How can alcohol can alter a person's vision?

• A. It makes things look distorted
• B. It sharpens vision
• C. It has no effect on vision
• D. It improves color perception

Answer: (A)

Alcohol disrupts how the brain processes what the eyes see, so vision can become distorted. As a depressant, it slows neural processing and reduces coordination of eye movements, which can lead to blurred or warped images and trouble judging depth. That’s why the statement that objects look distorted is the best match. The other ideas—sharpening vision, having no effect, or improving color perception—don’t fit, since alcohol generally dulls sensory processing and can impair color discrimination rather than enhance it.
