Since one-size-fits-all usually leaves out a few people, the smaller StarLite-SM safety eyewear has been specially designed for smaller, narrower faces. This version is 10% smaller than the classic StarLite models, but still provides exceptional impact protection, durability, superior optical quality, and a fashionable design. Its scratch-resistant polycarbonate lenses, which are available in clear, gray, clear anti-fog, and mirror finish, filter out more than 99.9% of harmful UV-A and UV-B rays.
