What is blue light?
Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call "white light" or sunlight.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. (By the way, a nanometer is one billionth of a meter - that's 0.000000001 meter!)
Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm).
Our Blue Cut Lenses' Advantages
Our blue cut lenses can effectively prevent blue light radiation.And the lenses are of good quality and are not easily broken.

About the Coating
_____________________________________________________________________________________________________________________________________________________________
| Hard Coating Anti-scratch Coating | Anti-reflective Coating Hard Multi Coated | Crazil Coating Super Hydrophobic Coating |
| Avoid ruining your lenses quickly protect them from getting scratched easily | Reduce glare by eliminating the reflection from the surface of the lens not to be confused with palarized | Make the surface of the lenses super hydrophobic, smudge resistance, anti static, anti scratch, reflection and oil |
• INDOOR AND OUTDOOR SCENE CUT
Imported monomer makes coating photochromic lens highly sensitive. It is colorless transparent indoor and changes according to UV strength outdoor. The stronger UV color is, the darker lens color is. Light transmittance will increase quickly when coming back indoorside from outdoor activities. Free scene shift provides customers with comfortable experience.
