Air Optix Aqua are monthly contact
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. Package contains 6 lenses.
High Oxygen
Permeability
Air Optix Aqua Contact Lenses
by Alcon (Ciba Vision) take pride (just like Air Optix) in their high oxygen permeability (even 5x higher than other hydrogel
lenses), which allows occasional overnight wear on an extended wearing
schedule. You should consult the Air Optix Aqua extended wearing schedule
with your eye doctor.
We do not recommend you change to these
contact lenses without consulting with your eye doctor first, as these
lenses differ in their optical properties from other contact lens brands.
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.
