Moderate and high-power direct laser beam or the reflected beam will damage eyes and skin, even cause quite serious damage. Do you want to live in that world? Obviously, the answer is no. Here I'm very pleased to recommend this Laser Safety Goggles for 200-450nm and 800-2000nm (RD-5). This is a new style of laser protection glasses. The Laser Safety Goggles is made of durable and high quality resin material. The 200-450 and 800-2000nm laser beam dot is clearly visible. Ergonomic design makes the 2000nm Laser Safety Goggles comfortable to wear. This Laser Safety Eyewear is ideal choice for laser experiments and many other laser applications. According to the optical properties, the same lens can also protect multiple color lasers. The Laser Safety Glasses come with anti-laser, anti-infrared, anti-Helium-Neon functions.
