It refers to part of the visible light spectrum what the human eye can see. Blue light has very short, high-energy waves. In fact, they're only slightly longer and less powerful than ultraviolet (UV) waves.

The harmful effects of blue light

The harm to human eyes is mainly manifested in the eye pathological and human rhythm caused by myopia, cataract and macular disease. Children are particularly suffering myopia since their lenses are so clear that they haven’t the ability to block blue light.

Blue light usually put a great strain on people’s eyes for a long time. Long-term visual fatigue may cause people to deepen myopia, diplopia, easy serial reading and other symptoms which finally affect people's learning and work efficiency.

The third is incandescent light.

Incandescent lamps, like sunlight, have the full spectrum. It also contains violet and ultraviolet light, but it is much smaller than sunlight so it ranks third.

The fourth is LED shelf light with 3000k color temperature.
