Air Optix Aqua contacts are monthly
disposable lenses by Alcon designed for daily wear. The silicone-hydrogel
material used in these contact lenses is Lotrafilcon B (67%) and the remaining
33% is water. The lenses' high level of oxygen permeability allows for
occasional overnight wear on an extended wearing schedule. This>package
contains three 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.
