As the name suggests, single vision lenses correct only one of the two visions short-sightedness and far-sightedness. On the other hand, bifocal lenses can correct both visions simultaneously.

Bifocal lenses generally have a small part on the lower end of the lens, which helps us see the objects near us clearly. Depending on your requirements and desires, this region can be of different shapes.
