- Blue light is located in a narrow band near an outer edge of the visible spectrum, with wavelengths close to those of ultraviolet light. Blue light triggers your eyes to react, especially the lens, retina, and cornea. Some research shows a link between eye damage and short-wave blue light with wavelengths between 415 and 455 nanometers.

Apr 24, 2023 · Blue light, like other colors of visible light, is all around you. The sun emits blue light. So do fluorescent and incandescent light bulbs. Human beings are exposed to more blue light than...
Apr 13, 2023 · You’ve heard of blue light, but what is it? Read about its benefits and risks, as well as whether blue-light-blocking glasses and night mode work to reduce your exposure.
Feb 12, 2024 · Blue light is located in a narrow band near an outer edge of the visible spectrum, with wavelengths close to those of ultraviolet light. Blue light triggers your eyes to react,...
- Blue light is everywhere. Sunlight is the main source of blue light, and being outdoors during daylight is where most of us get most of our exposure to it.
- HEV light rays make the sky look blue. The short-wavelength, high-energy light rays on the blue end of the visible light spectrum scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere.
- The eye is not very good at blocking blue light. Anterior structures of the adult human eye (the cornea and lens) are very effective at blocking UV rays from reaching the light-sensitive retina at the back of the eyeball.
- Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina.
Oct 19, 2023 · Blue light is the component of visible light with the shortest wavelength. It influences our Circadian rhythm and excessive exposure to blue light is harmful to our eyes. For most of us, an action-packed and tiring day ends with a typical wind-down routine.

Aug 3, 2022 · First things first: "Blue light is light in the visible portion of the light spectrum with a wavelength between 400 and 450 nanometers," says Norman Shedlo, OD, an optometrist based in North Bethesda, Maryland. It's typically emitted from the sun, electronic devices and fluorescent and LED lights. Video of the Day.
The light that human eyes can see, as it bounces off objects, has wavelengths of between 380 and 700 nanometres. Within this spectrum, running from violet to red, blue light vibrates with almost the lowest wavelength (400 to 450nm) but almost the highest energy.
