ABSTRACT:
A method and apparatus for immobilizing a contact lens without distortion to facilitate accurate measurement of its physical dimensions. The lens is floated on the surface of a liquid just out of contact with a support member. The support member is disposed to interact with the lens, through surface tension effects of the liquid, to immobilize the lens on the surface of the liquid.
