Eye Diseases and Conditions

Nearsightedness is a vision condition that affects approximately 20% to 30% of the population. People who have this vision problem can see objects that are close very clearly, but far away objects appear blurry. Having a long eyeball or cornea that has too much curvature causes light entering the eye to focus in front of the retina instead of on it. This distorts vision. Nearsightedness is easily correctable by wearing glasses or contact lenses or undergoing refractive surgery.
