Keratoconus occurs when the cornea begins to thin out. This causes symptoms like blurry vision and increased light sensitivity. Although ophthalmologists aren't sure about the cause, they can help treat it with transplants, UV light, or other small devices. This article by the AOA will help you learn more.
Keratoconus is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone) shaped. This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision.
