Teach you how to get out of the misunderstanding of teenagers’ optometry

Abstract: because teenagers under the age of 18 are in the process of eye development, if they are short-sighted, they must have more than one to two medical optometry every year; If hyperopia occurs, it should be done at least once every six months.

with the increasing popularity of computers and TV sets, more and more teenagers have become “small glasses” because of the increasing time of close eye use. So should they wear glasses or not? Do their glasses fit? What glasses should I wear? How to match glasses and so on is the most concerned problem of millions of parents.


looking at the current situation of optometry for teenagers in China, there are indeed non-standard and unscientific problems, so how to get out of these misunderstandings?

1. Fast and simple optometry

optometry matching is a rigorous medical and procedural process. We can’t simply rely on computer optometry or insert a few lenses, and simply check our eyesight for a few minutes to solve the problem. The time required for a set of scientific and standardized medical optometry is at least 20-30 minutes. Choosing medical optometry is the premise of accurate matching. Especially for teenagers, computer optometry is likely to turn “false myopia” into “true myopia” because it is easy to “overcorrect”.

teenagers under the age of 18 must have medical optometry more than once or twice a year if they are short-sighted because they are in the process of eye development; If hyperopia occurs, it should be done at least once every six months.

2. Ophthalmic examination is not required for optometry:

it should be noted that there are many reasons for poor vision, not just simple myopia or astigmatism. Before optometry, systematic ophthalmic examination should be carried out to exclude other eye diseases other than simple ametropia, such as congenital abnormalities, glaucoma, fundus lesions, etc. in addition, there is keratoconus, because the early manifestation of this disease is the rapid increase of myopia and astigmatism. Early detection and early treatment should be carried out to avoid delaying diagnosis and treatment.

3. Mydriasis is not required over the age of 18:

the importance of mydriasis has been gradually recognized. It is well known that teenagers under the age of 18 should have mydriatic optometry. However, mydriatic optometry should also be carried out for regulatory myopia and hyperopia over the age of 18 to relax adjustment and obtain accurate optometry. Several myopia patients around the age of 20 have received different glasses prescriptions in different glasses stores, some even with a difference of 300-500 degrees. After mydriasis, we checked with a comprehensive optometer and found that we don’t need glasses at all.

4. The lower the myopia, the better:

the glasses matching principle of myopia is the lowest degree of the best corrected vision, and the glasses matching principle of hyperopia is the highest degree of the best corrected vision. However, this does not mean that the lower the degree, the better or the higher the degree, and the vision should be 1.0. If the degree is too low, you still see blurred images, which is easier to promote the development of myopia; Too high degree increases the adjustment, which can also cause visual fatigue and lead to the further development of myopia. Of course, the degree should be adjusted according to the existence of hidden skew, the coordination of eye adjustment and set, etc.

5. When matching glasses, we should pursue the same degree of both eyes:

glasses should achieve the same correction effect and visual quality of both eyes, rather than blindly pursuing the same degree of both eyes, otherwise it will interfere with the visual balance and development of both eyes.

6. Vision loss must be myopia:

when teenagers just have vision loss, they must go to a regular eye hospital or optometry clinic for systematic examination and mydriatic optometry to determine whether it is myopia or the nature and degree of ametropia such as astigmatism or hyperopia. At the same time, pseudo myopia should be excluded and do not easily put on the hat of myopia, Wear glasses when you shouldn’t.

7. There is no difference between medical optometry and ordinary optometry: “what is the difference between

medical optometry and ordinary optometry? Medical optometry emphasizes the improvement of binocular visual function. In addition to accurately checking the diopter of each eye, it is necessary to check binocular balance, eye position, adjustment, binocular monocular function Convergence function, etc. wearing corrective glasses can not only have the clearest visual effect, but also achieve the comfort of wearing glasses and play a role in health care and treatment for the eyes.

8. The deeper the glasses are worn, they can’t be removed:

Some people think that the glasses wear deeper and deeper, and once they are worn, they can’t be removed. This idea is wrong. Myopia patients always see things closer than ordinary people to see clearly, and the closer the object is to the eye, the stronger the regulation of ciliary muscle and the collection of extraocular rectus muscle. If myopia patients use collection and regulation for a long time, they will also cause visual fatigue. If this state is not alleviated, the long-term compression of the eyeball by the extraocular rectus muscle will affect children’s eyeball development, resulting in the continuous lengthening of the anterior and posterior diameter of the eyeball and the deepening of myopia. Therefore, wearing appropriate glasses can not only improve vision, but also alleviate excessive aggregation and regulation to reduce contempt fatigue.
