Wondering how dark our sunglasses are? Or what is the best lens darkness category to protect your eyes from the sun? All ro•sham•bo baby sunglasses lenses are Category 3 in terms of darkness, which falls into line with the European standard for UV protective sunglasses and also meet regulated United States safety standards. All of our sunglasses also have polarized lenses, which provides 100% protection against UVA, UVB and UVC rays.
