ABSTRACT:
An uncoated lens, especially for use as the lens of a fog light or a headlight for an automobile, and having particularly good resistance against the environmental effects which are inherent in this environment, is formed of a colorless, transparent copolyamide having a glass transition temperature of at least a 170.degree. C., blended with a homopolyamide, and wherein the copolyamide is formed from at least one cycloaliphatic diamine with two cyclohexane rings, and at least one aromatic dicarboxylic acid which is predominantly isophthalic acid. The copolyamide may optionally contain up to 20 mol % of a further polyamide forming monomer of at least one lactam or an omega-aminocarboxylic acid. The homopolyamide is preferably one of PA6, PA11, PA12, PA66, PA69, PA610 or PA612. The cycloaliphatic diamine of the copolyamide is preferably bis(3-methyl-4-aminocyclohexyl)-methane.
