Description

Technical Field

[0001] The invention relates to the field of eye care equipment, and in particular to a pair of intelligent zoom glasses for vision recovery training and a working method thereof. Background Art

[0002] Based on domestic and foreign theories and demonstrations on the causes of myopia, it is generally believed that long-term and excessive use of the eyes at close range is the main cause of myopia. The main characteristics of myopia are that the axis of the eye lens is too long, the ciliary body of the eye cannot recover naturally, the cornea of ​​the eye protrudes when the eyes are used for a long time, the optical focal length of the eye changes, and the retina cannot focus normally, so that the optic nerve cannot receive clear images, resulting in unclear vision. At present, the vast majority of myopia is non-pathological, commonly known as "pseudomyopia", and the main cause of myopia is excessive near vision. Changing bad eye use methods and relieving visual fatigue is an effective way to restore the self-regulation function of the eyeball and improve myopia. In addition, training vision through auxiliary equipment or devices is an effective means of quickly correcting pseudomyopia. In recent years, research has been conducted on equipment or devices used to improve vision, most of which have the problems of being large in size, not being able to be carried around, and being inconvenient to use. In response to this problem, such devices that are easy to carry and use have been studied.

[0044] The working method of the smart zoom glasses (hereinafter referred to as the glasses) of this embodiment includes the following steps:

[0045] ① Start and reset: The user presses the power switch 52 disposed on the temple leg 12, and the control mechanism 5 starts to work. The control mechanism 5 drives the two rear lenses 22 to reset to the set initial position through the driving mechanism 4.

[0046] ② Automatic focusing according to the user's correction degree: the user sends the correction degree of the user's left eye and / or right eye to the control module of the main control board 51 through his smart device APP, and the control module of the main control board 51 converts the received correction degree into the left and right displacement distance of the left rear lens 22-1 and / or the right rear lens 22-2 relative to the corresponding front lens 21, and controls the driving mechanism 4 to drive the left rear lens 22-1 and / or the right rear lens 22-2 from the initial position to the target position according to the converted displacement distance, and completes automatic focusing, that is, the focus of the optical visual path of the user's left eye and / or right eye falls on the retinal papilla respectively, that is, the optical visual path of the left and right eyes is respectively in the positive focus position; the control module of the main control board 51 uses the target position as the central axis of the left and right movement of this training.

[0047] ③ Determine the movement range of the rear lens in this training of the user: The control module of the main control board 51 uses the ±300 degree range of the left-right correction degree of the central axis of this training determined by step ② (±300 degrees corresponds to the positive and negative defocus positions of the user's vision) as the movement range of the left rear lens 22-1 and / or the right rear lens 22-2 in this training.

For example, if the zoom degree x corresponding to each 1mm of the lens 2 is 50 degrees, the left rear lens 22-1 and / or the right rear lens 22-2 moves 6mm left-right based on its central axis.

[0048] ④ Determine the intensity of this training: the user selects one of the five training speeds according to his / her needs, and sends it to the control module of the main control board 51 through the smart device APP. The control module receives and stores the training speed information sent by the user.

[0049] ⑤ Correction training: When the user puts on the glasses, the control mechanism 5 controls the driving mechanism 4 to drive the left rear lens 22-1 and / or the right rear lens 22-2 to perform a uniform displacement movement to the left and right at a determined speed within the determined interval based on the movement interval determined in step ③ and the training intensity determined in step ④ (i.e., the movement speed of the rear lens 22 relative to the front lens 21), thereby achieving continuous effects of different wearing degrees, that is, the focus of the image falls on the front and back intervals of the user's retinal papilla, and positive defocus, positive focus and negative defocus are continuously and repeatedly changed at a uniform speed on the retinal papilla, thereby achieving the purpose of training and improving vision.

[0050] ⑥ Training ends: the user takes off the glasses, presses the power switch 52 and turns off the power, and the training ends.
