Like all these polarized products, I find the vision is not clear.  The only time it improved my vision at night was when there was no oncoming traffic.  Did reduce glare of lights, but that caused my side of the road to look darker than if I weren't wearing them at all.  I'm hoping they'll work better on the lake when I go fishing and have the sun glaring off the water.  For the price, it's not a bad pair of glasses, but be prepared for a long wait to get them from overseas.
