The YF-8L series models are standard personal protective face shields that cover your entire face to protect both you and the people working around you. This type of face shield is exceptionally light, weighing in at only 20 g, making it comfortable to wear all day. If you wear prescription glasses, no problem, they are made to fit over them too. The PET shield material has low reflectivity which increases the visibility of the objects you are viewing while diminishing annoying ghost reflections. These face shields have been crafted in Japan by Yamamoto, the experts of optical safety and glassware.
