Bottom line: I never, ever, had a clue as to how much I was missing.
Some years back, my optometrist diagnosed me with red-green color blindness, though at the time he didn't give it a name. According to the online tests provided by Enchroma, I have Strong Protan color blindness, a type of red-green color blindness. I confirmed the results of the online test by taking it twice on two different monitors as color calibrations can vary from monitor to monitor. I ordered a pair of outdoor glasses, and from the day I first put them on, my world changed. I now ware my glasses wherever I go. As soon as I finish this review, I am ordering an indoor pair.
Just a side note: one of our favorite things to do is watch the sunset over the ocean. And while I always saw beauty as best as I could perceive it, my wife really knew otherwise. She had been trying to get me to get a pair of these for several years. I finally listened and only wish that I had gotten them sooner. If you have a spouse or significant-other that wants to share the world with you in the rich, vibrant colors that God has given us, get a pair of these, go out, and enjoy a real sunset.
