Narafilcon A is a new silicone hydrogel material being used in Johnson & Johnson's new daily disposable lens 1-DAY ACUVUE® TruEye. With a Dk of 100 and a Dk/t of 118 it increases oxygen flow and allows the cornea to breathe naturally through the material.  As a result, lenses that are manufactured utilizing this material, promise better wearing comfort and fewer dry eyes.
