Report on the Workshop Use and Application of the new CIE s 026/e:2018, Metrology for ipRGC-influenced responses to light “specifying light for its eye-mediated non-visual effects in humans”

In December 2018, the international standard CIE S 026/E:2018 “CIE System for Metrology of Optical Radiation for ipRGC-Influenced Responses to Light” (doi.org/10.25039/S026.2018) was published. This standard defines spectral sensitivity functions, quantities and metrics to describe the ability of optical radiation to stimulate each of the five retinal photoreceptor classes that can contribute, via the melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs), to the retinally mediated non-visual effects of light in humans. This one-hour workshop started with four 10 minute presentations about the standard, followed by a general discussion and questions. The four presentations focused on the following topics:
1) Introduction to CIE S 026 and its quantities (Luc Schlangen)
2) Demonstration of toolkit (in preparation) to calculate CIE S 026 quantities (Presented by Luc Schlangen on behalf of Luke Price)
3) Accounting for field of view (David Sliney)
4) ipRGCs and pupil response (Manuel Spitschan)
