What is the Cornea of the eye?
The Cornea is the most front part of the eye. It is transparent and has a dome shape, similar to the top of a basketball. It focuses light that enters into the eye. For those familiar with contact lenses, the contacts sit on the surface of the cornea. See the diagram below which shows a cross section of the eye for details of eye anatomy. TOP What are Nearsightedness, Farsightedness and Astigmatism? These are conditions of the eye that are inherited in a complex pattern from both parents, but sometimes generations may be skipped so the inheritance pattern is not necessarily predictable. There may also be some environmental factors that contribute to them. In nearsightedness the corneal curvature and focusing power does not match the size of the eye, which is usually too long, and in farsightedness the eye is too short. In astigmatism either the cornea or other parts of the eye have an oval, rather than round shape, thus the focusing of the cornea is distorted. Nearsightedness, farsight
