Abstract

An article formed by combining a polarizing layer, and a substrate composed of a blend of polymers such that the glass transition temperature of the substrate is adjusted to the vicinity of 100° C. This permits the lens to be thermoformed at temperatures in the vicinity of 100° C., which preserves the integrity of the polarizer. The article can be used as a standalone lens or as a polarizing insert for an injection-molded lens via an injection/compression coining process that results in minimal stress in the lens.
