How does alcohol impair vision?

• A. It can dull vision, slow your ability to focus and cause double vision
• B. It improves night vision
• C. It enhances color perception
• D. It prevents any vision changes

Answer: (A)

Alcohol affects the brain and the nerves that control eye muscles and how we process what we see. That disruption makes vision less sharp, slows the eyes’ ability to adjust focus, and can cause the eyes to misalign, producing double vision. It can also reduce contrast sensitivity and brighten glare, which further degrades vision, especially in dim light or at night. So the description that matches these effects—duller vision, slower focusing, and double vision—best reflects how alcohol impairs sight. The other options describe improvements or no change, which don’t align with how alcohol typically affects vision.
