Contact lenses provide a wider field of vision without distortion primarily because they sit directly on the eye's surface. This placement allows for an uninterrupted visual experience, as they move with the eye and provide a more natural peripheral vision compared to glasses. Glasses can inadvertently create a frame that may limit side vision, as well as produce some distortion in the lenses depending on their shape and prescription strength.

In contrast, because contact lenses conform to the curvature of the eye, they can minimize factors that typically affect vision with glasses, such as distortion from the lens edges and the physical limitations of a frame. Consequently, contact lenses enable clearer vision in a full range, particularly important in dynamic situations where peripheral awareness is essential, like sports or driving.

Other options discuss aspects of maintenance and prescription requirements, which are relevant but do not directly pertain to the differences in vision quality between contact lenses and glasses. Maintaining contact lenses can indeed be more challenging and requires proper care, and although prescriptions are necessary for both modes of vision correction, this doesn't relate to how they influence visual experience.
