When parallel light rays are focused in front of the retina after passing through the refractive system of the eye in a relaxed state of adjustment, it is called myopia. Myopic eyes are also called short-sighted because they can only see near and not far. When this eye is at rest, the parallel light from infinity is refracted by the eye’s refractive system and then assembled into a focal point before the retina, while the retina is knotted into an unclear image, and the distance vision is obviously reduced, but the near vision is still normal. 1. Do children with 200 degrees of myopia need glasses? Children who are confirmed to have true myopia through astigmatism can wear glasses, and children over 8 years old can also wear keratoplasty lenses to effectively prevent myopia from progressing. 2.How can myopia be restored in children? Myopia in children cannot be restored, but the only way to effectively control the development of myopia is through keratomileusis, which is a specially designed rigid corneal contact lens that in most cases only needs to be worn overnight for 7-9 hours each night, and will maintain clear vision throughout the day when the lens is removed. 3.Does high myopia progress to blindness? High myopia patients are prone to retinal diseases, such as retinal detachment, and retinal detachment without timely treatment may cause eventual loss of vision, so high myopia patients should avoid strenuous sports. 4, myopia without glasses will deepen the degree? Myopia and bad eye habits related, such as long time close reading books and computers, myopia progress with or without glasses, if you are myopic, do not wear glasses, often useful eye fatigue situation occurs. 5.Can myopic eyes be restored and how? Myopia is divided into true myopia and pseudomyopia, true myopia is irreversible and pseudomyopia can be recovered. If you find that you have true myopia, you need to go to a local hospital for examination and correction, and you can be fitted with corneal shaping lenses to slow down the growth of myopia. 6. What if one eye is nearsighted and the other is not? If you are under 8 years old, you can wear frame glasses; if you are over 8 years old, you can wear keratomileusis, or you can improve your vision by wearing frame glasses. If you are older than 18 years old, you can also correct myopia through myopia surgery if you are eligible for surgery through examination. 7.How to recover from myopia with glasses with long time eye deformation? Generally speaking, the pathology is not recoverable, because myopia leads to eye deformation, which is due to the change of the near sphere axis length, and the surgery will not change this eye pathology, so the preoperative eye appearance will not change as much as after the surgery, but the excimer surgery will improve the vision, and the posterior scleral reinforcement will prevent further progress of high myopia. 8.What is progressive myopia? Progressive myopia, generally simple myopia to 20 years of age no longer develop, but there are a few myopia always develop, especially in adulthood myopia constantly aggravated, the eye axis continues to lengthen, refractive error increases year by year, even up to 20.00D or more, this kind of myopia is called progressive myopia or malignant myopia, degenerative myopia. Progressive myopia goes beyond refractive error to a certain extent and will eventually lead to a series of pathological changes in the entire eye. For example, early degenerative changes that cause vision loss and mild degenerative changes in the vitreous humor.
