Children’s lower limit of normal vision and age-related
human eye vision development is a process, as the child grows older, vision will gradually improve. According to the latest clinical diagnosis and treatment guidelines for children with amblyopia, the lower limit of normal vision for children is 0.4 for 3 years, 0.5 for 4 years, and 0.6 for 5 years. Whether the vision is normal and whether it is necessary to wear glasses should be determined by a professional ophthalmologist based on the age and eye position of the child.
Example 1: A child is 4 years old and has a computer refraction of -2.00D under non-ciliary muscle paralysis, and his vision is 0.5 (maybe his normal vision is 0.5). After mydriasis, both eyes +1.00D, that is, normal eyes, do not need glasses.
Example 2: A child is 3 years old, with computer optometry -1.00D under non-ciliary muscle palsy, and visual acuity of 0.4 (maybe his normal visual acuity is 0.4), and check optometry +4.00D after pupil dilation. At this time, we need to wear hyperopia I have glasses (the specific degree of glasses needs to be prescribed by a professional doctor according to the child's age and eye position).

Poor vision is not necessarily myopia.
At first sight, young children have abnormal vision. Parents are often anxious to get angry and do not know what to do.
SO, the optometrist tells you that parents should do this:
, please go to a professional ophthalmology institution to check whether you have "diagnosed myopia". Specifically, the refractive status of the eyes can be confirmed through refractive examination and visual function examination, and if necessary, cycloplegia refraction is required.
Poor vision is not necessarily myopia, there are also long-sightedness, astigmatism, amblyopia, and even ocular organic diseases. When problems are found in the physical examination, they should be checked and dealt with in time.
Please go to a professional ophthalmology department to establish a child's refractive development file, and do corneal curvature, eye axis, intraocular pressure, eye position examination, and if necessary, ciliary muscle palsy optometry.

Establishing refractive development files is a good way to protect eyes.
National myopia prevention and control expert, Professor Yang Jiwen, vice president of Liaoning Province of Aier Eye Group, said that kindergarten physical examination is very important to children’s eye health, and it can find "suspected vision" Children with "problems" also remind parents to pay attention to the following three points:
1. Children who have not been screened by the physical examination may also have myopia, or other conditions (such as hyperopia) that require glasses.
2. The kindergarten routine physical examination has a certain false positive rate and false negative rate. The kindergarten physical examination only finds people with "suspected vision problems", and parents need to take their children for further examination and diagnosis.
3. Kindergarten physical examination is to promptly remind parents of children’s vision problems, and refractive development files are long-term tracking of children’s refractive status, so establishing refractive development files is a good way to care for children’s eyes.
