  3. Oxygen permeability

Oxygen permeability

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.

Oxygen permeability and types of lenses

Oxygen permeability and types of lenses

Hydrogel lenses use water in the lens to transport oxygen. Therefore, a higher water content means a greater level of oxygen permeability, with a maximum Dk/t of around 40. In silicone-hydrogel lenses, oxygen is not transported by water, but rather through silicone molecule chains. The silicone molecules in these types of lenses can have an oxygen permeability of more than 100 Dk/t.
