How does alcohol affect a person's vision while driving?

Alcohol has a significant impact on a person's vision, particularly concerning the distortion of distance and speed perception. When someone consumes alcohol, their ability to accurately judge how far away objects are and how quickly they are approaching diminishes. This is due to alcohol's effects on the central nervous system, which impairs cognitive functions and sensory perceptions.

As a result, individuals may struggle to correctly gauge the distances to other vehicles, road signs, and pedestrians. This impaired judgment can lead to dangerous driving situations, as they might misinterpret how fast they are closing in on obstacles or how much space they have to maneuver safely. Such distortions increase the risk of collisions, making it crucial for drivers to understand how alcohol can compromise their visual acuity and overall driving ability.
