Symptoms

Signs and symptoms of keratoconus may change as the disease progresses. They include:

• Blurred or distorted vision
• Increased sensitivity to bright light and glare, which can cause problems with night driving
• A need for frequent changes in eyeglass prescriptions
• Sudden worsening or clouding of vision

When to see a doctor

See your eye doctor (ophthalmologist or optometrist) if your eyesight is worsening rapidly, which might be caused by an irregular curvature of the eye (astigmatism). He or she may also look for signs of keratoconus during routine eye exams.
