Bifocals are a type of multifocal, any lens with more than one power is a multifocals. Multifocals have a wider variety of available patterns than typical bifocals, such as gradual transitions and alternate patterns of power distribution. | Bifocals are a type of multifocal, any lens with more than one power is a multifocals.
