Proclear Sphere Monthly Contact Lenses Proclear Sphere contact lenses are high-quality contact lenses with many benefits. Proclear Sphere contact lenses are suitable for users affected by dry eye syndrome and those who wear contact lenses 12 hours a day or work in air-conditioned rooms. Hydration and oxygen permeability Proclear Sphere are monthly contact lenses by Cooper Vision. Thanks to their material composition (38% Omafilcon B polymer and 62% water content) and their thinness in the middle, Proclear Sphere contact lenses have outstanding oxygen permeability and keep your eyes hydrated. High Biocompatibility Proclear Sphere contact lenses also contain a synthetic imitation of phosphorylcholine, a substance found naturally in human cell membranes which is responsible for retaining water balance. Proclear Sphere contact lenses are also characterized by their high resistance to dehydration. The lenses remain pleasantly moist throughout the day. Phosphorylcholine also ensures the high biocompatibility of Proclear Sphere contact lenses, which means the lens, although a foreign body, is well-tolerated. Phosphorylcholine forms a protective film on the surface of the lens which prevents the formation of protein or lipid deposits that can cause discomfort and decrease oxygen permeability. A package of Proclear Sphere contains 6 soft lenses.
