A STUDY OF THE SUSTAINED PUPIL RESPONSE UNDER A VARIETY OF LED ILLUMINATIONS

Résumé

The sustained pupil response of 9 observers has been recorded after 5 minutes adaptation to 5 spectrally different lights, at 100 and 210 lx. Warm white and Cool white commercial illuminations, and three metameric illuminations: incandescent light and two colour LED associations have been used. When the spectral power distribution of the light is strongly imbalanced with depletion around 480 nm, the selectivity of the pupil response, possibly due to weak excitation of the melanopsin retinal ganglion cells.
