Abstract: An ophthalmic spectacle lens having transmittance properties that block UV and violet light and partially block certain cyan wavelengths to enhance contrast between blue versus green and partially block certain yellow wavelengths to enhance contrast between green versus red, and keep in accordance with the tristimulus values. Adding wavelength-selective organic dyes provides the entire functional attributes of the current invention or improves the contrast-enhancing attributes provided by a glass wafer having functional rare-earth oxides, either of which improve multi-band spectrum that is balanced in blocking UV light, and adding contrast between the primary colors to optimize color-enhancing functions. When using organic dyes for all functional attributes it is possible to integrate these dyes into plastic ophthalmic materials. Some lenses are polarized.

Abstract: A system and process for making an eyeglass temple co-injection molded with a wire core are disclosed. An eyeglass temple is produced by injecting a first shot of temple substrate material into a mold followed by the shot injection of a portion of wire core into the substrate material while it is still molten or semi-molten followed by a second shot injection of additional molten or semi-molten material to completely fill the mold. The first shot of template substrate is provided in a viscosity and amount sufficient to support the wire core without contact by the mold or external support, and the second shot is provided in an amount sufficient to completely fill and pack the mold and lessen shrinkage problems during substrate cooling and hardening. This produces an eyeglass temple in a desired configuration having an entirely encased wire core. Optionally, a second material can then be overmolded onto portions of the temple.
