New sunglasses will do more than protect your eyes from UV rays - they will also harness power from the sun to top off mobile gadgets.
The sunglasses will be made from a pair of Ray Ban Wayfarer sunglasses that have been fitted with photovoltaic cells on the plastic ear pieces. The cells will collect solar rays to charge a battery embedded in the frame, and the ear pieces can be removed to reveal a microUSB or Lightening connector that can be used to charge an iPhone.
