Night and Day contacts make wearing contact lenses comfortably and safely for up to 30 days a reality. These soft contact lenses made by CIBA Vision are disposable, so you never have to clean them. Night and Day contacts are not only comfortable, but the material they're made from passes six times as much oxygen as other disposables, which keeps your eyes healthier.

Night and Day contacts are made of a plastic material called silicone hydrogel. Although it's plastic, it's very porous to oxygen. Your cornea requires a flow of oxygen to its surface to remain healthy. And since Night and Day contacts allow more oxygen to get to your cornea than other disposables do, it's safe to wear them overnight for weeks at a time

A problem that all contacts have is the longer you wear them, the more buildup there is of deposits from your eye and from the air. The material that's used in Night and Day contacts resists these deposits and so it's practical to wear them longer than other extended wear contact lenses. In addition they resist accumulations of bacteria, so there's less risk for an eye infection.

Because Night and Day contacts are soft lenses, they're comfortable to wear overnight and day after day. The lenses have been one of the most extensively tested contacts with over 2,000 patient years of research to ensure they provide a safe and real vision solution for most people.

Night and Day contacts are available to correct for nearsightedness and farsightedness. They also can correct a certain amount of astigmatism. For people who wear them for shorter periods than 30 days, they can be cleaned and disinfected before reusing.
