DEF

A lens with more than one optical center (i.e., a bifocal with two, a trifocal with three, a progressive with many).

CONT

A multifocal lens is a lens that contains two or more different powers or corrections. The most common multifocal lenses are bifocals (two powers) and trifocals (three powers). Quadrafocals, which are four different powers in one lens, are prescribed for special purposes. Another type of multifocal lens, the progressive additional lens, is designed to provide clear vision from far to reading distance without break or interruption. They contain no dividing lines between the different viewing sections.
