Some people with myopia prefer not to see clearly than wear glasses because they are afraid that their myopia will get deeper and deeper after wearing glasses. So is the prescription of myopia glasses really getting deeper and deeper the more you wear them? This is a misunderstanding.
Glasses do not deepen or reduce myopia
Wearing glasses only corrects vision, but does not play a role in preventing and controlling the deepening, and the degree of deepening has little to do with wearing glasses or not, only related to the eye environment and eye habits. Glasses are not worn scientifically and accurately, and they deepen faster. So go to the hospital for medical optometry.
Since myopia is due to the fact that parallel light rays are focused in front of the retina, it is not clear to see things in the distance. If you wear a suitable pair of concave lenses in front of the eye, you can move the image in front of the retina backwards and land right on the retina, so that you can see things clearly.
Myopia patients often need to be closer when looking at things, and the greater the myopia, the closer things must be to the eyeball, and the more important the adjustment effect will be. In order for both eyes to see what is in front of them, the eyeball must be turned inward, and the inward rotation of the eyeball is done by contraction of the medial rectus muscle, which is called the convergence action. If you suffer from myopia, but you need to put things very close to the eye without wearing suitable glasses, it will form excessive collection and adjustment, and at the same time, due to the long-term compression of the extraocular muscles on the eyeball, the anterior and posterior diameter of the eye continues to lengthen, resulting in an increase in myopia.
Myopia is the most important factor of vision loss in children and adolescents, and high myopia may cause a series of adverse complications that seriously affect vision, including retinal detachment, macular degeneration, cataract, glaucoma, retinal choroidopathy, vitreous lesions and amblyopia. According to a survey by the Ministry of Health, the number of teenagers blinded by myopia in China has reached 300,000.
