Scientists have come up with a tinted sheet that reacts to volts by quickly changing colors

There are already lenses in the market that can change color when exposed to sunlight. However, shortcomings such as slow transition speeds and the inability to activate behind UV-blocking windshields plague these technologies.

In pursuit of a better way, Anna Österholm, research scientist and the first author of the Four Shades of Brown project, shares:

“…(B)y using electrochromic polymers, we can create devices that by pushing a button, can be converted from dark to clear.”

This development can provide uninterrupted comfort for people who often shift between bright and dark environments such as pilots and drivers. Clip-ons or a separate tinted pair should be unnecessary with the new tech.
