Product Info Biofinity are a silicone hydrogel continuous wear contact lens, manufactured by CooperVision and made using their patented Aquaform technology, which creates a hydrophilic silicone hydrogel lens that allows greater levels of oxygen to flow freely through the lens to the eye helping them stay moist and comfortable all day long. Higher oxygen supply lenses are known to create whiter healthier looking eyes for most contact lens wearers. Biofinity contact lenses are designed to be worn all day for up to 6 days in a row (then one night off), they possess and maintain a high level of water to ensure the lens remains soft and flexible, delivering real comfort through the day and night. Combining this perfect balance of water and exceptionally high levels of oxygen, Biofinity feels almost as natural as wearing no lenses at all. Biofinity is a naturally comfortable lens with no additives, coatings, wetting agents or surface treatments so nothing comes between you a more comfortable lens-wearing experience. Biofinity also contains Aspheric optics which enhances vision even in low lighting conditions and helps with peripheral vision.
