Children are the center of a family, and children's eyes also generally get the attention of parents. Myopia is rapidly becoming a "global epidemic", and the incidence of myopia in children with and is increasing year by year. Faced with the situation of children's myopia, many parents will have many questions and even be at a loss. So, what should we know as parents?
Use of electronic products
It is not wrong to say that electronic products are the number one killer that threatens children's vision ! Nowadays, mobile phones, computers, and ipads are the tools that we use the most frequently with our eyes at close range, and they are also the source of the greatest fatigue for our eyes. Many parents regard tablet computers and mobile phones as "electronic babysitters" because they are busy with work. Children hold these things and play with them all day, unknowingly , resulting in dry eyes and false myopia , until Evolved into true myopia . Experiments show that: playing with mobile phones for 20 minutes, the average vision of children is close to light holiday myopia.
Reading and writing
Experts point out that using the eyes at close range for a long time is the root cause of myopia. Reading and writing are all done by close-range fine visual , mainly relying on visual cone cells . Excessive fatigue of and of visual cells will bring fatigue of the entire visual system. Corresponding pathological and physiological changes will occur in eye muscles and eyeballs.
Watching TV
The TV itself has a certain flashing illuminant , plus the distance is relatively short, watching TV for a long time is more prone to fatigue, especially for children, whose eyesight is not yet mature, it is easy to cause visual damage.

Nowadays, children are the treasures of their parents, giving them what they want, what they want to eat, what to cook (or buy), picky eaters , and unbalanced nutrition is inevitable. The process of vision requires the participation of vitamin A, and the conduction of optic nerve needs the help of vitamin B family . In the absence of vitamin A, the eyes often feel dry, astringent, and easily fatigued. In severe cases, the surface of the whites of the eyes is dry, shrinking, and even lead to corneal ulcers.
psychological factors
This is a factor that is easily overlooked. Excessive tension and depression have certain effects on vision. Afraid to wear glasses, should not wear them; desire to wear glasses, should not wear them indiscriminately and so on.
