    Abstract: A blue-cut wafer can be coupled to a lens, such that the blue-cut wafer can be configured to reduce by absorption at least a portion of light having a first wavelength range from 400 nanometers to 500 nanometers, preferably from 400 nanometers to 460 nanometers. The blue- cut wafer can permit light having a second wavelength range, the second wavelength range being greater than the first wavelength range, and homogenize a color appearance and a blue-cut performance level of the blue-cut wafer based on the blue-cut wafer having a maximum thickness and a minimum thickness within twenty percent of a nominal thickness of the blue-cut wafer.

    Abstract: A method of manufacturing an optical lens (417, 901), comprising: obtaining (S301) a transparent thermoplastic (TP) carrier (410, 1210) with at least one smooth surface; printing (S305), via a 3-D printer on the side opposite to the at least one smooth surface of the transparent TP carrier (410, 1210), at least one transparent layer (420, 1220) using a thermoplastic filament (403), each transparent layer (420, 1220) having a predetermined light filtering property, thereby forming a functional layer (420, 1220); and performing (S307) an injection over-molding process (415) to fuse bond the functional layer (420, 1220) to a thermoplastic substrate thereby forming the optical lens, wherein the at least one smooth surface of the transparent TP carrier (410, 1210) forms a smooth surface of the manufactured optical lens (417, 901).

    Abstract: Embodiments of the disclosure relate to color additives and color formulations for offsetting or reducing yellowness index of blue-cut lenses. The color additives and color formulations are selected to provide color neutrality and color homogeneity for blue-cut lenses. Resins formulations comprising at least two color-balancing color additives are also disclosed.
