lcd screen eye strain quotation

I should mention that I did use the search function but couldn"t really find what i was looking for.

I have a hitachi superscan 753 19" monitor.
0.22h dot pitch
1600x1200 at 85
230 Mhz
31-107 KHz
50-160 Hz

I have a Matrox G450 Max dual head agp card and I run my desktop at
1280x1024.

I"m wondering what the best setting is to minimize eye strain. I noticed the refresh rate was at 60, when I changed it to 70 and 75, I started to see, i guess what you might call flicker (screen moving in a horizontal wave-like pattern).

I thought the higher the refresh rate, the better for the eyes? I"m not a gamer, i use it for mostly desktop/internet apps, media editing, watching movies and such.

Should I get an LCD monitor? I"m in front of my computer a lot and I do feel strain and fatigue (eye).

Oh, and about dot pitch, what"s the difference between just plain old dot pitch, AG or grille pitch. I"ve seen monitors that have a high grille pitch or AG pitch number be more expensive than say a similar monitor with a lower dot pitch number(horizontal)

There are a number of options for reducing digital eye strain and your exposure to blue light which include workspace ergonomics, computer glasses, specialized lenses and protective coatings. The first step is to get a comprehensive eye exam, making sure you speak to your eye doctor about how often you use a computer and digital device. This will help your doctor to get the full picture of your eye and vision needs in order to determine which option is best for you. It was also help the doctor to identify any underlying issues that could be worsening your symptoms.

Symptoms of computer or digital eyestrain tend to be noticed after someone has used a digital device for as little as 2 hours a day. Studies show that 60% of people spend more than 6 hours a day in front of a digital device and 70% of adults report some symptoms of computer vision syndrome (CVS) which include: Eyestrain

Digital eye strain also impacts your ability to focus and lessens productivity. Most people do nothing to ease their discomfort from these symptoms because they are not aware of the cause.

Proper Lighting and Screen Brightness: You want the screen to be as bright as the surrounding environment or the brightest object in the room (depending on what is most comfortable for you). Therefore interior lighting or sunlight from the outdoors should be dimmed or blocked. Use fewer light fixtures or lower voltage light bulbs and close curtains or blinds when possible. Adjust the brightness and contrast of your monitor to the levels that are most comfortable.

Reduce Glare: Glare is a significant cause of computer eyestrain so it is important to minimize it as much as possible. Set up your computer where glare from windows won’t affect your screen or cover windows when this is not possible. Glare can also reflect from walls and shiny finishes on desks and other surfaces. An anti-glare screen on your monitor or an anti-reflective (AR) or anti-glare coating applied to your eyewear can also help to minimize glare and the strain it causes to your vision.

Screen size and distance: You want to make sure you are using a high quality (such as a flat LCD) screen that has a relatively large display (look for a diagonal screen size of at least 19 inches) and is located directly in front of your line of vision. Your viewing distance should be about an arm’s length away with the top of the monitor at about eye level or slightly below.

Keep Eyes Moist:When viewing a digital screen or monitor for an extended period of time, we tend to blink less frequently (about ⅓ as often as we should). Blinking however, is critical for keeping the eyes moist, which allows them to remain clear and comfortable and to avoid dry eyes, irritation, blurry vision or eye fatigue.

Focus on blinking by setting a timer for every 20 minutes and slowly closing and opening your eyes 10 times. Keep a bottle of artificial tears handy to use when your eyes are feeling dry.

Give Your Eyes a Break: Schedule and take frequent breaks from your screen. Follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. Take this time to stand up and stretch your back, neck and legs as well.

Computer glasses reduce eye strain by adjusting the focus slightly so your eyes feel like they are focusing on something further away. They also have a tint to remove the glare and block blue light from entering into your eyes. There are a number of options for computer eyewear, both if you need prescription eyewear and not. Speak to your eye doctor about what the best options are for you.

It is important to know that both adults and children alike are susceptible to computer eye strain from computers and digital devices. With the growing use of such devices in our everyday lives it is important to start educating ourselves and our children on how to combat the negative effects of these habits.

The main problem I have with it however is the lighting. My laptop displayed everything fine at any brightness setting, and visibility was a matter of how the light in the area was. With this thing, any dark colours have no hope of being displayed as anything other than black to begin with, yet even if I pull the brightness far, far down, beyond the point where nothing is actually readable, it still gives off way more light than my laptop screen did, which (again, depending on the light in the room) didn"t seem like a light source at all.

I"ve been saving for a 120Hz monitor, but being a poor student my savings don"t increase too rapidly. I"m generally a patient person so I wouldn"t mind this too much, but this monitor (tv) is actually causing a significant amount of eye strain, even with all the tips concerning positioning, pauses etc, and using f.lux. After using it for an evening, the next day my eyes will look somewhat like this, if a bit less extreme. Though according to what I"ve found on the internet there is no scientific evidence this causes long-term damage, it still worries me, and aside from that it"s uncomfortable and just looks freaky.

My question to you would be if you"d recommend to keep saving for a 120Hz monitor, or to get a cheaper "normal" monitor for now. Or perhaps you have some incredible insight as to how to make this monitor not make my eyes resemble Voldemort"s.

The picture above is a screenshot of my monitor’s display. Below is one small portion of it. Look carefully at the New York Times article and compare it to what you see on your own monitor, here.

Furthermore, this 21.5″ 1920×1080 monitor is 34 inches from my eyes, so that I can’t distinguish individual pixels. The enlarged text appears very crisp from this distance, and this means easier reading and less eye fatigue.

Sit far from the monitor and increase screen font size to increase effective resolution. See “Reduce Eye Fatigue” section below for how to calculate this distance for your monitor.

Can a widescreen monitor be used effectively for the first two uses? Yes. Many people do. And it may be ideal in certain homes where the display is used for both entertainment and light work. But if you’re trying to work without distraction for hours at a time, you may find that a widescreen monitor will lead you down the dark path of multitasking unrelated activities.

I tried for two years to use a 24”, 1920×1200, widescreen monitor effectively at my office, because I often find myself flipping back and forth between writing and researching. I failed. With the combination of a widescreen monitor and a tabbed browser, I too often succumbed to multitasking unrelated activities.

I had other issues with the wide screen. The short monitor height required too many clicks to scroll through long articles. I couldn’t use fullscreen mode because text stretched super wide. And though tools like Readability or Readable could be used, much of the screen space was wasted with wide margins.

I did distracted myself with many experiments to try to improve the situation, including various utilities or plug-ins designed to manage large screens or block distraction. It turns out that most content is meant to be displayed vertically, and this is assumed in computer software and operating systems. I found myself constantly battling this vertical display assumption, and often losing. So after two years of reduced productivity I gave up on widescreen monitors.

Now I have the best of both worlds. I have a widescreen monitor, but it can pivot into a vertical position. It is in vertical position over 95% of the time.

Steve Jobs claims that you can’t distinguish individual pixels on a device with more than 300 PPI such as the iPhone 4 or iPod Touch 4g, which both have a 326 pixels per inch (PPI) “Retina Display.” He’s right. That is likely the main reason my eyes get less tired with this device than any other LCD display I’ve used.

Have you ever noticed how a massive HDTV looks great 6 or more feet away, but not so great close up? You can see the individual pixels on a 46” HDTV if you’re 3 feet away, but not if you’re 6 feet away. The same principal applies to an LCD display. Move it twice as far away, and you’ll only be able to distinguish half the detail.

In other words, you cannot distinguish individual pixels on a 326 PPI Retina Display that is more than 10.55 inches away from your eyes unless you have better than 20/20 vision. The same applies to my 103 PPI monitor at a distance of greater than 33.4 inches.

Enlarged text nearly three feet from my eyes is very easy to read. Another subtle benefit is that page elements such as tabs, menus, and status bars do not get larger. They look tiny relative to the enlarged text, so they’re less noticeable and less distracting.

Note that by enlarging your web pages or documents, you do end up with less information on the screen. I find that I don’t usually need 1920×1080 pixels worth of information on a screen at one time. But when I do, I can simply move the screen closer to my eyes. Yes I lose the benefits of having the equivalent of a Retina Display, but the trade-off is sometimes worthwhile, particularly with large spreadsheets.

On a vertical monitor, you have much more vertical space than on a horizontally positioned widescreen monitor. So you’ll need fewer clicks to scroll through the vertically arranged content, and you’ll be able to see more of it at a time.

For example, my Dell 21.5″, 1920×1080 monitor (HDTV resolution) can pivot between vertical and horizontal positions. The vertical position means 1920 pixels of vertical space devoted to a web page, while a horizontally positioned screen means only 1080 pixels of vertical space

You could theoretically get the same amount of text on the screen by filling up the entire monitor with your browser, but that stretches the text very wide. It is very difficult to read text which has 150 characters per line. Various studies show that people can read fastest at somewhere between 60 and 95 characters per line, which is what I get by positioning my monitor vertically, 34 inches away, with enlarged text.

The advantages of working using the cloud are numerous, but endless web distractions can lead to wasted time and feelings of information overload. I’ve discussed tools for reducing distraction for both writing and reading on the web. These tools work well on vertical monitors but poorly on widescreen monitors.

For example, the simplest distraction blocker is to simply put your browser into fullscreen mode by pressing the F11 key. Try it on a widescreen monitor and you’ll see your text stretches so wide that there’s more than 150 characters per line. This is difficult to read.

Fullscreen mode works as intended on a vertical monitor. You eliminate menus, toolbars, address bars, bookmark bars, and status bars. You also get more vertical space so you’ll display more of what you’re reading, leading to fewer clicks to read a long article.

My favorite distraction blockers these days are tools like Readability or Readable. Readability is built in to the Safari browser and it can be added to Firefox or Chrome with plugins. You can also use Readability or Readable bookmarklets on any browser. These tools do work on widescreen monitors as you can specify the text width, leaving wide margins. But using these tools on a vertical monitor is better because much more text is on the screen, which means less clicks when reading a long article.

Get a widescreen monitor that has the ability to pivot. Keep it in vertical position most of the time. Rotate it horizontally only when having more than one window open at a time will really help your productivity.

Inexpensive 19″, 1280×1024 monitors will do. But with 86 PPI, these monitors need to be 40” away to achieve the equivalent resolution of a Retina Display that is 10.55 inches from your eyes. Worse, you’ll need to enlarge the text in order to read it and then won’t be able to see much more information than you can on an iPod Touch. More likely is that you won’t want to position your 1280×1024 monitor so far away, so you’ll notice the individual pixels.

Luckily, high quality 1920×1080 monitors can be purchased for $150 to $400 these days. The diagonal length of monitors with this resolution ranges from 21.5” to 26”, but the larger sizes of these monitors usually cannot pivot. Furthermore, the bigger the monitor is, the farther you’ll need to place it away from your eyes.

The 21.5” diagonal screen size was the smallest I could find on a 1920×1080 monitor. It needs to be only 33.4” from my eyes (to achieve the same effect as a Retina Display at 10.55 inches), as opposed to the 37.5” required for a 24” display. Closer is better so I don’t have to lean forward as far when I need to look at something small.

Having failed to make good use of a widescreen monitor after two years of trying, I’ve obviously given up on them in the office. But many people use them for home entertainment purposes. And some people are very productive with them. Maybe you’re one of them, and you’d like to share about it below.

You don’t have to be incredibly tech-savvy to turn down the screen brightness on your laptop, but the process will vary depending on the model of your device. First, check the line of F keys on the top of your keyboard. If any of them have a little icon that looks like a light bulb, a sun, or any other light source, try pressing them to see if it adjusts brightness. Chances are that they, more likely than not, will do so. Keep in mind that you may need to use your Fn or Function key to trigger these effects.

If you want to lower your screen’s brightness for your desktop PC, there are a few ways to do so. Windows 10 makes it easy. Click the battery icon in your Windows 10 notification area, and adjust the brightness to suit your needs. To do so, open the Settings from the Start menu, select System, and choose Display. Adjust the slider to where you want your system’s brightness to be.

Windows 7 and 8.1 have a screen brightness adjuster in your system’s Control Panel. Select Hardware and Sound > Power Options. You’ll see the slider, which will be available at the bottom of the Power Plans window.

Windows 10 has the option to automatically adjust brightness in relation to your remaining battery life. To do so, open Settings > System > Battery save. Select Battery saver settings. You need to make sure that the Lower screen brightness while in battery saver is checked, and you can use the adjustable bar to select a percentage for when the screen will dim. By default, it will be set at 20 percent battery remaining.

While these tips will work on the software side of things, you can alter your monitor settings with the buttons on the side or front of the computer monitor. Most monitors have several different settings, including brightness, contrast, and color adjustments that you can tweak to make it easier on the eyes. We wish we could give you some specific tips for this, but virtually every monitor and manufacturer has slightly different configurations.

By keeping an eye on your screen’s brightness, you can keep your eyes healthy, experience less pain, and have longer battery life. For more great tips and tricks, subscribe to Info Advantage’s blog.

Interesting results but hard to put too much stock into it with a sample size of 10. I know a lot of people who have no difficulty reading on LCD screens and some who even prefer it. But I also know some who just can’t do it for long periods of time. 10 people doesn’t seem near enough to draw any conclusions.

LED and LCD display are good to addict people to use computer that’s reason why e-ink tecnology is not developped for using as screen for monitors. A lot of money is made on top of those addicting tecnologies! Light is addictive! That’s my opinion!

I agree, the study does not sound scientific at all. And e-ink is way less straining, obviously, without the need for scientific study – but the thing is it has been studied and e-ink is proven to be healthier.

Besides it is common sense, the eye is going to be much better if it is not getting flashed by a screen, e ink is obviously better for the eye there is no question there, you dont even need to do a study it is just common sense like saying you need a test to prove that watching the sun directly is not that bad for your eyes.

I don’t notice a different either way. I’ve never had a huge problem reading onscreen. Yes, reading of any kind for long hours (and I’m an avid reader so I do it for hours on end) tires my eyes. It dries them out. I can’t read white on black comfortably. But other than that, it doesn’t really matter to me if it’s e-ink, my computer or a paperback. Thankfully laptop screens are a lot better these days (resolution and whatnot) because I work on one all day.

I caved in last week and bought a tablet (a Nexus). Using the Kindle app on that, provided the illumination is right, is just as pleasant as using my Kindle 3, but here’s the thing — after an hour or two I mysteriously find myself wanting to swap them. There must be some subtle difference between the screens. It’s good that the subject is now coming under scientific scrutiny.

It’s diminishing, but before the rise of the tablets, whenever people thought about reading from a screen, they envisioned a monitor. And not a device which you could hold in your hand so you could find a comfortable position.

the screen size of the Droid Razr Max is 1.7 inches smaller than the Kindle’s, so it can fit less words of the same size. Over time, the Droid would tire the reader more.

Doesn’t look like they were comparing apples to apples. You’d have to have the same fonts, same font size, same size device, same resolution (or ability to range from the same to lower/higher resolutions), same lighting conditions, etc. and for good measure I’d throw in a couple scenarios – outdoor reading, indoor reading with adequate light and indoor reading with insufficient light. My take is that LCD reading has gotten much better with higher resolution screens and things like reading with black background/white text, but with screen glare, etc. e-ink is better in normal to bright light conditions. In my humble opini0n.

I say do the test again but strap the subjects into chairs and use an apparatus that forces their eyes open. Have violent and pornographic images pop up on the readers while classical music is playing. Then see what happens.

We believe that the "eye fatigue" found in previous studies may have been caused not by the LCD screen, but rather by the rabid wolverine clawing at the subjects eyeballs.

I always assumed that the eye fatigue caused by LCD screens was because people had the screen set too bright. When the screen is adjusted to the ambient lighting conditions I’ve never had a problem, but I see people reading LCD screens with the light so bright it would hurt my eyes. So perhaps in this test they set the brightness correctly, hence the difference with previous tests.

I always set my screen settings to lowest brightness, and reading on my LCD laptop screen still gives me tired eyes, and after a while slightly blurry vision and even spots for the eyes, plus it feels uncomfortable and makes me tired. I write, edit and read a lot on my laptop screen and these issues worry me and interfere with my productivity, so I am extremely eager to find a good quality e-ink monitor I can use with my laptop keyboard. A tablet screen is a bit too small but I would still prefer that if I could use it with my laptop keyboard, than looking at the LCD screen.

No colour or funky features are not a problem at all, but the refresh rate, font type, screen size etc needs to be convenient for writing and editing.

Anna, these are my thoughts exactly! I too have been longing for such a device: a laptop with an e-ink screen, or even a desktop computer with a e-ink monitor. Yes, black and white, yes, even with the less-than-stellar refresh rate!

There are so many professionals who would love to have this alternative to the LCD screen. Writers, academics in the humanities and sciences, editors, proofreaders, even accountants and architects — jobs in which one has to view a screen for hours. Jobs in which the colors on screen are unnecessary and where the refresh rate is irrelevant.

Someone should invent this screen and it would sell massively to publishing houses, newspaper editorial offices, universities… and individuals like myself.

Its cheap marketing tactic of f**king cheater companies, e-ink screens are really awesome and i never had eye strain on my kindle, while on lcd and led i got eye strain within minutes.

[…] New study suggests E-ink is NOT better for your eyes than LCDs (The Digital Reader/Nate Hoffelder) “The results from the visual fatigue query were fairly close, though the LCD did rate marginally higher. Even the reading speed was virtually identical. In fact, the only major difference was when the test subjects were queried about general fatigue. LCD test subjects reported a higher general fatigue level than did E-ink test subjects, but that could be due to the size and weight of the iPad. E-ink is often described as being just like reading on paper, and that’s why the scientists were surprised to discover that the results were so similar.” […]

If you work all day at a computer and have the serious related disorders (inability/delayed ability to focus at a distance, extreme light sensitivity) that can develop over time, then you know it’s the lighting that is to blame. You feel actual pain. You set the brightness as gently as you can while maintaining readibility, but it still hurts. There are eye exercises that help, and you learn to take breaks regularly. Setting a non-white background in applications that allow it helps (as it reduces brightness without affecting readibility). This study should have included people who actually suffer from this, as I do. Testing on people who don’t have the problem to begin with shows… no problem.

My eyes get tired in just a few seconds (!!!) after looking at any modern LCD screen of any technology (amoled, ips and so on). However, I can read an average paper for tens of hours without any problem. The difference is huge at least for me.

I read a lot, but I prefer physical books. I have just bought a Kindle Paperwhite and it deffo feels more comfortable on my eyes compared to all other devices.

"E-ink idiots" is the best word to describe them! making expensive devices for doing ONLY ONE task which they fail to do properly! i just get headaches more often because of E-Ink devices" flashing than lcds" brightness!

That is the best word to describe you..first of all you are deliberately insulting people without knowing what you are talking about, probably because you have never suffered of strong eyes disease like me….due to that, not only i invite you to read the comments here to understand that probably you are alone thinking in that way, but before insulting the others by calling them "idiots", look yourself at the mirror of your home….thanks to Eink my life has changed forever, finally, after years of eyes pains, i can read digital documents without burning out my eyes anymore….

This study is absurd. I have problems reading articles on an LCD screen. My eyes get really red and tired. However on my kindle I can read for hours at a time.

Changes always come with age. I am 58 years old working in Finance. I have to sit through layers and layers of figures in excel. Unfortunately my tired and aged eyes have not been accustomed well to years of staring at an LCD screen. I would think it might have been different if i were instead staring at figures and letters on paper rather than a bright TV-like source. It just doesn’t feel natural.

In my case, as I’ve gotten older, I’ve found that a LCD screen is easier to read than paper, under the right conditions. I read ebooks off my tablet in a fairly dim room with the brightness of the screen turned down. If I have to read from paper, I have to turn up the ambient light up enough to irritate my eyes. I haven’t tried an eink screen, but I assume it would give me the same trouble.

I sincerely doubt that you spend 10 hours reading on you LCD screen. There’s a lot of glancing away, looking at pictures and scrolling down the screen. It’s not the same as reading a book for hours at a time.

[…] can cause discomfort, whereas e-ink looks similar to paper and so will not cause eye strain. A recent study in Ophthalmic and Physiological Optics, however, questions all of this. Participants were asked to […]

If you read in closed spaces, in optimal conditions, then there might be no notable difference. But if the light sources around you are varying (as it happens in real life – in the bus, station, on the beach etc.), then the results are completely different, as the LCD doesn’t reflect the outer light and it’s unable to adjust its emitted light to compensate for the variations. This is where the e-ink has a huge advantage, because it reflects the outer light and you’re actually reading in the light of the environment.

It is a huge difference in reading inside an office or outside in the sun shine. If you try reading from a LCD in place where the light varies and shines from your back, then your eyes will put in a lot more effort than if you read from e-ink in the same conditions.

People saying "e ink idiots" are idiots themselves. Don’t you people understand that compared to LCD technology, e ink is still in its infancy? Think of all of the monochromatic LCD devices you owned before the technology had the ability to be used for displaying complex images. Think of the Timex watch you owned back in 82, think of the calculator you purchased back in 93. You catch my drift? E ink was only in the theoretical stages through the mid nineties. All of the extra years of R&D provided to LCD would give it the obvious advantage. But even more important than than that, the technologies are both so fundamentally different. LCD is the natural choice for moving images and such, whereas e ink excels in the static image department.

Furthermore, for the past 10 years, LCD has been nearly the only available display technology for so many different applications (think computers, TV, tablets, hell even NASA flight simulators). On the other hand, e ink has been relegated to a single market (e readers). How do you think that will affect the speed of development and improvement?

Perhaps, given enough time and demand, developers will be able to increase the resolution and refresh rate of e ink to the point where it can support color screens and maybe even motion (although, I would imagine that motion will remain out of e ink’s grasp due to inherent limitations).

This comment was written by a computer analyst who spends many hours of his day using LCD technology to perform his job. I am the owner of an LCD based smartphone, LCD based tablet and e ink based ereader. In my opininion, each technology currently serves its purpose well. If you’ve actually read this far, thank you for your time.

Indeed this study measures eyes strain on a very short period where everybody knows it takes years to damage eyes. Only a study lasting years could be significant here, would show how easy e-ink is for eyes after years not just a day or two !

There is also the weight factor. The kindle fire with the case is pretty heavy. The Kindle 2 (without the big leather case with the light) is much lighter. The glare off the screen was pretty bad too on sunny days. I would have to look for a seat away from a window or I couldn’t see anything.

The problem of LCD screen is more the biological effect that does stimulate people, viciate them to use computer and make them sleep later. This probably one of a big problem! The manufacturers really odes not want to see people stop to use computer. That’s why we see this kind of study that do forget the most imoortant part.

One of the wrongest thing i have ever read in internet in the last decade….i am the living proof that a eink screen has changed life of people with eyes problems forever….Before its invention, by using an lcd screen with whatever resolution you want, even fullHD, after half an hour my eyes WAS OUT!! now with a Eink screen i can read for 4 hours without stopping and without ANY sort of problems to my eyes……I can’t believe doctors and scientist are saying those idiot things….. I can show you with the help of my eyes doctor how both my eyes pressure and reddish color intensity change after i have spent 30 minutes in front of a even good LCD, and how they change in the same situation after 4 hours in front of a Eink screen……Finally thanks to Eink technology i am a man free to read all day long wikipedia articles! would you like to bet 1000 dollars that i am right and scientist are wrong? i am here with the money…write me an email and we will bet 1000 dollars…i am not joking….just come in Rome and i’ll present you my eyes doctor to prepare a test…..

Thanks for posting about this study; I looked up the article and read it. I would have been really interested in a comparison between e-ink, LCD, and paper, so I was sorry they didn’t include paper books as well. And it would have also been interesting if they had chosen an iPad with "retina" display; I would be curious to see what difference that made, if any. But I think for most people it’s probably just personal preference; they find a device that works for them and use it. For me, having gotten to the point where small print and dim lighting are problematic, I really like the larger screen (compared to the average e-ink reader), and adjustable font sizes on an iPad.

Despite the title of this post indicates that e-ink is not better than lcd, the article in which it is based only concluded that the lcd screens of nowadays are not that harmful as it used to be, and that can be assigned to improvements on resolution and bright levels of these new screens. What does not change is the fact that lcd screens emits light directly to the eyes, and this is harmful, even if it takes longer until you get tired of reading.

The E-ink makers have advertised their products as being better for your eyes without producing any evidence to back it up. I hardly see it as "attacking" them to mention a study that refutes their claims.

I think the whole thing is kind of pointless myself. Ambient light seems to have more to do with eyestrain than what type of screen you read. I’d guess that going out in the sunlight where I live causes a dozen times as much eyestrain than reading either LCD or E-ink in normal light. I get the least eyestrain reading white text off a black background in a dim room.

With 10 people, this is not a representative study, and as you pointed out yourself, the participants using LCD had more issues with fatigue, and if the "scientists" were so surprised, why didn’t they test with actual paper as well?

Also I doubt the tests they did were appropriate for the issue, they should have done a test with viewing abilities in the dark as well, as that’s where you can see significant decrease when using a screen with lighting.

Reading can be tiring even with paper, it’s not a very natural thing to do either, letters, reading and all that is very much a humanly constructed thing, while it should be significantly easier on the eyes with actual paper, it still will be tiring to your eyes, just like with displays and even more so if you have light coming directly from it.

I don’t buy it. I’ve used both. E-Ink readers are much easier on my eyes. And I currently own a Sony PRS-600 (that I found for $10) — this is one of the few "modern" E-Ink readers that has a highly reflective screen. Why was this particular model chosen? To skew the results? The Nook Simple Touch, one of the Kindles, one of the Kobos, or one of the newer Sony Readers would have made a better test subject. Even the Sony PRS-650 went to the Infared touch screen instead of the "shiny" screen of the 600.

excuse my English level, I live in Czech Republic, Pilsen (famous Pilsener Urquell beer), and I am a fan of music- el.guitar. I read for about one year Joe Pass’s "Blues for Basie" from my LCD’s PC monitor, and I could not remember almost anything- the feelings was strange – I knew all the music and but I could’t remember the notes. So I printed the notes on a paper, and I learned the whole song in 14 days by heart. I bought Kindle 5, using it everyday for studying songs, and I rememer it in same way like from paper, very fast. I don!t know how it is possible, but I am not able to remember anything from LCD’s, but from E Ink display I remember anything much easier.

The problem comes when companies (ignorant executives, middle management, arrogant designers) add things which subvert this clarity and contrast, thus destroying one of two primary advantages of e-ink. For instance, adding a touch screen layer often lowers the clarity of the underlying e-ink to the point that you might as well just use a traditional LCD. (Additionally, but unrelated, adding wireless and lighting which cannot be turned off, kill the other advantage, which is power savings, and the ability to not have to recharge for months, rather than weeks as in many current devices.)

Prior to commenting, people should make sure that what they are basing their experiences on is really e-ink, and whether or not that e-ink is beneath a poor quality touch screen layer. Go find an e-ink device that does not have a touch screen to be sure, and then you will see what e-ink really looks like.

The mass digitization of books is changing the way information is created, disseminated and displayed. Electronic book readers (e-readers) generally refer to two main display technologies: the electronic ink (E-ink) and the liquid crystal display (LCD). Both technologies have advantages and disadvantages, but the question whether one or the other triggers less visual fatigue is still open. The aim of the present research was to study the effects of the display technology on visual fatigue. To this end, participants performed a longitudinal study in which two last generation e-readers (LCD, E-ink) and paper book were tested in three different prolonged reading sessions separated by – on average – ten days. Results from both objective (Blinks per second) and subjective (Visual Fatigue Scale) measures suggested that reading on the LCD (Kindle Fire HD) triggers higher visual fatigue with respect to both the E-ink (Kindle Paperwhite) and the paper book. The absence of differences between E-ink and paper suggests that, concerning visual fatigue, the E-ink is indeed very similar to the paper.

this is not a study. this is a joke. 10 participants? and the higher level of fatigue from LCD might be due to the device being heavier?! come on, people, why do you even bother to publish such crap?

In 2018, AMOLED screen exposed a problem, that is, when the low brightness display, strobe will intensify eye fatigue, therefore, AMOLED screen is also known as the blind screen, of course, such a major problem soon got attention, after 2019, cell phone manufacturers have introduced hardware DC dimming, high-end flagship models are basically all popular DC dimming..

Hardware DC dimming solution is the way, the operating system directly output the screen to the display driver, the display driver to calculate the screen corresponding to the color, directly output to the screen, the step does not go through dither compensation, there is no loss of picture quality.

Therefore, the selection of AMOLED screen phone, the picture quality and more concerned about the students, pay a little attention to whether the hardware DC dimming support..

Almost all the flagship phones released use OLED screen, called AMOLED screen in Samsung, the essence is the same. As the OLED screen using PWM dimming mode, easy to “hurt the eyes”, LCD screen most of the use of DC dimming mode, there is no such problem. What is going on, and see the analysis below, what is the OLED screen, OLED screen using organic light-emitting materials, with self-emitting, wide viewing angle, infinitely high contrast, low energy consumption, very high response speed and other characteristics.

Power saving: OLED screen each pixel is working independently, if only part of the display content, the black part is not working; LCD screen as long as the content of a pixel is displayed, the backlight needs to be fully open; thickness: OLED screen without backlight board, color filter and other components, so the screen can be made thinner; flexible: OLED screen can be made into a flexible screen, the most typical case Is the iphone X using the chinless design.

OLED screen “hurt eyes” reason, OLED screen using PWM dimming mode, that is, the non-stop switch on and off the screen, in a cycle of open time on the high brightness, off the long time on the low brightness. If the frequency of the switch reaches a certain level, the naked eye is indistinguishable, the phone has been bright; according to IEEE documents point out that the flashing frequency of 3000Hz is harmless to the human eye, but Samsung, Apple and other cell phones OLED screen flashing frequency of only 250Hz, low-frequency flashing will cause eye pressure, migraines and other problems; when the lower the screen brightness, the strobe amount of rate will lower, more likely to cause eye damage.

Due to the inherent advantages of OLED screen, more and more manufacturers have been favored, with the maturity of OLED technology, cost reduction, there will be more and more cell phone screens using OLED screen, which is unavoidable; OLED screen low-frequency flicker is caused by “eye injury” of one aspect, other aspects such as screen The color is too bright, blue light is not handled well, the screen is too bright / too dark, etc. will cause some damage to the eyes; in the use of OLED screen, try not to use in a low-light environment, but also in order to save power to adjust the screen too dark, do not stare at the phone screen for a long time.

Protecting eyes from computer screens and smartphones is more important than ever, but effectively tackling the problem is more about prevention than treatment.

Simple preventative measures help protect eyes from computer screens and smartphones, and we’re going to take a look at a few of those measures in this article.

While not everyone spends every day looking at a computer screen, most people do use smartphones. Experts suggest that DES occurs in around 50% of computer users.

There is no evidence that strain makes your eyesight worse in the long run, but it does cause extreme discomfort and makes getting through a work day difficult.

How exactly does the screen affect your eyes? There are several signs to look out for, they can vary slightly depending on whether you use a computer or a smartphone. Let’s take a look at some of those complaints, and discuss how you can avoid them. The American Optometric Association recognizes the most common symptoms of eye strain are:Headaches

When looking at a high resolution screen, we subconsciously blink less, other pain responses can also decrease causing the body to not signal that something is wrong. This is particularly common with computer use and is called “computer vision syndrome”. Over long periods of time, this can be harmful to your overal eye health. When working on a computer all day, these symptoms can arise after using a screen for prolonged periods of time.

Your eyes aren’t designed to stare all day at something directly in front of you. With the 20/20/20 rule, you give your eyes a much-needed break during long work days.

If you look at the screen for 20 minutes, you must look at something at least 20 feet away from you for 20 seconds. The longer you look away from your screen, though, the better!

It may sound counterintuitive, but less light in your room is actually better for your eyes when you’re working on a computer. Offices shouldn’t be too bright, so when possible, close your curtains and reduce your use of fluorescent lighting.

Regular eye exams help to keep your eye health in check and ensure any problems you might be having aren’t anything other than normal eye strain. It also provides you an excellent opportunity to talk to an expert about your habits and eye health!

Use an anti-glare matte screen where possible (rather than glass-covered LCDs). If you’re a glasses wearer, make sure your lenses have an anti-reflective coating.

Most people don’t have to use CRT screens any more. Those are the old computer screens with low refresh rates that created a noticeable flicker that made your eyes feel uncomfortable.

Today, screens typically offer refresh rates of 75Hz or more. The higher the better. Furthermore, screens with higher resolutions appear more lifelike. When you can’t see the pixels, your eyes don’t work as hard to make sense of the images in front of you.

Blue light has a short wave-length and is known for causing damage to the eye. Reduce blue light by using specialist glasses or reduce the color temperature of your screen. It’s ideal for long-term use.

Just like computers, mobile phone screens can present an opportunity for eye strain. The fact we use our phones in place of pen and paper for virtually everything we do, means it’s something we should talk about. How do phones affect your eyes?

However, we often use our phones differently from our computers. With computer usage, we may spend several hours looking at the screen. We use smartphones for shorter periods of time throughout the day, but can total hours of usage by the end of the day.

Although this is less stressful for the eyes, if you’re straining when you look at your cellphone screen, it can mean you are placing stress on your eyes resulting in mobile phone eye strain. This can negatively affect your eye health over the long term.

It’s easy to forget that your screen can be customized, because it looks fine straight out of the box! Everyone’s eyes are different, however, and all smartphones allow you to change contrast, brightness, and text settings.

You should be able to see everything on your phone screen from between 16 and 18 inches away. Don’t hold your phone too close, but if you find yourself bringing the phone closer, consider zooming in on your screen instead.

Modern Android and Apple smartphones offer night mode features that make it easy to automatically reduce strain on your eyes at night.Turn the feature on, and your phone will automatically adjust screen settings depending on the time of day.

Smartphone screens are glossy, but matte screen protectors give you that old-screen LCD finish. They protect your screen and they reduce glare from ambient lights or sunshine. They’re inexpensive, too!

For all types of eyestrain, be it caused by computers or mobile devices, artificial tears can be an effective tool in keeping the eyes comfortably lubricated. There are many types of lubricating eye drops on the market — both with and without preservatives — that can be purchased over the counter. You may need to try several before you find the one you like best.

Adjusting the brightness on your phone is important, your phone may even do it automatically. The ambient light sensor on your device will allow the light to shift depending on how much light is already available. As mentioned earlier, the night mode feature reduces the impact blue light has on your eyes.

Still, struggling? Don’t fret. At the Kraff Eye Institute in Chicago, we have some of the country’s leading eye specialists who can diagnose concerns, offer excellent treatment plans and care, and help make sure your eye health is the best it can be.

A study supported by the NIH found that some pre-teens who clocked over seven hours a day on screens had differences in parts of their brains compared to kids who spent less time on screens.

It"s 11:00 pm. You should be asleep. But you"re watching a video on your phone. Tomorrow, you"ll wake up and go to work, where you"ll stare at your computer for 8 hours. When you get home, you"ll watch a movie on TV. And if you"re anything like the average American adult, you spend more than 7 hours a day staring at digital screens.

So, what"s all this screen time actually doing to your body and brain? Humans didn"t evolve to stare at bright screens all day. And our eyes are suffering the consequences. An estimated 58% of people who work on computers experience what"s called Computer Vision Syndrome.

And long-term, this amount of screen time could be damaging our vision permanently. Since 1971, cases of nearsightedness in the US have nearly doubled, which some scientists partly link to increased screen time. And in Asia today, nearly 90 percent of teens and adults are nearsighted. But it"s not just the brightness of our screens that affects us.

It"s also the color. Screens emit a mix of red, green, and blue light — similar colors in sunlight. And over millennia, it was blue wavelengths in sunlight that helped us keep our circadian rhythms in sync with our environment. But since our circadian rhythms are more sensitive to blue light than any others,

A problem occurs when we use our screens at night. Typically, when the sun sets, we produce the hormone melatonin. This hormone regulates our circadian rhythms, helping us feel tired and fall asleep. But many studies have found that blue light from screens can disrupt this process.

But perhaps the most concerning changes we"re starting to see from all this screen time is in kids" brains. An ongoing study supported by the NIH has found that some pre-teens who clocked over 7 hours a day on screens had differences in a part of their brains called the cortex. That"s the region responsible for processing information from our five senses.

Usually, our cortex gets thinner as we mature. But these kids had thinner cortices earlier than other kids who spent less time on screens. Scientists aren"t sure what this could mean for how the kids learn and behave later in life. But the same data also showed that kids who spent more than 2 hours a day on screens scored lower on thinking and language skill tests.

To be clear, the NIH data can"t confirm if more time spent staring at screens causes these effects. But they"ll have a better idea of any links as they continue to follow and study these kids over the next decade. It"s no doubt that screens have changed the way we communicate. But only time will tell what other changes are on the horizon for humankind.

You may have seen news stories about possible vision damage from the blue light emitted by computers, smartphones, tablets, televisions, and other electronic devices. Too much screen time is a common pitfall in this digital age, and it can cause eyestrain in some people. But the chances of permanent vision damage are low.

About 80% of American adults say they use digital devices for more than two hours per day, and nearly 67% use two or more devices at the same time. This level of exposure to digital technology for work, school, entertainment, and everyday activities has created a set of symptoms known as digital eyestrain (DES). Nearly 60%of Americans experience some symptoms of DES.

This has led to health concerns about the potential for blue light to harm eye tissue. Because blue light has a short wavelength, it produces a high amount of energy. Dozens of studies have investigated whether exposure to blue light over time could cause serious, long-term eye damage.

Early laboratory research using animal models suggested that excessive blue light exposure could damage some sensitive cells in the retina, the layer of nerve cells behind the eyeball. It can lead to eyestrain and focusing problems, but no research has conclusively shown that blue light causes long-term harm, eye disease, or retina damage.

Despite this lack of proof, many news sources, health- and vision-related websites, and health organizations suggest a causal link between blue light exposure and retina damage. This has led to an interest in “blue blockers,” which are special eyeglass lenses that filter out blue light in the same way UV lenses block ultraviolet light.

Manufacturers of these lenses often make bold claims about using blue blockers to prevent retina damage, sometimes quoting studies that examined the effect of blue light on cellular eye tissue. However, a National Institutes of Health analysis of blue blockers research found no solid evidence that these lenses improve vision or preserve retina health.

Still, too much time with digital devices can cause problems. Digital eyestrain often leads to dry eyes and puts an extra burden on the muscles that help the eye focus. Also, the eyes do not blink as frequently when looking at digital devices, which causes faster disruption and evaporation of the film of tears that protects the surface of the eye. That can cause minor eye irritations such as burning and stinging.

Eye soreness, ranging from stabbing pain to a gritty/sandy feeling, can often be caused by staring at bright screens for too long. Phones and computers deservedly

When it comes down to it, staring at your TV in a dark room is like someone shining a flashlight in your eyes. You want to blink and turn away, but naturally you can"t. The whole point of that bright light is to stare at it! It"s also perfectly normal to want to watch TV in a dark room. Cinemas are dark for several reasons, but related to this topic it"s for better immersion into the movie. The same goes for the TV at home.

However, if you"re watching TV in a dark room, which we highly recommend for any high-quality video experience, those sizzling highlights may seem too bright, causing your eyes to become sore or scratchy. If you"ve ever stared at your phone in a dark room, you"ve probably experienced this.

Someone shining a flashlight in your eyes at night is annoying, right? But standing in a room with the lights on isn"t. Your eye adjusts to the average amount of light hitting your retina. A dark room with a bright TV is still, on average, dark. So your iris is wide open. But the parts of your retina getting hit by the light from the TV are overwhelmed. They get fatigued, causing the tired, scratchy feeling.

A small, bright object in a dark room confuses your eye. The "average" amount of light is low, your irises open up, and the bright "pinpoint" of light strains part of your retinas. A larger TV, or sitting closer to your current TV, will fill a greater percentage of your field of view. With more of your eye filled with light, your irises will contract, so less light overall is hitting your retinas. Generally this will mean less eye fatigue.

Turning a light on is another option, but of course, this can create reflections (or worse, be a distraction in your eyeline). Again, you may not care about either of these two drawbacks, but I"m hoping to help you find the most perfect solution for your setup.

Ideal lamp placement is somewhere not in your eyeline to the TV, and not somewhere it causes a reflection. This might have to be somewhere out of the ordinary, like behind a sofa.

The point is, adding more light to the room raises the "average" amount of light in the room, making your irises close a bit, letting less light in, and potentially causing less eye fatigue.

One step further than a lamp is a bias light. These neutral-white lights add a bit of light to the room, they don"t negatively impact the image on the TV, and they reduce eye strain.

The color is important because whatever color the lights are, that color is "subtracted" by your brain from the color you see on screen. So if you have a blue light behind the TV, the TV will look red. The right color for bias lights is a neutral white; as close to the D6500 color temperature standard as possible.

TVs have long been far brighter than necessary for the average room. HDR does potentially make the problem worse, since they are, on the whole, much brighter than older, "SDR" TVs. If you experience eyestrain with HDR or other material, hopefully our fixes can help. If they don"t, and you"ve tried similar fixes with your other bright devices, it"s worth talking to an eye doctor to make sure there"s nothing else going on.

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.

Have you ever been on a train and had the sun shine on your book from behind you making it hard to read or on your smartphone screen creating a glare and making it hard to see?

When you"re working on your PC, similar poor conditions may develop without you realizing it. For example, if the lights are near the center of the room, and your PC is set up with you facing the wall, although the level of brightness is different, you could experience something similar to sunlight shining on your screen from behind you like on the train. If that"s the case, consider changing the layout.

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. S
