The cornea, which is the outermost part of the eye acts as an aperture to the light rays entering the eyes. In simple words, it controls the amount of light. It is a transparent membrane, which refracts or bends the light rays amounting to the maximum part of focusing. The light rays focus on the retina after passing through a lens. The image forms on the retina, from where the signals are sent to the brain via optic nerves. Brain interprets those signals and thus, it perceives the image.
If the cornea or the lens is unable to bend the light rays properly, the rays do not focus on the retina. They either fall short or focus beyond it, this causes hypermetropia and myopia respectively. When there are irregularities in cornea or lens leads to astigmatism. Lasik surgery aims in treating cornea to achieve the perfect vision.
