    Vision Tests Directory

    There are many types of vision tests: visual acuity tests, refraction, visual field tests, and color vision tests are a few. These tests help your doctor determine how well your eyes are working. They can help him or her diagnose problems you are having with your eyes such as glaucoma, cataracts, or color blindness. They can also diagnose common problems like nearsightedness or farsightedness.
