3M™ Nuvo™ reader protective eyewear features built-in magnifying diopters on the lower lenses to provides eye safety to workers who have difficulty reading small print or seeing small detail work. Characteristic of the Nuvo™ line, these glasses feature a distinct, nostalgic look with reliable eye protection that includes an integral brow bar and side shields for added coverage. The glasses appear to have a dual lens to make them look like standard glasses, but the lens is really a one-piece design for extra durability. The impact-resistant polycarbonate lens absorbs 99.9% UV rays. To enhance comfort, these safety glasses come with a soft nose bridge to cushion a high contact point. These safety glasses are recommended for the following tasks: chipping, chiseling, drilling, grinding, machining, masonry, pouring/casting, power fastening, riveting, sanding and sawing.
