To match our sunglasses with each of our outfit, we would definitely need pairs and pairs of them. But according to the American Chemical Society (ACS), University of Washington scientists have developed a new lens material that can change their color. The key to this eyewear technology is an electro chromic polymer. It has the capability to increase or decrease the levels of darkness and color in the presence of an electric current. All you need to do is push a button on the frame and your glasses will become red, green, orange or any color. Yup! That’s the magic.
However, we will have to wait a couple of years before actually getting these sunglasses. These ’smart’ sunglasses can also be adjusted to block from 55 percent to 95 percent of the incoming rays. This research work was led by Chunye Xu, who is an assistant professor at the University of Washington and even an associate director of the University’s Center for Intelligent Materials and Systems (CIMS), whose research work is mainly concentrated on Electro active Polymers [EAP] and EAP based actuators.
