Apparatuses and methods for blue-cut lenses

A blue-cut wafer, comprising:

• one or more of blue blocking dyes blended with a thermoplastic resin injection molded into the blue-cut wafer;
• or
• a thermoplastic blue-cut film thermoformed into the blue-cut wafer;
• wherein:
• the blue-cut wafer is configured to reduce by absorption at least a portion of light having a first wavelength range from 400 nanometers to 500 nanometers;
• the blue-cut wafer has a maximum thickness and a minimum thickness within twenty percent of a nominal thickness of the blue-cut wafer;
• and
• a color appearance and a blue-cut performance level of the blue-cut wafer are homogenized in such a manner as ΔE≤1, where ΔE is a color difference between a wafer center and a wafer edge calculated using color-difference formula CIE76.
