O-Perm 30 contact lenses are gas permeable contact lenses manufactured by Optical Polymer Research.  The lenses are designed to take full advantage of oxygen permeability.  O-Perm 30 contacts use stable, stress free polymers to provide a medium diffusion constant (dk) in a lens capable of being shaped to a wide array of designs.  The lenses are made with a light tint to help you locate the lenses in the solution.  This tint will not alter the color of your eyes.

Lens Material
O-Perm 30 contact lenses are made of 100% Polymer (sterafocon A) materials.
