It is necessary to wear glasses for 400-degree myopia. If you do not wear them, it will cause the following consequences.
1. The power will get deeper and deeper. If you don’t wear bai glasses or those with relatively low power, it will cause the eyeballs to use a lot of adjustment when looking close and far away, which is more likely to cause eye fatigue, and the power will increase.
2. The development of the visual function of the eyes is hindered. For teenagers and children, if myopia is not correct, wear glasses for correction. It will cause the visual function development of the eyes to be hindered, even after adulthood, the correction will not have a particularly good effect. Some children's eyes will gradually develop into strabismus.
3. It may develop into amblyopia without glasses and often squint to see things, which will cause the upper and lower eyelids to press on the eyeball for a long time, and the excessive stretching of the extraocular muscles will lengthen the anterior and posterior diameter of the eyeball. If you don't wear glasses in time, it will cause amblyopia.
