Ocular Photobiology

Meaning

The specialized field of study focused on the physiological and biochemical effects of light on the eye, particularly the non-visual pathways that regulate the body’s circadian rhythm and hormonal systems. This discipline investigates how light’s intensity, duration, and Spectral Quality Requirement are transduced by the intrinsically photosensitive Retinal Ganglion Cells (ipRGCs). Ocular Photobiology provides the foundational understanding for clinical light protocols, establishing the link between environmental light exposure and systemic physiological state anchoring. It is essential for optimizing chronobiological interventions.
