What is the difference between bifocals and varifocals?
A. Bifocals are basically lenses which have two sections with different focuses. Generally they have distance vision in the top half and near vision in the bottom half but they can also be used for intermediate and near vision. The bottom half of the lens comes in different shapes or segments for example round shaped or flat at the top and even right across the lens, this is called an executive bifocal.
