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.
