Problems solved by technology

Although the method and device of this case can effectively achieve the purpose of eyeball training, there is still room for further improvement. For example, the prism or convex prism used in the above-mentioned application has a fixed degree, so for the eyeball, when When the prism or convex prism moves in and out repeatedly, the eyeball must quickly tense and relax the muscles to cope with the change of the lens power, so it is easy to increase the burden on the eyeball

Embodiment Construction

[0058]Hereinafter, the present invention will be explained in detail through multiple preferred embodiments of the present invention in conjunction with the accompanying drawings. First please refer to FIG. 1 and FIG. 2 , which show the design principle of the adjustable prism vision training device of the present invention. What is shown in Fig. 1 is a schematic view of the sight line of the eyeball A of an ordinary person when watching a nearby object B. At this time, the eyeball A is in an inset state so as to focus the sight line on the same object B. According to the present invention, in order to correct the long-term excessive inset of the eyeball and cause excessive adjustment of vision, a lens or optical component with the effect of refracting light can be arranged in front of the eyeball A, such as a prism C or as described in the aforementioned application No. 91116074 The above-mentioned convex prism, the prism C is set in such a way that the light rays incident on...

Abstract

An adjustable prism device for training vision has a fixing part with a window and arranged in the front of the eyeballs of a user, an adjustable optical refraction unit arranged in said window and having the first and the second lenses, and a driver unit for driving the second lens to rotate relatively to the first lens in order to change the included angle between two lenses and in turn the refraction state, which can induce the eyeballs to be projected for training their vision.

Description

technical field [0001] The invention relates to a dynamic vision training device implemented by a prism, in particular to a device that can allow eyeballs to move moderately in a natural state, thereby preventing the degree of 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 eyes will automatically converge (Convergence) when looking at a close distance, and automatically outward (Divergence) when looking at a distance, toward the same targ...
