ALTALIST KAKU SP1 SP Photochromic Lenses Gray Gray Mirror [ALTALIST] (Kaku One) (Smoke Frame, Lens)

It features a large lens that offers a wide field of view and high wind and dust resistance. These photochromic lenses, whose tint changes depending on the amount of UV light, can be used day or night. The lens material used is polycarbonate (PC), which has high impact resistance and transparency. The frame uses "Grilamid TR-90," a new material of the 21st century that is highly elastic, impact-resistant, and lightweight. The air vents in the temples, which also serve to reduce weight, improve air circulation and reduce lens fogging. Designed by a Japanese designer, these Asian-fit products feature a gentler curve at the front and a wider frame width to better suit the facial structure of Japanese people, who tend to have wider faces and lower nose bridges. The adjustable nose pads allow you to freely adjust the fit between the mask and your cheekbones and forehead. The parts that touch your ears are made of silicone to prevent pain. The adoption of a full frame ensures strength and safety. Includes inner frame for prescription lenses. About ALTALIST
