Most good night driving glasses have two coating, one is the yellow tint, the second is a Zeis coating like what is on a set of binoculars which very efficiently block the glare you get from oncoming bright lights. My night drivers were fairly expensive at about 325 buck but there isn't any other set that I have ever had that equaled them for blocking the bright and glare of oncoming headlights. they also work great seeing in a heavy downpour, you wouldn't think they would help but they are excellent for that also.
