Produced at night, melatonin is a hormone which regulates endogenous circadian rhythms and is suppressed by
bright light exposure. The nighttime use of light-emitting devices has been associated with reduced melatonin production and disturbed sleep. Blue light has the most impact on melatonin production and hence on circadian rhythms. This pilot study evaluated whether a specific blue-light-filtering eyewear reduces the impact of bright light exposure on melatonin production.
