Understand cataracts, a common eye condition where the lens of the eye becomes cloudy, impairing vision. Symptoms include blurred vision, difficulty seeing at night, sensitivity to light, and fading colors. Cataracts can develop due to aging, injury, genetic factors, or prolonged exposure to UV light. Diagnosis typically involves a comprehensive eye exam, including a visual acuity test and dilation of the pupils. Effective treatments range from prescription glasses and lifestyle changes to surgery, which involves removing the cloudy lens and replacing it with a clear artificial one. Early diagnosis and treatment are key to restoring and maintaining clear vision.
