title: Multifocal lens decentration and size as a function of reading distance.
abstract: A new technique for bifocal size determination and decentration is discussed in detail. Tables based on bifocal power, reading distance and refracting power of the distance lens are presented in order to make bifocal lens selection less complicated.
