What Do you mean by cataract? A cataract occurs when the eye’s natural lens becomes opaque, often due to aging, high blood sugar, eye injury, certain medicines, or long-term UV exposure. Signs may include blurred vision, halos near lights, dull colours, frequent power changes, and trouble driving at night.
