Many myopic friends think that there is myopia or try not to wear glasses, otherwise myopia will wear deeper and deeper, in fact, this is a misconception. Myopic people in the adjustment of static, parallel light through the cornea, crystal, vitreous refraction focused on the retina before, that is, the position of the retina in the eye after the main focus, parallel light in the eye first formed a focus and then dispersion, when it reaches the retina is no longer a focal image, but a diffuse ring area, thus affecting the clarity of vision. If you do not wear glasses to correct this, the eye will instinctively increase the adjustment in order to obtain a clearer image, and finally exhaustion leads to adjustment delay, myopia further deepened. The retina will not get normal visual stimulation for a long time and its function will gradually degenerate. Scientific fitting of suitable glasses can not prevent myopia from deepening, but can effectively relieve eye fatigue and maintain good corrected vision. We often encounter friends who have myopia but do not wear glasses for a long time. They do not stop the development of myopia because they do not wear glasses, on the contrary, their myopia is often very large, and even some people’s best corrected visual acuity is lower than that of normal glasses wearers even after wearing glasses. Therefore, the development of myopia is the result of a combination of factors and is not directly related to wearing glasses (except when wearing unsuitable glasses). There is no scientific basis for the statement that “the more you wear glasses, the deeper your myopia will get”.
