Problems solved by technology

This patent also has a major disadvantage: from the claims of the patent, etc., an opaque outer lens is set on the basis of the spectacle frame, and the eyes are covered by turning down, and there is still a lot of light leaking into the periphery of the lens.
Therefore, when using "fog vision therapy" for near-distance visual work, although the problem of light curvature adjustment is solved, the problem of the collection of visual axes is not solved, resulting in the long-term use of "fog vision therapy" to prevent myopia and easily cause major defects of exotropia

Embodiment 1

[0085] Example 1 Production of a direct-adhesive myopia prevention device

[0086] The thin-walled cover is made of light and elastic black silicone material. In order not to oppress the eyeball and not touch the eyelashes, the device is designed with a concave shape in the middle, which can just cover one eye. The space dimension standard of its cover cavity is when cover body covers eyes, and eyeball is not oppressed, and eyelash just can't touch cavity wall as the criterion. The shape of the rim of the device is designed according to the shape of the face around the eyes, and has a certain radian, so that when the device covers the eyes, the rim of the device can be completely and seamlessly matched with the facial skin around the eyes, ensuring that the contact point No light leaks in.

[0087] In order to enhance the health care function of the device, a drug carrier is arranged on the cover edge of the device. The setting method is as follows: first make a circle of gr...

Embodiment 2

[0091] Embodiment 2 The production of a device for preventing myopia fixed by wearing a headband

[0092] The body of the cover wall is made of opaque impact-resistant polyester polymer material. In order not to oppress the eyeball and not touch the eyelashes, the device is designed with a concave shape in the middle, which can just cover one eye. , the space dimension standard of its cover cavity is when cover body covers eyes, and eyeball is not oppressed, and eyelash just can't touch cavity wall as the criterion. The rim of the device is made of soft silicone material, and its shape is designed according to the shape of the face around the eyes, with a certain radian, so that when the device covers the eyes, the rim of the device can be completely and seamlessly with the eyes. The surrounding face skin is fitted to ensure that no light leaks in at the point of contact.

[0093] In order to achieve that the device has air permeability when covering the eyes, an air-tight ai...

Embodiment 3

[0096] Example 3 Production of a device for preventing myopia fixed by the blocking effect of spectacle frames and spectacle lenses

[0097] The thin-walled cover is made of light and elastic black silicone material. In order not to oppress the eyeball and not touch the eyelashes, the device is designed with a concave shape in the middle, which can just cover one eye. The space dimension standard of its cover cavity is when cover body covers eyes, and eyeball is not oppressed, and eyelash just can't touch cavity wall as the criterion. The shape of the rim of the device is designed according to the shape of the face around the eyes, and has a certain radian, so that when the device covers the eyes, the rim of the device can be completely and seamlessly matched with the facial skin around the eyes, ensuring that the contact point No light leaks in.

[0098] In order to achieve that the device has air permeability when covering the eyes, an air-tight air hole is set on the cover...

Abstract

The invention discloses a device for preventing myopia by adopting an eye-changing sight protecting method and a use method thereof when in short-range visual operation, which belong to the technical field of myopia prevention. The device is characterized by being a cover body, wherein the device is made of a light-tight material, and the middle part is sunken and can just cover eyes. The shape of the cover edge of the device is designed according to the shape of the face around the human eyes and has a certain radian, and a carrier capable of carrying a substance with a special curative effect is arranged on the cover edge of the device. The problem of thoroughly insulating the covered and protected eyes from a light source unsolved by a related patent technology of the eye-changing sight protecting method at present is solved by using the device for preventing myopia; meanwhile, the problem of difficultly coordinating the bend light regulation and the visual axis aggregation of both eyes existing in a fogging therapy is also avoided by using the device for preventing myopia.

Description

1. Technical field [0001] The present invention relates to the technical field of preventing myopia, and in particular relates to a method for preventing myopia without affecting near-distance vision operations (such as reading and studying, using a computer, watching TV, etc.) The purpose of the device and its method of use. 2. Background technology [0002] Experimental and clinical studies have shown that acquired myopia caused by unhygienic eye use is mainly divided into two categories: pseudomyopia and true myopia. The formation of pseudomyopia is mainly during continuous near-distance vision work. In order to make the nearby objects clearly appear on the retina, the ciliary muscle continues to contract to change the lens to adjust the focal length. After a long time, if there is no If you get a timely rest, the ciliary muscle will spasm, so that you can't relax to adjust the shape of the lens to change the focal length when looking far, resulting in blurred vision.
