Amazing! UNIQBROW lenses are organic CR-39 Truecolor lenses, including a category 3 UV 400 protection filter that protects from 100% UVA/UVB Rays and are certified by the European Union. Our lenses are manufactured with the most advanced AntiScratch treatment technology which provides the lens surface with a layer of protective film and improves its resistance to heat, humidity, knocks, and scratches. Its oil-resistant overlay provides softness and makes it harder for any dirt to stick, while also guaranteeing resistance to water, oil, and perspiration stains, which can be cleaned easily without leaving any marks.
