Safety Goggles with Adjustable Strap

Safety goggles with an adjustable head strap. The strap is what separates goggles from safety spectacles: they sit tight against the face and stay put when you look down, lean into a cut or work overhead, and they seal round the eye rather than leaving the gaps at the sides and brow that let dust and chips in. That makes them the right choice for grinding and cutting, chasing walls, drilling overhead, chipping and demolition, spraying, and handling chemicals or cement dust. The strap adjusts to fit over a cap or under a helmet and to suit different heads, which matters where goggles are shared between a crew. Replace them once the lens is scratched enough to distort vision - people push scratched goggles up onto their forehead, and then they protect nothing.
