Blue Light Blocking

Meaning

Blue light blocking refers to the use of specialized lenses or filters to mitigate the exposure of the eyes to high-energy visible (HEV) light, primarily emitted by digital screens and modern lighting. From an endocrinological perspective, this practice is a key component of circadian rhythm management, specifically targeting the suppression of melatonin secretion. The goal is to minimize the disruption of the body’s master biological clock, the suprachiasmatic nucleus (SCN), which is highly sensitive to blue light wavelengths.
