All Zenni Optical eyeglasses come with Anti-Scratch Coating and UV Protection Coating that are both absolutely free. We also offer Anti-Reflective (also known as Anti-Glare) Coatings, which reduce reflection on the lenses and the glare you see while you are wearing your glasses.
Our Blokz™ , blue blocker lens technology is not a coating, but in fact a blue-light blocking polymer from Mitsui Chemicals, a leading lens material manufacturer. This polymer is directly incorporated into the lens materials. That means the blue blocker lens technology won't chip or wear away.
