screen resolutions and eye strain

[Elizabeth L. Blakely]

I realize that you can fit more on a screen with 600 x 840 but worry about
corresponding problems with eyestrain.  I recently tried switching my
screen to a higher resolution and found the 600 x 840 really difficult to
adjust to.  Part of the problem seems to emanate from focusing on to fine
a subject for too long.  The experts all encourage us to take regular
breaks to alleviate potential problems of eyestrain, wrist strain, neck
problems--but how many of us do?  

Maybe this should be a focus of more research by our profession (in
conjunction with medical and human computer interaction types) in a
culture which is becoming increasingly dependent on computers.  Moreover
shouldn't we as professionals should be extremely careful about
exasterbating the problem.  Does using a high resolution limit access by
the visually impaired?
