What Is Cataracts?
A cataract is a clouding of the eye's natural lens, which sits behind the iris and pupil. It is the leading cause of blindness worldwide, yet it is almost always treatable. Most cataracts develop slowly due to aging, causing no early pain or redness. Vision gradually becomes blurry, colors appear faded, and glare from lights worsens.
When to seek care
See an eye doctor if blurry vision, glare, or changes in color perception are affecting your daily activities — driving, reading, or watching TV. Early cataracts may be managed with updated glasses; surgical referral is made when vision loss impacts quality of life.
