1.7 (43.2% to 58.1%)
Lens markings are usually made up of four standards, one of which includes Light Transmission. This particular range of products includes protective eyewear with a 1.7 light transmission marking, which means that these lenses allow from 43.2% to 58.1% of light to pass through. Lenses with low levels of light transmission are ideal for use in very bright environments.
