Abstract
Lenses made of synthetic resins are made by casting a catalyzed monomer which is polymerized up to the hardening point by warming it within a mold formed from two or more glass lenses, assembled together by means of a perimetric gasket and a spring, wherein the shrinkage of the polymer being formed is compensated through catalyzed monomer kept in presence of air outside of the mold, from where it may flow into the interior of the mold in which there is no air. The monomer may be diethylene- glycol-bis-alkyl-carbonate.
