AI Technical Summary

Technical Problem

Modern artificial lighting, particularly from blue LEDs and fluorescent lamps, disrupts the human circadian rhythm and retinal physiology due to its high energy and inappropriate wavelength emission, leading to issues such as sleep disorders, eye strain, and health problems, while existing 'anti-blue light' solutions are ineffective as they fail to target the correct wavelengths and are not adjustable.

Method used

An optical device that filters blue, green, yellow, and orange light, particularly for eyeglasses, designed to block the peak sensitivity wavelengths of 450-480 nm emitted by artificial light sources while allowing beneficial natural light spectra, ensuring adaptability based on lighting conditions.

Benefits of technology

The device effectively mitigates the disruptive effects of artificial lighting on the circadian rhythm and retinal health by selectively filtering harmful wavelengths, promoting physiological balance and improving sleep quality and overall well-being.

Abstract

Optical device filtering blue, green, yellow, and orange light, particularly for eyeglasses. Optical device, with or without visual correction, comprising at least one light-blocking device under standard transmittance study conditions (ISO 8980-3, ISO 12312-1:2013, ISO 12312-1, ISO 9050) and with a reference light source conforming to the white light standards defined by the International Commission on Illumination, such that: more than 76% of the light is blocked in the wavelength range of 380 to 500 nanometers or more than 41% of the light is blocked in the range of 500 to 650 nanometers. This filtering is achieved using a dielectric multilayer coating or at least one absorbing, reflective, or interfering material.The device is intended for use only during the physiological nighttime periods outside of the user's sleep, as defined in the description, and for numerous physiological benefits, also indicated in the description.
