SAGA Frameless Smoke Lens Safety Glasses feature tough, scratch-resistant lenses that filter 99.9 percent of harmful UVA, UVB and UVC rays to keep your eyes safe in the sun. A sporty, lightweight, frameless design offers a wide field of vision while on the job. Comfortable, nonslip side arms and contoured nose keep glasses securely in place. Flex-fit temples reduce pressure and headaches caused by tight-fitting glasses. Lenses prevent glare for clear sight while outside in bright light. Use glasses during work like construction, carpentry/woodworking, welding or landscaping. They're even great for hobbies like boating, skiing, fishing, hunting/shooting, sports and more. Glasses meet ANSI Z87.1, CSA Z94.3 and EN166 Impact Protection requirements.
