have you been able to try any of the lubercating(Refresh) eye drops? (because the tears are the way the eyes say that they need more moisture.)
that may help in the eye symptoms area.


are you able to wear sunglasses when at your desk? or is it a place frequented by others?

maybe trying to keep a food/drink journal for a few days and note which days were better than the others, and see if there is any kind of link to what you may be eating or drinking (caffine, preservatives, dyes, that kind of stuff). and if its more of something or less of something that could be the cause for the unexplained better or worst days.

maybe migraine or headache meds or even prescriptions might help(like pheregin (sp?), but when not used to that med, it will make a person sleep-until a tolerance is built up to the sleepy affect that the med has).

are you allowed to mess with the settings on your computer? or on the monitor? if so, maybe trying different settings on it to see if any of it helps (usually a dimmer(less brightness) screen setting can also help.
