Few days back I bought ucb subglasses if grey shayes. It is anazing. It has a super built quality with poloroid glasses gives your eyes a complete protection against the sun. The price is cheaper than thise if rayban gkasses and affordable.
Its not only keep your eyes protected from the sun rays but also provide a better vision once you are out in the shade or dark place. Its sits pretty comfortable on your nose with leaving any mark on it.
It gomes in sgades like black, steel grey etc. All in all its been my hest buy incase if shades till date.
