A cataract is a cloudy area that forms in the lens of the eye. It can make vision blurry, dull, or less sharp, and it often gets worse slowly over time.
People usually use the word “cataract” when talking about age-related eye problems, but it can happen for other reasons too. In daily life, someone with a cataract may notice trouble reading, driving at night, or seeing clearly in bright light.
Meaning & Usage
In simple English, a cataract means the eye’s lens has become cloudy. Doctors use this word to describe a common condition that affects vision.
Examples
For example, a person might say, “I have cataracts, so my vision is getting blurry.” Another common use is in medical checkups, when an eye doctor explains that a cataract may need treatment or surgery.
