Smart Sunglasses

Here’s a candidate for the next big thing: A pair of glasses with lenses that can be transparent or dark, and in shades of yellow, green or purple, all basically at the push of a button. Chemists at the University of Washington in Seattle say they are developing ‘smart’ sunglasses that will let the wearer instantly change the color of their lenses to virtually any hue of the rainbow.

Now this is cool science! The sunglasses are powered by a watch battery and by turning the dial, it alters the voltage to affect the layers and change the color or transparency. Neat stuff.
