Alcohol has a significant impact on visual perception, particularly concerning peripheral vision. When alcohol is consumed, it impairs several cognitive and motor functions, including those involved in processing visual information. Specifically, it decreases the brain's ability to process visual stimuli that are not directly in the line of sight.

This impairment can lead to reduced awareness of your surroundings, making it challenging to detect movement or objects that are not directly in front of you. As a result, individuals under the influence of alcohol may not notice important visual cues while driving or engaging in other activities that require full attentiveness to the environment.

In contrast, other options like enhancing peripheral awareness, having no effect, or making peripheral vision sharper do not accurately represent the effects of alcohol. Understanding this impairment is crucial for safe driving and overall situational awareness, as it directly correlates with the heightened risk of accidents associated with alcohol consumption.
