These high-quality safety glasses feature a built-in bifocal lens, so they provide effective magnification as well as top-level eye protection. The shatterproof polycarbonate lenses conform to ANSI Z87.1 specifications for high-impact protection and also offer UV400 protection; the bifocal delivers 3.0 diopter magnification (+3.0 reading power). The comfortable, durable glasses are ideal protection when operating power tools as well as useful for executing close-up work; you can also wear them with an OptiVISOR to increase magnification even further.
