We see through the cornea, which is the clear, central part of the front surface of the eye. Normally, the cornea has a round shape, like a ball. Sometimes, however, the structure of the cornea is just not strong enough to hold this round shape. The normal pressure inside the eye makes the cornea bulge outward like a cone. This condition is called keratoconus.
