Title:
SLEEP-INDUCING WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163101
Kind Code:
A1
Abstract:
A wearable device (1) includes an optical member (2), and a wearable portion (3). The optical member (2) is located in a site of a user's field of view and includes a bandpass filter that, out of the incident ambient light, transmits light of a specific wavelength region which induces sleep. The bandpass filter has a peak wavelength region of 430 to 550 nm, and transmits very narrow band light that has a half-value width of 10 nm or less. Additionally, the bandpass filter has a configuration in which a dielectric multilayer and a color filter are stacked together. The color filter cuts transmitted light of the dielectric multilayer that has shifted to a shorter wavelength depending on the incident angle of the light.
