Quantifying irradiance for eye-mediated non-image-forming effects of light in humans Ingestion-build-251241What is PD CEN TR 16791 Irradiance for eye mediated non image forming effects about? PD CEN TR 16791 is a safety standard on quantifying irradiance for eye mediated non image forming effects of light in humans. PD CEN TR 16791 proposes metrics that can be used to evaluate and compare lighting conditions with respect to their potential to achieve non image forming, eye mediated effects of light in human beings. PD CEN TR 16791 applies to visible optic
