Lenses change the paths of light.

Lenses change the paths of light. A light ray bends as it enters glass and bends again as it leaves. Light passing through glass of a certain shape can form an image that appears larger, smaller, closer, or farther than the object being viewed. 30.1 Converging and Diverging Lenses.
