Refractive Errors

Refractive Errors

Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina. The length of the eyeball (longer or shorter), changes in the shape of the cornea, or aging of the lens can cause refractive errors.

The most common types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), presbyopia, and astigmatism.
