摘要：
The invention concerns a method which comprises irradiating at least one face of an article with UV radiation, causing the article to be photodegraded over a thickness of at least 1 nullm and contacting the irradiated face of the article with a coloring agent, so as to diffuse the coloring agent in the entire thickness of the photodegraded surface layer of the article. The invention is useful for optical and ophthalmologic articles.
