How Visible Light And Blue Spectrum Work
- Visible light spans ~380–750 nm and each wavelength maps to a color our eyes detect.
- Daylight is rich in blue wavelengths and high lux, which cues our circadian rhythm.
Blue Light As A Daytime Signal
- Daytime sunlight is high in blue light and brightness, while night light is low in blue and lux.
- Our brain uses both total brightness and blue content to tell day from night and regulate circadian rhythms.
Don't Block Blue Light In Daytime
- Avoid wearing blue-blocking glasses during the day because blue light helps regulate your circadian rhythm.
- Seek natural morning light to improve sleep and circadian regulation.
