I have invisible colors. My optic nerve is damaged due to progression of glaucoma. Due to damage to the optic nerve, it is difficult to discern colors. Colors with little contrast difference are often unrecognizable. Street scenes often appear in black and white. t's a little dark and I can't see the color. Light constantly changes the color of my vision. Car lights, shop windows. Billboard neon sign. street lamp. My vision changes color like a camera with auto white balance gone awry. My vision is blurry as if I were wearing a monocle. Please,See Pursuit of Invisible Vision.
