that you might want to consider an Optician's test, especially for computer monitor use. Whilst there may not be any need for spectacles, the optician will be able to recommend 'best practices' for sitting in front of a monitor all day.
If this is at work, your employer may pay for the test, but it won't be too expensive.
The suggestions I had were, keep the room well lit, so the eyes are not straining in the dark, and frequent intervals away from the monitor, say 5 minutes each hour.
I agree that anti-glare is unlikely to help matters. As I understand it they were originally thought to assist with CRT type monitors, but I doubt the same problems arise with LCD monitors.
I am using Samsung B2230 22" LCD monitor
I spend a lot of time in front of my PC..........for about 6-8 hrs a day.
Sometimes I feel discomfort in my eyes with a mild headache. I rest a bit and it almost goes away.
So, I was thinking is an anti glare filter help ?
I used one with my old 15" CRT, which I rarely use now.
