The new Purevision 2 for Presbyopia contact lenses feature an innovative optical design allowing lens wearers who would otherwise need reading glasses to focus up close, far away and everywhere in-between. Additionally, its silicone hydrogel material allows natural levels of oxygen to reach the eyes while preventing debris build-up, enabling each lens to be worn continuously for up to 30 days.
Material: 64% polymer (Balafilcon A)
