Abstract: An article, such as a lens article (10, 10?, 10?, 100) containing a first component, e.g., a filter (14, 14?), or component thereof, having a minimum degradation temperature, and a second component, e.g., a substrate (22, 22?), comprising a blend of first and second thermoplastic polymers. The first polymer, which has a glass transition temperature higher than the minimum degradation temperature of the first component, is selected based upon its ability to provide the article with one or more desirable characteristics. The second polymer is blended with the first polymer in a predetermined amount that provides the blend with an adjusted glass transition temperature lower than the minimum degradation temperature of the first component so that the first and second components can be heat processed together at a temperature greater than or equal to the adjusted glass transition temperature but below the minimum degradation temperature.

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.

Abstract: A polarized lens formed by an injection/coining injection molding process is disclosed. The polarized lens includes a polarizing insert formed from a polarizer sandwiched between two layers of cellulosic material. The polarizing insert is surrounded by high-impact polymer formed by a two-step injection/coining process of injection molding that results in minimal stress in the lens.
