Cataract
What is a "cataract"?
A cataract is a condition where the lens in the eye becomes cloudy, affecting vision. It is most commonly related to aging and happens when protein in the lens clumps together, making it hazy and unclear. Cataracts can also form because of eye injury, certain medications, or medical conditions such as diabetes. Symptoms include blurry vision, difficulty seeing at night, sensitivity to glare, and colors appearing faded. Treatment for cataracts usually involves surgery to remove the cloudy lens and replace it with an artificial one. Cataract surgery is a common and safe procedure that can significantly improve vision and quality of life for those affected.
