How often do I take my child to check my eyes? This is a problem that has long plagued many parents, even ophthalmologists. Before answering this question, we should first clarify another question: do we want to achieve myopia prevention and control through examination, or do we have glasses through examination?
1. Prevention and control of myopia: it is hoped that before the vision declines, or before the degree of myopia increases, it is timely detected and intervened by relevant examinations. Main purpose: to avoid the appearance of myopia, to avoid rapid increase in the degree of myopia, to avoid constant replacement of glasses.
2. Glasses: refers to myopia has appeared, or the degree of myopia has increased significantly, the original spectacle power has been insufficient, and it is necessary to dispense or re-match the glasses. Main purpose: to "correct" vision, so that the eyes can see clearly on the blackboard, to ensure daily life.
These two things are fundamentally different!
1. If parents only check for glasses or lenses, they can check at any time, without regular inspection.
2, if the parents are to avoid children myopia, or to control the growth of myopia. Then random examination and single examination cannot achieve myopia prevention and control. According to the child's age, daily eye intensity, eye axis growth rate, choose a reasonable cycle for regular inspection, in order to truly achieve monitoring through data tracking and analysis.
If myopia is to be prevented and controlled, how often should it be more scientific to do a check-up?
The answer is actually very simple, at least it should be checked before the child's myopia increases, which can be called prevention and control. During daily optometry examinations or dispensing glasses, the unit of lenses is a step of 25 degrees. This means that myopia prevention and control tests should be detected and intervened at least before the degree of myopia increases by 25 degrees. If the eye axis is increased by 1 mm, it is estimated that it is about equal to the increase in the degree of myopia by 300 degrees. Eye axis growth below 0.008 mm cannot be detected by refraction examination. Therefore, eye axis monitoring is more important for myopia prevention and control.
The eye axis is an important indicator for monitoring your child's vision!
Eye axis growth rate monitoring is very important for the prevention and control of myopia in children and adolescents, through the data provided by big data on the average monthly growth rate of the eye axis of all ages to calculate the rate at which the degree of myopia may increase, it is recommended that children of different ages conduct more scientific prevention and control checks:
1, 3-5 years old age group (kindergarten stage): it is best to carry out an examination every 3 months, more than half a year of examination, myopia prevention and control is difficult to achieve.
2, 6-12 years old age group (primary school stage): it is best to carry out an examination every 1 month, more than 3 months of examination, myopia prevention and control is difficult to achieve.
3. 13-16 years old age group (junior high school stage): It is best to check every 3 months, and it is difficult to achieve myopia prevention and control after more than half a year.
4, 16-18 years old age group (high school stage): it is best to check every 3 to 6 months, more than one year to check the myopia prevention and control is difficult to achieve.
If during regular examination, it is found that the average monthly growth rate of the child's eye axis exceeds the average growth rate of the age group, it indicates that the child's eye intensity is obviously beyond the limit of the eye. High-frequency examinations (once every 15-30 days) are recommended. Monitoring data guide interventions such as daily eye habits, medication, and scientific wearing of glasses. So as to achieve the effect of myopia prevention and control.
According to the data analysis of the eye axis growth rate, we can clearly see that the risk of eye axis growth leading to the growth of myopia is different in different age groups. Regular checks at different frequencies mean that early detection and early intervention can be achieved. Ultimately, the effect of myopia prevention and control was determined. The 6-12-month interval recommended in the "Manual for the Prevention and Control of Myopia" currently promulgated is no longer suitable for the daily eye intensity of Chinese children and adolescents. For most children and parents, in addition to constantly changing glasses, it is basically impossible to achieve myopia prevention or control.
