Wanted these bc I knew I had a long drive ahead of me that would include night driving. Headlights from oncoming traffic often make it unpleasant to drive at night (though I am a night owl!) these not only made it comfortable to see (no shining lights in my eyes), but they allowed my eyes to not hurt or get tired!! They are also terrific when you are out during the day and it gets very dark from a storm. I wore them during the day just to see if they would make the day worse, but I found them a good backup if I don't have my sunglasses with me. They helped during the bright day as well! Well made and VERY comfortable! (I have a big head, but small nose, usually things end up hurting my ears or temples) although I knew they were there, they were comfortable.
