Disability glare

Since the development of the original Holladay-Stiles formula for the equivalent veiling luminance, L (sub)seq, due to a glare source, a number of papers have been published with refinements to this equation based on psycho-physical measurements. For the most part, these measurements were made for glare angles larger than 2 degrees. Data for smaller angles was hard to obtain and results varied considerably from one paper to another. In this paper, we present a formula based on objective measurements, to determine L (sub)seq. Additionally, the equation is modified to include background luminance and age as parameters.
