NXT® Performance
Originally created to serve as the bulletproof windshield material for US military aircraft, NXT is a polyurethane material characterized by high impact resistance, light weight, superior optical qualities, resistance to chemical contamination and exceptional performance as a medium for photochromic (light-sensitive) dyes. NXT is the most advanced photochromic sun lens material ever made, creating lenses like our 24:7 with a broad transmission range, rapid activation and exceptional durability. NXT is so strong, lenses made from it are guaranteed for life against breakage.

Guaranteed Unbreakable for Life
NXT® is stronger than any lens material, guaranteed not to break or crack. The NXT® lifetime guarantee of unbreakability, not only provides safety and protection to the end user, but also sets a new standard of quality and reliability.
Outstanding Optical Properties
NXT® has a lower refractive index (produces less surface reflection and rainbow effects) and higher Abbe number (focuses colors more sharply) than polycarbonate. Images are clear and better defined.
Lightweight NXT® is about 12% lighter than CR-39® and 10% lighter than polycarbonate.
Impact Resistance
NXT®’s impact resistance is higher than polycarbonate and passes all impact resistance standards.
Superior Anti-Scratch Properties
NXT™ lenses feature a superior Quarz™ scratch-resistant antistatic coating, which doesn’t attract dust.
No Stress Cracking or Crazing
Unlike polycarbonate and other materials, NXT® is not sensitive to stress cracking, so it does not craze or break when subjected to mechanical strains.
Processed by Casting
Lenses in NXT® are made by casting, which ensures low internal stress, high optical homogeneity, thermal and mechanical stability.
High Chemical Resistance
Unlike polycarbonate and polyamide, NXT® is not attacked by common chemicals or solvents (i.e. acetone and methyl alcohol).
