Keratoconus is a condition in which the central cornea thins and takes on an irregular shape. Any light that passes through the cornea becomes distorted, thereby making this condition difficult to treat with glasses or conventional contact lenses. Keratoconus usually develops in the late teens and early twenties and, in it's early stages, presents as a slight blurring of vision and an increased sensitivity to light. As the disorder progresses, vision deteriorates and light sensitivity often increases.
