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.
