I thought I had grown past clip-ons, but decided to try these out. They definitely make a difference for night time driving and on overcast days - not so much on regular days. As clip-ons, they are a bit of a pain to get on and center, but because they are about the size of regular glasses, only out another 1/4 to 1/2 inch they don't cover my range of side to side vision, so for just forward objects fine, but not so much on the sides. I have a smaller head than most, so I didn't expect this. I'll mostly save them for nighttime and long trips, as they are an improvement for some things. Decent investment - only time will tell on durability.
