The oxygen-permeable monthly lenses have been developed with the well-known 3 in 1 color technology, with one significant difference: the color is located inside the lens, which emphasizes the eyes more. The colored lenses are made from the new silicone hydrogel material Lotrafilcon B with a water content of 33%. The oxygen permeability is up to 6 times higher than that of leading colored lenses. No re-fitting is required for Air Optix Aqua contact lens wearers.
