I'm going to research any developments because it's been many years since I paid any attention to them. But I can tell you the effect was similar to turning colorblind mode on in some video games. First person shooter games were always hard for me to do well at because I'm too slow to react. Everything blends together. With colorblind mode on and set to your specific deficiency, the colors are edited to make them standout. Somewhat like adjusting contrast. So, the colors are different. Nowi can more easily see players on the other team because their uniforms more strongly contrast my team and the elements. This by no means has reversed my color blindness. I don't see like a normal person. The deficiencies are always there. If I put those glasses on again, and you show me colored squares with no context, I'm still not seeing like a normal person and likely can't tell you the color. Write the words STOP, BOY, GIRL on the off them, and now I can tell you which ones are RED, BLUE, PINK. But I'm going to research. Maybe something new is out there.
