physiological 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 the 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 and no more than moderate.
physiological myopia
physiological myopia refers to myopia formed in the growth and development period to adapt to the influence of the external environment, which is generally not hereditary.
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. There is a substantial difference between physiological myopia and pathological myopia in the differential diagnosis of
and
. 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.
,
psychological myopia
and
have three kinds of bad psychology that can lead to vision loss:
and
wear glasses indiscriminately.
and
think that wearing glasses is a sign of knowledge. They think it’s cool to wear glasses. They 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 a kind of escape psychology. Finding reasons to avoid learning tasks from all aspects has become an excuse. Avoiding learning tasks reduces psychological pressure and often looks in the dark, resulting in decreased vision and easy myopia.
