Sight training instrument

Abstract

A visual training instrument comprises a body with a capacity space; a visual target shuttle mechanism installed inside the capacity space which can ensure the visual target to horizontally reciprocate or keep fixed point inside the capacity space; a control component connected with the visual target shuttle mechanism by an electrical method used for controlling the displacement distance of the visual target shuttle mechanism to the visual target; a first and a second flexing part, wherein, the first flexing part is formed outside the capacity space, the second flexing part is formed outside the first flexing part, the first flexing part sticks out to a predicted length from the capacity space and then meshes with one end of the second flexing part when sticks out to a predicted length, and the second flexing part can also stick out to a predicted length from the capacity space and jointly drive the first flexing part; and a observation part, which is located at the extension end of the first flexing part by a slip style, and used for watching the view target inside the capacity space.

Description

technical field [0001] The invention relates to a device for training eyesight, especially a device that can freely expand and contract the length and reduce the overall volume of the device, thereby taking into account the selection and setting of multiple movement modes, the control and maintenance of the automatic movement of the visual target while miniaturizing the device. A vision training device with superior functions, reduced manufacturing costs, good use convenience and enhanced industrial utilization value. Background technique [0002] As the saying goes: the eyes are the windows of the soul. This statement tells the truth that although human beings can live without sight, they will not be able to keep their soul because of the loss of sight. This shows the importance of sight. Therefore, technologies related to improving eyesight have also received considerable attention. Generally speaking, vision improvement technology can use optical instruments or instituti...
