As you age, so do your eyes. You might find that you have difficulty reading small print or that you need brighter lighting at your workstation. In addition, eye diseases that could lead to more-serious vision problems become more common with age.
Consider cataracts. A cataract is a clouding of the normally clear lens of the eye. Most cataracts develop slowly and don't disturb eyesight early on. At first, stronger lighting and eyeglasses can help you deal with cataracts. Eventually, however, cataracts can interfere with your vision. Left untreated, cataracts can lead to blindness.
