[0002] The essence of the development of myopia is caused by the increase of the eye axis. Inhibiting the increase of the eye axis can prevent the development of myopia. In the prior art, the increase of the eye axis can be suppressed by myopic defocusing of the peripheral retina, which can inhibit the development of myopia to a certain extent. However, the defocus of the peripheral retina will affect the clear visual field, making it inconvenient to see things around clearly, and also lead to hidden dangers to people's movement safety in special circumstances; at the same time, it is easy to produce visual fatigue, thereby affecting the effect of myopia treatment. That is, the prior art has the problem of controlling the increase of the eye axis while bringing about a small clear vision range, easy visual interference and visual fatigue, which is not conducive to the prevention and treatment of hyperopia, myopia, astigmatism, and emmetropia. In addition, the prior art never considers the correction of astigmatism in the defocus area, which will also lead to the growth of the eye axis. Summary of the invention

[0003] The purpose of the present invention is to provide a grid-type defocused eyeglass lens and therapeutic device for inhibiting the growth of the eye axis, mainly to solve the problems existing in the prior art, such as small clear visual field, inconvenience in seeing things around clearly, hidden dangers in action safety, easy to produce visual fatigue and thus affect the effect of myopia treatment.

[0026] Table 1

[0027]

[0028] illustrate:

[0029] 1. The embodiment is an example of 8 diopter eyes. A1 is the diopter of the hyperopia or myopia correction lens; C1 is the astigmatism of the first astigmatism correction lens; C2 is the astigmatism of the second astigmatism correction lens; B1 is the diopter of the defocus lens contained in the defocus area Sx; B2 is the diopter of the positive power lens contained in the defocus area Sx.

[0030] 2. The diopter prescription of conventional eyeglasses is used as the prescription parameter of the eyeglasses of the present invention, and is designed and manufactured in the visual zones So and Si. The parameter value on Sx is determined to a certain degree according to the requirements of the invention.

[0031] 3. The measured degrees in Sx, So and Si are the values ​​measured by a focal meter after the actual lens is made. There is a certain gap between the measured values ​​and the design parameter values, which does not affect the effect. L is the actual measured prism degree, which does not affect the effect.

[0053] 3) Result analysis:

[0054] Statistical conclusion: Among the 175 children in the experimental group, 158 children achieved a breakthrough in completely preventing the increase of diopter using the present invention, accounting for 90% (approximately regarded as inhibiting the growth rate of the eye axis). Among the 175 children in the comparison group, 83 children achieved completely preventing the increase of diopter using the existing technology, accounting for 47.4%.

[0055] Analysis of invalid cases in the experimental group: It is related to heredity and bad behavior habits. Heredity cannot be controlled artificially.
