I began working in a DBA position at only 30 years old with 20/20 eyesight and now 4 years later looking at the same computer screen I find myself using glasses! I never expected my vision would deteriorate due to being on the computer so much. It started as maybe an hour a day to now I am absorbing UV rays at least 8 hours a day from the screen. I did find out from a colleague of mine it is easier if I wear some kind of low power reading glasses. So that is exactly what I searched for, a pair that did not look awful and that would help me out in the long run. I found out quickly, I did not need a prescription and that there are some really cute pairs available on line if you look for them. I found 2 very nice ones and thankfully my eyes feel much better from using them.
