PureVision contact lenses from Bausch & Lomb meet a high standard of visual clarity, using different technologies to meet the wearer’s needs.
PureVision2 lenses have high-definition optics, helping to reduce blurs, halos and glare for better visual clarity. PureVision lenses use Bausch & Lomb’s AerGel technology to do a similar thing.
All the PureVision lenses are made from silicone hydrogel, which makes them exceptionally breathable, allowing more oxygen to the eye than traditional soft hydrogels. Because of this, they can be worn as extended wear contact lenses for 29 nights and 30 days.
