Greg Sotzing’s work with transition lenses for sunglasses is getting the attention of the military, which is interested in his technology to make lenses change colors almost instantaneously.
Most transition lenses use polymers that darken when light hits them. The new technology developed by Sotzing and his colleagues uses an electric current that changes the lenses’ colors when triggered by light.
Military officials are interested because it could help troops avoid the need to change lenses in their goggles, such as when they emerge from indoors to blazing desert light.
Sotzing, a member of University of Connecticut Polymer Program, starts a one-year sabbatical next month at the Air Force Academy to work on the ideas.
