Biofinity is a 3rd generation silicone hydrogel contact lens product which is extremely comfortable, made possible by the exclusive Aquaform Comfort Science: High oxygen transmissibility which makes the lens material breathable so more oxygen reaches the eyes, helping keep them clear and white with less irritation. The lenses are naturally and uniformly wettable so they stay moist without other additives helping minimize deposits and maximize comfort, and have optimum modulus which means they are very soft and flexible overall providing lasting comfort!
