Eyewear 1 includes an eye shield 2 of a mesh 3 of hexagonal apertures chemically etched through a thin sheet of stainless steel or plastics material. A safety visor including an eye/face shield of a mesh with hexagonal apertures etched in a thin sheet of stainless steel material is described in NZ 515436 for example, but the etching is not disclosed in the earlier published document to be "chemical" as claimed in this application.
