Normal Eye

The cornea is the clear front part of the eye. Think of it like a window that light has to pass through to enter your eye. Behind the cornea is the Lens that focuses the light onto the Retina at back of the eye. The Retina converts the light into nerve signals that your brain can understand. In a normal eye, the cornea is smoothly rounded. The light passes through evenly onto the lens.




Keratoconus Eye

In an eye with Keratoconus, the cornea thins and bulges out into an irregular cone shape. The light coming through is distorted the lens cannot focus it properly and vision is affected. The name actually means coning of the cornea, although the actual distortion of the cornea is not as regular as a cone. In fact it’s this irregularity that makes the vision so hard to correct.
