ALTALIST KAKU SP4 Interchangeable Lens (Black FrameGold Mirror Lens & Clear Photochromic Lens)

Featuring large lenses with a wide field of view and excellent wind and dust resistance. This set includes a clear photochromic lens and a PVD multi-layer color-coated mirror lens. The lenses can be swapped out to suit your environment and needs. The lenses are made of polycarbonate (PC), which offers high impact resistance and transparency. The frames are made of Grilamid TR-90, a new material for the 21st century that is lightweight, shock-resistant, and highly elastic. Designed by a Japanese designer, this Asian-fit product features a gentle curve at the front and a wide frame to fit the Japanese frame's wide face and low nose bridge. Three interchangeable nose pads—high, medium, and low—allow you to adjust the fit to your cheekbones and the distance from your forehead. Silicone is used in the areas that come into contact with your ears to prevent pain. Includes an inner frame for prescription lenses.
