Generally speaking, strong light will certainly cause damage to children's eyesight, must cause the attention of parents! In general, indoor lights should be turned off when children are sleeping! Indoor light at night has a particular impact on children and can cause permanent damage to their vision.
From birth to the first year of life, it is an important period for the development of children's vision, during this period, development of their eyes is not mature, while in the strong light irradiation, will stimulate the eyes, easy to cause visual impairment.
To a certain extent, children need appropriate light stimulation, but excessive lighting may lead to poor vision in the eyes, serious blindness. In my opinion, soft lighting will be beneficial to the children’s visual function.
