Objective: A method for determined oxygen permeability (Dk) of finished soft contact lens.
Methods: Oxygen permeability(Dk) of 10 group finished soft contact lens was determined by polarographic method, and the values were linearly calibrated using the measured and established Dk values of the specified reference materials.
Results: Only one Dk value fell outside of the requirement of GB 11417.
