"Blue light glasses filter out blue light," says Dr. Craig See, MD, an ophthalmologist at Cleveland Clinic Cole Eye Institute. "They allow the other colors of light to pass through and reach the eye."
The blue light spectrum is an essential part of the visible spectrum with wavelengths of about 400-480 nm. [1] Blue light is primarily generated by Light-Emitting Diodes (LED) lighting and digital screens, it has now become prevalent in the world around us. [2] LED lighting creates white light by combining blue light with other wavelengths ...
Yes, blue light glasses work to reduce exposure to blue light, but no, they don't work to protect your eye health or accomplish many of the other claims sellers make, says See.
According to CNN, Dr. Gary Heiting, a licensed optometrist and senior editor of All About Vision explained why all human eyes are actually brown, no matter if they look blue or greenish.

Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
The song wasn't a huge hit when it was released in 1978. It only reached number 86 on the US music charts and viewed as one of Queen's lesser songs, it was only performed live once.However, it has ...
The Tyndall effect is light scattering by particles in a colloid such as a very fine suspension (a sol). Also known as Tyndall scattering, it is similar to Rayleigh scattering, in that the intensity of the scattered light is inversely proportional to the fourth power of the wavelength, so blue light is scattered much more strongly than red light.
