Which term refers to a clouding of the lens in the eye?

• A. Cataracts
• B. Arthritis
• C. Asthma
• D. Cancer

Answer: (A)

The term for clouding of the lens in the eye refers to cataracts. Cataracts happen when proteins in the eye’s lens clump together, forming a cloudy area that can grow over time. This cloudiness scatters light, leading to blurred or dim vision, increased sensitivity to glare, halos around lights, and colors that seem faded. While aging is the most common factor, other contributors include smoking, diabetes, longer sun exposure, certain medications, and a family history. In the early stages, simple adjustments like stronger lighting or new glasses can help, but when vision is noticeably affected, surgery to remove the cloudy lens and replace it with a clear artificial one is a common, effective treatment. The other conditions—arthritis, asthma, and cancer—affect joints, airways, and cell growth, respectively, and are not related to the clouding of the eye lens.
