Fast color-changing liquid may lead to better sunglasses

Researchers in Japan have developed a "photochromic" material that changes color thousands of times faster than conventional materials when exposed to light.

This development could lead to a wide range of new products including improved sunglasses, more powerful computers, dynamic holograms, and better medicines.

The unique photochromic material shows instantaneous coloration upon exposure to ultraviolet light and its disappearance happens within the same short period when the light is turned off. The material is also more stable and longer-lasting.
