Air Optix Aqua contacts are monthly disposable
lenses by # designed for daily wear. The silicone hydrogel material used in
these contact lenses is Lotrafilcon B (67%) and the remaining 33% is
water. These contact lenses are equipped with a special, high level of
oxygen permeability, which allows occasional overnight wear on an
extended wearing schedule. This package contains 3 lenses.

Regarding the oxygen permeability of these lenses, are you concerned about
the difference between values indicated on our website and those on the box? No
worries, they are completely the same! On our website, we use an
industry-standard number showing oxygen permeability in relation to thickness of
the lens -- shown as (Dk/t). This is a value calculated by dividing the oxygen
permeability of the lens (Dk) by the thickness of the lens (t). Most
manufacturers provide a (Dk/t), which is why we've chosen to use it for all our
products. However, your box of lenses may only show the (Dk) value. This just
means that your box is showing the base value. It also means that there is, in
fact, no difference between the number we show and the one that's on your box.
