Abstract
Procedure for manufacturing optical and ophthalmic lenses in thermosetting synthetic resin, especially for low power lenses, that is between 0.25 and 1.50 diopters, characterized by the use of tempered glass molds, in which the flexibility of this material, allows the adaptation to the slight variations of curvature that occur during the polymerization in the oven, the two parts of the mold being preferably joined by a flexible plastic material joint, to absorb the contraction of the resin during the polymerization, effecting this the atmospheric pressure.
