Light Exposure Dosimetry

Meaning

Light Exposure Dosimetry is the clinical and scientific practice of precisely measuring and quantifying the intensity, duration, spectral composition, and timing of light that reaches the retina and skin over a 24-hour period. This rigorous quantification is essential because light is the primary environmental synchronizer of the human circadian rhythm and a potent hormonal modulator. Accurate dosimetry allows for the prescription of specific light exposure protocols to correct physiological asynchrony or optimize hormone secretion.
