Our Crystal model is engineered to wear comfortably over most prescription eyeglasses, making these safety glasses over eyeglasses a practical, low-profile alternative to bulky safety goggles. The ergonomic wrap-around lens and universal-fit temples provide a snug, secure, slip-resistant fit for men, women, teens, and older children. Deep side temples eliminate the need for separate side shields by providing equivalent 180° brow and peripheral protection built directly into the frame, light enough to forget you're wearing them, which means better safety compliance across your entire team or classroom. These protective glasses exceed ANSI Z87.1 standards for impact resistance and scratch resistance. This is embossed directly on the temple, not just claimed on a label. The clear polycarbonate lens includes an anti-scratch coating that maintains optical clarity over time. No distortion, no compromises, ideal for precision work environments including lab, dental, chemical, and industrial settings. Trusted protective eyewear for construction PPE, industrial eye protection, lab goggles, science class, woodworking, lawn care, weed trimming, shooting range use, and gun range eye protection. Safety glasses for men and women equally, universal fit, consistent protection. Also popular for foam dart blaster parties and school events where eye protection is required. One size fits most adults and older children, a dependable ANSI-compliant solution wherever flying particles are a concern. Each case includes 6 pairs of identical clear-lens Crystal safety glasses, enough to outfit a crew, stock a supply room, or keep a classroom covered for the semester. This is the bulk safety glasses solution for schools, contractors, facilities managers, medical and dental offices, and anyone who goes through PPE regularly.
