The scratch-resistant anti fog polycarbonate lens of these wrap around spectacles is designed to British Standard EN166 1F, meaning it can survive the impact of a 6mm steel ball travelling at 45m/s. These spectacles are suitable for drilling, grinding, hammering and similar tasks. They feature a comfort-fit bridge and adjustable arms for a more secure fitting.
