I am a 76 year old female who still works everyday. I have found in the last few years the headlights of the newer cars are a lot brighter and appear at times to be on bright. This has made it much more difficult to drive at night. I purchased the glasses in hopes they would work to resolve the problem I was having, almost being blinded, and having to slow way down until they passed. This was the biggest surprise of all "They are amazing" they really really work beyond anything I was hoping for. I strongly recommend this wonderful product. They have given me my night time driving back again.
