This article discusses the exposure hazards to eyes/face associated with specific non-ionizing electromagnetic radiation (EMR) not addressed by OSHA: ultraviolet (UV), infrared (IR) and high-energy visible light (HEV).
UV is found in sunlight and is a form of EMR with high frequency waves. The biological effects of UV radiation depend on the wavelengths concerned. The non-ionizing UV spectrum has a wavelength shorter than that of visible light but longer than an X-ray (100 nanometers [nm] to 400nm) and is categorized based on intensity: UV-A (315nm to 400nm), UV-B (280nm to 315nm) and UV-C (100 nm to 280nm).
