Most parents have made such mistakes after their children are short-sighted

Abstract: preschool children’s vision decreases, and the results of computer optometry show myopia, which may not be true myopia. Children must have mydriatic optometry before their first glasses. Mydriatic optometry can effectively identify true and false myopia.

with the popularization of various electronic products and the aggravation of schoolwork burden, children’s myopia is also showing a trend of younger age. In August every year, at the peak of children’s optometry and glasses matching, it is reported that the children’s ophthalmology clinic in the ophthalmology center of a public hospital is “difficult to find No. 1” this month, and the number of outpatients in the ophthalmology center of the hospital has increased sharply.

and

found that their children’s eyesight decreased. In order to save trouble, some parents often took their children to the glasses store on the street and matched glasses directly after computer optometry. Is there really no problem with such glasses?

when will children’s vision develop normally?

when a child is born, the structure of his eyes seems to be the same as that of an adult, but his eyesight is very poor. He can’t even recognize the first line of his eyesight chart. After birth, vision can develop only when it is stimulated by the surrounding environment.

and

at the age of three, the average visual acuity developed to 0.6. When they entered primary school at the age of six, they had developed to 1.0 as adults. If this development process is hindered and the child’s vision does not reach the due level of that age, it is amblyopia.

and

children need to be checked to identify true and false myopia for the first time. The vision of

and

preschool children decreases. If the computer optometry results show myopia, it may not be true myopia. Children must have mydriatic optometry before the first glasses, which can effectively identify true and false myopia.

if it is pseudomyopia, the child’s vision can be restored to normal through drugs or visual training. True myopia cannot be recovered due to the elongation of the eye axis. It needs to be corrected by detailed examination, wearing glasses or other means. Misunderstanding of

and

: refuse to dilate children’s pupils, which will hurt their eyes.

and

some parents take their children to the hospital to check their eyesight. When they hear the doctor say they want to dilate their pupils, they waver. Some parents believe that children are too young and mydriasis will hurt their eyes. Truth of

and

: children under the age of 18 must dilate their pupils during optometry.

and

mydriasis drugs themselves do not dilate their pupils, but play another role – paralyzing the ciliary muscles. If you want to measure the true refractive state of the eye, you should relax the ciliary muscle. Children with

and

have high eye adjustment ability. If they do not dilate their pupils, they may detect too high myopia,

experts pointed out that “the general principle is that preschool children use atropine for slow mydriatic optometry; students aged 8-18 can have fast mydriatic optometry. After the age of 18, they can have non mydriatic optometry and direct audition after optometry.” After mydriasis, the pupils become dilated and photophobia will occur. These are normal phenomena. Parents don’t need to worry. They just need to avoid strong light irradiation after mydriasis and don’t use their eyes at close range.

and

first select the medical optometry, and then select the lens and frame. After the standardized medical optometry of

and

, the best frame and lens shall be selected according to the degree, age, nose bridge height, face shape and other factors. The optometrist shall make the medical lens according to the actual inspection data given by the optometrist. Children’s eyeballs are in the development stage. If they wear inappropriate glasses for a long time, it will increase the burden of eye regulation.

misunderstanding: take the optometry results of the hospital to the glasses city to get glasses.

“now children are always exposed to electronic products, their eyesight drops too fast, they change glasses too often, the price of the hospital is too expensive, and it will be much cheaper to go to the glasses city.” Parents with this idea usually choose to go to some low-cost glasses cities with the optometry results of the hospital. Truth of

and

: problem glasses will increase the degree of myopia. According to the results of special supervision and random inspection of

and

fitting glasses, nearly 40% of the fitting glasses are unqualified, and the qualified rate of glasses around the campus is only about 60%. Problem glasses will cause eyesight fatigue, strabismus, dizziness, headache and other symptoms, and increase the degree of myopia.

and

experts suggest that optometry should be carried out through formal channels. An accurate optometry result does not mean that there will be a pair of qualified glasses, because the technical content of processing and production is also very high.

to prevent myopia in children. Children should be examined every six months.

for myopia children, it is recommended to go to the hospital for re examination once every three months. For children who have not yet developed myopia, it is recommended to go to the hospital for re examination every six months. Once the child’s vision drops, go to the hospital for examination as soon as possible.

don’t want to wear glasses?

and

corneal shaping lenses have similar appearance to the well-known contact lenses. However, corneal shaping lens is rigid. It can control and delay myopia through shaping the cornea.

and

at present, the mainstream corneal shaping lenses are mainly worn at night, that is, during sleep. After wearing

and

for about 8 to 10 hours, children can maintain their eyesight at 1.0 all day without wearing glasses.

and

experts emphasize that corneal shaping glasses can only delay myopia and shape the cornea by mechanical action. If children don’t wear them for a few days, the shape of the cornea will bounce back and their eyesight will also decline.

and

corneal shaping glasses have a threshold. They must be over 8 years old. The degree of myopia cannot exceed 600 degrees and astigmatism cannot exceed 300 degrees. They are mainly aimed at teenagers and children. Before wearing

and

, you need to go to the ophthalmology department of a regular hospital for eye screening, Exclude contraindications (such as dry eyes, eye diseases including glaucoma, nystagmus, keratitis, eyelid insufficiency, keratoconus and severe amblyopia, sinusitis, severe allergic constitution, systemic diseases, etc.), then try them on for 1-2 hours, and finally decide whether to wear corneal shaping glasses.

After wearing, you must pay attention to hygiene, and you also need to go to the fitting hospital for review regularly.
