As a mature person who struggles with the dazzle from the modern car led headlights I do wonder why I did I not get these years ago. Been really struggling with glare from headlights when driving on unlit rural roads . These glasses make that so much easier and less blinding on the eye, they don't totally eliminate the glare, but it's reduced drastically and I feel safer driving at night now. The glasses are good quality and they come with a really nice case, cleaning cloth and screwdriver to adjust for.. absolutely great value for the money. Very pleased with my purchase,
