The Coast Products SPG500 Rechargeable Bulls-Eye Spot Safety Glasses feature a built-in high/low spot beam on the frame for improved up-close and long-range sight. The rechargeable eyewear shines up to 13 hours on a single charge (charging cable included). For added control, the light operates in high or low mode while keeping user's hands free and increasing on-the-job safety. The glasses are ANSI-tested for impact resistance and offers anti-scratch and anti-fog lenses, including a set of interchangeable yellow lenses to enhance contrast and depth perception in low-light conditions. They also have padding on the nose and temple for comfort and a snug, secure fit.
