These frameless safety glasses are the lightest weight safety glasses in the Skullerz Eye Protection line. Featuring polycarbonate lenses, these safety glasses protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. The wrap-around rimless design maximizes a full field of vision, while a soft and adjustable nose piece offers all-day comfort. The flex-fit temples will not slip or pinch and their low-profile, flat design makes them compatible with hearing protection accessories. These safety glasses are dielectric, meaning that they are not made with any metal parts or pieces, making them non-conductive. VORDR impact-resistant safety glasses are tested to ANSI/ISEA Z87.1-2020 High-Velocity Impact Protection and optical requirements which is the US standard for Personal Eye and Face Protection Devices and is listed on the frame (Marks: Z87.1+).
