Will the blue light at night in lamp and screen destroy East Asians?

Will the blue light at night in lamp and screen destroy East Asians? How to avoid it? Along the axis of light-melatonin-reproduction, this paper summarized a theoretical model related to the influence of modern lighting and display on human reproduction from literature and then finds out six possible proofs for this model from the history of humans' exposures to light at night. Although these proofs may all have some loopholes, the four standards for healthy light ray at night proposed by this paper only imitate the nature, namely they are tenable even without these proofs. This paper also have measured the proportion of blue light in various light sources, and have evaluated their influences on reproduction; meanwhile, this paper also has proposed concrete solutions and even has developed relevant LED lamps; At last, some suggestions and warnings were offered.
