NoCry Over Safety Glasses (OTG) protect both your eyes and eyewear for almost $100 less than prescription safety goggles would. No need to have expensive lenses put into your safety glasses or work without clear sight. ANSI Z87.1 and CSA Z94.3 safety certified, OSHA-approved (Z87+ embossed on the frame). | The strong and durable polycarbonate wraparound construction offers a high level of direct eye protection, whilst the side covers protect peripherals. Clear UV 400nm scratch-resistant lenses block 90-100% of harmful UV radiation allowing for outdoor use. No optical distortion. | Comfortably and easily fit over most reading glasses (up to 5.7in wide, up to 1.37in high on the sides and 1.77in high in the center). Soft tips eliminate pressure behind the ears and the extendable arms adjust for small and larger head sizes - fitting men, women and youth. Can also be worn as normal large sized safety glasses. | Designed for woodworking, construction, chemistry or science lab and dental work, or shooting (always double-check the safety requirements of your local shooting range) - anything you’d need PPE eyewear for. | To avoid scratches, make certain that no part of your own prescription lenses are in direct contact with the protective lenses of the OTG safety glasses. When wearing the over specs, always leave a sufficient gap between both pairs of glasses.
