Advantage of contact lens over normal glasses;
**Core Concept**
Contact lenses and glasses are both used to correct vision problems by refracting light correctly onto the retina. The key difference lies in how they correct vision and the comfort they provide to the wearer.
**Why the Correct Answer is Right**
Contact lenses sit directly on the cornea, allowing for unobstructed peripheral vision. This is particularly beneficial for athletes, individuals with high activity levels, or those who enjoy activities that require wide fields of vision, such as driving or watching sports. The absence of frames also reduces the risk of eye injuries from impact or foreign objects.
