Summary
This entry references the role of visible light — particularly the blue spectrum at 480 nm — in stimulating intrinsically photosensitive retinal ganglion cells (ipRGCs), which are central to circadian entrainment. Practical lighting design should account for the spectral composition of light sources, especially the blue wavelength range, to effectively influence circadian biology.
Key Findings
- Blue light at ~480 nm provides specific stimulation to ipRGCs (intrinsically photosensitive retinal ganglion cells) in the retina
Categories
The Science of Light: Discusses ipRGCs and the specific blue light spectrum (~480 nm) stimulus relevant to photoreceptor biology and circadian photoentrainment.
