3 lenses of the same prescription per pack.  These lenses are monthly lenses, which means you can wear them for 30 days before they need to be replaced.  Also available as a 6-pack.

Silicone hydrogel material for very high oxygen transmission.  High oxygen transmission improves eye health, whiteness and comfort.  New more comfortable formulation.  Improved with a co-polymer wetting agent to improve comfort throughout the day.

Note: These lenses are the same as the O2 Optix and have been removed due to the name conflict with the European phone company O2.  These lenses may be supplied in the O2 Optix pack.  As of January 2009, the O2Optix boxes are getting pretty rare and the Air Optix Aqua boxes are the norm.

Air Optix / O2 Optix lenses are also known as Easy Vision Elite when sold by the SpecSavers optometry group.
