SOUNDVISION's FullPro eye protection was designed specifically for use with earmuffs and headsets, offering an advantage to regular safety glasses that have arms that break muff seals, causing pressure points against the skull and reduce protection by 3-7 decibels. FullPro attaches to the outer surface of earmuffs using a velcro-like strap to preserve full and comfortable protection and is compatible with most popular brands of earmuffs and headsets. It also meets ANSI's Z87.1+high impact safety rating.
