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 # designed to correct astigmatism with a
monthly replacement schedule. The innovative silicone hydrogel material,
Lotraflicon B, guarantees high oxygen permeability, which makes the
contacts and your eyes healthier and more comfortable. Air Optix for Astigmatism
are supplied in a pack of 6 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.
