A bifocal lens means a lens with two credits of focus. A small portion of the eyeglasses lens is reserved for the near-vision correction. The rest of the lens is usually a distance correction.

Index
Lens index is a number that describes how thick or thin your
lenses are. The higher a lens' index is, the thinner it becomes.
Higher prescriptions require higher index lenses, while lower
prescriptions require lower index lenses.
