As a sufferer of both poor eyesight and my current ugly frames, I've developed a bit of a fixation with Prism optics. The style below is 'Rio' is cream tortoiseshell and is high up on the wishlist this week. With frames named after the world's most brilliant cities - Rio, New York, London, Paris, Rome - Prism provide a great alternative to the old trend of overly blinged-out designer frames (hello Chanel). Unfortunately for us, they are only available through Dover Street Market & Browns in London, and Barneys in NY. On the other hand, what better souvenir to pick up from your favourite international destination? You can see the range for yourself at http://www.prismlondon.com/.
