Attenuation of short wavelengths alters sleep and the ipRGC pupil response
ConclusionsThe use of short wavelength‐blocking glasses at night increased subjectively measured sleep quality and objectively measured melatonin levels and sleep duration, presumably as a result of decreased night‐time stimulation of ipRGCs. Alterations in the ipRGC‐driven pupil response suggest a shift in circadian phase. Results suggest that minimising short wavelength light following sunset may help in regulating sleep patterns.
