Usually myopia within 300 degrees belongs to mild myopia, 300-600 degrees is moderate myopia, and more than 600 degrees is high myopia. Now there is a consensus in the medical community, and high myopia has been listed as one of the most important reasons for blindness. Therefore, myopia people must consciously control their own number of myopia, pay attention to using eye hygiene, and do not develop into high myopia.

What are the complications of high myopia?

There are four major complications of high myopia: retina, macular lesions, glaucoma and cataracts.

The retina falls off: The normal eyeball shape looks like an apple. As the number of myopia continues to increase, the patient's eyeballs are stretched out and turned into a junior. During high myopia, the retina changes from a dense structure to a gauze mesh structure, which will seep some water, gradually pull down the retina, the nutritional supply is interrupted, and the function of the vision is lost.

Matsyal lesions: Mattolia contains very dense photosensitive cells and is located in the center of the retina. When the retinal becomes thinner during high myopia, the veins cannot provide nutrition to macular regions. The ischemia and hypoxia can produce new blood vessels of the vessel and cause lesions.

Clasting eye: Medicine has not confirmed the pathogenesis of glaucoma, but the vast majority of this disease has a manifestation of high intraocular pressure, bloating, and eye pain. At the same time, the range of vision will become narrower.

Cataract: For high -visual people, the age of white internal barriers will be advanced to forty or fifty years in advance. Cataracts occur in the lens, and the crystal is turbid to block the light to form mist vision.

Special reminder, there are two blind standards: one is to check the vision schedule below 0.05; the other is the field of vision less than 5 degrees. The three diseases of the retina, macular lesions, and cataracts should be found as soon as possible and treated as soon as possible. The loss of glaucoma's vision is irreversible. Treatment can control the field of view as soon as possible.

Prompting symptoms of blind eye disease

Feel the deformation and turbid vision of the objects, the dark shadows are blocked, the shadow becomes more, and the objects of the objects are worsened and the flash feels.

Can ultraviolet rays prevent myopia?

Ultraviolet rays cannot prevent myopia, but more sunlight can prevent myopia. The sunlight will make the human body produce retinal dopamine and other components, which can make the sclera harder, and the retina is not easy to become thinner.

Unhealthy spine is the culprit for myopia?

This statement is inaccurate. Under the normal physiological curvature of the spine slightly, the veins, central nervous nerves, and vertebral artery in the spinal canal are the best. Longing down for a long time, the cervical spine is highly fatigue, which will cause insufficient blood supply to the brain. Visually showing the eyes, blurred vision, swelling of the eyes, and feel dizzy, but it will not cause myopia.
