What is blue light & harmful blue light?
Blue lights are part of the natural visible light emitted by sunlight and electronic screens. Blue light is an important part of visible light. There is no single white light in nature. Blue light is mixed with green and red light to produce white light. Green and red light have less energy and are less irritating to the eyes. Blue light has a short wavelength and high energy, and can directly penetrate the lens to reach the macular area of the eye, causing macular degeneration. Among them, short-wave blue light with a wavelength of 400-450 nanometers is the most harmful to the retina.
 

Advantages of blue light blocking lens:

Anti-blue light lens can effectively reduce the continuous damage of blue light to the eyes. Through the comparative detection of the portable spectrum analyzer, after using the anti-blue light lens, the blue light intensity emitted by the mobile phone screen has been effectively suppressed, reducing the damage of harmful blue light to the eyes.

Anti-blue light lens mainly reflect harmful blue light through the coating on the lens surface, or add anti-blue light factor through the lens base material to absorb harmful blue light, thus realizing the blocking of harmful blue light and protecting eyes.

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.
