Abstract

A method for preventing and curing myopia of juveniles, caused by reading and writing for a long time, features use of a pair of invented glasses, which is based on bio-optical principle to regulate the distance of distinct vision from near point (250-450 mm) to far point (10m-unlimited), so making eye muscle in relax state on reading and writing.

Description

The method of control juvenile shortsightedness

The present invention is that a kind of effective control teenager is owing to long-time read-write forms bathomorphic method, according to the special eyeglasses of this method invention.

The present invention prevents and treats bathomorphic method and is based on the physiological optics principle, makes teenager's distance of distinct vision that eyes are regulated when read-write move on to far point (10 meters to infinity) by near point (250 millimeters to 450 millimeters).Thereby eyes muscle loosens when making read-write, has eliminated owing to long-term read-write forms bathomorphic pathogeny.Under instructing, the professional can effectively treat because of the nervous low myopia that takes place of eye muscle meat.

Characteristics of the present invention are that the special eyeglasses of wearing long reach goes reading, even write operation.This mirror is to connect the order negative lens by a slice (or a group) to add a slice (or a group) positive lens formation, its operating distance should equal distance of distinct vision near point, between 250 millimeters to 450 millimeters, enlargement factor can be 1 times to 2 times (focal length should be 250 millimeters to 125 millimeters mutually), and field angle should be greater than 30 degree.Referring to Figure of description

The bathomorphic method of present known control is simple treatment, and this method needn't be spent for a long time and treat, but in use plays the effect that prevents even treat, and saves the plenty of time, can get twice the result with half the effort.

Eyes are in case myopia, wearing spectacles is the compensation to visual debility, can not prevent myopia progression, it is to be noted especially: wearing spectacles goes reading or does the homework, when being engaged in for a long time closely operation, not only unhelpful, myopia is increased the weight of, reason is that near-sighted glasses are a monolithic negative lens, its effect only is to cause beam divergence, reaches the purpose of seeing distant place object clearly, and it is obviously different with the self-control state that does not wear the negative lens eyes to wear negative lens when operation closely, wear negative lens and increased the regulated quantity of eyes, the easier fatigue of eyes relatively.If eyes are in the growth, it is disadvantageous wearing glasses in the distance that eyesight can reach.The reason that these a lot of just people's myopia are constantly deepened.Have only the talent of high myopia to be necessary the wearing spectacles reading, in order that make between object and the eyes distance suitable, wearing spectacles, particularly teenager when the not dark people of myopia then should not be in closely operation relatively.It only is the variation of diopter to the people of low myopia that this method is carried common special eyeglasses, and phenomenon is the corresponding shortening of operating distance.So-called bathomorphic treatment just be to use special eyeglasses closely during operation reasonably the Control work distance diopter is recovered normally gradually, the basis of this method is that eyes are in the middle of the growth, it is long-term therefore treating, and is not suitable for the adult.

When this method just is to make in-plant object to arrive human eye by special eyeglasses in addition is directional light, therefore can overcome the presbyopic difficulty of closely regulating, and is a kind of general presbyopic glasses.

It is to use the photoelectron ranging technology that the side that the present invention controls effective working distance (be photopic vision closely) is sent out, make eyeglass wearer when read-write, the distance of eyes and books less than or all send tangible sound or light signal during greater than effective working distance, the wearer that wakes up correctly uses in control in real time.

Claims

The invention belongs to optical technology, the application aspect near-sighted in vision and control.One. the present invention is a kind of principle, makes teenager's eyes when the read-write books regulate the distance of distinct vision and moves on to the far point by the photopic vision near point, can loosen eyes muscle, eliminates the root that forms myopia.Two. feature of the present invention is to have used special eyeglasses to produce parallel beam, is equivalent to the infinity object when making in-plant object arrive human eye by this mirror, utilizes the method to realize the purpose that control is near-sighted, and as presbyopic purpose.Three. embodying the employed special eyeglasses of this method is to connect the order negative lens by a slice (or a group) to add a slice (or a group) positive lens formation, can be that binocular also can be a monocular instrumnent, system emphasizes to use the parallel and approaching parallel characteristic of outgoing beam, its effective working distance is a distance of distinct vision near point, and enlargement factor is 1-2 times.Four. the present invention has an additional optical electronic range measurement system, make eyes and books the distance for photopic vision closely.
