The Contact Lens Oxygen Permeability Tester (Polarography Method) is a precision instrument designed to measure the oxygen permeability (Dk) of soft and hard contact lenses, hydrogel, silicone hydrogel, and other high oxygen permeability materials. The instrument provides accurate, repeatable measurements critical for lens manufacturers, laboratories, and research institutions. A complete measurement setup typically includes the main host, electrode assembly frame, electrodes, central thickness gauge, and a controlled temperature and humidity environment, ensuring compliance with international and national standards.
Application
(1) Measurement of oxygen permeability of soft contact lenses (hydrogel, silicone hydrogel).
(2) Evaluation of oxygen permeability in rigid or hard contact lenses.
(3) Quality control of contact lenses in manufacturing facilities.
(4) Research and development of new lens materials with enhanced oxygen permeability.
(5) Verification of compliance with regulatory standards for ophthalmic products.
(6) Laboratory testing of lens prototypes for performance evaluation.
Standards
(1) ISO 18369 – Ophthalmic optics – Contact lenses – Requirements and test methods.
(2) GB/T 11417 – Contact lens oxygen permeability measurement.
(3) ANSI Z80.20 – American National Standard for Contact Lens Oxygen Permeability.
(4) ISO 9913-1 – Ophthalmic materials – Oxygen permeability of polymer materials.
(5) ISO 9913-2 – Ophthalmic materials – Polarographic method for Dk measurement.
