Product Description

What is blue light?

   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).
So approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light.

Blue Cut Lenses

Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.

	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.   Special conductive film: The effective conductive treatment of the coating can make its resistance less than 400nm and form a strong current conductive layer, which greatly enhances the electromagnetic radiation effect of the lens, and has a good blocking effect on the computer radiation, alleviating the symptoms of dry eyes when using the computer.
The lenses are suitable for myopic and non-myopic people!

   Anti-Reflective
    - Eliminate reflections, Increase the transmission!
    - Decreases unwanted glare, eliminating ghost image.
    - Makes the lenses appear somewhat invisible.

   Anti-Smudge
    - High contact angle, repel oil and water, make lenses more stain-resistant.
    - Super-cleanable.

   Anti-Static Electricity/Anti-Radiation
    - Help relieving digital eye strain.
    - Stay Clean, repels dust articles.
 

 

• Innovation of technology, blocking glares

       Adopting Mitsui Chemical's NeoContrast technology, the lens contains a blocking glare ingredient to achieve a brighter and high-     definition vision through clear colors with contrast.

      It can reduce the strong sunlight in the day and the glare from roads during night driving. The front object is clearer to be seen by 
   you when driving which secures your safety, so you can enjoy the wonderful scenery.
