Hmmm, I'm starting to feel like the exception to the rule...

I am also over 30.  I've been working with CRTs at least part time since '78
and full time since '82.  I had progressive myopia before starting my career
with computers.

Over the span of my computer career, my rate of vision decline has slowed,
stopped, and even somewhat reversed itself.  My prescription is now back to
its '82 level.


Some things which I've been doing that *may* be helping: taking short breaks
from the CRT at least once per hour; taking a few seconds to focus on remote
objects in the room/lab every few minutes; sitting back from the CRT and using
a small font (my vision corrects to better than 20/20, so I take advantage of
the improvement!); and having a UV coating on my glasses.  Perhaps something
in that mix above is working to offset the problems of over-exposure to CRTs.

(Some of the above suggestions, BTW, came from watching a story on the impact
of VDUs [Visual Display Units] on journalists as on-line article composition
became more prevalent in that work environment -- advice from near the start
of my full-time career.  The "refocusing" suggestions were offered as a means
to avoid eye strain.)
