Is your child pseudomyopia or true myopia? If you don’t pay attention to these, you may turn “false” into “true”!

Abstract: there are organic changes in the eyeball. The anterior and posterior axis of the eyeball becomes longer. After passing through the refractive system, the parallel light can not gather on the retina, and then look at the distant objects blurred. True myopia is irreversible. It is generally difficult to self adjust and recover. It needs to be corrected with glasses or surgery.

whenever children have blurred vision, parents’ first reaction is often: myopia, it’s time to wear glasses! But in fact, myopia does have the difference between true and false. Blind glasses, be careful to make “false” into “true”!

pseudomyopia

most of them are due to ciliary muscle spasm and tension caused by long-time close reading and writing. The adjustment cannot be relaxed when looking at a distance, so they can’t see clearly when looking at a distance and their eyesight temporarily decreases.

true myopia

the eyeball has organic changes, the anterior and posterior axis of the eyeball becomes longer, and the parallel light cannot gather on the retina after passing through the refractive system, so as to see the distant objects blurred. True myopia is irreversible. It is generally difficult to self adjust and recover. It needs to be corrected with glasses or surgery.

and

how to identify true and false myopia

and

children are in the period of growth and development and have strong adjustment ability. The children should be taken to a professional ophthalmic hospital for mydriasis objective optometry, so as to expand the pupil and paralyze the ciliary muscle, so as to measure the real degree.

what are the symptoms of pseudomyopia?

far vision is lower than near vision

far vision is less than 1.0, and near vision is equal to 1.0.

visual acuity is unstable

may get better after a period of rest, and become worse when you look closer. The curative effect of

and

pseudomyopia are effective for all kinds of treatments at present, and can relapse when stopping treatment and restoring close-up effect.

and

are more common in teenagers.

and

because teenagers have strong adjustment ability, pseudomyopia is more common, but a few young people engaged in near work can also occur.

what factors may cause myopia? Genetic factors such as

and

are the genetic factors: the study shows that the incidence rate of myopia in the next generation is high, and the genetic tendency of myopia is recognized, especially high myopia.

and

nutritional factors: due to the lack of some or some important nutrients during the growth and development of the eye, the eye tissue becomes relatively fragile. Under the action of environmental factors, myopia is more likely to occur.

and

environmental factors: the occurrence and development of myopia are closely related to close eye use. At the same time, too strong or too dark lighting, the popularity of electronic products, LED light irradiation, etc. also affect teenagers’ correct eye use habits. Bad eye habits of

and

: teenagers have strong eye adjustment ability and great extension of eye wall. When reading, writing and other close work, they not only need to play the role of eye adjustment, but also need the cohesion of both eyes. In this way, the extraocular muscles exert a certain pressure on the eyes. Over time, the front and rear axes of the eyes become longer, forming myopia.

how do teenagers prevent myopia

maintain a scientific eye posture: when reading and writing, keep your eyes at a distance of more than 33cm from the book and pen, and maintain a correct sitting posture. Never read while lying or walking, or in bad light.

overlooking method: after using your eyes for a period of time, try to look at the distance and look at the green trees better. Twice a day for 15 minutes. To relieve eye fatigue.

and

eat more eye care food: supplement vitamins A and B and trace elements such as calcium, chromium and zinc, eat less candy and high sugar food, and eat more carrots, eggs, spinach, etc.
