"Improving Population Visual Assessments requires a Melanopic Based Augmentation to Light Meters"

Melanopsin signals have been associated with light driven circadian entrainment, pupil size changes, and clinical assessments for conditions such as SAD and photophobia. However, these signals have a much broader influence on vision in that they can affect any visual assessment based on light level and where spatial brightness perception, rather than object brightness, is a component. The study determines the quantitative augmentation required to assure that light meters provide a veridical assessment of light quantity consistent with perceptions of brightness.
