Multi-lens vision correction method and its apparatus

Abstract

The present invention discloses a multi-lens vision correction method and its apparatus that use two lenses to form a lens module as a basic structure, and a lens closer to an eye is a concave lens preferably disposed close to the eye as much as possible for correcting the focusing, so that a myopic person can see an object at a far distance. The invention also corrects myopia with excessive minus optical power compensation, and the lens at a distance farther from the eye is a convex lens having opposite characteristics with the lens at a distance closer to the eye according to the excessive compensation, and the invention uses and selects a lens combination with appropriate optical power, so that the final image is produced at a position closer to the front along the central optic axis, and the virtual image of an object converted by the lens module is designed, controlled and converted at a farther distance to change the previous habit of a user. The visual environment of a myopic person is extended from a short distance to a longer distance, and the person's eyes can sense a farther and bigger object, and the Ciliary Body and Lens move to the focus and form a final image at the Retina, unlike the movement made by naked eyes to observe an object. The myopic persons will use their eyesight to view objects at a zone farther than the actual distance. By a natural operation of the physiology of sight and balance of users′ habit, pseudomyopia can be balanced and abnormal elongation of the axial length of an eye due to bad habits can be stopped, and thus achieving a vision correction effect.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a multi-lens vision correction method and its apparatus that adopt a non-surgical method to correct focusing images on a Retina of a person to solve a myopia problem caused by the person's habits. In addition to providing a tool for recovering a person's normal vision, the invention also keeps the Ciliary Body and Lens of the person's eyes operated in a range of sight with a relatively far distance to change an old bad habit of getting used to a narrower visual environment and prevent the myopia problem caused by the bad habit from being deteriorated. If a person has a pseudomyopia problem, then the normal naked eye's vision can be recovered gradually by using the method of the invention. A lens module having two lenses is used as a basic structure, and a concave lens is used at a position closer to an eye and preferably having the smallest feasible distance from the eye to correct t...

Benefits of technology

[0008] Therefore, it is a primary objective of the present invention to provide a multi-lens vision correction and its apparatus that use at least two lenses to form a basic architecture of a lens module, and a lens is closer to an eye, and the distance from the eye is as close as possible, such that the focusing for the vision correction allows a myopic person to see an object at a far distance clearly, and has an excessive compensation of minus optical power for the vision correction.

[0009] The lens at a distance farther from the eye is a convex lens having opposite characteristics with the lens at a distance closer to the eye according to the excessive compensation, and the invention uses and selects a lens combination with an appropriate optical power to produce a final image at a position closer to the front along the central optic axis, and the virtual image of an object converted by the lens module is designed, controlled and converted at a farther distance, so that a short distance is extended to a long distance, and the Ciliary Body and Lens of a person's eyes are moved for focusing and maintaining the final image at the Retina and thus the person can see objects clearly in a desired range. Unlike the movements made by a naked eye to observe the same object, the myopic persons′ habit of using eyes is changed by a non-surgical method. Through the training that takes the regular learning, working and living conditions into consideration, a person's way of focusing an image can be corrected, and thus the present invention can recover the normal vision.

[0010] The secondary objective of the invention is to provide a multi-lens myopia correction apparatus that makes the Ciliary Body and Lens of a person's eye to be operated at a zone equivalent to the situation of seeing an object a farther distance without emphasizing on any particular object. The distance of an object can be extended from a near distance to a farther vision distance depending on the environment of a myopic person, so as to improve the vision of the myopic person and balance the movement of the involuntary muscles of the eyeballs. In other words, usually we cannot change the fact that we need to stay in a narrower environment causing a bad habit that leads to myopia. The invention changes the perceived environment to a larger, longer and wider perceived environment. With the application of the present invention, the perceived space can become larger than the real space. An eye will therefore accommodate differently by Ciliary Muscles in such a larger, longer and wider perceived environment while maintaining clear eyesight. The previous bad habit of a myopic person can be corrected by a new habit of guiding and controlling the person's Ciliary Muscles to relax as much as possible when even looking at an object at a near distance, and such arrangement can solve the problem of deteriorating myopia and can retard or even stop an increase of the axial length which will cause pathological changes to a critical myopic person. For pseudomyopia caused by bad habits of using eyes, the present invention can convert the distance and size of an object to improve of a person's habit of using eyes, and thus the myopia can be eliminated completely after the method and apparatus of the present invention have been applied for some time.
