Oh my word. These are fantastic. I really can't believe the simplicity. My regular glasses are reactions so in the car they are clear. Just pop these sunglasses over top and you're good to go. Because they are polarised the reduction of glare is very noticeable compared to regular sunglasses. I ordered 2 pairs, one for the car & one for home. At less than £14 a pair I think these are an absolute bargain.i can't stop telling people about them!
