Nowadays, there are more and more myopic children. When you walk into a class casually, there are always a few children wearing glasses. On holidays, the myopia clinics of teenagers in major hospitals can be described as "influenced".
When faced with myopia in the face of children, most parents showed anxiety and uneasiness, and some parents were in a state of bad situation:
"There are so many myopic children, it's no big deal."
"Is myopia just wearing glasses, and you can still have surgery when you grow up!"
Have you ever had the same idea? In fact, these are all major misunderstandings in myopia cognition.
First of all, although myopia is common, it cannot be ignored. In the early days, children who want to join the army or apply for related majors such as aviation and navigation will be restricted, which will affect their future development; in the early days, if they are allowed to develop into high myopia, it will cause a series of complications, such as retinal detachment, glaucoma , and even blindness.

Again, myopia cannot be reversed, and surgery can only correct vision. Simply put, surgery is equivalent to wearing a glasses that are more invisible than contact lenses on the eye. It can eliminate the steps to remove them and restore vision, and cannot reverse the changes that have occurred in the eyes, such as some lesions in the fundus.
Moreover, even if you successfully remove your glasses after surgery, if you do not pay attention to using your eyes, it will cause myopia again.
Once myopia enters, what we can do is prevent it as early as possible. Even if the child is already myopia, try to avoid vision increases and reduce the possibility of high myopia. If you want to prevent and control scientifically, you must start with the causes of myopia. Generally speaking, it is mainly affected by the following three aspects.
Genetic
Congenital genetic myopia is one of the causes of myopia in a small number of children. If any parents are highly myopic, it is easy to pass it on to the next generation. However, this kind of congenital condition is relatively rare, and most myopia is caused by acquired.
Habits
Poor Habits with eyes is the biggest culprit of myopia in children. Watching TV and playing games for a long time, reading books and doing homework at close range, rubbing your eyes with your hands without blinking, etc. These behaviors will cause the ciliary body in the eyes to be in a contraction/tight state, and will not be able to relax over time, resulting in myopia.
In daily life, we must strictly control the time of children's eyes and maintain a reasonable distance of sight.
When watching TV, your eyes are more than 3 meters away from the TV screen or 6 times the diagonal length of the TV screen; when using a computer, the monitor is about 60 cm away from the eyes; when using a mobile phone or tablet, your eyes are about one foot (33 cm) away from the screen.

During use, try to blink more consciously and follow the "20-20-20" mantra, that is, after watching the electronic screen for 20 minutes, look up and look 6 meters away in the distance (20 feet) for at least 20 seconds.
In addition, children should pay special attention to their sitting position reading and writing habits after going to school. Follow the principle of "one inch, one punch, one foot":
Hold the pen and your fingers are one inch away from the tip of the pen, your chest is one foot away from the table, and your book is one foot away from the eyes. At the same time, put your head straight, put your shoulders flat, your body straight, lean forward slightly, and put your legs side by side flat, do not cross your legs or cross your legs.

environment
outdoor fully receives sunlight, which is the best environment to prevent myopia.
However, due to the impact of the epidemic and learning, many children spend less than two hours outdoors every day. In this case, the indoor light environment is particularly important. If they are in a dim environment for a long time, it will cause visual fatigue and cause vision loss.

Therefore, when it is cloudy or needs to study at night, in addition to turning on the room lights, you should also turn on the eye protection lights to light. The placement of eye protection lamps is also very particular, and should be placed directly opposite the seat of the bookshelf, which will help the light source to effectively spill the entire learning desktop.
Generally speaking, the standard illuminance index of the eye protection lamp is calculated from 40-50cm away from the light source. Therefore, it is appropriate to keep the lamp head vertically 40-50cm from the desktop and the horizontal distance directly above 1/3 of the front section of the inclined panel.
When purchasing eye protection lamps, in addition to no strobe, no glare, no blue light, and soft light, it is recommended to purchase a T-shaped headlight header above 50cm, which will have a wider range and a more uniform illuminance.

can be well regulated through outdoor activities, cultivating eye and sitting habits, and improving indoor light environment. Parents must make good use of this golden period of myopia prevention and control.
