I'm very impressed with Suncloud sunglasses.  I bought the first pair last spring and wore them all summer in Phoenix. When I discovered they sell bifocal readers I was thrilled.  There is no glare, are nice and dark. and they fit nicely around my face.  Now I can see close up too!  You can't see the bifocal line on the side of the glasses that faces people, only on the inside.  Living in Phoenix good sunglasses are a must, and these work great.
