What is pseudomyopia and what is pseudomyopia

Myopia is generally divided into pseudomyopia, true myopia and mixed myopia. Pseudomyopia is caused by the continuous contraction and spasm of the ciliary muscle, the thickness of the lens increases, and the vision is blurred. Pseudomyopia is a form of functional myopia that can be used to relax muscles, relieve fatigue and restore vision to normal with the use of medications, acupuncture, ear acupuncture and physiotherapy equipment, or through the patient's own strengthening of the eye muscles.

If pseudomyopia is not relieved in time, the eyeball will be compressed by the tense extraocular muscles for a long time, which will eventually lead to the enlargement of the eye axis and become true myopia.

School-age children or adolescents have long-term inappropriate reading, writing or insufficient lighting and other factors, so that the ciliary muscle is often in a state of contraction, and the convex lens is not easy to relax, at this time, the distant parallel light enters the eye, after the convex lens is strongly reflexed, its focus will no longer fall on the retina, but fall in front of the retina, and the vision is blurred, which is called pseudomyopia in medicine.

In summary, the use of the eyes is unhygienic and excessive, which leads to tension and spasm of the ciliary muscles, which causes the light to focus in front of the retina, resulting in refractive error and loss of distance vision. However, this decline can be recovered after rest or **, that is, this myopia eye is reversible, so it is called pseudomyopia, also known as accommodative myopia. Pseudomyopia is characterized by lower distance visual acuity than near visual acuity; After rest or dilated refraction, the refractive power may disappear or decrease; When myopia can be corrected, stopped, and near eye work resumed, vision will decline again.

Dilated refraction can distinguish between true myopia and pseudomyopia.

Because the anterior and posterior diameter of the eyeball has not been lengthened, the structure of the eyeball has not changed, but only the physiological function has changed, so it is generally not necessary to wear glasses. With promptly** and attention to protection, the ciliary muscles are relaxed and vision can return to normal. If it is not paid attention to in the pseudomyopia stage and continues to develop, the anterior and posterior axis of the eyeball becomes longer, and the structure of the eyeball changes, which becomes true myopia.

Pseudomyopia can appear in people who are originally emmetropic and farsighted, or even myopia, so they often mistake the emmetropic eye or even the farsighted eye for myopia, and make the original myopia show a higher degree of myopia.

Pseudomyopia is relieved or eliminated by resting or applying cycloplegic agents, such as 1 atropine eye drops or ointment, or foggy vision** to relax or paralyze the ciliary muscles. If not properly treated, long-term use of near vision can cause the anterior and posterior axial axis of the eye to lengthen, resulting in true axial myopia. Therefore, in the stage of pseudomyopia, preventive measures should be strengthened, strict attention should be paid to eye hygiene, appropriately reduce reading and close work to eliminate more accommodation, if not relieved, the application of cycloplegic agent or foggy vision method to relieve its regulatory spasm, stop reading for a short time, and can be used for eye massage, distant view, outdoor activities, etc., do not rush to wear myopia glasses without dilating the pupil refraction, so as to force more adjustment, the formation of a very deep degree of myopia.

In conclusion, pseudomyopia is characterized by lower distance visual acuity than near visual acuity; After rest or dilated refraction, the refractive power may disappear or decrease; When myopia can be corrected, stopped, and near eye work resumed, vision will decline again. Dilated refraction can distinguish between true and false myopia.

The so-called pseudomyopia is caused by the frequent incorrect use of the eye, the ciliary muscle continues to contract and spasm, and the lens is in a state of thickening. In this way, the parallel light from the outside enters the eye, and after the atrial refraction of the thickened lens, the focus falls in front of the retina, and it is naturally not clear to see things in the distance. During this period, there are no organic changes in the eyeball, and if you can take proper rest and **, pay attention to eye hygiene, and use the eyes reasonably, there is hope to restore normal vision.

However, if it is not corrected in time in the stage of pseudomyopia, it will develop into true myopia over time. **There are many methods of pseudomyopia, mainly relaxation and regulation, such as: the use of cycloplegic agents to dilate pupils, acupuncture, physiotherapy, improve the learning environment, pay attention to eye hygiene, and do eye exercises seriously.

Due to eye fatigue due to looking at the near place for too long, the ciliary muscle is in a state of tension, and the elasticity of the ciliary muscle is reduced or lost over time, and the function of traction of the lens is lost, and the lens thickens and becomes convex and cannot be recovered, resulting in temporary blurred vision, but it can be improved or restored, also known as pseudomyopia. Generally speaking, when adolescents look at near objects, due to the degree of use of accommodation is too strong and lasts for too long, when they switch to distant vision after a long period of reading and writing, they cannot quickly relax the accommodation, that is, the adjustment reaction time is longer than that of the normal person, so the distance vision is relatively reduced.

Hello, pseudomyopia is caused by excessive use of the eye, which causes the ciliary muscles to contract and spasm, the lens thickness increases, and the vision is blurred. Pseudomyopia is a functional myopia, pay attention to scientific eye use in the future, maintain good eye habits, and do not need to wear glasses.

Distance visual acuity is lower in the presence of accommodation, and near vision is normal, and visual acuity can be improved by wearing concave spherical lenses, but refraction is orthotropic or hyperopic in the presence of accommodative paralysis.

It is caused by prolonged use of the eyes at close range, which causes adjustment tension or adjustment spasm, and the inability to relax and adjust when seeing far away, and the vision decreases.

It's usually eye fatigue, and it's not good to overuse your eyes for a long time, so eat more black sesame carrots. Look at something else at a two-hour interval and don't keep staring at the computer.

Pseudomyopia is relative to true myopia. The true myopic eye is when the refractive system of the emmematic eye is at rest.

That is, after the accommodation is removed, the far point of the eye is located within a limited distance. In other words, myopia is caused by congenital or acquired factors that cause the anterior and posterior diameter of the eye to become longer, and parallel rays of light enter the eye and form a focal point in front of the retina, causing blurred vision. On the surface, pseudomyopia is also a blurred vision of the distance, and the near vision is clear, but there is no corresponding refractive change during the dilated refraction examination.

During this period, because the eyeball has not become longer, if you can rest and ** properly, pay attention to eye hygiene, and use the eyes reasonably, there is still hope to restore normal vision, so it is called pseudomyopia. If it is not corrected in time in the stage of pseudomyopia, it will develop into true myopia over time.

Factors such as long-term inappropriate reading, writing, watching TV, playing games or improper lighting in adolescents make the ciliary muscle often in a state of contraction, and the convex lens is not easy to relax. This type of myopia is reversible, so it is called pseudomyopia. In terms of diet, animal liver, eggs, carrots, etc. can be eaten.

Increase physical activity. Correcting sitting posture and adjusting the reading distance are all necessary. Finally, you can drink some Zheng 9 flavor pupil tea, which can improve myopia and relieve eye fatigue.

Long-term improper reading, writing, watching TV, playing games or improper lighting and other factors, so that the ciliary muscle is often in a state of contraction, the convex lens is not easy to relax, at this time, the distant parallel light enters the eye, after the convex lens strong refraction, its focus will no longer fall on the retina, but in front of the retina, the vision is blurred, medically called pseudomyopia. In terms of diet, animal liver, eggs, carrots, etc. can be eaten. Increase physical activity.

Correcting sitting posture and adjusting the reading distance are all necessary. Finally, you can drink some 9-flavor pupil tea, which can improve myopia and relieve eye fatigue.

Generally refers to temporary myopia, which can gradually recover if properly protected.

It's not really myopia, my sister is fake, and it's OK to wear glasses when you want to use them often
