Adjustable prism eyesight exerciser

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...

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 de
