WDO Product Description

______________________________________________________________________________________________________________________________________________________________
 

   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).
 

Hev Blue Hight protective design:
Based on the principle of bionic absorption technology, blue light can absorb more than 90% of the high-energy blue light which is harmful to human body by reflecting part of the absorption through the lens.
High-definition raw materials:
With improved monomers as the main raw material and other resins as the supplement, the Abbe number of the whole lens has obvious advantages, and the clarity of the lens is greatly enhanced while preventing blue light.

Ultraviolet protection:
Special substrate treatment, adding anti-blue particles, absorbs the high-energy blue light which in the body in 380nm-500nm band, so as to protect the eyes from injury.
Effective prevention of cataract and macular lesions.

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.
