Blue-light-filtering eyewear and circadian lighting reduce or shift the short-wavelength (blue) light that most strongly signals the brain's master clock. Daytime lenses cut glare and strain; evening amber and red lenses and low-blue lamps protect night-time melatonin.
Mistimed light — especially blue-enriched light in the evening — suppresses melatonin and disrupts the circadian rhythm that orchestrates metabolism, hormone release and sleep. Managing light exposure by time of day helps preserve the circadian signalling that underpins long-term metabolic and cognitive health.

“Findings suggest that mistimed light exposure, including evening blue-enriched light, disrupts the human circadian rhythm and melatonin signalling.”
“Both short and long sleep duration were associated with an increased risk of all-cause mortality in this meta-analysis.”
“light in the evening can suppress melatonin secretion and disturb deep sleep”
