My husband picked up a pair of glasses at Wal Mart for just the computer. He had been to the eye Dr. and had his cataracts done and because he has one eye that is called a lazy eye so he still needs glasses for the computer. he's always worn glasses and finds it hard not to have to wear some. Maybe you can try that. It's amazing what working on something for hrs can do to us. Maybe try taking a break 10 min every hr. this comes to you from me you the hand dr. tells me to do that and I don't even realize the hr is gone until I can't move my hand and have to go back to the dr. Good luck. Sue
