What is the blue light?
Light consists of gradual colors. When combined with red, orange, yellow, green, blue, indigo, and purple, they produce white light, the sun of nature. Each color in the spectrum has a different wavelength and energy. Light at the red end of the spectrum has longer light and less energy. The light at the blue end of the spectrum has shorter light and higher energy. At the far end of the chromatogram, in addition to red light, there is infrared light. This light is most commonly used for warming lights that emit infrared radiation. The other end of the spectrum other than ultraviolet light is ultraviolet light. These high-energy electromagnetic rays are also referred to as UV radiation.
In addition to the sun, the blue light we are exposed to is also found in fluorescent lights, LED lights (including LED TVs), computer monitors, smartphones and tablet screens. As we spend more and more time on smart devices, the body receives blue light that is 10 times more visible from the computer screen. These screen blue light can have various adverse effects on our body and mind, such as eye fatigue, headache and insomnia.
So how do you reduce the harm of blue light to the body?
First, you need to take regular breaks. Use the 20-20-20 rule to take a break every 20 minutes and focus on objects that are 20 feet away for at least 20 seconds. Let your eye muscles relax and avoid eye strain.
Secondly, there is at least one arm length from the screen of the smart device. And fix the screen, don't let him shake at any time, increase the fatigue of the eye muscles. At the same time, the brightness of the room is higher than the brightness of the screen.
