These space-age-looking glasses soak up rays while protecting users’ eyes from them. The solar juice they collect can be used to power iPods and similar gadgets while out at the beach, the ballpark and a thousand other places, more or less.

As it says at Yanko Design:

The dye solar cell is described by the designers of the SIG as “cheap organic dye [used with] nano technology [providing] cheap but high energy efficiency.” Inexpensive, light, and visible-ray penetrable. The lens turns sunlight rays, (rays that would otherwise harm the eye,) into electrical energy.
