REACTIV lenses are made from Trivex®, a next-generation polymer (polyurethane + nitrogen), first developed for the U.S. military, combining cutting-edge science with ultimate performance.
After more than 12 years of development, this material was first applied to fighter jet canopies and helicopter windshields, environments where optical precision and extreme durability were absolutely critical.
Polyurethane and nitrogen are mixed at a precisely controlled ratio and temperature.
The material is injected into a glass mold to form the lens base.
Gradual heat treatment for 7–10 hours between 85°C and 130°C ensures strength and optical stability.
Each lens is demolded, inspected, and tested to meet extreme performance standards.
