Blue light has shorter wavelengths and higher energy than other colors. Some research shows a link between eye damage and short-wave blue light with wavelengths between 415 and 455 nanometers. Most of the light from the LEDs used in smartphones, TVs, and tablets has wavelengths between 400 and 490 nanometers.3 Oct 2020
What is blue light radiation?
Rays on the blue end of the spectrum have shorter wavelengths and more energy. Blue light is the closest to invisible, ultraviolet light on the color spectrum. Ultraviolet light has the shortest wavelength and is known to be dangerous. It can burn your skin in the form of a sunburn and lead to cancer.
Is blue light radiation harmful?
The short answer to this common question is no. The amount of blue light from electronic devices, including smartphones, tablets, LCD TVs, and laptop computers, is not harmful to the retina or any other part of the eye.
Is blue light and radiation the same?
Visible light and blue light 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.
What does blue light mean?
Blue light is exactly that: light with blue wavelengths—which are supposedly beneficial during daylight hours because they boost attention, reaction times, and mood.
Does Phone blue light filter work?
Android Device Most Android devices should have built-in blue light filters that can be enabled or disabled from the Settings screen. However, the feature's availability and utility depends on your specific device and version of Android. You should be able to find the filter under Settings > Display.
Are Bluelight glasses worth it?
Blue light blocking glasses can help reduce eye strain. Blue light can make it difficult to focus on the screen, making your eyes strain to concentrate. Blue light glasses help increase contrast on your screen, making it easier to focus and subsequently reduce eye strain.
Which light is good for eyes?
Natural sunlight is the healthiest choice for your eyes. Being outside can impact light sensitivity, but indoors, natural light is best. Open the blinds and pull back the curtains. Failing that, go with full spectrum bulbs that mimic sunlight.
What does a red light in a bedroom mean?
The red light tells you that you are available. Extinguishing the light is occupied.
What is natural blue light?
Natural blue light versus artificial blue light The shorter, high energy blue wavelengths collide with the air molecules causing blue light to scatter everywhere. This is what makes the sky look blue. In its natural form, your body uses blue light from the sun to regulate your natural sleep and wake cycles.
