Too much screen time can cause your eyes to become tired and dry. Your vision may become blurry. You may get headaches. You may even have trouble focusing or have problems with depth perception. This is known as digital eyestrain. The good news is that you can take steps to ease it. Reducing your screen time is one way. If you work in front of a computer, cut back on screen time at home. That means fewer texts and emails, and less TV and computer time.
