Refractive Error

Refractive errors are vision problems caused when the irregular shape of the cornea results in problems with the light focusing on the retina. The different types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. Refractive errors can be corrected by using eyeglasses, contact lenses, and refractive surgery.
