Tried and true since 2008, Biofinity Multifocal contact lenses not only optimize both near and far vision, but innovative lens design lets you see that awkward middle distance just a bit clearer. Biofinity surpasses other multifocal lenses with ADD power up to +2.50. Combined with oxygen permeable comfilicon A material, CooperVision applies several exclusive technologies to meet your vision needs without sacrificing comfort. Balanced Progressive Technology – Biofinity Multifocal lenses come in D and N varieties, both allowing you to view distance along a continuum. This technology makes these lenses more adaptable than your two option bifocal eyeglasses. D lenses allow for far sight in the center of the lens. As your eye approaches the edge of the lens, the material gradually adapts to near vision. If you spend most of your time looking at things close-up, N lenses flip the design and put near vision in the center. Aquaform Technology – Limited to Biofinity lenses, CooperVision builds natural wettability into the molecular structure of their lenses rather than relying on coatings which can wear away. A round-edged design and low modulus further decrease rubbing on your eye and enhance comfort. Biofinity Multifocals are monthly wear lenses with an extended wear option. More cost-effective than daily wear options, the above-mentioned technologies allow the lenses to last an entire month, assuming proper care, without loss of safety or comfort. If recommended by your doctor, Biofinity Multifocal lenses allow for up to six nights of extended wear. This means wearing your lenses through the night and only dealing with the hassle of removal once a week. The going retail price for Biofinity Multifocals is $73 for a box of six lenses.
