Biofinity Multifocal contact lenses by CooperVision are monthly lenses designed to correct presbyopia. In addition to the benefits of the silicone hydrogel material, they feature the unique Balanced Progressive and Aquaform technologies that keep the lenses naturally moist and provide excellent vision correction.  What special technologies are used in Biofinity Multifocal lenses? The unique silicone-hydrogel material ensures hydration of your eyes while the higher oxygen permeability prevents eye fatigue and irritation. Advanced design and modern know-how are combined in the Balanced Progressive Technology, which incorporates multiple zones of vision correction in both lenses to provide clear vision near and far. In addition to the excellent vision correction, Aquaform technology offers even greater wearing comfort with hydration and sufficient oxygen throughout the day. Thanks to the natural wettability of the lenses, your eyes are less stressed.  What is presbyopia? Presbyopia is an age-related eye condition that makes it difficult to see nearby objects sharply. It usually occurs after the age of 40. The cause of the visual impairment is the reduced elasticity of the eye, which makes it difficult to focus at close distances. With Biofinity Multifocal lenses, you can read newspaper articles as well as distant street signs. The Balanced Progressive technology allows you to see close and distant objects, and everything in between, pin sharp without sacrificing comfort and visual quality. Biofinity Multifocal contact lenses are designed for daily use with monthly change. They can also be worn continuously for 30 days after confirmation by your optician.
