It is also lightweight and extremely impact-resistant. The lenses feature 3 superb elements, which maximize the transmission of the colors your eyes see naturally. The result is visual acuity, contrast, and color that are unrivaled. It blocks 100% of harmful UVA and UVB rays. It also has Anti-Reflective coating which is a violet-colored coating on the back of a lens that prevents sunlight from coming in from behind and reflecting off the back of the lens into the eyes. This coating is most useful on water or snow. On the front of the lens, we have a Flash Mirror coating for additional filtration.
