Blue light lamp on the human body has no harm, to consider the time of blue light exposure and the intensity of blue light exposure and other factors.
1. Irradiation time is short, the intensity of weak: daily life in the use of electronic equipment and other more or less blue light. If the exposure time of blue light is short and the intensity is weak, there is no obvious harm to the human body and there is no need to worry too much.
2. Long exposure time and high intensity:
(1) If long exposure to electronic products and dim environment, the intensity of blue light is strong, the eye muscles are in a state of tension, people are prone to visual fatigue.
(2) If visual fatigue does not pay attention, it will lead to excessive dryness of the eyes.
(3) Prolonged exposure to blue light may also cause damage to the retina, easy myopia, caused by retinal tissue atrophy and degeneration over time, may also induce macular degeneration.
(4) If too much exposure to blue light, cataracts may be induced.
So in general, blue light does not cause any harm to the human body, but to consider the exposure time and exposure intensity.
