We sought out to find the best sunglass lenses available to pair with the high quality, handmade frames that are RAEN. It was an easy decision to go with Optics by Carl Zeiss Vision. Carl Zeiss is based in Italy, and is a global leader and pioneer of the world’s finest camera glass, precision microscope optics, sun lenses and more.

All RAEN sunglasses are outfitted with Carl Zeiss Vision CR-39 Lenses and CR-39 Polarized Lenses for a perfect pairing of eye protection, optical quality and timeless style. CR-39 is a material that is almost entirely opaque in the ultraviolet range and transparent in the visible spectrum. RAEN’s Optics by Carl Zeiss CR-39 lenses have a scratch resistant coating making them the superior material for prescription and sunglass lenses. CR-39 lenses provide 100% UVA / UVB protection and can sustain continuous use in temperatures up to 100 °C and up to one hour in 130 °C. They are also resistant to gamma radiation, material fatigue, aging and most chemicals. RAEN’s CR-39 Polarized lenses reduce glare from the ocean surface, car hoods and other reflective surfaces ensuring you clear vision in all of the activities you incorporate into your daily lifestyle.
