    4684222 If you read this patent from google patents , you will learn the most basic anamorphic lens making technology.
    This is from Corning Glass dated 1987.
    There are some glasses which turn to opac state with uv light .
    When they are going to opac , they shrink.
    You have to make a circular mask and put on to the flat special glass.
    Glass is cut circular and there is a circular glass zone around the circular masked glass.
    All glass is flat piece and no molded , no grinded.
    When you put actinic uv light on to the unmasked glass zone , it turns to opac and shrink.
    When around of masked glass circle shrinked , the central area turns to bumped glass and become a lens.
    i think this can be applied to plastics also.

    Best ,
