I love them, but…
For the first time in my 76 year life I can see red! I now understand why stoplights are red - before my protan Enchroma my they looked dark reddish brownish and they didn’t stand out. This plus the very helpful people at Enchroma should have earned a 5 star review but I have one peeve. Being sunglasses they should have polarized lens but they don’t and the reflections on the inside of my car’s windshield is very annoying.
