Weird request... but does anyone else take some form of stimulant or drug that dilates your pupils and work at a computer during the day? I've taken adderall and ritalin for ADHD and my eyes will actually be sore at the end of the day. It goes away by morning, but there's been times I just felt like shit at the end of the day and go home and sleep because I just can't stand any more light.
For OP's question... I don't think my eyes have degraded one bit, but I'm still in my 20s and I had 20/10 vision to start with.
I have been thinking this exact thing lately, having been off Ritalin for months and recently started taking it again. My eyes feel awful at the end of the workday, something I did not notice in the exact same work environment when I was off the medication.
Those pills can raise your blood-pressure, so maybe that's cause of your problem? Next time that happens, take your blood pressure and see if it's higher than expected.
