Oxygen permeability describes the amount of oxygen that is able to pass through the contact lens to reach the eye. Its value is expressed in Dk/t. The earliest models of soft contact lenses had a level of oxygen permeability of around 6–8 Dk/t. Today’s silicone hydrogel lenses feature oxygen permeability levels of around 150 Dk/t.
