Our Blue light filtering glasses are designed to reduce UV rays and filter light from digital devices natural and artificial sources (screens, LEDs, digital devices, etc.), with the sun being the biggest source of blue light. Some studies suggest that exposure to blue light may cause discomfort. Blue light Glasses may reduce discomfort associated with exposure to blue light.
Blue-violet light is between 400 and 455nm as stated by ISO TR20772-2018.
