Above 600 degrees is a high degree of myopia, and the eyes will become obvious protruding and a series of lesions may occur. Such as floaters, glaucoma, retinal detachment, etc. Retinal detachment is the most dangerous, with curtain-like obstructions and tiny white dots in front of your eyes.
In severe cases, there is a crack-like flash. Individual people may go blind. In terms of prevention, we should pay attention to two points:
Wear glasses after true myopia. If you don't wear it, you will squint your eyes desperately when you can't see clearly, and your eyeballs will be squeezed and prone to lesions. Minimize the amount of time you spend near your eyes.
The view inside the house is small, and in your spare time, you should spend more time outdoors looking and moving. Only a subset of people with high myopia will develop severe lesions. Even if people have severe lesions, only a small percentage end up blind.
So don't worry too much. Common Sense Pseudomyopia can be recovered by reducing near eye use and often looking far away for a period of time. There is currently no effective means for true myopia.
Those advertisements are commercial propaganda. Only with strict attention to eye protection can further deepening be prevented. - It is wrong to say that you can't take off your glasses and your vision decreases, but the reality is that you don't need to squint when you put on your glasses, and if you take off your glasses, your eyes forget to squint for a while, giving the illusion of vision loss.
And those who really have a real vision loss are caused by not paying attention to eye protection after wearing glasses. -High myopia due to excessive squinting, the first time you wear glasses, there will be visual distortion and distance distortion, as long as you wear glasses for half a month, it is normal. - Common high myopia is different from hereditary high myopia.

Detailed explanation of the symptoms [floaters] is a slight vitreous opacity.

Cataract is severe vitreous opacity. In severe cases, there are white patches in front of the eyes that block vision. Surgable**.
Glaucoma] Intraocular pressure increases due to poor circulation. When the light is sufficient, the edge of the object is blue (cyanine).Retinal detachment] People will feel that there is a curtain-like occlusion and a large number of tiny white spots (similar to Venus in the eye).
It will be harsh to bright colors or scenery. After looking at it, the image will remain in front of you for a period of time. There is a feeling of red cloth obscuring when blinking in bright light.
In severe cases, there is a crack-like flash. Further deepening may lead to blindness. This can be stopped by laser surgery, so don't worry too much.
Severe shaking of the head should be avoided in general.

Myopia requires wearing glasses every day, but it also needs to be determined according to the severity of myopia.
