- No, only our motor skills will be affected.
- Yes, but only at blood alcohol levels above the legal limit.
Show answer and explanation
Correct answer: Yes, tunnel vision can occur.
Yes. Alcohol narrows your field of vision, and at high alcohol levels, tunnel vision occurs, as the picture shows, with a clear center and blurry sides. Your vision is affected before you reach the legal limit. At around 0.2 g/l in blood, it is already harder to perceive lights and signs clearly.
