What is blue light?

Computer Glasses 1.74 Mr-174 Asp Blue Cut UV420 Blue Cut Hmc Shmc Optical Lenses
    Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call "white light" or sunlight.
    Generally, scientists say the visible light spectrum comprises electromagnetic radiation with wavelengths ranging from 380 nanometers (nm) on the blue end of the spectrum to about 700 nm on the red end. (By the way, a nanometer is one billionth of a meter - that's 0.000000001 meter!)

Blue Cut Lenses

Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.
