For every 300 degree increase in myopia, the axis of the eye grows by about 1 mm. Once a child develops myopia, the degree of myopia rises at 100-200 degrees per year, which means that every 3 days it will rise by 1 degree! Therefore, it is important to pay attention to the development of the child's eye axis, to control the rapid growth of the eye axis and avoid the formation of myopia.
Myopia is not prevented 3 days up 1 degree
There are two stages of your child's eyeball growth
Rapidly developing infancy
The anterior and posterior length of newborn eyeballs averages 16 mm, with the fastest growth in the first year of life. 0-3 years old is the key to eye development, but also a period of rapid development. It begins to slow down at the age of 3, and the size of the eyeball will approach that of an adult at the age of 5-6.
Adolescence
There is another slower growth phase of the eyeball during adolescence, which normally lasts about 10 years or more.
Children's eye axis develops
Myopia is an overall refractive state of the eye, and the growth rate of the eye axis is one of the important indicators for evaluating refractive development.
Children are born with farsightedness. From birth to 3 years of age, the length of the eye axis increases by about 5 mm, and the degree of hyperopia decreases significantly. Children increase their eye axis more rapidly in early childhood. As we age, the eye axis begins to grow slowly by adolescence, and thereafter it grows at a rate of about 0.2-0.3 mm per year.
The standard value of the eye axis is 24 mm, which generally stops growing after full development at the age of 20.
Therefore, it is necessary to control the rapid growth of the eye axis to avoid the formation of myopia.
