SecureFit™ 500 Anti-Fog / Anti-Scratch Coating Safety Glasses, Indoor / Outdoor Light Grey Lens - 

For eye protection designed for comfort, performance and compatibility, select the 3M™ SecureFit™ 500 Series. These contemporary safety glasses feature a sporty streamlined lens shape and weigh just 22g for a sleek, stylish look. 3M's innovative temple design features slotted ribs that provide comfortable pressure equalization, allowing the temples to flex and self-adjust to the size of the wearer's head. The design of these safety glasses applies pressure to the less sensitive back of the head instead of the temples, achieving a comfortable fit even during rapid head movement. The adjustable ratchet temples offer even greater customisation by allowing user to adjust the lens for facial features and eyeglass position. These glasses can combine well with other personal protective equipment.
