The cornea is the clear, dome-shaped tissue that covers the front of your eye and helps to focus light. When you have keratoconus, the cornea gradually thins and bulges outward into the shape of a cone.
This change in the shape of your cornea may cause blurred vision that doesn’t improve with corrective lenses. Over time, more vision problems may develop, including halos, glare, and difficulty with night vision.
Keratoconus signs and symptoms may change as the condition progresses. Symptoms in the early stages include:
More advanced symptoms of keratoconus often include:
Keratoconus may cause you to increase your eyeglass prescription more frequently than you normally would.
