This paper presents the results of ballistic and. where appropriate, drop-ball tests on the following piano eye protective devices: (i) goggles fitted with polycarbonate, cellulose acetate, gauze and polymethyl methacrylate lenses: (ii) facesbields with cellulose acetate visors: and (iii) several clip-on configurations. The results are discussed separately and arc also presented graphically to permit comparison with earlier similar data for allyl resin and thermally toughened glass. These results suggest the need for a gradation of eye protective devices based on impact resistance. Suitable tests, using a 25 mm diameter steel ball and a 3 mm steel ball are suggested.
