What is a typical symptom of a visually significant cataract?

• A. Gradual painless blurring or glare, with reduced color perception
• B. Sudden severe eye pain with halos around lights
• C. Flashes of light with curtain-like loss of vision
• D. Redness and tearing of the eye

Answer: (A)

When a cataract has become visually significant, the main sign is a gradual, painless blur of vision accompanied by glare and a faded sense of colors. This happens because the clouding of the lens scatters light and reduces contrast, making everything look hazy and colors look less vivid. This description—gradual painless blurring with glare and reduced color perception—best fits cataracts. The other scenarios describe different eye problems: sudden severe eye pain with halos around lights is typical of an acute glaucoma attack; flashes of light with curtain-like loss of vision points to retinal detachment; redness and tearing usually indicates conjunctivitis or corneal irritation.
