Abstract: myopia is a kind of ametropia. On the premise of static refraction, distant objects cannot converge in the retina, but form a focus in front of the retina, resulting in visual deformation and blurring of distant objects., In recent years, due to heavy learning load and lack of attention to eye hygiene, more and more primary and secondary school students suffer from myopia, showing a trend of younger age. Some people in their teens have become a group of people wearing glasses, which makes people of insight deeply worried., Possible adverse consequences of myopia: myopia is a kind of ametropia. On the premise of static refraction, distant objects cannot converge in the retina, but form a focus in front of the retina, resulting in visual deformation and blurring of distant objects., I. the anterior posterior diameter of the eyeball of high myopia keeps growing and becomes a long oval. Due to the backward expansion of the sclera, the choroid around the optic nerve nipple shrinks, and a half moon shaped myopia arc spot is formed on the temporal side of the optic nerve nipple, which further develops into a circular arc spot. A series of diseases also occur in the fundus. The retina and choroid diffuse atrophy, and the retina becomes fragile and thin, In particular, retinal degeneration and atrophy in the posterior pole of the eyeball and macular region, macular hemorrhage, the formation of black spots, and serious damage to vision., Second, myopia, long-time close work or reading, will produce visual fatigue, feel heavy eyelids, eye swelling, headache, nausea, dry eyes, etc. For high myopia above 600 degrees, the eye axis is obviously elongated, forming posterior scleral staphyloma, a series of diseases occur, and even cause retinal detachment and blindness., III.

in recent years, due to heavy learning load and failure to pay attention to eye hygiene, more and more primary and secondary school students suffer from myopia, and show a trend of younger age. Some people in their teens have become a group of people wearing glasses, which makes people of insight deeply worried.
myopia may lead to adverse consequences:
myopia is a kind of ametropia. On the premise of static refraction, distant objects cannot converge in the retina, but form a focus in front of the retina, resulting in visual deformation and blurring of distant objects.
1. The anterior posterior diameter of the eyeball of high myopia keeps growing and becomes a long oval. Due to the backward expansion of the sclera, the choroid around the optic nerve nipple shrinks, forming a half moon shaped myopic arc spot on the temporal side of the optic nerve nipple, which further develops into a circular arc spot. A series of diseases also occur in the fundus, and the retina and choroid diffuse atrophy, The retina becomes fragile and thin, especially the degeneration and atrophy of the retina in the posterior pole of the eye and the macular region, macular hemorrhage, black spots are formed, and vision is seriously damaged.
II. Myopia will have visual fatigue, heavy eyelids, eye swelling, headache, nausea, dry eyes and so on. In high myopia above 600 degrees, the eye axis is obviously elongated, forming posterior scleral staphyloma, a series of diseases occur, and even cause retinal detachment and blindness.
III. The anterior posterior diameter of the eyeball of high myopia keeps growing and becomes a long oval. Due to the backward expansion of the sclera, the choroid around the optic nerve nipple shrinks, forming a half moon shaped myopia arc spot on the temporal side of the optic nerve nipple, which further develops into a circular arc spot. A series of diseases also occur in the fundus, and the retina and choroid diffuse atrophy, The retina becomes fragile and thin, especially the degeneration and atrophy of the retina in the posterior pole of the eye and the macular region, macular hemorrhage, black spots are formed, and vision is seriously damaged.
and
IV. cause vitreous opacity and liquefaction, including partial concentration and dot, strip or flocculent turbidity, which float up and down with eye movement, often adhere to the retina, pull the retina and produce a hole, and the liquefied vitreous enters under the retinal membrane through the crack, resulting in retinal detachment. The retina is the place where the visual cells are located. The visual cells are receptors specially stimulated by light. After the onset of retinal detachment, the retina will lose its nutritional supply and become diseased.
