New Discoveries in Vision Affect Lighting Practice

Eye health: The paper discusses the discovery of a new retinal photo-sensing receptor, melanopsin, and its role in non-imaging vision functions such as circadian regulation and pupil size variation.

Lighting Design Considerations: The paper explores how the discovery of the new receptor impacts lighting practice, particularly in terms of brightness perception and visual performance, and suggests that lighting design should consider the new receptor for a more visually efficient and energy efficient lighting economy.

Hormone regulation: The paper references studies of the light driven spectral response of melatonin, the hormone regulating circadian rhythms, in relation to the new retinal receptor.
