WHAT IS BLUE LIGHT?
Blue light is the high energy & the strongest portion of the visible light. Due to its short wavelength, its frequency is very high. Size of this portion is usually around 380- 500 nanometers. High frequency translates into high radiation. Human eyes find it difficult to tolerate the blue light. This portion of the light flickers more than weaker portion and this is one of the reasons why we experience a headache, eye fatigue, blurry vision etc when our eyes are exposed in the blue light.
