Abstract: in the ophthalmic clinic, it can often be seen that parents ask to reduce the degree of myopia and glasses because their children have a large degree of myopia. Parents feel psychologically that if the degree of glasses is low, the degree of myopia of children is low. In fact, this is a completely wrong understanding., As we all know, China is a big country with myopia. Moreover, the incidence rate of myopia has been increasing and showing a trend of younger age in recent years. Myopia not only affects far vision, but also causes degenerative lesions of vitreous and fundus. Complications related to high myopia are important factors leading to visual impairment and blindness. Therefore, it is very important to control the incidence of myopia and slow down the progress of myopia., At present, what are the effective measures to control the development of myopia?, I. eliminate ambiguity. In the ophthalmic clinic, it can often be seen that parents ask to reduce the degree of myopia and match glasses because their children have a large degree of myopia. Parents feel psychologically that if the degree of glasses is low, the degree of myopia of children is low. In fact, this is a completely wrong understanding., Uncorrected or undercorrected myopia and astigmatism will cause blurred imaging, which can accelerate the progress of myopia.

incidence rate of myopia has been increasing and showing a younger trend in recent years. Myopia not only affects far vision, but also causes degenerative lesions of vitreous and fundus. Complications related to high myopia are important factors leading to visual impairment and blindness. Therefore, it is very important to control the incidence of myopia and slow down the progress of myopia.
at present, what are the effective measures to control the development of myopia?
I. eliminate ambiguity
in ophthalmic clinics, it can often be seen that parents ask to reduce the degree of myopia and glasses because their children have a large degree of myopia. Parents feel psychologically that if the degree of glasses is low, the degree of myopia of children is low. In fact, this is a completely wrong understanding. Uncorrected or undercorrected myopia and astigmatism of
and
will cause imaging blur and accelerate the progress of myopia. Therefore, when matching glasses, we should follow the doctor’s advice, and parents must not make their own decisions.
II. Outdoor activities
appropriate outdoor sports, activities and play reduce children’s opportunities to use their eyes at close range and increase the time to see far, which is very conducive to the prevention and control of the occurrence and development of myopia.
III. peripheral defocus frame glasses
can correct central ametropia and increase the curvature of image plane field of view, so as to correct peripheral hyperopia or create peripheral myopic defocus lenses to delay the change of juvenile vision. Clear vision and myopic optical defocus are important factors to reduce axial growth and control the development of myopia.
IV. corneal shaping lens
is called OK lens for short. It is a rigid breathable contact lens with inverse geometric design, with flat center and steep side center. OK lens makes the central cornea flat and the paracentral cornea steep through its special collective design, so as to significantly improve the peripheral hyperopia defocus and control the progress of myopia.
