1. Eyewear, comprising:
a frame;
a see-through display having color channels and having physical pixels supported by the frame and having display characteristics, wherein a nominal color of each of the color channels and a brightness of each of the pixels is characterized by a manufacturer of the see-through display;
a scanner supported by the frame and configured to determine a gaze direction of a user's eye, and a position of the user's eye with respect to the see-through display;
memory storing a plurality of color maps which characterize a nominal color of the color channels and a brightness of each said physical pixel for each viewing point within an eyebox based on the characterization of the see-through display; and
a processor configured to:
determine the physical pixels having a nonuniform intensity or color for each of the color channels as viewed from the eyebox by using the plurality of color maps and based on the determined gaze direction and position of the user's eye;
generate a color mask as a function of the plurality of color maps and the user's eye gaze direction and eye position; and
adjust a color or intensity of the physical pixels having nonuniform intensity or color to provide uniform color and intensity at the viewing points within the eyebox as a function of the color mask.
