Question

drivers may compensate for a lack of visual acuity by wearing contacts or glasses. moving their head more often. leaving larger following distances. using their depth perception.

Explanation:

When drivers have a lack of visual acuity, wearing contacts or glasses directly improves their eyesight to see clearly. Moving the head more often does not solve the core problem of not seeing clearly. Leaving larger following distances is more about safety in case of slower reaction due to other factors rather than compensating for visual acuity. Using depth perception alone cannot make up for poor visual acuity.

Answer:

wearing contacts or glasses.
