Prevention and control of juvenile myopia to avoid these misunderstandings

Abstract: parents have a deeper misunderstanding about wearing glasses. Many parents who see a doctor for the first time believe that “wearing glasses will aggravate the development of myopia and lead to eye deformation”. In fact, on the contrary, myopia without glasses will aggravate the development of myopia.

1. Misunderstanding: Children’s myopia is false. The more glasses they wear, the deeper they will be.

almost all parents of myopia children who first visit will have such doubts: “isn’t my child pseudomyopia?” Even “talk about the color change of glasses” and think that “wearing glasses is over”. This misunderstanding is due to the failure to understand the essence of myopia. The occurrence and development of myopia is due to the excessive extension of the ocular axis and the mismatch with the refractive power of the anterior segment. Therefore, true and false myopia are not distinguished by age. The so-called “pseudomyopia” of

and

is rare in clinic. It refers to the phenomenon of transient myopia caused by excessive regulation. Children and teenagers’ myopia can be diagnosed only by pupil dilation optometry, so they must go to the hospital for professional optometry, rather than simply inserting a piece of optometry in an optical shop.

and

parents have a deeper misunderstanding about wearing glasses. Many first-time parents believe that “wearing glasses will aggravate the development of myopia and lead to eye deformation”. In fact, on the contrary, myopia without glasses will aggravate the development of myopia. Animal and clinical studies have shown that visual blur is an important factor leading to the development of myopia. Therefore, if myopia is not corrected, it will only aggravate visual blur and lead to the development of myopia.

and

clinical studies have also verified that wearing glasses for myopia is helpful to control the development of myopia. In fact, some institutions in the market solicit customers under the guise of “myopia rehabilitation training”. In fact, they only increase the threshold of fuzzy discrimination by repeatedly stimulating the visual center, not really reduce the degree of myopia. Therefore, the so-called “myopia correction” is an illusion.

2. Misunderstanding: children with myopia should wear glasses lightly. The misunderstanding of

and

is based on parents’ deep-rooted belief that wearing deep glasses is not conducive to controlling the development of myopia. There is a conclusion that “myopia should be fully corrected or under corrected”. Clinical randomized controlled studies show that, Foot correction is more helpful to control the development of myopia in children than under correction (e.g. 150 degrees). Why? First, foot correction ensures that myopia can obtain clear vision in the distance and near, so as to avoid the development of myopia induced by blur. Second, foot correction can maintain normal adjustment and aggregation function, so as to maintain normal binocular monocular function.

3. Misunderstanding: progressive multifocal glasses are a good way to control myopia.

and

progressive multifocal glasses are designed to reduce the adjustment force required for close viewing. Therefore, they are mainly used for presbyopia people. The traditional view holds that myopia is caused by too much tension in the regulation of near sight. However, it is now clear that myopia is not too tight, but inaccurate.

and

for most myopia, there is adjustment lag in looking near. Wearing progressive multifocal glasses will only aggravate the adjustment lag, resulting in more inaccurate adjustment. Progressive multifocal glasses have no effect on the control of myopia in most children, but only have a certain control effect on myopia with near implicit skew and lag adjustment. In fact, the vast majority of nearsighted children do not see the implicit oblique, but the implicit oblique. Therefore, wearing progressive multifocal will not only have no effect on myopia control, but also lead to the imbalance of regulating collective function, which is not conducive to binocular monocular function.
