Extreme H2O 59% Xtra are weekly disposable
contact lenses produced by Hydrogel Vision Corp. Extreme H2O 59% Xtra are a
problem solver for patients who experience significant dryness and discomfort,
and need extra durability and handling benefits provided by slightly thicker
lens design. Extreme H2O 59% Xtra is made with a group 2 non-ionic material
that resists unhealthy Protein deposits. These lenses retain 99% of their water
content on the eye, even under extreme conditions. All lens dimensions and
oxygen permeability present in the first hour of wear, will be present in the
last. Lens comfort, movement, and fit will be stable throughout the day.
