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.
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.
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.
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.
