【About Blue Light】 Blue light is the blue-colored light which can also be found in natural light. In recent years, as the use of LED has become more popular, "eye fatigue" has become a significant issue. As modern LED contains a large quantity of visible rays of light with short wavelengths compared to the old-cathode ray tubes (between approximately 380 nanometers to 495 nanometers), it has been identified as a major cause of eye fatigue. This product is a protective film designed to significantly reduce blue light. 【Accessory】 Cleaning cloth (nonwoven fabric)
