What condition is characterized by clouding of the lens?

Cataracts are characterized by the clouding of the lens of the eye. The lens is responsible for focusing light onto the retina, and when it becomes cloudy due to cataract formation, it can lead to blurred vision and difficulty seeing in low light or at night. Cataracts can develop as part of the aging process or due to other factors such as UV exposure, certain medications, or underlying health conditions, like diabetes.

Understanding cataracts is essential as they are one of the leading causes of vision impairment worldwide, and timely intervention through surgical procedures can restore clarity of vision by replacing the cloudy lens with a clear artificial lens. Identifying cataracts is crucial for vision professionals, as it directly influences treatment options and patient care.
