Yes. The oxygen permeation properties of soft contactlenses include two indexes: oxygen permeability Dk and oxygentransmissibility Dk/t, and the latter is directly related to the thicknessof the lens. Therefore, when changing the center thickness of the lens,the manufacturer should consider the effec...
