Super Clean Coat BR

What is blue light (short wavelengths) ?

Among visible light (wavelength range: 380nm to 780nm), the range of short wavelengths (380nm to 500nm) is called “blue light.” Blue light is emitted in great amounts from electronic devices and LED light sources (e.g. personal computers and televisions that use liquid crystal displays, as well as smartphones). This means that we come into contact with blue light on a daily basis. Blue light has the properties of having strong energy and being prone to scatter in the crystalline body. Therefore, this is the cause of the sense of glare and flickering.

It is possible to see clearly with Super-Clean-Coat-BR

The Super Clean Coat BR resuces blue light and gives a comfortable. clear field of vision

Reducing blue light by approximately 11%

Super-Clean-Coat-BR (SCC-BR) reflects and reduces blue light by approximately 11%*1 (the average reduction rate is approximately 30%*2) with Seiko’s unique coating technology.

Improved feeling of a clear appearance

The Super-Clean-Coat-BR reduces glare and flickers while increasing visibility by cutting blue light. Glare caused by the dispersal of indirect light (the state in which it looks like there is a white mist) is also reduced and the clear sense of vision is improved.

Spectral Transmittance Comparison
  • This is a figure that considers the risk of blue light (wavelength range: 380nm to 500nm) reaching the retina which is obtained by subtracting the average value of spectral transmittance weighted by the solar radiation distribution and blue light hazard function from 1.
  • This is a figure that is obtain by subtracting the average value of the spectral transmittance of blue light (wavelength range: 380nm to 500nm) from 1.

Even greater effectiveness by a combining with Function Color

If you use Super-Clean-Coat-BR (SCC-BR) with Function Color that reduces blue light, it is possible to obtain an even greater blue light reducing effect. Not only does this reduce glare, it also improves contrast in a variety of life settings, so it becomes possible to see even more clearly. This is a SEIKO-only combination that we would like to recommend.

Super Clean Coat BR + Function Color


  • The reflected color will be blue.
  • You may sense the reflection of light sources when coming into contact with strong illuminations by the prescription power (curve) and frame design.
  • You may sense yellow or darkness when looking at something.
  • You may sense back reflection when coming into contact with strong light from behind.
  • If placing an order with colors, you may see a difference between the color sample and the actual color due to the addition of the Super-Clean-Coat-BR. (This will become closer to the color with which the Super-Clean-Coat-BR has been superimposed on the sample color.)

Comparison of lens coating performance

  • It is not possible to carry out processing with a combination of ‘Super-Resistant-Coat-BR,’ ‘Super-Resistant-Coat,’ 'Super Durable Coat,' ‘Super-Clean-Coat-BR / Keep-Clear-Coat-BR,’ ‘Super-Clean-Coat / Keep-Clear-Coat,’ Fogless Coat’ and ‘Super Anti Reflection Coating.’
  • ‘Super-Resistant-Coat-BR,’ ‘Super-Resistant-Coat’ comes with a shock-absorption function.
    (The ‘Super Hydrophobic Coat process’ and ‘PR Coat’ will be different.)
