Strain in Eyes

I changed my company in Nov last year and since then I am having problems with my eyes. My PC in office has a CRT monitor that emits all the radiations straight into my eyes. Couple of months back I installed Anti-Glare Screen on my PC. It cuts the radiations to some extent and my eyes were relieved after using it, but for the past 3 days I am again having lot of strain in my eyes.

My eyes turn red and dry just after working for few minutes. There is strain also. I used to do eye exercises daily and I stopped doing it regularly. I guess regular exercise, a glass of Milk and other sources of Vitamin A are good for eyes. Also, take frequent breaks from computer and splash water on eyes and face, this will give some relief.
