Keratoconus
Keratoconus is a condition where the cornea, the eye’s clear outer lens, weakens and bulges into a cone shape instead of maintaining its normal dome shape. Symptoms include blurry or distorted vision, sudden vision clouding, frequent prescription changes, light sensitivity, and a history of eye rubbing or allergies. Rapidly worsening eyesight may indicate an uneven curvature of the eye, a common sign of keratoconus. It’s essential to see an eye doctor (ophthalmologist or optometrist) immediately if these symptoms occur. Eye doctors often check for keratoconus during routine eye exams.
