Due to the heavy burden of school work and the increase of close eye use such as playing computers and watching TV, the trend of myopia in adolescents is becoming more and more obvious at a younger age. Although parents have a strong willingness to prevent and control myopia, the prevalence of the following four major misconceptions has accelerated the development of myopia to a certain extent. 1, the child is too young not to wear myopia glasses often squinting to see people and objects of children. Many parents will say: “Don’t let the child so young to wear glasses, wear it will not be removed.” This understanding is extremely wrong and very harmful! Children are in the critical period of visual development, to ensure complete and sound vision, the most important thing is to be able to see both eyes at the same time to see a clear image of the retina (fundus). If myopia is not corrected in time, long-term retinal fuzzy image, on the one hand, will induce further lengthening of the eye axis, so that myopia increases, and even cause weak, strabismus; on the other hand, it will also affect the child’s psychological development, manifested as a decrease in interest in the outside world of new things, narrowing the scope of life, or in some cases, affecting the development of intelligence. The more myopic glasses are changed, the more myopia increases. The main reason for the increase of myopia in adolescence, in addition to genetic factors, is the excessive eye burden and unscientific eye habits. During the period of rapid height development, myopia tends to increase faster. Therefore, on the basis of scientific and reasonable correction, whether myopia increases or not has nothing to do with whether or not to change glasses. Experts suggest that young people should have an optometric examination every 3 to 6 months to regularly monitor changes in visual acuity. If the corrected visual acuity is too low, the eyeglasses should be re-checked and replaced with reasonable diopter correction. 3, myopia glasses can not be too clear myopia is the complete correction of myopia for orthopia, to restore the normal relationship between regulation and collection inherent. If you wear low-correction glasses for a long period of time, your eyes do not need to adjust or use less adjustment when looking at near objects. In order to maintain monovision in both eyes, the visual axes of the two eyes must converge, so the relationship between adjustment and convergence will be disturbed. If the accommodation converges to the accommodation, over-adjustment will be produced, which will cause ciliary spasm, i.e., artificially increasing myopia; on the other hand, the accommodation converges to the accommodation, i.e., it develops towards low accommodation, which will result in the imbalance of extra-ocular muscles. When the imbalance of muscles can not be maintained, the binocular visual function will be destroyed, and the eyes will rely on one eye to look at the object, while the other eye is biased to the outside, which will become the temporary alternating esotropia. The optometrist will give your child a reasonable prescription according to his/her visual function, so parents should not intervene blindly. Blindly believe in all kinds of “treatments” in order not to wear glasses or to reduce the number of lenses. Many parents have been deceived by the emergence of “myopia treatment” devices and therapies (massage, acupuncture, etc.) in the society. From a scientific point of view, these treatments may help relieve eye fatigue and restore vision in cases of pseudomyopia, but they do not help in cases of true myopia. Up to now, the most effective treatment for myopia is still optical correction with proper glasses. Therefore, if your child’s vision declines, parents should take the time to have your child examined by a regular eyeglass dispenser and ask for professional help in formulating an appropriate correction plan. The eye is the only organ that perceives external images, and more than 80% of external information is received, processed and perceived by the visual system. Childhood is the peak period of perceiving external things, during this period, parents should correct the misunderstanding, overcome the fluke, blind faith, so that the child can have a complete and good vision based on the best corrected visual acuity!
