Skullerz BALDR Anti-Scratch and Enhanced Anti-Fog Safety Glasses feature a full-frame design and non-slip rubber temples to keep glasses secure, while also resisting sweat. 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. Available in a variety of lenses to suit a range of tasks and light environments. The durable frames bend and flex without breaking. The integrated accessory receptors at each temple also improve airflow when not in use. For added safety, an elastic retainer strap or foam gasket insert (both sold separately) can be attached to the temples.
