Sadly, I continue to be a hopeless diachromatic protonope!
Unfortunately, these glasses did not work for me.  I must nmot have the right kind of red-green color blindness, as they simply made things very dark and enhanced slightly some colors I could already see but certainly did not allow me to see reds and greens in any way I had not seen them before.  My brother, also red-green partially hue-deficient, as we have come to call it in our family, had the same experience I had--no difference in color perception,.  I took the color-blind test with the glasses and without  and scored one out of nine both ways--pretty much my usual score.  I believe that these glasses work for some folks with red-green colorblindness, but they did not work for me.  Amazon was wonderful in recharging my credit card immediately.  It was much more disappointing that they did not work than I had expected after 71 years of red-green colorblindness.
