What is a possible reason that a teenager may want contact lenses?

A teenager may want contact lenses primarily to enhance their ability to participate in certain sports. This often stems from the fact that contacts provide a wider field of vision and are less likely to impede physical activity compared to eyeglasses, which can be cumbersome and may shift or fall off during play. Contacts also minimize the risk of injury that can arise from glasses during sports that involve physical contact or rapid movements. As a result, they offer practical benefits that can significantly improve performance and comfort in various athletic activities.

In contrast, the other options focus on scenarios that either do not fully represent the primary benefits of contact lenses or are limited in context—for example, using contacts solely with sunglasses or wearing them while driving with eyeglasses does not capture the key motivations behind a teenager's desire for contacts. Additionally, while some may want to change their eye color, this is typically more about aesthetic preferences rather than the functional advantages that contact lenses provide in dynamic activities.
