When you use your eyes intensely, like while driving or looking at a computer, eyestrain is likely to occur. Computers and devices are often the source of eyestrain, which has prompted the name “computer vision syndrome.” The word syndrome might bring up thoughts of frightening diseases, but don’t fret. Computer vision syndrome really just means your eyes get tired when you work on the computer for long periods. Usually all you need to do is rest your eyes or take measures to make your work environment less taxing on your eyes.
