What can you do with your sunglasses when the Sun goes down? You can use them to charge your smartphone!
An Indian designer based in the US has turned a pair of sunglasses into a smartphone charging device by adding solar panels to them.
Sayalee Kaluskar's The Ray-Ban Shama Shades are part of a project at Miami Ad School - San Francisco, CNET reported.
The shades have a small solar panel on each arm, and that's apparently enough to charge a smartphone when the Sun goes down.
According to PSFK.com, Kaluskar placed small solar panels on each side of the frame, allowing the sunglasses to harness solar energy during the day.
