does disrupt healthy sleep physiology. Blue-light-sensitive cells, known as known as intrinsically photosensitive retinal ganglion cells, or ipRGCs, play a key role here, because they tell the brain’s master clock how light it is in the environment. That means, when you look at a brightly lit screen, these cells help set your internal clock for daytime-level alertness.

As for your tired eyes after a long day spent staring at your computer – another common complaint I hear from my patients – blue light isn’t solely to blame for that, either. A recent study demonstrated that cutting blue light alone did not improve people’s reported comfort after a long computer session any more than simply dimming the screen.

Mounting evidence suggests that, compared to reading a paperback, screen time before bed increases the time it takes to fall asleep. It also robs you of restorative rapid-eye-movement sleep, dulls focus and diminishes brain activity the next day. Holding your phone close to your eyes with the lights on likely exacerbates the problem.

As for eye strain, ensure that you have the appropriate glasses or contact lens prescription. Only an optometrist or ophthalmologist can give you this information.

You also need to take care of the surface of your eyes. We don’t just look at our computer screens, we stare at them. In fact, our blink rate plummets from about 12 blinks a minute to six. As a result, tears evaporate off the eyes, and they don’t accumulate again until we step away from the screen and start blinking. This causes inflammation on the eye’s surface. That’s why your eyes feel dry and tired after a day spent at the computer. I counsel my patients to take two steps to ensure that their eyes stay moist during long computer sessions.

First, follow the “20-20-20” rule. The American Optometric Association defines this rule as taking a 20-second break every 20 minutes to look at something 20 feet in the distance. This will allow your eyes to blink and relax. There are many apps available to help remind you to follow this rule.

Second, use a lubricating eye drop before extended computer use. This tactic will reinforce the body’s natural tears and keep the eye’s surface hydrated. But, avoid those “get-the-red-out” drops. They contain drugs that cause long-term redness and preservatives that may damage the outer layers of the eye. I have found that artificial tears labeled “preservative free” often work best.

Based on my research, my advice is don’t believe the hype about blue light and don’t waste your money on products you don’t need. Instead, keep screens out of your bedroom and dim them before bedtime and keep your eyes lubricated. And don’t forget to blink!

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 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 flicker-free and blue light reduction, the Samsung Odyssey G7 Series 32-Inch WQHD ties everything together in a stunning package that’s nearly out of this world and is a monitor you can buy and be set for the future with.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Using a laptop is not without its problems as there can be side effects such as eye strain. Due to this side effect, there have been several questions as to which laptop screen can reduce eye strain.

To be frank, there is no specific laptop screen which can reduce eye strain.Instead, what you can look out for in the process of purchasing a system is the components of the laptop screen.

Purchasing a laptop without doing proper research on the screen properties can lead to constant eye strain. However, this does not mean you cannot find a way around it. With the following tips, you can reduce the level of discomfort on your eyes during the use of your PC.

The way your body is positioned during the use of a laptop can lead to eye strain. According to an articleby the American Occupational Safety and Health Association, the placement of the laptop and the posture of the body can affect the eyes.

Instead of slouching your body or craning your neck use the laptop, using a table or stack of books to raise the screen to the eye reduces the strain. On the other hand, if you have a chair that is lower than the desk, change it for another one that you can increase its height.

Tweaking the settings of your PC is another way to guard against eye strain. Sometimes, the brightness or contrast level of your system can be set too high or too low. Changing them to the optimum setting should help if not totally alleviate the problem.

Glare from the laptop screen can irritate the eyes and also affect your mood. If the light is cast directly at the eyes, it will cause eye strain. Therefore, to prevent it, either purchase a laptop with pre-installed anti-glare or place anti-reflective protectors over the screen.

The constant flicker of the lights can lead to eye strain. The duration of this flicker is called the refresh rate. A laptop with a high refresh rate is able to diminish the flickers.

In laptops, the most common panel to find is LCD. LCD is an acronym for liquid crystal display. More often than not, you will see an LCD panel with LED (light-emitting diode) which is a different method of backlighting a PC.

Yes, the screen resolution of a laptop can affect the eyes. This is mostly common when the display screen of the laptop is quite small thereby affecting the alignment of the display with the eye level. Therefore, when possible always opt for a laptop with a larger resolution.

Staring at your laptop screen for long intervals can lead to eye strain. This side effect is easily avoidable if you put in place preventive measures such as the use of anti-glare goggles and screen protectors.
