Abstract: myopia can’t see the distant target. If the target is gradually moved closer to the eye and the light is scattered to a certain extent, the focus will move backward. When the target moves closer to a point in front of the eye. The closer this point is to the eye, the deeper the degree of myopia., In this information society, many people suffer from myopia, especially some students and some office workers who face computers every day. Myopia is particularly common, but myopia appears, few people are treated, often wear glasses. In fact, myopia is best treated. Wearing glasses for a long time will increase the degree of your eyes. Then, what are the hazards of myopia that need our vigilance?, What are the hazards of myopia that need our vigilance? Only by understanding the hazards of myopia can people pay enough attention to its treatment. Director Zhu, an ophthalmologist of Beijing Bo’ai Eye Hospital, gave us a brief introduction: what is myopia?, Myopia refers to a refractive state in which the focus falls in front of the retina after the parallel light is bent through the refractive system of the eye without adjustment., Therefore, myopia can not see the distant target. If the target is gradually moved closer to the eye and the light emitted is scattered to a certain extent, the focus will move backward.

what is myopia?
myopia refers to a refractive state in which the focus falls in front of the retina after the parallel light passes through the refractive system of the eye without adjustment.
therefore, myopia cannot see the distant target. If the target is gradually moved closer to the eye and the light emitted is scattered to a certain extent, the focus will move backward. When the target moves closer to a certain point in front of the eye. The closer this point is to the eye, the deeper the degree of myopia.
what are the hazards of myopia?
1. Low vision, dry eyes and fatigue often affect the quality of study, life and work. Wearing glasses for a long time will cause inconvenience to life and work.
2. Medium and high myopia will lead to exophthalmos, eyelid relaxation and affect appearance.
3. Limited access to higher education, military service, civil service examination and job search.
4. After old age, you must wear two pairs of glasses because of presbyopia.
and
5, the incidence rate of cataract and glaucoma in myopia patients is significantly higher than that in normal persons.
6. In the next generation, the heritability of myopia is very large, especially medium and high myopia, with a genetic probability of more than 80%.
7. The main harm is medium and high myopia, especially high myopia, which is easy to cause vitreous opacity, retinal hemorrhage and detachment. According to statistics, blindness caused by myopia is second only to cataract, and glaucoma ranks third.
and
should and must actively prevent and treat myopia to prevent its unlimited development.
myopia seriously endangers the retina. It is necessary to be vigilant against
posterior scleral staphyloma: the incidence is 77. 1%。 The main manifestations were posterior expansion of the posterior pole of the eyeball, degeneration and atrophy of the optic nerve and perimacular retina, and decreased corrected visual acuity. The higher the degree of myopia, the higher the incidence of posterior scleral staphyloma.
subretinal neovascularization: the incidence is 5% – 40%. It is manifested as subretinal neovascularization in the posterior pole, causing bleeding and affecting vision.
and
retinal atrophy, degeneration, hemorrhage and hole: due to factors such as lengthening of ocular axis and posterior scleral staphyloma, patients with high myopia are prone to retinal degeneration and hole, causing hemorrhage and retinal detachment, leading to blindness.
retinal detachment, cataract and glaucoma: due to scleral expansion and retinal degeneration, the chance of retinal detachment in patients with high myopia is 7-8 times higher than that in patients with non high myopia. The chance of high myopia complicated with cataract and glaucoma is also higher than that of normal people. What are the hazards of
and
myopia that need our vigilance? Through the introduction, we can see that myopia can do harm to our eyes and body in many aspects, so we must learn to prevent the occurrence of myopia!
