Objective To find a series of reference materials that can be used to calibrate the oxygen permeability （Dk） of contact lenses using polarographic analysis. Methods A control study was performed on two different production samples to create a reference for oxygen permeability coefficients. The Dk of a rigid contact lens material was first measured by a coulometric method， then selections from samples of material were analyzed for Dk values. On the basis of the results， the selected samples were verified for use as reference material. Results For the four Boston rigid contact lens materials， the consistency of oxygen permeability met the requirements when the same production sample was chosen. The Dks， expressed as 2 times the standard deviation at a 95% confidence level， were 2.10%， 0.64%， 1.48%， and 3.16%， respectively， which conformed to the requirement of GB/T11417.7-2012《Ophthalmic optics. Contact lenses. Part 7： Physicochemical properties test methods》. That is， the Dk reference for the material shall be known within the range of ±5%. Therefore， the average values of the oxygen permeabilities obtained from more than 6 samples can be regarded as the nominal value for a reference material. Conclusion The four Boston rigid contact lens materials （ES， EO， XO and XO2） basically meet the test requirements of oxygen permeability for the soft contact lens material available on the market.
