Cataracts is the clouding of the lens that contributes to blur, glare, and poor night vision. Depending on the size and location of the cataract, it can interfere with vision. Most cataracts start developing around 50 years of age, however on some occasions it can also be developed in infants and children. In addition, other factors can contribute to cataract development such as diabetes, medications, smoking, and UV rays. Cataracts are usually treated with surgery, by removing the lens and replacing with an artificial lens. During your eye exam, optometrists can determine whether or not your lens is ready for cataract surgery.
