Protect your eyes and shine hands-free task lighting right where you need it. COAST SPG500 Lighted Safety Glasses feature a built-in, rechargeable light with a tilt-and-twist optic that transitions seamlessly between flood beam and BULLS-EYE(TM) Spot Beam. Mounted right on the frame, the two-mode light peaks at 1709umens on high or can run for up to 16 hours on low. Designed for use in the toughest work environments, these ANSI impact-tested safety glasses are built to last-featuring premium anti-scratch and anti-fog lenses, including a set of interchangeable yellow lenses to enhance contrast and depth perception in low-light conditions. A comfort-stretch eyewear retainer strap allows you to cinch the glasses in place during use or hang them around your neck. Silicone padding on the nose and temple pieces ensures comfort for long days of work and a snug, secure fit so that the glasses stay on even during high-intensity, active work. The included soft pouch provides an easy solution for protecting the glasses and lenses when not in use.
