Bausch & Lomb ULTRA with MoistureSeal technology is a new generation silicone hydrogel from B&L. It features their unique 2 phase polymerisation process which results in a lens with exceptionally high oxygen transmissibility, low modulus and high water content. Bausch & Lomb ULTRA hence provides excellent material properties, designed with comfort in mind and also featuring aspheric optics providing low spherical aberration.
