What is Anti-Blue Light Screen Protector
What is Blue Light?
The simplest blue light definition is a high-intensity, short wavelength range of visible light on the spectrum. Blue light is a high-energy, visible (HEV) light; falling in the same category of visible light as violet.All visible light falls on a color spectrum based on the frequency of a wavelength and energy levels produced by each color.High-energy waves have short lengths and low-energy waves have long lengths. High-energy, short-length waves like ultraviolet rays are invisible to the eye but fall on the same spectrum.

One of the most common side effects of blue light exposure is digital eye strain. If you stare at a phone or a computer screen for too long, you may start to experience pain in your eyes and headaches. Digital eye strain, also known as computer vision syndrome, may lead to dry, sore, red eyes and blurred vision. With enough prolonged exposure, blue light can harm your eyes and lead to macular degeneration - causing damage the same way UV rays would.
However, avoiding permanent damage to your eyesight is fairly easy because it takes a significant amount of prolonged, repetitive exposure.

G-Tel Glass Anti-Blue Light coatings added our screen protectors can prevent a significant amounts of blue light 41-43% (380nm to 480nm) emitted from these devices from reaching your eyes without affecting the visibility of the display.
