What eye condition is characterized by cloudiness of the lens?

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

Answer: (B)

The condition characterized by cloudiness of the lens is cataract. Cataracts occur when proteins in the lens of the eye clump together, leading to a progressive opacification that affects vision. As the lens becomes clouded, light entering the eye is obstructed, resulting in blurred vision and difficulties with glare or night vision. Cataracts are a common cause of vision impairment, especially in older adults, and can develop due to aging, prolonged UV exposure, diabetes, or as a consequence of certain medications. In contrast, glaucoma involves increased intraocular pressure that can damage the optic nerve and lead to vision loss, but it does not specifically cause lens cloudiness. Macular degeneration primarily affects the central part of the retina known as the macula, leading to loss of central vision but is unrelated to the lens structure. Retinal detachment occurs when the retina separates from the underlying tissue, causing vision disturbances but without lens opacity. Thus, cataracts is the only condition mentioned that directly results in clouding of the lens itself.
