Multifocal lenses - Varifocals
Varifocal lenses are the most common type of multifocals. These lenses have your distance prescription set at the top of the lens, and this gradually blends to your reading prescription at the bottom. A great all-rounder for all tasks.
Multifocal lenses - Occupationals
Occupational lenses are a type of multifocal lens. These blend just your reading and intermediate prescriptions. These give wider fields of view so they make working between a computer, laptop and paper materials more comfortable.
