When you hold a pen, does your thumb touch your middle finger or your index finger? Don’t underestimate this small action, it could be the cause of your myopia. Myopia prevention and control expert, Professor Chu Renyuan, director of the National Health Planning Commission Key Laboratory for Myopia, visited Xiamen Eye Center to conduct a youth myopia prevention and control clinic and public welfare lectures. The site attracted many parents with their children to listen to the lecture. The most critical period for children’s visual development is from 3 to 6 years old. Myopia prevention and control must be done early and at a young age. At the age of 3, children should have a standardized optometric test and a vision health record. In myopia prevention and control, correct pencil grip is the key. The deepening of myopia is also associated with a wrong pencil grip. Wrong pen grip The pen should be held with the thumb and middle finger of the right hand touching each other, not with the thumb and index finger touching each other straight. When sitting correctly, if the thumb and index finger of the pen grip are pinched or crossed, the fingers will block the line of sight and the child will not be able to see the tip of the pen and will be forced to lower his head or tilt his head to the left, thus closing the distance between the eyes and the book, increasing the incidence of myopia and accelerating the deepening of myopia. On the contrary, if you adopt a posture where the thumb and index finger do not touch each other, not only is the writing force more scientific, but also does not block the normal vision of the gaze, thus ensuring that children use their eyes scientifically.

Three don’t: don’t read in too strong or too weak light, don’t walk to do the car to read, don’t lie down to read. Three one: a foot, a fist, an inch. Eyes on the book a foot, chest from the table a fist, an inch from the tip of the pen.
