Lenses Stay Moist & Comfortable Even at the End of the Day Omafilcon A is the only lens material cleared by the FDA for the claim: "may provide improved comfort for contact lens wearers who experience mild discomfort of symptoms relating to dryness during lens wear." Proclear Multifocal is the only contact lens designed to address two common conditions experienced by those with aging eyes: presbyopia & eye dryness. Only Proclear® Multifocal contact lenses combine a superior lens design, Balanced Progressive™ Technology, with a unique lens material made using our patented PC Technology™. The result - Contact lenses that give you great vision at every distance while staying moist & comfortable, all day long. Proclear Multifocal contact lenses focus light from both near & far distances to the back of the eye, creating the clearest possible image. This unique system uses two different, yet complementary, lenses that work together to provide clear vision near, far, & in between. Proclear Multifocal contact lenses are made using PC Technology, which creates a unique material containing molecules of phosphorylcholine (PC), a substance found naturally in human cell membranes. These miracle molecules attract & surround themselves with water, keeping Proclear contact lenses moist & comfortable. It's a level of comfort so unique, only Proclear contacts are cleared by the FDA for the claim: may provide improved comfort for contact lens wearers who experience mild discomfort or symptoms relating to dryness during lens wear.
