Nearsightedness has great knowledge of wearing glasses

Abstract: if true myopia does not wear glasses, it will have two consequences: one is that they can’t see the distant target clearly, and they are used to squinting and frowning, which is easy to cause visual fatigue; Second, when viewing, the eyes narrow into a seam. In the long run, the upper and lower eyelids compress the eyeball, and astigmatism may occur.

true and false myopia do you know how to distinguish?

pseudomyopia is not true myopia, but the tension and spasm of ciliary muscle caused by continuous high-intensity and close eye use, resulting in blurred far vision, which can be recovered through treatment. Physically speaking, infants and adolescents have a very strong ability to regulate their eyes. In addition, adolescents spend a long time using their eyes closely, especially when learning and playing electronic products, which leads to excessive regulation and even spasm, resulting in pseudomyopia.

how to judge true and false myopia?

doctors distinguish between true myopia and false myopia by objective and subjective optometry after paralyzing the ciliary muscle with drugs. Usually, pseudomyopia is myopic before medication and becomes emmetropia or hyperopia after medication examination, while true myopia is myopic before and after medication.

often encounter some parents falling into such a misunderstanding: once they find that their children are short-sighted, they pull their children to go to the glasses store to match glasses. As a result, their children really become short-sighted. Because of pseudomyopia, after wearing myopia glasses, the concave lens turns the distant parallel light into divergent light, resulting in blurring when looking at distant objects, which will stimulate human eye adjustment, and the lens bulge can make the imaging fall on the retina to see the object. In this way, after wearing for a long time, the eyes regulate long-term tension and spasm, resulting in functional changes in tissues and organs without organic changes, and finally evolved into true myopia with qualitative changes in ocular axis or refractive components. Can

and

true and false myopia be corrected?

and

for the correction of pseudomyopia, doctors usually treat it through drugs or traditional Chinese medicine, while true myopia cannot be treated. Therefore, it is suggested that parents should pay attention to eye hygiene, keep children away from the environment harmful to eye health, carry out more outdoor activities, and regularly go to the hospital for eye examination, so as to prevent myopia.

do you have to wear glasses for myopia? Do you wear glasses deeper and deeper?

and

studies show that the development of myopia is not directly related to wearing glasses.

and

true myopia will have two consequences if they do not wear glasses: first, they can’t see the distant target clearly, and they habitually squint and frown at the object, which is easy to cause visual fatigue; Second, when viewing, the eyes narrow into a seam. In the long run, the upper and lower eyelids compress the eyeball, and astigmatism may occur. Experts pointed out that visual fatigue, blurred image stimulation and ocular muscle compression on the eyeball may accelerate the growth of ocular axis and deepen the degree of myopia. Therefore, wearing a pair of appropriate glasses can not only solve visual fatigue, but also prevent the degree from increasing too fast.

some people with high myopia (more than 600 degrees) insist on wearing glasses, but the degree will gradually deepen, accompanied by fundus changes, which is called pathological myopia in medicine. The deepening of myopia is related to the type of myopia and family inheritance, and has no direct relationship with wearing glasses. What should I pay attention to after

?

experts remind us to pay attention to eye hygiene after matching glasses to avoid excessive eye use; Don’t be afraid that wearing glasses will lead to the deepening of the degree and avoid wearing glasses or sometimes not after wearing glasses. These behaviors will make Yanqing often in an unstable adjustment state, increase the burden on the eyes, lead to the excessive adjustment of ciliary muscles, and finally lead to the decline of vision and the deepening of myopia.

in addition, experts suggest that patients with myopia should go to the hospital regularly for examination, medical optometry under the guidance of doctors, and then scientific glasses. Never wear inappropriate glasses, borrow others’ glasses or buy a pair of glasses that you think are suitable in the store; The wearing time of glasses should not be too long. Re optometry should be carried out in time, and then replace glasses.
