Experts say that patients with myopia must first distinguish between true myopia and pseudomyopia. For pseudomyopia, the vision can be restored through treatment. But for true myopia, in order to avoid affecting study, life and work, it is necessary to wear glasses to improve vision.
It is generally believed that patients with a degree of less than 300 degrees are mild myopia. They can only wear glasses when looking far away, and take off the glasses when reading or working at close distances. This can reduce or eliminate the need for adjustment and prevent deepening of myopia.
Patients with high myopia can wear two pairs of glasses. One pair of glasses is a pair of glasses that fully corrects vision. It can be used when looking at a distance, and the other can be used when looking at close by 300 degrees to reduce the use of accommodation and prevent Add the depth number.
However, patients with high myopia, if they do not wear glasses, will often see things at close range, which will cause myopia to deepen. Moreover, if you don’t wear glasses for a long time, your vision will degenerate because your vision is not exercised, which may lead to amblyopia and strabismus.
The role of myopia glasses
1. Myopia glasses can correct vision.
In myopia, the distant light cannot be focused on the retina, resulting in unclear vision of distant objects. After wearing a myopic lens, a clear image of the object can be obtained, so that the vision can be corrected.
2. Myopia glasses can reduce visual fatigue.
Myopia without wearing glasses will inevitably cause the eyes to be extremely fatigued, and the result can only be to increase the degree. After wearing glasses normally, visual fatigue will be greatly reduced.
3. Myopia glasses can prevent exotropia.
When the near vision is near, the adjustment effect of the eye is weakened. Once the effect of the external rectus muscle exceeds the internal rectus muscle, it will cause the ocular oblique. Of course, myopia with exotropia can still be corrected with myopia.
4. Myopia glasses can prevent protruding eyes.
Because the eyeballs of adolescents are still developing, accommodative myopia is very easy to develop into axial myopia. Especially in high myopia, the anterior and posterior diameter of the eyeball is significantly extended, and the appearance is manifested as a prominent eyeball. If the myopia is corrected by normal wearing glasses from the beginning, this situation will be reduced.
5. Myopia glasses can prevent amblyopia.
High myopia without timely wearing glasses often results in refractive amblyopia. As long as you wear suitable glasses, your vision will improve gradually after a long period of treatment.
6. Myopia glasses can prevent complications caused by high myopia
Such as retinal detachment, vitreous opacity, cataract, glaucoma, nystagmus, etc.
It can be seen that wearing glasses is almost inevitable if you are nearsighted, and not wearing glasses will only increase the degree. At this time, glasses for myopia are particularly important.
