I too work on a computer most of the day.I found that the flourescent lights bother my eyes a lot so I turned them off and use regular desk lamps.I have double vision looking down so my employer got a desk for me that is similiar to a drafting table.All of these things help but the mental part of just trying to focus all day is the worst part. So far I have been able to manage.I also have wondered how insurance companies and social security view Graves Disease as a disability.
