Purevision 6p

PureVision is an extended use lens that strengthens visual acuity and can be used day and night for one month's continuous wear. PureVision is manufactured by AerGel - a silicon based material that counteracts protein- and lipid sediment on your lens, while it also provides your eye with a healthy amount of oxygen. These lenses are much appreciated by people that like to keep their lenses on during sleep. The lens has smooth edges that will synchronize the lens with your eye's actual movement. Always follow your optician's recommendations for use and handling of PureVision since schedule of use is individual and conditions vary.
