Refractive Errors
A refractive error is a defect in the optics of the eye that results in a lack of precise focus of the light rays of the retina, causing a blurred image.
Light rays entering the eye cannot be brought to a single focus. Instead they may focus in front of, in back of, or irregularly on the retina.
