What term describes clouding of the lenses in the eye?

• A. Glaucoma
• B. Myopia
• C. Cataracts
• D. Presbyopia

Answer: (C)

Clouding of the lens in the eye is called cataracts. The lens normally focuses light onto the retina, but when it becomes opaque, vision becomes blurred, colors may seem faded, and glare from lights can be troublesome. Cataracts most often develop with aging, and risk factors include diabetes, smoking, and prolonged sun exposure, though trauma or certain medications can contribute. In contrast, glaucoma involves damage to the optic nerve usually from elevated eye pressure and tends to cause gradual loss of peripheral vision; myopia is nearsightedness where distant objects appear blurry; presbyopia is age-related loss of near focus due to loss of lens flexibility. The term described here correctly identifies the cloudy lens and its impact on vision.
