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.
