CIBA Vision’s Focus Dailies are daily disposable contact lenses available in a spherical lens design and are manufactured with AquaRelease, a built in moisturizer that keeps your eyes comfortable throughout the day.  They are worn during the day, discarded every night and replaced with fresh lenses every morning, keeping your eyes free from deposits that can build up and irritate your eyes.  To assist you in finding the lenses in the solution, Focus Dailies lenses are made with a light tint.
