High-refractive-index lenses: High-refractive-index materials make lenses lighter and thinner. The high refractive index causes the light to deflect at the surface of the lens, so the thickness of the lens is thinner. The refractive index of the lens is the optical thickness of the surface lens material. The thicker the optical thickness, the slower the light passes through the lens and the greater the deflection of the surface luminosity. Therefore, the high refractive index lens has a stronger refractive power. When the diopter exceeds 4D, it is recommended to use the lens.   Color-changing lens: The color-changing lens is a special lens for the display, which is the best protection against glare. The lenses are available in grey or brown lenses with a coloration rate of 15% to 75%. The light transmission properties of all color-changing lenses comply with the EN172 standard. Shading filters with a light transmission of less than 80% are not suitable for use at dawn, dusk or night.   Ordinary lenses:   Transparent lens: High-impact anti-shock performance with 100% UV protection. Comply with EN166 and EN170 standards.   Amber lens: High-impact shock-proof with 100% UV protection, light yellow filters blue light in visible light and improves contrast. Comply with EN166 and EN170 standards.   Light amber lens: High-impact anti-shock capability with 100% UV protection for a comfortable eye. Improves contrast, especially for short-band beam ranges. Comply with EN166 and EN170 standards.   Gray lens: High-impact anti-shock performance with 100% UV protection. Filters some of the light in the visible light to provide strong light and glare protection. The gray lens is a sunglasses lens that can filter the strong sunlight and does not affect the recognition of bright colors. Comply with EN166 and EN170 standards.   Brown lens: High-impact anti-shock capability with 100% UV protection. Filters part of the visible light beam, blue light and infrared light. Provides glare protection and adds universal protection. The brown lens is a sunglasses lens that filters out the strong sunlight and does not affect the recognition of bright colors, in accordance with EN166 and EN170 standards.   Orange lens: High-impact anti-shock performance with 100% UV protection to filter visible light short-wavelength to improve contrast. Warm-colored lenses protect workers' glasses and can be worn for long periods of time.   UV Green Lens: High-impact anti-shock performance with 100% UV protection to filter part of the visible light beam, providing glare protection in accordance with EN166 and EN170 standards. Blue lens: It has high-impact anti-shock performance and 100% UV protection. The light blue color is comfortable and relaxed. It is especially suitable for some workplaces where eye requirements are concentrated, such as: testing , color proofreading, in line with EN166 and EN170 standards.   Weld Green Lens: Filters all beams produced by gas welding, such as UV beams, IR beams, and visible glare. The level of protection is determined by the different work environments. All welded lenses are made of polycarbonate and the outer layer is coated. Compared with glass lenses and coated lenses, it has better impact resistance, which minimizes the risk of welding sparks and complies with EN166 and EN170 standards.   Yongxing Labor Insurance supplies protective glasses that meet national safety standards .
