Summary
This review examines how short-duration exposure to short-wavelength (blue) light affects cognitive performance, with a focus on the role of intrinsically photosensitive retinal ganglion cells (ipRGCs) discovered in 2002. Practical implications suggest that targeted blue light exposure could be leveraged in lighting design to modulate alertness and cognitive function in workplaces and healthcare settings.
