ABSTRACT:
A method of making plastic aspheric lenses by casting a liquid lens monomer in a container having the aspheric curve present on the bottom of the container, polymerizing the lens monomer to form a transparent solid having an aspheric optical surface formed within the container and cutting a second optical surface on the solid lens material with the container supporting the lens material during the cutting and polishing operation.
