A summary to the personal consideration about the light’s influence on myopia, procreation and even philosophy & society

This paper summarizes the author's personal thoughts on some important effects of illumination, spectrum and `the Non-visual effects of light' on axial myopia in recent years, as well as the important effects of `Non-visual effects of light' on human reproduction and even philosophy and society. As far as possible, the author provides the conjecture basis, and also proposes the further verification scheme. Efforts are under way to prove the validity of three main conjectures in animal experiments. The most important speculations is that modern humans may be in a state of sexual excitement, if compared with the people 60 years ago. This wrong state has huge influence on Human reproduction, social customs and all other aspects. In addition, from the perspective of optics, based on the analysis of the concept of focal depth, it is concluded that in addition to dividing day and night based on the `Non-visual effects of light', the light should also be divided into near and far. Desktop reading and writing is using a near-range light, and 300Lx at this time may be too strong, which may lead to axial myopia. The author also believes that too much light in modern people may lead to a low-desire society and philosophically expounds the importance of “darkness”. The author has verified that the light with a low emission of 0.2lx can control the phase of laying eggs in chickens. If it is extended to human ovulation, it will be very terrible, because the illumination of the moon on the ground is also 0.2lx. This partially proves that menstruation originated from the monthly changes in moon light, which may be a dose reference for light to affect human reproduction.
