I don't know really. The Mark II's had laminated glass, the mark 3 series celluloid, and then the mark IV's laminated glass with split lenses (which became quite a fashion for subsequent goggles).
This is why the mark II's were quite popular with many pilots, as the lenses didn't scratch easily, and didn't distort their vision
