Keratoconus is a progressive eye condition that affects the cornea, the clear front surface of the eye. As the cornea becomes thinner and steeper, it can no longer focus light normally, which leads to blurry vision, irregular astigmatism, glare, and other visual changes. It usually affects both eyes, although one eye may be worse than the other.
Keratoconus often begins in the late teens through the 20s or 30s and may continue to change slowly over many years.
