What condition involves clouding of the lens in the eye?

• A. Glaucoma
• B. Retinal detachment
• C. Cataracts
• D. Macular degeneration

Answer: (C)

Cataracts are a condition characterized by the clouding of the lens in the eye, which can lead to a decrease in vision clarity. The lens is normally clear and allows light to pass through directly to the retina. When cataracts develop, the proteins in the lens begin to clump together, creating opaque areas that scatter and block light. This can cause symptoms such as blurred vision, difficulty with night vision, and increased sensitivity to glare. Over time, cataracts can progress and significantly impact daily activities and quality of life, but they can often be treated effectively with surgery to replace the cloudy lens with an artificial one. In contrast, glaucoma refers to a group of eye diseases that lead to damage to the optic nerve, often associated with increased intraocular pressure, but does not involve lens clouding. Retinal detachment is the separation of the retina from its underlying supportive tissue, impacting vision due to loss of the retinal function. Macular degeneration affects the central part of the retina, leading to loss of central vision but does not cause clouding of the lens. Understanding the specific characteristics and implications of cataracts is crucial for recognizing how they differ from other eye conditions.
