These work pretty well. They're especially effective for the newer "blue" headlights. Good for heavy night traffic. They came with a repair tool, a cleaning cloth, and a soft cloth bag to keep them in. My ophthalmologist told me they can't hurt your eyes, so just try them. Different people have different levels of satisfaction. I have a pair of larger "Buddy Holly" frames (or Rachel Maddow) that are a bit too large for them to fit over. Top to bottom they're a bit over 1-1/2". I've used them with those glasses, but it's not the best. They fit fine over my smaller glasses.
