Abstract
A method and apparatus for forming lenses from a polymerizable monomeric liquid. In accordance with the method of the invention, the activated monomer is encapsulated within lens molds of unique design and is exposed to a precisely controlled atmosphere within the apparatus of the invention. More particularly, during the entire curing cycle of the monomer the molds are uniformly exposed to collimated streams of air maintained at closely controlled temperatures. The streams of air serve to precisely control the temperature of the monomer within the molds and to continuously remove the heat of exotherm from each individual mold.
