CIE Considers the "Good and Bad" of Light

Description

Light, and the wider optical radiation spectrum (ultraviolet and infrared radiation), provides us with many benefits. However, too much may be harmful and too little may mean we cannot carry out our daily activities, or may indeed compromise our well-being. Division 6 of CIE, Photobiology and Photochemistry, is responsible for developing action spectra for the effects of optical radiation on people, as well as flora and fauna. John O'Hagan, Luke Price and Luc Schlangen, respectively, Division 6 director, Division 6 secretary and chair of the Joint Technical Committee (JTC) 9, explain the work done to determine the balance between risk and benefit from exposure to optical radiation
