Air Optix for Astigmatism Monthly Contact Lenses
Alcon has
discontinued Air Optix for Astigmatism and introduced a new
version of Air Optix plus HydraGlyde for Astigmatism. If the
old version is not available, we send the new version for the same price. Alcon
recommends switching to the new version without consulting an eye specialist.
Air Optix for Astigmatism are silicone-hydrogel contact
lenses by Alcon designed to
correct astigmatism with a monthly replacement schedule. The innovative,
silicone-hydrogel material, known as Lotraflicon B, guarantees high oxygen
permeability, which enhances the comfort of wear. This package of Air Optix for
Astigmatism contains six 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.
