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. 

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.

    Different coating with different performance, we have Uncoated(UC), hard coating(HC), AR(HMC+EMI), Blue Cut and   Mirror coating and Tintied different color with sunglasses.

   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.

 

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.
