Compared to hydrogel contact lenses, silicone hydrogel enables five times more oxygen to reach the cornea. Below is a list of most contact lens materials on the market, their water percentage, their oxygen permeability rating, and manufacturer brands. Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses. The drawback of silicone hydrogel lenses is their tendency for the lens to collect more debris and protein deposits from your tears. Dumbleton K, Jones L, Chalmers R.
