Abstract: Apparatus has a closing element (12) with two jaws (12',12) whose internal surfaces are covered with synthetic material and grip two mold shells. The jaws are movable relative to each other. Each jaw may be made of metal and has a semi-cylindrical internal surface for gripping the edges of the mold shells. The jaws are mounted in a frame (19). The upper or lower jaw is movable vertically and the other jaw is fixed. Double acting jacks (29) move the jaw.

Abstract: The method consists in introducing into a reactor containing the ophthalmic article and the additive a fluid in supercritical state and maintaining this fluid in the reactor for the time required for incorporating the additive into the ophthalmic article, eliminating the fluid in supercritical state and recuperating the ophthalmic article in which the additive has been incorporated. The invention is applicable to the incorporation of photochromic substances.
