What are cataracts?

Also known as: cloudy lens

When the lens of the eye becomes cloudy or opaque, this condition is known as a cataract. Just as the eye appears cloudy, vision for the person with the cataract also becomes cloudy. They occur more frequently with age, but they can also impact infants at birth in some instances (congenital).
