At present, the number of primary and secondary school students suffering from myopia is increasing, which is caused by many factors, mainly divided into two categories: congenital factors (genetic factors) and acquired factors (environmental factors). The environmental factors causing myopia mainly include the following three aspects
1) Nutritional status. Adequate nutrition and reasonable diet are the premise of eye health. Protein, vitamins, calcium and other nutrients are to maintain the normal function of the eye, these nutrients lack, it is easy to induce myopia.
2) The habit of using eyes. Bad habit of using eyes is an important factor causing myopia, such as: reading, reading, writing, reading and writing eyes too close to the book, walking or reading in the dynamic, and long time using eyes.
3) Lighting environment. Healthy lighting environment can effectively prevent the occurrence of myopia, while reading and writing under strong light or dim light is prone to myopia.
Studies have shown that lighting environment is closely related to the visual health of children and adolescents. The lighting environment that does not meet the national standard is an important factor leading to their myopia. Because when they are learning in the classroom, in order to adapt to the classroom environment, their visual organs need to adjust themselves, so that the eye muscles are too tense. If they study in the classroom lighting environment that does not meet the standard for a long time, they will cause visual physiological diseases.
Therefore, improving the classroom lighting environment can prevent myopia. At the same time, the classroom lighting lamps should meet the national standards, and the classroom lighting environment should also protect the eye health!
