The Balanced Progressive technology of Proclear Multifocal D/N contact lenses combine spherical and aspheric optics and unique zone sizes to produce create the "D" and "N" lenses that work together to provide a new level of vision quality. Combined with CooperVision's PC Technology that keeps contact lenses moist all day, wearers can enjoy a more comfortable lens-wearing experience.
Proclear Multifocal D/N contact lenses have been designed to address two common eye conditions experienced by many: presbyopia and eye dryness.
Balanced Progressive technology provides two different optical designs (D and N lenses) to utilize the processing power of the visual cortex and enhance vision.
