Continuous wear monthly contact lenses with silicone-hydrogel to supply the cornea with enough oxygen when eyelids are closed at night. PureVision are one of the most popular continuous use contact lenses on the market. Bausch & Lomb has limited the production of PureVision contact lenses and currently does not guarantee the delivery of products that are not in stock. For this reason, we sell PureVision contact lenses only in the parameters that are currently in stock. Versions that are not currently in stock cannot be ordered but can be replaced with PureVision 2 contact lenses. Users of the PureVision contacts can start using the new PureVision 2 lenses with a new prescription.
