Embodiment 1

[0039] Embodiment one: see figure 1 , 2 , 7.

[0040]The invention discloses a device for preventing and treating myopia by exercising dark vision. After the component is installed, its light intensity attenuates to between 1 / 100000 and 1 / 1000 of the original intensity. The light transmittance of the lens 2 is specially controlled by setting a component that reduces the light transmittance on the lens 2, that is, when using the device under the light conditions of the classroom, the user can only see the outline of the object through the lens 2, but cannot see the object. Can clearly see the color of objects, that is, at this time, the rod cells in the eyes can play a major role, while the cone cells do not play a role, so that the peripheral areas of the retina can be effectively exercised; when learning or entertainment, if you do not need to use photopic vision, Just wear scotopic glasses, by adjusting the brightness of the environment, only the outline of the object can...

Embodiment 2

[0053] Embodiment two: see figure 1 , 3 , 7.

[0054] The similarities between this embodiment and Embodiment 1 will not be described in detail. The difference is that in this embodiment, the member used to reduce the light transmittance is metal nano powder 8 evenly distributed inside the lens 2, preferably iron powder, Nickel powder, etc., the lens 2 fixed with metal nano powder 8 is gray, and the lens can absorb any color spectrum in a balanced manner, so the viewing scene will only become darker, but there will be no obvious chromatic aberration, showing a real and natural feeling, which is also neutral Color system, obviously, the more metal powder is added, the lower the light transmittance of the lens. The measurement standard is also under the classroom light, only the outline of the object can be seen clearly, but the color of the object cannot be seen clearly, which can meet the purpose of training dark vision to prevent eyesight.

Embodiment 3

[0055] Embodiment three: see 1,4,7.

[0056] In this embodiment, the similarities with Embodiment 1 will not be repeated. The difference is that in this embodiment, the light-shielding member is the dyed layer 9 arranged on the inner wall and / or outer wall of the lens 2. In this embodiment, the dyed Layer 9 soaks the polycarbonate lens in a special liquid containing dyeing substances, and the dyeing substances will be slowly absorbed by the plastic to form a dyed layer 9. If the color needs to be darker, just prolong the time that the lens 2 is soaked in the liquid. However, the measurement standard is also under the classroom lights, only the outline of the object can be seen clearly, but the color of the object cannot be seen clearly, which can meet the purpose of exercising scotopic vision to prevent eyesight.

Abstract

The invention relates to the technical field of medical equipment, and especially relates to an apparatus for preventing and treating myopia by exercising scotopic vision and an application method thereof. The apparatus comprises a frame, eyeglasses and glass arms, and shading members used for reducing light transmittance are arranged at the glass arm. The eyeglass having different shading membersprovide special control for the light transmittance, an object contour can be clearly seen while in use for a user, color of the object cannot be clearly seen, and purposes for exercising scotopic vision and preventing myopia can be achieved. When students have a language class and visual sense is not used, the apparatus of the invention is worn for exercising scotopic vision and preventing myopia; under weak light, the usage of the apparatus can offset myopia development, the photochemical damage and non visual effect of eyes can be reduced, the apparatus can directly prevent and treat myopia, and is capable of preventing and treating sexual precocity and obesity by preventing and treating endocrine dyscrasia, and can reach the purposes of health caring and myopia controlling. The apparatus has the advantages of strong operationality and easy popularization.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for preventing and treating myopia by exercising scotopic vision, and discloses a method for using the device. Background technique [0002] Myopia is listed as one of the three major diseases in the world. According to data analysis, there are currently more than 450 million people with myopia in my country, and almost one out of every three people is myopia, and the myopia rate of my country's population will soon reach 50%. Among them, the hardest-hit areas of myopia are adolescents aged 10-18. The incidence of myopia among adolescents in my country has surpassed that of other countries, ranking first in the world. According to the survey, the current rate of poor eyesight among elementary school, junior high school, high school and college students is 45.71%, 74.36%, 83.28% and 86.36% respectively. Like Shanghai, the myopia rate of young people in school ha...
