Physiological myopia and psychological myopia

Abstract: physiological myopia belongs to acquired primary myopia, which is closely related to near coincidence. Long term adaptation makes the ocular axis longer. Fundus is the result of axial lengthening, but it is essentially different from degenerative myopia., Physiological myopia mainly refers to developmental myopia and adult myopia, including simple myopia, school myopia and acquired myopia. Its essence is a kind of refractive phenomenon, not an eye disease, but a biological adaptation of human beings to modern civilization. Pseudomyopia refers to temporary myopia caused by eye adjustment tension or adjustment spasm caused by abnormal visual load and other factors. After atropine mydriasis, myopia disappeared and presented with emmetropia or hyperopia. School myopia is a primary simple myopia, also known as juvenile myopia, which is caused by the excessive visual burden of students due to the school learning environment for a long time. Most of them are low-grade, no more than moderate, and the vision correction is ideal., Physiological myopia refers to myopia formed during growth and development to adapt to the influence of the external environment. It is generally not hereditary., 2. Characteristics of physiological myopia: 1 Puberty appears, develops slowly, and tends to be stable after development stops.,   2. Generally, it goes through the recessive stage, that is, the far vision is still normal, and the static refraction is myopia.,   3. Both eyes are mostly symmetrical, which can be low or moderate, and those > 6.00D are rare.,   4. There were no other obvious abnormalities except the corresponding extension of the ocular axis, leopard shaped and arc-shaped spots on the fundus, and slight vitreous opacity.,

1 physiological myopia

physiological myopia refers to myopia formed during growth and development to adapt to the influence of external environment, which is generally not hereditary.

2 physiological myopia. Its characteristics:

1 Puberty appears, develops slowly, and tends to be stable after development stops.

  2. Generally, it goes through the recessive stage, that is, the far vision is still normal, and the static refraction is myopia.

  3. The eyes are mostly symmetrical, which can be low or moderate, > 6.00D is rare.

  4. There were no other obvious abnormalities except the corresponding extension of the ocular axis, leopard shaped and arc spots on the fundus, and slight vitreous opacity.

  5. Near vision is normal, and far vision correction is ideal.

  6. Other eye functions were normal with few complications.

  7. Genetic factors are not important. Physiological myopia belongs to acquired primary myopia, which is closely related to near coincidence. Long term adaptation makes the eye axis longer. The fundus is the result of axial lengthening, but it is essentially different from degenerative myopia.

physiological myopia is one of the most common types of myopia among our many types of myopia. When correcting myopia, our majority of myopia patients must first find out which type of myopia they belong to, and then apply the right medicine to the case.

3 there is a substantial difference between physiological myopia and pathological myopia. From the law of development to the formation and refractive performance of myopia, from the etiological mechanism to the prognosis, they are independent and unrelated to each other. Although the concepts of

and

are different, they are often confused, and it is difficult to distinguish them clinically. They can usually be divided according to the following conditions:

and

. 1. Changes in eye function.

such as pathological myopia can show poor corrected visual acuity, elevated light threshold, centripetal contraction of visual field, dark adaptability and abnormal ERG.

2. Whether there are complications.

and

3. Whether the eye axis is in progressive elongation, etc. The main difference between

and

depends on diopter and age. If the degree of myopia is less than -6.00d, but there are degeneration and other diseases and the corresponding decline of visual function, it can also be classified as pathological myopia; In adults, if myopia is greater than -4.00d, but there is no obvious organic change and normal visual function, physiology can not be easily excluded. The upper limit of the degree of physiological myopia can be -4.00d. Since there is no difference between the length of vitreous cavity of myopia and emmetropia at -3.00d, it is also bounded by ≤ -2.00d or < -3.00d.

psychological myopia

psychological factors have not received much attention in the prevention and treatment of myopia. In fact, mental stress will cause physical reaction and strengthen visual fatigue. Some adult visual changes are also related to psychology. Psychological myopia is not limited to teenagers, learning pressure, family environment, interpersonal communication and career pursuit, Even worry about your eyesight can affect your eyesight. If you are short-sighted, you should find the reason. If you don’t pay attention to eye hygiene, you should pay more attention to scientific eye use in future life. If you are psychological myopia, you should correct your psychology unfavorable to visual health, protect your eyes and prevent the continuous decline of visual acuity.

1 psychological myopia

there are three kinds of bad psychology that can lead to vision loss:

wear glasses indiscriminately

think wearing glasses is a sign of knowledge, think it’s cool to wear glasses, and want to wear glasses very much, so they often express their bad eyesight in front of their parents, but they wear glasses indiscriminately instead of myopia, In the long run, it has become true myopia.

and

escape pressure

and

have great learning pressure, resulting in an escape psychology. Find reasons to avoid learning tasks from various aspects. If you can’t see clearly, it becomes an excuse to avoid learning tasksReduce psychological pressure, often look at things in the dark, resulting in decreased vision, which is easy to cause myopia.

fear of wearing glasses

psychologically hate eyes and don’t want to wear glasses. They were originally mild myopia. They didn’t wear glasses for correction and didn’t protect their eyes, which could easily lead to a rapid decline in vision. The psychological factors of

and

have not received much attention in the prevention and treatment of myopia. In fact, mental stress will cause physical reaction and strengthen visual fatigue. Some adult visual changes are also related to psychology. Psychological myopia is not limited to teenagers, learning pressure, family environment, interpersonal communication and career pursuit, Even worry about your eyesight can affect your eyesight.

if you are short-sighted, you should find the reason. If you do not pay attention to eye hygiene, you should pay more attention to scientific eye use in future life. If it is psychological myopia, you should correct your psychology unfavorable to visual health, protect your eyes and prevent the continuous decline of visual acuity. According to the statistics of the Ministry of health, the incidence rate of myopia in China is first, the incidence rate is 50%. According to statistics, blindness due to myopia is the third place after cataract and glaucoma.

is the most common cause of blindness in China. Myopia has been listed as one of the three major diseases. Myopia is seriously endangering the healthy growth of teenagers. At the same time, it affects the selection of high-quality talents in China, and narrowing the selection range of special professionals is a severe challenge to achieve China’s health goal in the 21st century.
