Which ocular condition involves clouding of the lens?

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

Answer: (C)

Cataracts are characterized by the clouding of the lens of the eye, leading to a decrease in vision quality. The lens is responsible for focusing light onto the retina, and when it becomes cloudy, it scatters light, making it difficult to see clearly. This condition can progress gradually, often leading to blurry vision, difficulty seeing at night, or seeing halos around lights. In contrast, glaucoma involves increased intraocular pressure that can damage the optic nerve, leading to vision loss. Retinal detachment refers to the separation of the retina from its underlying support tissue, which can cause loss of vision but is not related to the lens. Macular degeneration affects the central part of the retina (the macula), leading to central vision loss, but again does not involve the lens itself. Thus, cataracts specifically relate to the clouding of the lens, making it the correct answer to the question.
