Light prenatal education is best for three minutes at a time, not more than twelve minutes; 5.8~9 pm or 9~ 10 pm is the time when the child's fetal movement is active. It is best to have a light prenatal education or listen to prenatal education music. Strong light source or thermal light source (such as strong light, heat energy, etc.). ) should not be used, because the stimulation of these light sources is too strong, which will make the fetus feel uneasy. If it ruptures too much, it may damage the vision of the fetus.
If you can send a beam of light to the fetus after seven months, the light will stimulate the retina of the fetus. After light stimulates the photoreceptor cells on the retina, the photoreceptor cells will have a photochemical reaction, which will convert light energy into electric energy and produce nerve impulses, which will spread from the optic nerve to the retina. The cerebral cortex leads to complex physiological changes in the cerebral cortex and improves children's visual level. This will have a good effect on their eyesight, coordination, attention and reading in the future. Some experts say that this principle can't stand empirical science. The light beam that penetrates the uterus through the outer layer of the mother's skin is unlikely to contribute to the child's vision. On the other hand, too strong light beam will frighten the fetus, because the fetus is uneasy, which is not conducive to the healthy development and growth of the fetus. It can be seen that light prenatal education is not an artificial product to protect the healthy development of children's vision. Parents must consider that light prenatal education is not an artificial product to protect the healthy development of children's vision. In the case of most people using it, children should be able to use it. ........
