Jul 5, 2022 · Blue-light exposure can affect the retina — the layer of cells lining the back wall inside the eye that sense light and send signals to the brain so you can see. Exposing the retina to shorter light wavelengths is the basis of "blue-light hazard" and contributes to phototoxicity or sensitivity to light. In animal studies, prolonged exposure ...

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. Without getting into complicated physics, there...
UV rays have higher energy than visible light rays, which makes them capable of producing changes in the skin that create a suntan. In fact, the bulbs in tanning booths emit a controlled amount of UV radiation specifically for this reason. But too much exposure to UV causes a painful sunburn — and even worse, can lead to skin cancer. These rays als...
Like ultraviolet radiation, visible blue light — the portion of the visible light spectrum with the shortest wavelengths and highest energy — has both benefits and dangers. Here are important things you should know about blue light:
If you are using your phone constantly — especially if you use it primarily for texting, e-mailing and web browsing — a convenient way to reduce your blue light exposure is to use a blue light filter. These filters are available for smartphones, tablets, and computer screens and prevent significant amounts of blue light emitted from these devices f...
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, especially the lens ...
Mar 14, 2023 · Even without UV sunglasses, only about 1 percent of UV light hits the retina. In comparison, most blue light reaches the back of the eye. A specific type of blue light called high-energy visible light (HEV light) is emitted by electronic devices. The amount of rays coming from this kind of light is still lower than the amount emitted by the sun ...
Feb 27, 2019 · High-energy blue light rays scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere. This greater degree of scattering of blue light is what makes a cloudless sky look blue. 3. Our eyes are not very good at filtering blue light.
Nov 14, 2024 · Blue light, a part of the visible light spectrum, is naturally present in sunlight and is emitted by electronic devices such as computers, smartphones, tablets, and LED lighting.There has been significant discussion in the media about the importance of blue light for our circadian rhythm and mood regulation, and that excessive exposure could be linked to various eye problems.

Blue light is a category of visible light with a wavelength roughly between 380 and 500 nanometers (nm). Blue light is perceived as the color blue, though it may also be present in light perceived as another color, particularly white light. Blue light can be divided into two subcategories: high-energy blue-violet light (generally between 380 ...
