>shape of the lens of the eye is a function of three sets of muscles that can be trained/relaxed to help vision come back to 'normal'.

Didn't read your link but could this explain why programmers get poor eyesite as they frequently focus on close objects (monitors) and thus the three sets of muscles become accustom to focusing on close objects?

My eye doctor certainly thinks that's a contributing factor. His recommendation (for me) was that after every hour (or 55 minutes) of PC work, I should spend five minutes looking at things at distance (buildings, trees, etc). It's probably frowned upon by my employers (as I don't have a window office), but it's helped reduce my eye strain quite a bit.

Too bad for them. Your eyes are more important.

I agree. Which is why I'm not overly concerned with what they think about the subject. ;) My supervisor seemed content with "doctor's recommendation" once when I mentioned it to him.
I was recently diagnosed with a condition called Keratoconus... from wikipedia:

Keratoconus (from Greek: kerato- horn, cornea; and konos cone), is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve.

Although my doctor said it was not caused by 10+hrs/day in front of a computer, i suspect otherwise. Its a relatively rare condition, and at my current office there are three of us (out of 25) with the condition.

I would like to know, dear HN readers, do you have this condition?

Definitely. Intact the most important paper on eyesight (IMHO) concludes that the way to guard against myopia is to spend more time outdoors where most objects in your vision will be far away. I'll find the link when I'm not on this stupid iPad!
i think the biggest problem with screens is that the eyes get dehydrated because we blink less often. certainly, the lens muscles may get overused as well though.
