The lens in lower part is useful for viewing closer objects while the other lens is for viewing distant objects. The focal length of both these glasses is such that these help eye lens to focus light rays coming from outside to get focused on retina of the eye and hence help us to see things clearly.

With the help of modern technology, such bifocal glasses have been developed in which the smaller lens is incorporated into the primary lens, thus removing various issues related to health of eyes of an individual wearing them.
