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.
