2D oxygen-tension contours for contact lens and corneal system: (A) is SCL wear, (B) is SL wear, and (C) is no lens wear. Contour for the sclera is not displayed as the oxygen tension is set to be that of the blood. Oxygen permeabilities for both lenses are 100 Barrer. Lens and PoLTF thickness profiles are provided in Figure 2. Colors are interpreted from the vertical bar on the right. Red color indicates high oxygen tension and navy color indicates low oxygen tension. The unit of oxygen tension is mm Hg.
