The resinous component is selected from the group consisting of (i) a blend of (co)polycarbonate resin and (co) polycaprolacone, and (ii) a copolymer containing carbonate and caprolactone structural units. The composition, characterized in that it is free of photochromic colorants, may be molded by thermoplastic means, and the molded article is then dippeddyed by immersion in a tinting solution.
