Light and health

The health risks associated with exposure to visible light are well known in the case of, for example, prolonged exposure to intense radiation sources (arc welding without eye protection, gazing directly at the sun without the appropriate sunglasses, etc.).  The development of new light sources (LED) or new technologies (3D) currently raises the question of their impact on eyesight, especially for those who are most vulnerable, such as children, and in particular during the period when eyesight is in the development phase, as well as issues relating to long-term consequences. See the Agency’s work in this area.
