Refractive Error

Refractive Error is an eye condition that occurs when the eye is unable to focus light properly, resulting in blurred vision. It is caused by an irregularly shaped cornea or an inability of the lens to change shape and focus light on the retina. The most common types of refractive error are myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. These conditions can be corrected with eyeglasses, contact lenses, or refractive surgery such as LASIK. Without treatment, refractive errors can cause visual fatigue, headaches, and difficulty with activities such as reading and driving. Treatments to correct these errors can improve one’s quality of life and allow people to see the world more clearly.
