Abstract

CIE 191:2010 recommends a mesopic photometry system based on peripheral visual tasks. For implementation of the system, the visual adaptation field needs to be defined, taking into account the surrounding luminance effect on the adaptation state. A series of vision experiments in the mesopic range has been conducted to measure the surrounding luminance effect with respect to the angle between a peripheral task point and a point source (glare source). The results show that the surrounding luminance effect at the peripheral task point decreases with the angle at a larger slope than existing models, such as Stiles-Holladay equation, CIE general disability glare formula, and Stiles-Crawford equation. Thus, a new model for the surrounding luminance effect has been developed and proposed from the results
