ALTALIST KAKU SP1 Photochromic Lenses (Smoke Gray Frame, Blue Mirror Lens)

Featuring large lenses with a wide field of view and excellent wind and dust resistance. The photochromic lenses change color depending on the amount of UV rays, making them suitable for day or night use. The lenses are made of polycarbonate (PC), which offers high impact resistance and transparency. The frames are made of Grilamid TR-90, a lightweight material said to be a new material for the 21st century, with excellent elasticity and impact resistance. Air vents on the temples, which also aim to reduce weight, improve air circulation and reduce lens fogging. This Asian-fit product was designed by a Japanese designer, with a gentle curve on the front and a wide frame to fit the Japanese skeleton, which has a wide face and low nose bridge. The adjustable nose pads allow for easy adjustment of the distance from the cheekbones and forehead. Silicone is used in the areas that come into contact with the ears to prevent pain. The full frame ensures strength and safety. Includes an inner frame for prescription lenses.
