Cataracts produce which primary symptom?

• A. Macular degeneration
• B. Retinal detachment
• C. Inflammation of the iris
• D. Clouding of the lens

Answer: (D)

Clouding of the lens is the primary symptom of cataracts. The lens must be clear to focus light onto the retina, but when cataracts develop, proteins clump and opacity forms, scattering and blocking light. This leads to blurred vision, reduced contrast, and often glare from headlights or the sun, with colors appearing less vibrant. Other eye conditions listed involve different parts of the eye—macular degeneration affects the retina’s central area, retinal detachment is a separate problem where the retina peels away, and inflammation of the iris is a distinct inflammatory condition. Cataracts tend to progress slowly and are typically treated with surgical removal of the cloudy lens and replacement with an artificial one. In the meantime, better lighting and updated glasses can help, but the hallmark sign remains the lens cloudiness.
