ABSTRACT:
An optical filter which blocks a substantial portion of a selected color of the visual light spectrum from entering one eye. The selected portion is the normal color of an object which is to be viewed by both eyes. The other eye is simultaneously allowed to have a substantial portion of the selected color to enter it. When used to aid a hunter in tracking a blood trail, a substantial portion of the red color (more than 50%) of the blood is blocked from entering one eye while the other eye is allowed to receive a substantial portion (more than 50%) of the red color.
