The Bausch + Lomb ULTRA for Astigmatism contact lenses are made of a new silicone hydrogel material, Samfilcon A. This material is manufactured by means of the MoistureSeal Technology. This technology is a unique two-phase process that results in an exceptional combination of high oxygen permeability (DK / t) and low modulus *. The Samfilcon material contains PVP (Polyvinylpyrrolidone), a water-retaining polymer which ensures excellent wetting.
