--Blue Light Explained--

 Visible everywhere in our life
 Wavelengths of blue light are between 380nm to 495nm in the range of visible lights with strong energy. It's widely discovered in led light sourced products such as pc, cell phone, game machines and TV etc.

 Caused Digital Eye Fatigue
 Short wavelength, high energy blue light scatters more easily than other visible light and makes it not as easily focused. When you're looking at your digital screen that emit significant amounts of blue light, this unfocused visual light reduces contrast and can contribute to digital eye strain.

 Sleep Disruption Blue light is very important in regulating circadian rhythm
 Blue light can penetrate the crystalline to reach the retina, too much exposure to blue light can damage light-sensitive cells in the retina, which can lead to permanent vision loss. Also, the strong energy can deepen facial oxidation and form chloasma
