Mixed results. Got these to
"Mixed results. Got these to eliminate nighttime driving issues with headlight glare. The Yukons give a slight improvement on that issue. The AMOUNT of glare IS NOT REALLY reduced but somehow seems to be GENTLER, hard to explain. But the glasses do help, if only a wee bit. Now I used them on a dull overcast day and they were gret in brightening my view and introducing very noticeable and helpful contrast as well. So I did not order them for the daylight vision improvement but it is so useful that I am keeping them. As I got a pair of glasses, I gave the other set to my wife and she registewred the same results and opinion as I did. No miracles here with the nighttime glare reduction but a slight improvement that is detectable and useful. Great for dull overcast or foggy days, as noted above."
