Refractive error, also known as refractive error, is a problem in focusing light accurately on the retina due to the shape of the eye. The most common types of refractive error are myopia, hyperopia, astigmatism, and presbyopia. Nearsightedness makes distant objects blurry, farsightedness and presbyopia make near objects blurry, and astigmatism makes objects appear stretched or fuzzy. Other symptoms can include double vision, headaches, and eyestrain.
