Abstract
Effect of simultaneous exposure to extremely short pulses of blue and green light on human pupillary constriction.
Highlights
Light has various influences on all species, including humans
Two-way repeated measures Analysis of variance (ANOVA) revealed that the main effects of irradiance and wavelength on percent pupil constriction were significant (F(2, 20) = 14.78, p = 0.000 and F(2, 20) = 10.79, p = 0.001, respectively)
It has been suggested that pupillary constriction is controlled mainly by rods under lower irradiance light exposure and by Intrinsically photosensitive retinal ganglion cell (ipRGC) under higher irradiance light exposure [14, 21, 23, 35]
Summary
Light has various influences on all species, including humans. Humans have been evolving and adapting under such natural light environments. Illumination in the workplace has a great influence on work efficiency and the health of workers [1]. The effects of illumination are classified as visual effects and non-visual or non-image-forming (NIF) effects. A number of studies in the field of physiological anthropology have focused on the NIF effects of illumination on humans [2,3,4,5,6,7,8]
