In eyeglasses, bifocal lenses contain two different prescriptions: an upper section to allow for distance vision and an additional power on the bottom part of the lens to aid in close up focus. The result is vision clarity at both distance and near with one pair of glasses.

Bifocals: A bifocal lens is created with two different areas of vision correction, which are divided by a distinct line that sits horizontally across the lens. The top portion of the lens is used for distance, while the bottom portion of the lens is used for closer vision.
