Smart sunglasses FTW!

Imagine the embarrassment – you step out onto the boardwalk at your nearest beach hangout, looking fly in your shorts and ironic-slogan T-shirt, only to realise that the colour of the lenses in your shades are so last month it’s painful, and everyone is having a good laugh at your major lack of cred. Now breathe in relief, as you discover that this may never be a problem in the future – even if these ‘smart sunglasses’ are being developed for more practical purposes.
