Summary
This introductory overview describes how the eye's photoreceptors — rods, cones, and intrinsically photosensitive retinal ganglion cells (ipRGCs) — capture and process light, with implications for understanding circadian and visual responses to lighting. Lighting designers can use this foundational knowledge to better understand how spectral composition of light affects both visual performance and non-visual (circadian) outcomes.
Categories
The Science of Light: Introduces ipRGC, rod, and cone photoreceptor biology and spectral sensitivity relevant to lighting standards.
Eye Health & Vision: Covers the structure and function of the visual system including retinal photoreceptors.
