Frequency 55 multifocal contact lenses are one family member of Coopervision’s “total multifocal solution.” The company becomes the first to offer presbyopic correction with multiple product lines such as Ultravue 2000 Multifocal, for high level presbyopes, and Proclear Multifocal, for dry eye sufferers.
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 Frequency 55 Multifocal 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.
How Frequency 55 Multifocal Contact Lenses Work
A Frequency 55 Multifocal D lens has a spherical central for the correction of distance vision and an aspheric concentric zone for the correction of intermediate and near vision. The Frequency 55 Multifocal N lens has a spherical central zone for the correction of near vision and an aspherical concentric zone for the correction of intermediate and distance vision.
Although frequency multifocal lenses initially are worn based on dominant and non-dominant eye, many options exist to maximize visual acuity.
If you’re an editor you may wear the center near lens in your dominant eye, or even center near lenses binocularly. If you’re a golfer you may be better off with center distance lenses in both of your eyes. So, make sure that your doctor’s prescription specifies which your dominant eye is.
Who Needs Frequency 55 Multifocal Contact Lenses
Frequency 55 multifocal lenses are right for you if you’re at an early stage of presbyopia and want to accept a compromise vision. These designs enable eye doctors to fine-tune distance, near and in between vision clarity to an optimum level.
If you’ve been in monovision contacts, or were difficult to adapt to other bifocal contacts designs, frequency multifocal offers better binocularity and stereopsis vision. Since each lens provides full progression of power you may adjust with the center distance lens worn in the eye that was previously used for distance vision with monovision.
Frequency 55 Multifocal is also an excellent choice if you’ve been in monovision and experience an increasing add power. You’re used to having a better distance vision in your dominant eye and near vision in your non-dominant. Transitioning from monovision to frequency multifocal is natural.
But Frequency 55 Multifocal lenses aren’t for you if you can’t accept all distance compromise. They aren’t right for you if you can’t adjust to “Balanced Progressive” vision correction. One wearer reported the lenses created halo effects and her focus kept going in and out.
