Most of the light from the LEDs used in smartphones, TVs, and tablets has wavelengths between 400 and 490 nanometers. Some research shows a link between eye damage and short-wave blue light with wavelengths between 415 and 455 nanometers. Blue light has shorter wavelengths and higher energy than other colors. Fluorescent and LED (light-emitting diode) light bulbs also give off blue light.Įach color in the visible light spectrum has a different wavelength and energy level. Together, they make the white light you see when the sun - the main source of blue light - is shining. You may know them by the acronym ROY G BIV. It’s one of several colors in the visible light spectrum. Blue light from electronics is linked to problems like blurry vision, eyestrain, dry eye, macular degeneration, and cataracts. It’s safe to say most of us spend a lot of time staring at screens.
