Spectacles, goggles and face shields
They cover different areas and are not automatically suitable for the same splashes or impacts. Describe particles, liquids, dust and radiation. A face shield is not always a substitute for suitable eye protection.
Earlier and newer references
AFNOR lists EN 166:2001 as superseded. EN ISO 16321 includes general, welding and mesh-protector parts. Keep the standard edition on every document and do not transfer old marking symbols directly to newer ones.
Read the model markings
Check lens, frame, intended use and restrictions in the instructions. Welding or radiation filters depend on the process and exposure, not just visible tint. Check approved combinations with helmets and respirators.
Comfort and care
Mention prescription glasses, wearing time and fogging. Clean and replace damaged components according to instructions. Send workplace requirements and the existing reference to prepare a comparable proposal.
