Dk is the oxygen transmissibility of a material. L is the central thickness of the lens. Dk/L is a good way of comparing different brands of contacts lenses' oxygen permeability. Getting more oxygen to the cornea can be accomplished by increasing the Dk value or decreasing the thickness of the lens. The cornea is the healthiest when the oxygen transmissibility is the highest.
