The safest and most effective way for adolescents (under 18 years old) is to wear glasses scientifically and reasonably. Myth: The more you wear glasses, the deeper they get, and the more you wear them, the more you can’t take them off. If you are nearsighted and do not wear glasses, you will have two consequences: first, it is easy to cause vision fatigue, which affects learning and work; second, when looking at things, both eyes often squint into a slit. In the long run, the upper and lower eyelids will compress the eyeball causing a shift in astigmatism, and the front and back eye axis will elongate, making myopia increasing. Myopic eyes should wear glasses correctly: 1, myopic glasses can correct vision. Nearsightedness is caused by the fact that light from far away cannot be focused on the retina, resulting in unclear vision of distant objects, while wearing myopic glasses, you can get a clear image, so that vision can be corrected. 2, myopic glasses can reduce visual fatigue. Myopia and do not wear glasses, will lead to glasses easily fatigue, the result can only contribute to the increasing degree of deepening. After normal wearing glasses, visual fatigue phenomenon will be greatly reduced. 3, nearsighted glasses can prevent exotropia. Myopic eye near, the eye regulation role is weakened, a long time the role of the eye outside the straight muscle more than the inner straight muscle, will cause the eye position exotropia. Of course, myopia with exotropia can still be corrected by myopia glasses. 4, myopic glasses can prevent the protrusion of the eye. As the eye is still developing, adolescents are very prone to develop axial myopia. In particular, highly myopic eyes, the front and rear diameter of the eye significantly lengthened, the appearance of the protrusion of the eye, if myopia at the beginning of the normal wearing glasses correction, this situation will be reduced, or even can not occur. 5, myopia glasses can prevent amblyopia. High myopia without timely wearing glasses, often resulting in refractive error amblyopia, as long as the appropriate glasses, after a longer period of treatment, vision will mostly gradually improve. Myopia glasses have a preventive effect on high myopia-induced comorbidities such as retinal detachment, vitreous opacity, cataract, glaucoma, nystagmus, etc. Therefore, myopic patients should choose a regular optician, as long as the glasses are properly fitted, worn from time to time, and pay attention to daily vision hygiene, the myopia can be stabilized or even reduced. Myopia correction for adults (18 years old and above): Wear appropriate glasses and, if necessary, undergo myopic refractive surgery. What is the best way to get the right pair of glasses? There are 5 simple principles: 1, vision loss, first of all, you should ask an eye specialist to check, to exclude other eye diseases; 2, refractive error must be prescription lenses, should first check the shadow (primary examination), no contraindications to the best full dilated pupil examination shadow, in order to get an accurate objective refraction. For the complex refractive state should be medical optometry if necessary; 3, before prescription lenses must also be retested, that is, without dilating the case of trying on glasses. The objective prescription is slightly adjusted to make the subjective feeling comfortable, so that you can choose the best acceptable refraction; 4, rely solely on computerized optometry prescription method is actually undesirable, it is difficult to be accurate for adolescent myopia. The key is: accurate optometry, excluding pure computerized optometry, advocate to the hospital and regular opticians for optometry.
