Which term describes clouding of the lens leading to blurred vision?

• A. Conjunctivitis
• B. Cataract
• C. Inner ear
• D. Ischemic stroke

Answer: (B)

The main idea is recognizing a condition that clouds the eye’s lens, leading to blurred vision. That condition is cataract—the lens becomes cloudy, which scatters light and blurs vision, often gradually with aging but can result from injury or certain diseases. Treatment typically involves surgical removal of the cloudy lens and replacement with an artificial one, which can restore clear vision.

Conjunctivitis is an inflammation of the eye’s surface and usually causes redness, discharge, and itching, not lens clouding. The inner ear deals with hearing and balance, so it doesn’t directly affect vision. An ischemic stroke is a brain event that can cause sudden vision changes or loss, but it’s not caused by clouding of the lens.
