Bausch and Lomb ULTRA, by optical pioneers Bausch & Lomb, are monthly lenses designed to cope with the demands of modern life, particularly if you use digital devices for multiple hours a day. We blink less while using a screen so if you work using a computer, for example, you may find yourself suffering from dry and uncomfortable eyes. Bausch & Lomb ULTRA use MoistureSeal Technology to ensure that the lens maintains 95% moisture for up to 16 hours a day. This technology makes the lens surface highly absorbent and the core of the lens adept at retaining moisture. Combined with a high level of oxygen permeability, the result is healthy, hydrated eyes that stay comfortable all day long.
