What Are Cataracts?
A cataract is a cloudy area that forms in the natural lens of your eye. A healthy lens focuses light onto the retina, allowing you to see clear and detailed images. Over time, changes in lens proteins can cause the lens to become cloudy, interfering with how light enters the eye.
Most cataracts develop as a natural part of the aging process. However, they can also be linked to conditions such as diabetes, previous eye injuries, prolonged use of steroids, smoking, exposure to ultraviolet light, and certain medical issues.
Cataracts typically develop slowly. You may not notice significant changes at first, but your vision can gradually become more blurred, dim, or distorted as the cataract progresses.
