Refractive Errors

The cornea and lens of your eye bend (refract) light rays to focus them on the retina. Refractive errors happen when the shape of your eye prevents light from focusing correctly on the retina. This causes blurry vision. Changes in the eye's shape affect how light rays bend and focus, leading to vision problems.
