Working on the computer all day at work can cause some eye problems. Your optometrist can fit you with computer eyeglasses that will help you focus more accurately and with less effort. These glasses can also help you read printed material and there are lenses that have tints and coatings that will make your eyes feel a lot better.  It’s a good idea to take  frequent breaks from looking at the computer by looking outside or somewhere else to relax your focusing eye muscles.  It also might help to have the light a little more dim when working on the computer.
