Skullerz OSMIN Anti-Scratch and Enhanced Anti-Fog Safety Glasses feature an Over-the-Glasses (OTG) wraparound lens for a wide field of vision and seamless fit over prescription frames. These safety glasses feature tough anti-scratch and anti-fog polycarbonate lenses to protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. The frame features a nylon and soft rubber design for added durability and flexibility, while a molded-in brow guard and side shields provide enhanced protection from debris. Integrated brow venting enables airflow for improved anti-fog performance. To provide a custom, secure fit on a variety of faces, the rubber temples can be easily bent and re-bent. Built-in soft rubber guards on the frame and temples protect prescription frames and lenses from constant movement and harmful scratching that can occur with some over-the-glasses safety glasses.
