Eye strain and monitor types

Hi folks,
first of all, i am a big fan of IBM/Lenovo T series thinkpads
Last week I bought a used T500 (22434EG) 15,4", 1280x800, and after using it for a few hours, i get eye strain and headache. My previoius machine was a T60 (1951FEG) with 15,1" 1024x768 and i could use it for days without any issues. I works in IT business, so i spend a lot of time with my computer.
Are there any further infos about these two monitors? I would like to compare them to identify what type of monitor/notebook sholud i buy, that fits my eyes. (I read a lot of PWM, LCD displays, LED/CCFL backlits)
The T500 monitor type is LEN4050, connector type: LVDS, device type: LFP, gamma : 2,2
I dont have any info about the T60, because i dont have it anymore. (I am working on it to get it back.)
Thanks,
Gellert
Solved!
Go to Solution.

Just suggesting if you have not already done so.
Increase color dept to 32bit? or reduce to 16 bit?
Increase refresh rate to 60Hz? or reduce to 50Hz?

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Terrible eye strain and vision problems

HP recently gave me a replacement to a Pavillion w/ Windows 7.
The brand new twice as expensive laptop had 8.1
For two weeks the screen was hazy, they replace the monitor, then sent me a new computer.
It too was hazy although less. After 2 weeks my eyes hurt so bad, I returned it and kept my old 7.1 which is quite clear and sharp.
My eyes are having serious issues, I always had 20x20. Now there is strain in my eyes and my vision is hampered.
I want to sue.......
What can I do?????? Where to begin????
I even went to Best Buy and looked at 3 HP's two of them were completely hazed the $1000 one was clear.
But all were 8.1. This is a serious problem.

What can I do?????? Where to begin????
Look up the specifications for your particular computer model's display. Specifically, find out what the "native" screen resolution
is. All LCDs have a "native" or "for best results" or "recommended" resolution. It will be expressed in pixels (e.g., something like "1366 x 768 pixels").
Now, with the computer on and showing the desktop, right-click in an open space on the desktop and choose
Screen Resolution.
Does the displayed Resolution: value you see there match your native screen resolution?
If not, and you change it to make it match, then OK out of the dialog, does it look better?

White Balance - Eye Dropper and Monitor Calibration

Does the eye dropper correctly set the white point even if the monitor is not correctly calibrated? I do calibrate monthly with the XRite but I'm not sure that the calibration is perfect.
I use a grey card, and the eye dropper in LR. So even though I calibrate - must the monitor be correctly calibrated for the eye dropper to work?
... and now tell me what monitor you love for photo editing. Thanks

Thanks for this answer,
I am using a Dell LCD monitor and have been happy with the color, but can not get skin tones right in my prints, they look washed out after I do a grey card white balance. So I just ordered a Eizo CG222WBK, now I'll only have myself to blame if my images don't look right

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.

Eye strain on Mac Pro late 2013

Hi guys,
I Have a problem with my Mac Pro late 2013. After few hours of work my eyes start to hurt really badly, my head hurts also. I am working on Dell U2713HM, few days ago I changed it for a pair of u2312 Dell monitors and I feel the eye strain again. When I try to work on my Asus laptop using the same monitor I don't have a problem. I tryed all the advices on the web for eye strain regarding monitor configuration but it has no effect. Also i can see the image on the monitor isn't rendering properly for example when I open an image there is always some square parts randomly missing.
Do I have a graphic card problem, monitor problem or something else.
Any experiences anybod, please help.

I agree I tried a little Google and came up with this site maybe something to look at https://discussion.evernote.com/topic/47161-mac-evernote-clip-rectangle-control- command-c-not-working/page-2 and there seems more have problems thoug not with Mac Pro MBP Retina: Poor image quality from hdmi output
and here http://forums.macrumors.com/showthread.php?t=1235305
Hope something of this will help. To me it seem that there is a communicate problems between Mac Pro and The monitor.

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:

Eye-strain & headaches

I’ve built a short animation in flash and converted it
to a screensaver using 3rd party software. We have deployed it
across our company as a method of carrying a corporate message, but
have had a complaint from an employee that it is causing him
eye-strain and headaches when he sees it “from the corner of
his eye”.
I know there are eye-strain issues with monitor refresh rates
lower than 65zz (?), and photosensitive epilepsy can be caused by a
flicker rate in the 16-25hz range, but are there possible clashes
between movie frame-rate and monitor refresh rates, or does anyone
have any information on this topic in general?
Any help much appreciated.

I'm not a neurologist, and no shrink either, so I'll stick to
the technical facts:
Iamgine the screen refresh-rate that way:
Your movie is running at the frame rate you have set, or as
near as the speed of your computer will allow. It is running on a
virtual screen inside your computer, the refresh-rate is acting
like a shutter in front of a window throuh which you look inside
the computer. The inner screen doesn't care about the outer
shutter. So I wouldn't see any clashes.
The corner of the eye is in fact the most sensive part of our
field of vison concerning movement; should have ben usefull for
detecting lions asap for our ancestors ;-)
I don't know what your animation looks like, but I don't
supose it is a problem of your animation. It might just be that the
employee in question never had anything moving before on his screen
that captuerd his/her attention when having the screen at the
corner of his/her field of vision.
So if on the monitor we are talking about is at a low screen
rate (I personally can't stand refreshrates under 85 per sec in the
corner of the I) and is senstitve to that in a way - that might be
an explanation. If so I would try to increase the refreh-rate if
possible with the hardware.
Propably the person in question just wants a new and shiny
flats-creen display - nothing wrong in that ;-)

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.

IOS 7 eye strain

The new iOS 7 is causing me eye strain. The font hurts my eyes. I can live with the "juvenille" icons but the sharp lines,and contrast or lack of is killing my eyes! Besides "brightness" and font size is there anything I can do to to help with this terrible download? Apple, big mistake here! Please help.....

I get really bad eye strain and headaches with iOS 7. None of the accessibility settings have helped.
Search twitter for 'ios 7 eyes hurt' and you'll see that a lot of people are suffering as well.
Please let Apple know this is an issue by calling 1-800-MY-IPHONE (1-800-694-7466) or sending a message at http://www.apple.com/feedback.

My eyes strain badly with the new iMac display - 2014

I recently bought a 2013 iMac 14.2 to replace my 2007 iMac 7.1.
I immediately noticed that my eyes were straining very badly in front of the new screen. No matter how I tweak the adjustments, I can't bear to look at the screen long enough to do any significant work.
Since I still have the old iMac in the same room, I can easily compare by just switching desks. With the old one, no problem. The moment I sit in front of the new screen, my eyes start aching and watering. It's not a question of contrast, brightness, or any adjustable parameters that I'm aware of.
I checked on the Net, and a significant number of other people report the same type of issues. I have not found any solution, nor any explanation.
I remember that in the days of the CRT monitors on PCs, I had to adjust the refresh rate as high as possible in order to avoid headache and eye strain. Anything 60Hz or below was unbearable.
Is there a similar issue with the LED backlighting?
Does anyone have an in-depth knowledge of the specificities of LED-backlit screens, such as wavelength, variation in light intensity/flickering/refresh rate, etc.?
There is a technical explanation and - hopefully - solution, and it's not "all in your head", "get glasses", "blink twice and stare at the opposite wall for one minute"...

Calibration affects the color, not the refresh rate, and I'm pretty sure that this is an issue of refresh rate.
Even though LED/LCD screens do not have the very noticeable flickering of a CRT when refreshing the image horizontally, there are still refresh frequencies used.
There is no direct access to these settings, and I wonder if there is a software out there that gives you access to the full display/GPU parameters.
My GPU is a NVIDIA GeForce GT 755M.
As I said earlier, there IS an issue here (other people are affected), and there IS a solution somewhere. Besides the fact that Apple should definitely look into it and come up with a permanent fix (like changing the default settings, or having a user-configurable display) I'm sure that users with the necessary knowledge will be able to work out a solution.

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.

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?

Eye strain again

Am I the only person getting eye strain off logic studio? The fonts used are literally half the size of those used on other apple programs and I've now got bloodshot eyes! I've been using cubase for years now with no problems, but I want to 'move over'
Anyway my question is this: Can I get a bigger monitor with the same number of pixels but bigger screen size, so that the text is larger? Is this possible?
Chris

Thanks for your comments everyone. Can I please ask EVERYONE who reads this thread to send a comment to apple via the feedback system mentioned previously to make the fonts BIGGER. If we all send them feedback, they may well listen.
As I have said, I've used cubase for years now and it is truly a crap piece of software, but effectively I cannot move over to logic because my eyes just can't take it. I refuse to get glasses just for one piece of software when every other program I use is fine.
If I just adjust the screen resolution or use the zoom function, it all goes blurry, which is even worse for my eyes. I will see if I can get a bigger monitor, but even that will make everything blurry. The only answer is BIGGER FONTS!!!!
I can't face going back to crapbase 4 with all it's crashes and bugs. What can I do?????

LCD display causes eye strain/headache/nausea

I have posted about this before a couple of years ago. And the thread went wild.....SO many people having trouble with various types of displays. I wanted to get back on the track for my particular display which is a 24" LCD -- ATI RADEON HD 2600 PRO 256MB GRAPHICS. A couple of years ago, I was only noticing eye strain after using it for a prolonged period of time. And if I didn't stop, then that eye strain could develop into a headache.
I have tried taking the brightness all the way down which helps somewhat. I try changing my chair position to make sure I am looking down towards the display and not up. I look away as often as possible to stop the focus on the display. It all helps.
BUT a couple of years have passed and I still am experiencing the same things....only it happens after 5 minutes of usage. And now I almost always get a headache, my eyes feel dry and almost hurt. My neck gets stiff -- perhaps from the expected strain I know will occur. And since a few months, I also notice a feeling of nausea as well -- like motion sickness. GOOD GRIEF is all I can say.
I love my iMac...... but have backed away from using it as I would like. And use my iPad most of the time now. It does not seem to cause me such problems. I know one of these days it will be time for a new mac as this one is nearly 5 years old. And I cannot say that I am keen at all to buy another iMac. Curious about all of you out there and what you are experiencing and could recommend to help alleviate the problems.
THANKS TO ALL!!!!!!!!!!

Yours is a genuine problem, and it will not be solved by changing the screen resolution which does not affect brightness or glare.
May I suggest you investigate getting an anti-glare screen filter? These are listed here on Amazon in the UK but I am sure that Amazon in the US (or whereever it is you live) would have them as well:

Anyone with eye strain problem after upgrading to Yosemite please report feedback to Apple

As this eye strain problem is getting worse and basically I love some new Yosemite features, so please let Apple knows if this new upgrade have some display problems. I am using iMac 27" late 2013. this eye strain problem doesn't occur when using Mavericks (my mac is dual boot Maverick <-> Yosemite)
https://www.apple.com/feedback/
Thanks in advance.

Perform the following, stopping with the first one which works:
1. Open the Mac App Store's Purchases tab. If you're prompted to accept it and the other iLife/iWork applications into your Apple ID, do so.
2. Move them out of the Applications folder(they may need to be put into the Trash temporarily), and then see if you can download them for free from their individual product pages. If you're asked to buy them, see #3.
3. Click here, contact Apple, and wait for a response.
4. Buy them.
