Shape is everything in the world of eyewear, and Ray-Ban clearly knows this with its re-working of timeless forms, leading them to become future classics. Octagonal is the new round, or so the RX6456 glasses show us with their softly angled frames and crystal lenses, with only clear tips contrasting with the slender silver-toned body.
