Frequency 55 Multifocal Contact Lenses

Get Your Multifocal Contact Lenses from CooperVision

Frequency 55 Multifocal lenses enable eye doctors to fine-tune distance and near acuity to an optimum level. These lenses use "two complementary inverse lenses system" that work together to provide clear vision near, far, and in between.

The design is labeled Balanced Progressive Technology (BPT). The BPT is a process that combines spherical and aspherical optics and unique zone sizes to produce two different lenses. One is D lens, a center distance lens with a progressive add power, for your dominant eye. The other is an N lens, a center near lens with a "degressive" add power, for your non-dominant eye.
