This document discusses different types of lenses and their applications. It describes simple lenses that are made of a single element and compound lenses that contain multiple elements. Lenses are classified based on how they bend light rays, either converging or diverging. Some common applications of lenses mentioned are in magnifying glasses, glasses, cameras, microscopes, telescopes, and binoculars. Medical and other applications are also briefly noted.
