Eye strain from screen

I have purchased a refurbished mac and I seem to be getting a great deal of eye strain. I have tried 2 different lcd monitors, reduced glare, tried the mac in different rooms, reset PRAM, re-sat the graphics card, recuded the brightness, calibrated the display settings and I'm still having problems.
I've taken the mac to the apple store genius bar and at first glance they didn't notice any problems, they said they could take it in for further inspection but I didn't really have the time.
I have have never had a problem like this with a pc or mac ever so I'm convinced its the graphics card, anything else anyone can suggest?

Fair enough.
Do you know specifically what is causing the strain or what it is that is unsettling about the image? Is it possible that the image is zoomed? Command-option-8 zooms the image in and then back out again.
Do you have font smoothing turned on?

I need honest oppinions on EYE STRAIN FROM IPAD

hello ,
I am planning to get an Ipad and I would use it lots to read.
Please tell me if you suffer from eyestrain, and also how long u read on it.
If you had KINDLE or other e-ink reader , tell me which one you think is better.
I appreciate all oppinions!
many thx
Anteros

I can't comment on a Kindle hardware device but I am surprised to find that the iPad works well for me as a reader. I expected to miss holding a physical book and was concerned about eye strain. I find I must turn the screen brightness down quite a lot - particularly at night. You can do this directly in iBooks but I haven't yet found a way to do it in the Kindle app. WIth the brightness way down, it doesn't seem to strain my eyes.
The iPad's glossy screen can be a bit of a nuisance outside in the sun.
The Kindle store has loads more titles in it than iBooks but the shopping experience feels disjointed in comparison because you are sent out of the Kindle app to the website. Great thing about the iPad is that you can run both
As others have commented, the multipurpose nature of the iPad makes it a winner for me when compared to a fixed function reader.

Eye Strain from Macbook Pro (2012) Anti-Glare?

Hi everyone,
I am thinking about buying my mother a macbook pro. She has been using macbook (2007) until today, so it will be a great gift.
Her eyes are not that good and can get motion sick easily (if that matters...), so I would like to know if any one had noticed eye strains, headach, etc from anti-glare version of macbook pro. I heard regular and glossy displays have possibility of causing such symptoms so those are out of options. So anti-glare or retina? Retina version is more than what she needs but I heard retina display could be better than anti-glare for someone. I am willing to pay retina version if anti-glare display causes eye strains while retina display does not. I would like to hear some experiences, thoughts, and advices. Taking her to store and test those displays would be best, but I would like to avoid it, since I want this to be a surprise gift. However, If I had to take her to store, how should I test which display is good for her?
Thank you very much!

I can only tell you my experience after having used the anti-glare screen for over 5 years. I can sit in front of my laptop for hours without any adverse effects. I passed on the retina Macbook Pro because it seems like an abomination not to offer such a beautiful screen in anti-glare format. The retina is less glossy than the regular screen, but nowhere close to the anti-glare in comfort (for me, at least).
I would check with her doctor, too. It may actually be that a screen with a smaller native resolution is better for her.

Eyes hurt from screen, changed from kdemod to xfce4

Ok this might sound stupid but yesterday I cahnged from kdemod to xfce4 and my eyes hurt after browsing the screen for a while. First I thought it had to do with my screen flickering or smoething but then someone told me lcd screens don't flicker. I installed the cairo-ubuntu freetype-ubuntu package etc but It didn't do any diffrance. Heres a screenshot. http://i43.tinypic.com/f3s3tx.jpg

Any remedy for eye strain using macbook pro retina?

since purchasing a macbook pro retina display around 33 weeks ago I'm getting major eye strain from using it and I'm not talking excessively,only an hour or two at a time,trying reducing the brightness but still no better,anybody else had success with this problem?as i know others have had same issue

Thinkpad 8 tablet - eye strain

I just got the Lenovo Thinkpad Tablet 8, and everytime I use it, in less then a few minutes I would get eye strains. I would get this "crawling" headache inside my head, I don't know how to describe it, feel a bit like burning feeling inside my eyes/head. Even when I stopped looking at the screen, it would take a few minutes for the eye strain to disappear. Its not painful, just that it is definitely eye strain and causing me a lot of discomfort. And this really frustrates me because I love this tablet. Here are some background about me and eye strains. Ever since the display technology shifted from CCFL's LCD to LED backlight, I started to get eye strains whenever I looked at certain (LED backlit) laptops, tablets and even smartphones. I first discovered the problem when I replaced my old CCFL LCD display laptop with a new LED-backlit display (Lenovo T420s). Using the Lenovo in just a few minutes I get eye strains and headache. After researching online and experimenting with mobile phone camera, I discovered that the cause of the eye strain is PWM, and putting the brightness to 100% eliminates the flickering, thus no more eye strain. But I had to reduce the contrast to artificially reduce the brightness so that I can use the laptop without blinding me. So I know that I am affected by PWM, and any display that uses PWM causes eye strain for me. But at least I know how to detect it (by using cell phone camera), and I can do something about it (set brightness to 100% to eliminate the PWM flicker). I did the camera test to detect PWM flickering on the Thinkpad 8 as described in this website: http://www.flatpanelshd.com/focus.php?subaction=showfull&id=1362457985 and the Thinkpad 8 does not seem to have PWM (i tested it at 50% brightness). So if the Thinkpad 8 tablet do not have PWM, yet when I use them, why do I still get eye strain? This is what puzzles me. Are there other causes of eye strain apart from PWM? I dont know if this would help, but here are some background on the type of devices that cause and don't cause eye strains to me: I have no problems with these displays and can use them for hours and hours:CRT monitorsAny CCFL LCDs monitorsBlackberry 9700, 9900, iPad 2iPad miniAny Super LCD2/LCD3 display (e.g. HTC One, HTC Desire etc)But if I look at the following LED-backlit displays even for a few minutes, I get eye strains, and have this "crawling" headache inside my head:Lenovo T420s laptop (if brightness less than 100%)Lenovo Thinkpad Tablet 8 (any brightness)Any Samsung's Super Amoled smartphones (e.g. S3, S4 etc, at any brightness, even 100%)So now I am trying to find if the Lenovo Thinkpad 8 dispay has some other "features" that causes eye strain, and see if there is something that can be done to solve / work around it (like the 100% brightness thing). I've been reading online about causes of eye strains, and this is what I have gathered as potential causes of eye strains: Brightness - glare from screen too bright (natural cause and effect)Looking at the screen too long (eye fatigue (natural cause and effect)PWM flickering - setting brightness to 100% can solve this problemBlue light - can use software like f.lux to make the colour temperature to be warmerThose are the main ones. But I have also read the following also can cause eye strain: Aggressive / excessive IPS AG coating FRC ditheringFor IPS AG coating, how to detect if the AG coating is "good" or "bad"? I looked at my Lenovo Thinkpad 8, and I have no idea what to look for, let alone what to do about it. Same goes for FRC dithering. Could someone explain to me what it is, how it is used, how to detect it and what can I do if my display has this? Or does anyone knows other potential causes of eye strains? And by the way, anybody else suffering from eye strains when using the Thinkpad 8?

It is likely the low PWM that you are suffering from or it might be the subpixel structure of particular panel. AMOLED displays use PenTile matrix that has issue with text readability .Unfortunately current mass production focused on cutting costs in favour of weak technical quality does not give you many options There might be also various revisions of the same LCD panel that have worse brigthness control regarding PWM control that others. Personally I understand you because I am very picky on choosing LCD monitor. It is a nightmare for me just to imagine I would have to spent at least one month again by trying to find shops where I can see the monitor under normal light conditions. There are too many aspects of LCD monitors that annoys me (flickering, screen door effect, too high lowest brightness, uneven backlight, blurry coating etc.) Another thing the might cause the eye strain is anti-aliasing blurry font rendering. I am unable to use it at all in any form (unless there are 1000 DPI or more desktop displays available) but turning it completely off in current software and OS is not easy. It is summarized in this article http://annystudio.com/misc/anti-aliased-fonts-hurt/ You may be right. It could still be PWM. Even though I tested with camera and cannot detect PWM (maybe I did the test wrong), the PWM might still be there but on higher frequency, which might be why it did not appear on camera, yet this PWM still causing me eye strain. It seems like there might more potential source of eye strains...anti-aliasing font. A screen could have a number of these elements that can cause eye strain causes. It is getting harder and harder for me to buy any electronics that uses LED backlit display. Recently I tried to look at some laptops, most of them, the screen gives me headache. Buying a laptop and even a tablet now is getting harder, for people who are sensitive to PWM like me. Sigh. You are also sensitive to PWM, right? And you get eye strain from LED backlit monitors too? Can you share what devices (smartphones, tablets, laptops etc) that you can use without a problem, and which ones are giving you eye strains. At least we can see if there is some patterns that can help us shed more light on this issue.

Logic 8 eye strain tiny fonts

Hi. I got my Logic 8 upgrade the other day. After using it for 2 hours my eyes look like someone punched me. Am I the only one to get eye strain from the tiny tiny fonts that apple has used? Is there anything I can do to remedy this? I can't see a way of changing the font size. Any one else have this problem?

Just finished a day of using logic and I have to say it is unuseable for me. My eyes are O.K. and I can use laptops all day without any problem, but I think the fonts in logic are so small it's just too much of a strain. I will have to go back to crap cubase 4 - reluctantly because it's completely unstable.

Eye strain - tiny little fonts!!!

Hi. I've been using logic 8 for a few hours today and I've already got eye strain from the tiny little fonts they have used. I have good eyesight and have been using my mac for days on end with no problems, but the size of the text in logic really does take the biscuit!! does anyone else have this problem?
Is there any way of changing in the font size? Any other workaround. I have never seen a programs with such ridiculously small text!!!

Glossy screens causes eye strain

Does any one knows if there are any studies published on reflective screens effect our vision when working long hours.
I'm using iMac 27" for about 1 year and I'm noticing my vision is going bad. I keep finding my self even today that I can't concentrate and I can't look at reflections that are allways there and chaning. Ambient light and in the evening light sources from the room constantly reflecting on my screen.
Can you share your expierence, working on a large glossy display and if you notice any side effects ?
Thank you

The iMac has a protective glass panel the covers the actual glass TFT screen.
It's the double panes of glass that cause some of the excessive glare on an iMac.
You maybe able to reduce the amount of glare by removing the glass and using one of these.
http://www.macframes.com/
The actual glass TFT screen of the iMac is still glossy,mbut with the extra panel of glass gone, it should reduce the glare to a much more tolerable level.
I use this, myself, and can work at my iMac longer and the headaches have, more or less, gone away, and I have noticed less eye strain.

Eye Strain induced by LED screens

I am an eye doctor in australia and have encountered an unusual amount of computer induced eye strain. What have others done to try and minimise this problem?
There seems to be a big issue with the intense light of LED screens. Has anyone tried one of the new Benq no flicker screens in reading mode?

I was having a lot of problems with my iMac and could only work on it for very short periods without my eyes hurting. It got to the point where I was going to sell it. I changed the colour temperature in Display settings from 6500 to 5250. The picture looked a bit yellow at first, but I soon got used to it and it is now very much better.
One possible explanation is that white LEDs have a very different spectrum to normal white light (e.g daylight). They are usually made by coating a blue LED with a phosphor that converts some of the blue light to yellow. The combination looks white but the spectrum has an enormous spike in the blue. It is possible that this is more tiring for our eyes.
The spectrum is shown in this article:
http://en.wikipedia.org/wiki/Light-emitting_diode#Phosphor-based_LEDs
I can't detect any flicker with the iMac screen. One way to test for flicker is to wave your hand rapidly in front of the screen. You get a "strobe" effect if it is flickering. Another way is to look at the screen through a digital camera (e.g. iPhone). Any flicker will tend to show up as stripes.

Is the MacBook Pro Retina display resolution of 2880-by-1800 a strain on the eyes as I understand the higher the resolution the more strainful the screen can be to the eyes?

Well there are two or three causes of eyestrain with displays different people seem to have.
1: Small type/UI elements
2: Glossy screens
3: Flicker rate
1:
The higher pixel rate combined with the display set at the higher resolution is going to cause UI and type to be smaller and harder to see. In fact it's advised to set OS X to a lower resolouton so it upscales better to match the pixel of the higher display.
Reports coming in say watching HD 1920 x 1080 trailers on the anti-glare 17" is best as the pixel content matches the display almost fullscreen, where on the MBP-R it's upscaled and thus looks blurry.
HD content makers are NOT going to change all their video cameras to support 2880 x 1800 full screen, so in order to get a clearer image playing HD 1080 content, one will have to do so in a smaller window.
2:
The new MBP-R dispalys are 75% less glossy, but not 100% less glossy like the anti-glare models so this can still cause some people problems. This can be lowered to under 1%, however I'm suspecting to do so would be considered giving up a military advantage to China where Apple gets it products made.
3:
I don't know about the flicker rate if it's better or not on the MBP-R's than the previous screens.

Eye strain= burning, red/bloodshop, itching eyes after working hours

I've been working on my macbook everyday for hours and have been experiencing significant eye strain. After a nights sleep, eyes are better. Yet, after working on the computer after a few hours....it comes back. This has never happened before and am wondering if it's the type of display/lighting.
I read some other posts and decided to try and calibrate. I changed the lighting to yellowish for graphic work.
Has anyone else noticed this problem. I thought it might be from the smaller 13" screen, which I've never used before. Always used a much bigger screen.
Any words of wisdom out there?

A small number of people do report having issues with the LED backlighting used in modern LCD displays. This is "believed" to be due to the way the LEDs are dimmed. LED dimming is actually simulated by blinking the LEDs on and off very quickly (as they can't actually dim in the truest sense). The frequency changes based on the dimmed level. With the display at full brightness, the LEDs are generally constantly "on". Some people believe the rapid flashing, even though not detectable, is causing the problem for them. You may want to try your display at full brightness to see if that helps. I haven't seen any significant research on the topic so pretty much everything is hearsay.

New macbook air eye strain

I used the 2010 model macbook pro 13 inch for the last two year...sometimes up to 12 hours a day with NO issues at all.
thursday I switched to a new macbook air 13 inch. Now I get horrible eye strain and a headache after 20-30 minutes.
Any ideas on what I can do to fix this? are the displays different?
If it doesn't get better i'll have to return the device. Its that bad!
Any help is MUCH appreciated

Hey jss. Well, same results at 1920x1200 as when the MBPr is in the retina display setting (1440x900). My vision gets blurry after working for a few hours when I look around at anything other then the laptop. It takes about 30 mins away from the computer to get my eyes to sort of refocus. And then left with a mild headache the rest of the day. So, I've decided to return it.
What is confusing to me is that if my eyes have a problem with the LED backlite and this screen tech has been in place since the overhaul in 2009 (???), why don't I have problems when working on my early 2011 17" MBP? Maybe its simply due to the 17" of space. After carrying around the MBPr, I don't want to return to lugging around this beast again. I'm going to check into the anti-glare 15.4 since I believe it uses different tech for the screen.
There are more threads on this subject in the forum, so it seems its something Apple should spend some time researching. It may not be a huge problem, but the number of people complaining about this problem seems to be on the rise.

Slightly misled & eye strain - Macbook Retina Display

Anyone else feel slightly misled over the new macbook "retina" display? Highest resolution ever in a laptop etc.
Well it isn't it's still basically the same 1440x900 desktop as my old macbook even if it is underpinned by 4 x the pixels.
If I deviate from the 1440 by upping the resolution to 1920 then the picture is not that sharp and I get eye strain.
I also run a Sony Vaio Z11 with a 1080p display (1920x1080) and that is on a 13" display and use that all day every day without problems.
Is it the off pitch resolution that is causing the problem, ie 1.5 pixels per desktop pixel thats causing the eye strain?

Unfortunately, the problem wasn't due to the glossy quality of the screen as I had purchased a hi-res anti-glare. I will probably put an anti-glare film on the retina display if I make the purchase, as I also find glossiness to be annoying. I do find it very interesting that you can use your matte LED screen for so long without trouble. I wish I could have said the same, but 15 minutes on my returned 2011 LED matte Pro left me with headaches and strained eyes. From reading the other large thread, it seems that some people are just more sensitive to the LED. Thanks for the response though!

Reducing Eye Strain for Constant Users ~

How does one correct for extreme eye strain and possible damage to the eyes and vision? Have tried the glasses with no success. Have searched the Apple site for glare screens and found none.
I am asking for my daughter who has a new Mac Tower, is in online school for web development, and is having extreme eye problems from extended time on the computer with a very large monitor. This is her profession and help is needed.
What is a "hood"? And would one help? Couldn't find anything for Mac. Does anyone know where we can find high quality glasses or glare screens? Has anyone had this problem and solved it successfully?
Thank you,
Cyan

One consideration may be the use of an overly-bright display affecting vision
over an extended period of time; years of staring into a computer screen may
add up to issues later on in life, if not more immediate discomfort/health issues.
While I have not bought them, there are static cling films and other products to
help protect the screen as well as eyes. One company I had contacted years
ago had been one of the innovators; and I still have a link to their site. It shows
protective film, hoods, and cleaning products. They used to offer custom sized
films to reduce glare as well as protect the soft-surfaced LCD panels, etc.
http://www.photodon.com/ - similar products have come and gone.
For some ultra-bright new flat panel screens, some users have opted to get & try
methods of dimming the panel further low, than the Brightness control could go.
A few third-party software tools are out there to add control for overly-bright LCDs.
There should be links to some solutions and maybe too many ads, via a search.
A few brightness control software items out there (free or share-ware) may darken
a display by a method which changes the colors of light and not by turning down
the actual brightness of the panel behind the LCD; so this may not be a longterm
answer if the display is also running brightly, and your color scheme is not correct.
http://www.charcoaldesign.co.uk/shades - they're out there; untested by me. ie:
