01Is the brighter the desk lamp, the better? To answer first, no. In the past, we all know that we should not focus on using our eyes in a dimly lit environment, which can easily lead to myopia. Therefore, many parents go to the other extreme when choosing desk lamps, pursuing high-brightness lighting effects. The lights used by children to read and write are too bright, and this situation will also hurt the eyes. Some people may be puzzled, why is the light too bright to hurt the eyes? This is because when the human eye encounters strong light stimulation, the pupil will shrink to reduce the amount of light entering the eye. If the eye is used in an excessively bright light environment for a long time, the pupil will continue to shrink, causing the ciliary muscle to over-regulate. Cause eye fatigue, pain, and even dizziness. Everyone should have encountered a phenomenon in life. When you look directly at the light source, you will feel that there is a bright spot in front of your eyes. Even if you remove the line of sight, the bright spot will move along with it, causing temporary blurred vision. This is the macular area of ​​the retina. A "visual afterimage" produced by strong light stimulation. When we use our eyes under such strong light for a long time, it will cause damage to the retina (especially the macula), resulting in decreased visual sensitivity and permanent decline. In addition, adolescents are in the stage of growth and development. Like other organs in the body, the eyes are not yet fully mature and are easily changed by excessive stimulation by external factors. The eyes are stimulated by strong light for a long time, which will cause changes in the function of the eyeball, which will prevent the eyes from developing normally, resulting in the formation of myopia.
