Evaluation of the spectral distribution of the electromagnetic emissions from a system composed of a hydrogen-oxygen torch and a glass tube, used in the manufacturing of glass rods from which optical fibers are drawn, indicated levels in the visible and infrared portion of the electromagnetic spectrum that necessitated a specific type of eye protection to be worn by employees operating this equipment. Specific eye wear which provided qualities of both being lightweight and reducing transmission of all three major regions of the electromagnetic spectrum (ultra-violet, visible, infrared) were specified.
