Cataracts are one of the most common causes of blindness. It’s inherent in the aging process, so everyone is at risk. Aside from age, other risk factors for cataracts include diabetes, family history, smoking, and drinking.

The cornea is supposed to be smooth and rounded for clear, 20/20 vision (it starkly resembles the surface of a Ping-Pong ball cut in half). However, people with astigmatism have corneas whose surfaces are more curved (reminiscent of the top of a football).
