UK: Firm developing active optics to block laser light, for use in glasses and visors

Folium Optics, a firm from Thornbury near Bristol, is developing an anti-laser shield consisting of two thin layers of plastic containing liquid crystals. When laser light is detected, the shield acts as a shutter to block the detected wavelength, while still giving good visibility to other colors.

It can be integrated into visors, goggles or other eyewear. Below is an “early prototype” showing detectors above the nose bridge and batteries on one earpiece:

They began work on the “laser dazzle visor” in 2014 and hope to start selling to military, airline suppliers and emergency services in 2018.
