Final answer:
Even low levels of alcohol can impair the eyes' ability to track moving objects. A BAC over 0.025-0.080% begins to impair tracking, and the legal limit of 0.08% entails significant visual impairments. It takes time for the liver to metabolize alcohol and reverse these effects.
Step-by-step explanation:
The ability of the eyes to track can be impaired with even low levels of alcohol intoxication. Alcohol begins to affect individuals after consuming roughly two or more drinks, leading to a wide range of impairments including problems with coordination, judgement, and visual acuity.
At a blood alcohol concentration (BAC) typically defined as more than 0.025-0.080%, a person's ability to track moving objects can be compromised. A BAC of 0.08% is generally the legal limit for intoxication and is associated with decreased reaction times and impairment of visual functions.
