Fit equals comfort with Extreme H2O

Although patients' eyes are not one standard size, disposable contact lenses have generally come in one standard diameter. This leaves up to 27% of patients in a lens that is not the right fit.


A new solution

Extreme H2O Daily and Extreme H2O Weekly are the only disposable contact lenses available in three diameter options (13.6, 14.2, and 14.8) enabling you to successfully fit your small, medium and large cornea patients with the right fit, the first time, for improved comfort.
