Overview
Chisel work throws fragments. Grinding throws them faster. And every one of those operations also produces fine dust that will find its way into an unsealed eye. The right choice is a pair of sealed goggles with indirect ventilation: they stop both the impact and the dust, which ordinary safety glasses do not.
Using it
- Wear them from the moment you pick up a chisel, not from the moment you start cutting.
- Anti-fog coating matters in a damp workshop. Fogged goggles get taken off, and that is when injuries happen.
- Keep a spare pair. The reason people stop wearing eye protection is that theirs are unusable.
- Dust gets in through the top and the sides. Sealed frames with indirect vents are the only real answer.
Safety notes
- Scratched lenses reduce vision, which is itself a hazard. Replace them.
- Ordinary glasses and sunglasses are not impact rated and offer essentially no protection.
- For bush hammering and pneumatic tools, add a full face shield over the goggles.
