What you must know about high myopia

Abstract: myopia refers to that when the eye is in a static state, after the parallel light passes through the refractive system of the eye, the focus is concentrated in front of the retina and can not be clearly imaged. The degree of myopia increases in direct proportion to the length of the ocular axis. For every 1mm increase in the length of the ocular axis, the degree of myopia will increase by 300 degrees.

myopia degree ≥ -6.00d is high myopia. Many people do not understand or pay no attention to high myopia. In fact, many eye diseases tend to be high myopia. Why? The eye care expert of Shenqiu Guangming ophthalmic hospital answers your questions!

high myopia axis will gradually elongate!

and

myopia refers to that when the eye is adjusted in a static state, after the parallel light twists and turns through the refractive system of the eye, the focus focuses in front of the retina and cannot be clearly imaged. The degree of myopia increases in direct proportion to the length of the ocular axis. For every 1mm increase in the length of the ocular axis, the degree of myopia will increase by 300 degrees. Therefore, with the increase of myopia, the ocular axis will gradually elongate.

high myopia is related to genetic genes! The scope of

and

is extended to three generations of immediate relatives. Both parents or one of them has high myopia, and their children have myopia at a relatively early age, and the degree of myopia is often more than 600 degrees. Of course, there are people with high myopia without family history. Therefore, although high myopia has a genetic tendency, it is not absolutely genetic.

people with high myopia should stay away from strenuous exercise!

due to the extension of the ocular axis, the eyeball is usually prominent, and the posterior pole of the eyeball is expanded, which is prone to degeneration and the possibility of increasing the hole. If the eyeball is injured by strenuous exercise or careless trauma, the retina is more likely to degenerate or even separate.

high myopia is the “fuse” of eye diseases.

compared with people with normal vision, the probability of ocular tissue generator qualitative pathological changes is much greater, such as macular degeneration, glaucoma, cataract, retinal detachment, and even blindness.

and

are far from misunderstandings. The misunderstandings of

and

in bright vision – you don’t need to check your eyesight under the age of 3?

truth answer:

is a big mistake! Especially for eye diseases with family genetic history, only early detection and corrective treatment will not affect the development of normal vision, otherwise it will easily lead to complications such as amblyopia and strabismus.

and

misunderstanding 2: direct glasses without mydriasis?

truth answer:

mydriasis is to make the ciliary muscle temporarily paralyzed and obtain more accurate optometry results. Only in this way can glasses be used to correct vision, otherwise the effect will be counterproductive. Three misunderstandings of

and

only need a pair of glasses from small to large? Truth answer of

and

: the refractive state of

and

eyes will change dynamically with age. At the same time, due to lens wear and other reasons, it will also affect the visual quality and lead to correction deviation. Therefore, regular inspection should be carried out, and glasses should be replaced in time according to the doctor’s advice to correct vision.

and

protect your eyes. Start from everyday life.

and

work and rest combined with

and

use your eyes for a period of time, rest for 10 ~ 20 minutes, you can look into the distance or do eye exercises. Keep good work and rest habits, get enough sleep and don’t stay up late.
