The clarity of our vision is dependent on the accurate focusing of light rays upon the retina the retina is the inner lining of the back of the eye that is sensitive of light ).but some times because of an imperfectly shaped eyeball, lens or cornea (the clear front portion of type eye through which we see), the light rays do not focus accurately on the retina , thereby result in improper vision. These focusing error are called "refractive error " and can be of several types such as myopia (nearsightedness) hyperopic (farsightedness) or astigmatism (distorted vision)
These error can be corrected by using non-surgical procedure like glass or contact lenses or surgical procedure like refractive surgery.
