Since the opening of the school year in September this year, the China Campus Health Action Eye Care Project has successively visited many primary and secondary schools in various districts of Beijing to carry out campus vision screening for students. With the advancement of screening, students and parents have independently inquired about their vision results through the "Notice of Vision Screening in Primary and Secondary Schools".
Some parents believe that since the school organizes regular vision screenings, there is no need to go to a professional ophthalmology department for a detailed review, right?
Is that really the case?This issue will give you a detailed interpretation.
Calibration is not a criterion for judging true vision
There are certain limitations in the vision screening of entering the school, which will be affected by environmental factors and equipment factors, so it is not possible to carry out medical dilated eye refraction, nor can it measure the length of the eye axis, and can only check the basic visual data such as the student's naked eye vision, corrected visual acuity and computer refraction power in the non-ciliary muscle paralysis state, and cannot really fully grasp the child's visual health status.
Therefore, if you want to understand the comprehensive vision health status of your child, you can only achieve it by going to a professional ophthalmic medical institution for a detailed and comprehensive vision examination, and detect problems as early as possible, intervene effectively, and achieve scientific prevention and control of myopia.
A detailed review is important
The professional ophthalmology clinic will conduct a comprehensive examination of the eyes, including the refraction power, measurement of the eye axis, eye position, corneal curvature, accommodation, visual function, binocular balance, etc.
Sometimes vision loss is not only due to myopia, but can also be caused by eye fatigue, strabismus, amblyopia or congenital cataracts.
Therefore, after the initial screening at school, if the child is found to have problems such as refractive abnormalities, it is necessary to go to a professional ophthalmic medical institution in time for a comprehensive eye examination by a professional ophthalmologist to further confirm the child's visual condition.
What tests are needed at different ages
3-6 years: ocular biometry
3-6 years old is a critical period for children's vision development, however, at this stage, children like all electronic products with pictures, and these close-up electronic products will cause children's visual development to be hindered.
Normally, our vision can develop up to 10, but judging from the myopia data released by the National Health Commission every year, at least half of the children will have myopia, amblyopia and other vision problems.
Children aged 3-6 years old have been able to cooperate with routine instrument examinations and identify E-word eye charts, at this time, it is necessary to conduct ocular biometric examinations for children to understand the length of the child's eye axis and various ocular physiological indicators, which are the basis for judging the child's farsightedness reserve. It is recommended to have an eye examination every 3 months to better estimate the rate of myopia progression in children.
7-12 years old: visual function tests
We believe that children should have fully developed vision by the age of 90, but in the era of screen reading, children's eyesight has not yet fully developed, and it has begun to decline, and more and more children at the age of 6, farsightedness reserve will show negative values and begin to become myopia.
School-age children who have abnormal vision or symptoms of visual fatigue may need to have their vision tested. Visual function tests can assess the ability of a child's eyes to work together and analyze the causes of vision abnormalities, many of which can be improved by professional visual function training.
Preschoolers can dilate their pupils if they want to detect true myopia or farsightedness.
13-18 years old: fundus examination
At this age, children have more and more courses, and the homework load is getting heavier and heavier, and if they don't pay attention to healthy eyes, their eyesight will get worse and worse.
For children who have developed moderate or high myopia, in order to rule out the possibility of fundus lesions, fundus examination is required, and once fundus abnormalities are found, it is necessary to be timely**.
Therefore, for developing children and adolescents, a comprehensive set of refractive examination and myopia prevention and control measures are necessary protective measures, and it is difficult to achieve the expected purpose with only the eye chart and ordinary optometry glasses used in school screening.
Public Welfare Review Tips
The China School Health Action Eye Care Project will continue to implement the prevention and control of myopia in primary and secondary schools, and children can rely on the paper version of the screening notice issued by the school (refer to the figure below for the specific content of the notice, you can click to enlarge it.)Make an appointment with any public welfare eye care base for a free public welfare review.
