Which condition is characterized by clouding of the lens of the eye?

Cataracts is the condition characterized by clouding of the lens of the eye. This clouding occurs when proteins in the lens begin to break down and clump together, causing the lens to become cloudy and obscuring vision. As cataracts progress, they can lead to blurry vision, difficulty seeing at night, and increased sensitivity to glare. This condition is one of the most common causes of vision impairment and can often be treated through surgical procedures to replace the cloudy lens with an artificial one.
