Which symptom is common in cataracts as the condition progresses?

• A. Total blindness
• B. Cloudy and blurry vision
• C. Inability to focus
• D. Tunnel vision

Answer: (B)

As cataracts develop, a common and significant symptom experienced by individuals is cloudy and blurry vision. This occurs because cataracts cause the lens of the eye to become opaque, disrupting the passage of light and leading to a reduction in visual clarity. Patients often describe their vision as seeing through a foggy or cloudy window, which affects their ability to see fine details and colors.

While total blindness can be a possible outcome of cataracts if left untreated, most cases progress slowly, and vision typically remains partially functional for a significant period. Inability to focus can also develop as a cataract worsens, but the primary symptom that people first notice is the blurriness attributed to the lens opacification. Tunnel vision, which refers to loss of peripheral vision, is generally associated with other conditions and is not a typical result of cataracts. Therefore, the progression of cataracts primarily manifests through cloudy and blurry vision, making this the most accurate choice.
