NXT® lenses were developed for the U.S. Army. Made from low-temperature casting techniques which reduce internal stresses in the material; this improves optical quality, gives excellent transparency, and increases long-term stability.
Zebra® photochromic darkens or lightens as the surrounding brightness changes from 40.7% to 6.6% of the visible light transmission depending on luminous intensity. Wide amplitude in categories 2 to 4, with fast activation speed of 22 to 28 seconds. Antifog treatment reduces fogging. Recommended for mountain biking, trails and climbing.
