High Definition and Ocular Health

[Musashi]

What is currently known about the long term effects of high definition viewing on the health of your eyes? Particularly, I was curious how its effects differ (better/worse/=) from watching equivalent hours of standard def.

I also found this fairly intersting: http://www.swift.ac.uk/vision.pdf
It suggests that high definition pushes the upper limits of what human eyes can detect.

Edit: http://www.clarkvision.com/imagedeta...esolution.html This on the other hand suggests what I would think: that real life's equivalent pixel limit is much higher, even for a given screen size. It could be that the previous article is using retinal detection while the 2nd is citing full effect of 2 eyes+the brain working together.
