What is Refractive Error?

Refractive error is a very common vision condition in which the shape of the eye prevents light from focusing precisely on the retina, resulting in blurred vision at certain distances. The main types are myopia or nearsightedness, hyperopia or farsightedness, astigmatism from irregular corneal curvature, and presbyopia, the age-related loss of near focusing ability. It is not a disease of the eye tissue itself but rather an optical mismatch between the eye's length or shape and its focusing power. Refractive errors are extremely common, easily diagnosed through a standard eye exam, and highly correctable with glasses, contact lenses, or surgery.
