When you turn on most digital devices, their screens are full of light so you can easily access the data. However, the visible light from the screen is much more complicated than you think. Based on the wavelength and energy level of each color, the high energy wave length is short and the low energy wave length is long. Darker colors such as purple and blue are closest to the UV wavelength and intensity. Lighter colors such as red and yellow are located at the other end of the spectrum, with longer wavelengths and lower energy levels. The simplest definition of blue light is high intensity in the spectrum, visible light in the short wavelength range, and high energy visible (HEV) light.
Whether you realize it or not, you are always surrounded by blue light. Most computer monitors, cell phone screens and flat screen TVs are extra blue light sources. This is because white LEDs and blue LEDs combine to form solid-state lamps, which have significantly lower power consumption and power consumption than other sources, making them ideal for electronic devices. Although the blue light in our natural environment has always been around our entire life, the excessive blue light generated on the screen needs our attention.
Although our skin absorbs and treats blue light without much problem, our eyes do not have the same level of protection or filtration. Because the wavelength of blue light is short and powerful, it can pass through the cornea to reach the retina, which is the most sensitive part of the eye. If you stare at the computer screen for a long time, you may start to feel eye pain and headache, which may cause dryness, pain, red eyes and blurred vision. If exposed for a long time, blue light can harm your eyes and cause macular degeneration.
Of course, considering our dependence on mobile phones and computers, it is easier said than done. If you watch TV or work on a computer at night, your body may find it difficult to fall asleep. At this time we need a blue-light film to effectively filter out harmful blue light.
The YIPI blue light filter reduces blue light from the screen by blocking short high-frequency waves and allowing long low-frequency waves to pass. It is the easiest and best way to reduce Blu-ray exposure. Anti-blue film has become increasingly popular as recent research reveals potential damage and health issues surrounding blue light. If you have to work late into the night on your PC or mobile phone, the anti-blue film will ensure that your melatonin is secreted normally and protects your retina.
