    1. Process for integrating a photochromic substance into a transparent-based substrate, in particular an ophthalmic lens, of organic material, of the kind in which contact is ensured between such a substrate (10) and a photochromic material (12) formed at least in part of the photochromic substance to be employed, and applying heat to the said material (12), characterized in that is is performed by thermal transfer, i.e., at a temperature sufficient to ensure at least partial sublimation of the photochromic substance.

    (5) METHOD FOR PROCESSING THE EYE LENS
    one
    The invention relates to the production of products containing a photochromic substance capable of changing its color or transparency under the action of a certain radiation, and specifically to obtaining coatings of ophthalmic lenses.
    A method is known for treating an ocular I lens by applying a dispersion of a photochromic substance in an organic solvent to the lens of polyallyl diglycol carbonate, polycarbonate or aliphatic polymethacrylate or polyurethane, followed by heat treatment at 70 C l., 5
    However, this method does not allow to obtain lenses with good physical and mechanical properties.
    The aim of the invention is to increase the adhesion of the photochromic substance. 20
    The goal is achieved in that according to the method of treating an ophthalmic lens by applying a polyalpyl di glycol carbonate polycarbonate on an alum of polymethacrylate or a polyurethane dispersion of a photochromic substance in an organic solvent followed by heat treatment, a mercury dithiozononate derivative is used in a non-graphical pattern with a heat-treated polymerized polycarbonate. cyclohexyl or spiropyran selected from the group: dimethyl 3, 3 isopropyl-1 -indolino-2-spiro-2-nitro-6 (methoxy) (methylthioisopropyl) -8-benzopyran, methyl-3 benzothiazol-2-spiro-2-spropoxy-3) nitro-6-methoxy-8-benzopyran, trimethyl-1, 3,3-indolino-2-spiro-2-nor .tro-6-methoxy-8-benzopyran, methyl-Zbenoxazol-1, 3,2-spiro-2-phenoxy-3-nitro-6-methoxy-8-benzopyran, hexamethyl-3, 5,6,6- oxazin-1,3,2-spiro-3-methyl-3-nitro-6-methoxybenzopyran and trimethyl-3, -oxazole-2-spiro-2-propoxy-3-nitro-6-methoxy-8-benzopyran, and the heat treatment is carried out at the sublimation temperature of the photochromic substance. . The following optical control was carried out for each mixture: the lens under consideration was exposed to ultraviolet radiation for a minute, this radiation being created; this is a 400-watt mercury lamp reproducing the solar spectrum through an interference filter, and the optical density of this lens is measured Irradiation, Od, and then after Irradiation D, the Difference fikD D-Dci characterizes the efficiency of the corresponding photochromic mixture.
