摘要:
The process comprises: (a) the introduction into a mould of a composition which is polymerizable into a transparent organic glass (b) the polymerization of the composition under conditions such that the resulting substrate made of transparent organic glass has at least one thin surface layer polymerized to a degree of progression and/or of crosslinking which is appreciably lower than that of the remainder of the substrate, and optionally (c) a stress-relieving thermal anneal of the substrate. Application to the manufacture of finished or semi-finished optical or ophthalmic items, in particular photochromic optical or ophthalmic items.
