These are the safety glasses that passed a v0 ballistic test for impact—required by the U.S. Army’s Authorized Protective Eyewear List—and meets the ANSI Z87 standard for eye protection. The glasses’ frames come with two sets of interchangeable lenses (one gray; one clear) treated to resist scratching and fogging while blocking 99.9% of UV-A and UV-B light. Their adjustable temple length provides a customized fit and their three-position ratchet lens inclination adjusts to provide unsurpassed extended wear comfort. Soft flexible fingers adjust and conform to almost any nasal profile to reduce slippage and improve fit, a soft elastomer brow guard diffuses and deflects impact and provides unparalleled comfort, and a unique ventilation channel between the frame and lens vents the eye socket area for moisture and fog control. With nylon case, belt loops, lanyard, and cleaning cloth. One size.
