Problems solved by technology

[0012] Another shortcoming of the vision rehabilitation machines in the past is that it is necessary to set aside a certain amount of time to train hard every day during rehabilitation in order to achieve some results
However, this kind of hard and boring training cannot last for a long time, months, or years. The rehabilitators often give up halfway in a short period of time, so that this kind of rehab machine is considered ineffective in the end.

Embodiment Construction

[0056] The dynamic lens vision training device and method thereof of the present invention are described in detail in conjunction with various embodiments and accompanying drawings as follows:

[0057] figure 1 It shows that when the eyeball A of an ordinary person looks at a close object B, the two eyes are in a state of concentrating. However, if the prism C is placed in front of the eyeball A, the position of the two eyes will swing out for image resolution (such as figure 2 shown). The present invention is a dynamic lens vision training device and a method thereof designed by using this principle.

[0058] The general convex lens D structure is as follows image 3 Shown, and the present invention combines convex lens D and prism C to form convex prism E; It can grind out the prism C structure person (as in one side of convex lens D when grinding convex lens) Figure 4 shown).

[0059] The present invention uses the relatively thicker bottom (Base) of the prism as a r...

Abstract

The invention belongs to the technical field of medical care, and relates to a dynamic lens vision training device and its method. The device uses electric or manual control to change the position between the prism and the convex lens, so that the user's line of sight can pass through the The prism or the convex lens can see objects so as to achieve the convenience of use, and effectively achieve the feature of preventing the degree of myopia from deepening. The method is to use the prism to make the eyeball swing outward, and the convex lens to relax the eyeball's adjustment of vision. These two mechanisms are used to slow down the progression of myopia and reduce the degree of myopia; this kind of device can be designed as a head-mounted , glasses hanger type, eye mask type, and table type for placing on the desktop.

Description

technical field [0001] The invention belongs to the technical field of medical care, and in particular relates to a dynamic lens vision training device and a method thereof which allow eyeball muscles to move moderately in a natural state, thereby preventing myopia from deepening and reducing the degree of myopia. Background technique [0002] The structure of the eyeball is like a camera. The ciliary muscle inside the ciliary body is responsible for controlling the thickness of the lens, so that it can adjust the vision (Accommodation) so that the image can be seen clearly when looking far and near. There are six outer ocular muscles on the outside of the eyeball to control the direction of eye movement. Each of the six outer eye muscles of the two eyes coordinates with each other to gaze in the same direction and fix the same target. The two eyes will automatically converge (Convergence) when looking at a close distance, and automatically outward (Divergence) when looking...
