to the OP and anyone who has this problem I am another victim of eye strain, the first time I noticed was when I bought a samsung tv, I just couldn't stand it at first it took a month of watching the TV to finally get rid of the feeling and im talking it actually hurt while I was watching the tv. I went to an ophthalmologist very knowledgeable woman and she told me that the tv was only making the problem obvious, that I had a sensitivity to the display and that everyone is different in this sense it would be very hard to determine the exact cause of the problem and that if it persisted for a long time that I should return the tv and get one that didn't bother my eyes... long story short it was a year before I actually got a prescription glasses made, and now that I wear them often I can tell you that if I take them off to watch the TV I get that old eye strain feeling back from watching the TV..

anyway I would recommend going to an ophthalmologist and explaining the problem in detail, they might have a solution even if you have 20/20 vision there can be a lens configuration to help you not get the eye strain on the specific activity

Oh come on, people. This guy is just asking for help, and so many of you take the opportunity to make him feel like a freak. Eye strain is a very common problem because of monitors. I don't have any suggestions to help other than giving up your iMac. I wear eyeglasses that I had made just to reduce monitor eye strain. They definitely help, but your dissection of the monitor and your theory about the 1/4 inch space makes a lot of sense to me, and most likely won't be fixed with glasses. Good luck! And sorry about some of the other A holes on this thread.

Your eye strain is most likely caused by sensitivity to the LED backlight flicker. There is a short discussion and video where a MacBook Pro's flickering is slowed 40 times at this site, http://www.squidoo.com/led-backlight-flicker .

This thread is almost a year old, folks.

Did the OP eventually find a resolution to this?

His 1/4 inch space theory is a possibility, and does make some sense. When I first bought a 27" iMac with LED in Late 2009, I had a similar problem with what I considered was the brightness, and blue spectrum light... I turned down the brightness rather low, but the problem, eye strain, and headaches, persisted.

I talked to my ophthalmologist about whether he had heard anything about a problem like this, and he hadn't. I changed to another Dr., and he hadn't heard of anything about LED displays causing problems like this, either.


I did look into how LED displays differed from the florescent backlit displays. and eventually just sat back at least three feet, and left the screen dimmed, and enlarged the text. Eventually it didn't seem to bother me as much.

This may not bother too many people, but to those it does, it's a real issue.

THIS. My eyes are so, so much happier using my Asus V236H CCFL screen over my 2012 27" iMac. The eye-strain is killer for me on all LED-backlit display. Dealing with it is no fun...
