Smart Sunglasses Allow Color Change

Newly designed “smart” sunglasses can change from transparent to dark or shades of purple, green or yellow with the touch of a button. Developed by researchers at the University of Washington, the prototype utilizes an organic oxide to create a new material that can block up to 95% of UV rays. The glasses were designed for construction workers, athletes or anyone with sensitive eyes.

“These lenses are more active, more intelligent, than today’s sunglasses” said University Professor Chunye Xu. “But because of the materials we’re using we don’t think the price is going to be very different.”

Although photochromic lenses are already available that darken in response to light, the user cannot adjust its shade. Look for the real thing to be on the market after a couple more years of research.
