What term describes clouding of the lenses of the eyes?

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

Answer: (A)

Clouding of the eye’s lenses is called cataracts. The lens should be clear to focus light onto the retina; when it becomes cloudy, light is scattered, leading to blurred vision, glare, halos around lights, and colors that seem faded. Cataracts usually develop slowly, often with aging, but they can also result from injury, certain medications, or diseases like diabetes. The treatment is surgical removal of the cloudy lens and replacement with a clear artificial lens, which typically restores clear vision. This is different from glaucoma, which involves optic nerve damage usually related to high eye pressure; myopia, where distant objects appear blurry because images focus in front of the retina; and presbyopia, an age-related hardening of the lens that makes near objects hard to focus.
