Mechanism of the present invention:
1, head position, sitting posture bad cause the cervical spondylopathy problem and with the analysis of eyesight relation
Human cervical vertebra has a physiological bending backward normally, it is the most healthy head position, figure that new line is squared one's shoulders, and nearly work is seen in a large amount of reading and writing now, force that the people bows, hunchback, cause the unusual back-flexing of cervical vertebra or distortion, the compressing or involve tissues such as some peripheral nerves, blood vessel, vertebra, spinal cord and muscle, so can form many cervical vertebra relevant diseases for a long time.In addition, generation, development and the sitting posture of overwhelming majority myopia are closely related.In general, head position, sitting posture is bad is the reason that causes myopia.From another perspective, people's vision need see clearly Chu, seeing clearly is people's a kind of instinct and demand, and the requirement of seeing clearly is more big, and unmanageable instinct is also more strong, this instinct of looking has clearly caused the bad of head position and sitting posture, has also more increased the weight of poor sight and myopia generation, development.So, control myopia, one can be directly from forcing correction head position, sitting posture to be started with; Two the more important thing is and should start with from satisfying, be obedient to the instinct that the people is badly in need of seeing clearly, act in a diametrically opposite way.Namely make earlier confusion region (non-field of regard) and clear relatively and comfortable district (entangling the appearance field of regard) artificially, force the people to go read fortune to clear district by the light of nature, avoid the confusion region, like this through particular design, can adjust sitting posture by vision, the step-down head is corrected head position and a sitting posture for coming back (having met the normal bending of human cervical vertebra) or can not hanging down first-classly thereby reach effectively, also reaches inhibitions, recovery, treatment, the purpose of myopia prevention in advance simultaneously.
2, near-sighted Analysis on Mechanism
1), out of focus (namely defocusing) reason
Nearly decades, animal out of focus (defocusing) experimental papers about causes of myopia had a lot, a large amount of statistical data in conjunction with near-sighted epidemic disease and behavior relation, can reductive analysis be to see closely or wear the long sight out of focus that concavees lens cause inside ofeye central field of vision or peripheral visual field, myopia that this out of focus can form structural (axle property), otherwise wear the myopia out of focus that convex lens cause inside ofeye central field of vision or peripheral visual field, long sight that this out of focus can form structural (axle property).Theoretical foundation thus, must solve the problem of seeing nearly this long sight out of focus as can be known, for the people, because the people looks instinct clearly and the near demand of taking temperature greatly, so, the long sight out of focus that will overcome the central field of vision district of seeing near change people exactly is myopia out of focus problem (central field of vision district refer to macular area or near the surrounding zone of macular area), can only carry out the myopia out of focus of the intervention creation whole visual field of optical articles like this to retina, it is general orientation and the way that solves the axial myopia development even reverse myopia.
2), intraocular pressure reason
According to up-to-date scientific research data, experimental papers and clinical statistics, bathomorphic development and intraocular pressure are in close relations.When seeing that closely mistake was near (in 25 centimetres), intraocular pressure can raise, its reason with see when near eyes start regulate burden greatly should be relevant, looking when closely too small of eyes, the outer flesh of eye is more and more nervous, can act on the eyeball outside, increase intraocular pressure, and the interior flesh of eye is also more and more nervous, comprises ciliary muscle, and effect such as the muscle group in the iris can influence the unobstructed property of the discharge of room, eyes front and back liquid, and cause the increase of intraocular pressure, and this pressure can be delivered to the weakest back utmost point portion of eyeball, causes expansion and biochemical variation of back utmost point portion, forms axial myopia, even detachment of retina, need to start with from sighting distance and adjusting so reduce pressure, avoid looking the hypotelorism of thing and the adjusting set of seeing nearly property of minimizing eye etc., the intraocular pressure of avoiding raising is another way of control myopia progression.
3), regulate reason
The people closely will have a series of many-sided adjustings soon, can be called comprehensive adjusting, adjusting comprises that lenticular dioptric changes, the variation of intraocular pressure, the contraction of the adjusting of extraocular muscle and intraocular flesh and structural deformation (known have an iris, the fine motion reach of ciliary muscle, cornea and lenticular deformation, also has the deformation of eyeball integral body, the variation that the axis oculi modulability is small), so regulating is the overall variation of a comprehensive complexity, and the purpose of this adjusting is to be suitable for seeing near needs, so in the course of time inevitable one-piece construction changes to near-sighted structure aspects, and regulate the out of focus that depends mainly on foveal region of retina, also have the binocular integration of different distance.Avoiding seeing near adjusting and reach reverse adjusting by the myopia out of focus of center, in conjunction with distance control, avoid excessive comprehensive adjusting, is the method for every aspect to the eye structure control myopia that plays favourable help and the scheme of design.
Above-mentioned 3 factors are all closely related with distance and light, the optical imagery situation that namely is decided by amphiblestroid macula lutea place, above-mentioned factor may be again unified to a root, it is the factor of light, enter the eyes coking with the light of difference degree of diverging to and (the myopia out of focus takes place namely in macula retinae district diverse location, positive burnt, the long sight out of focus), cause that eyes just, anti-adjusting, every aspect just in the size variation of intraocular pressure and the eyeball, anti-change and even ocular tissue's physics and biochemical variation, summarizing popular saying is exactly to see closely excessively to cause myopia, myopia is the bad variation of ocular structure, the most obvious place is that axis oculi is long partially, back utmost point portion's peripapillary scleral ectasia and linked groups's structure thin, also have ciliary muscle to change, crystalline lens displacement and variation, varieties of intraocular pressure, ambitus long sight out of focus etc., wherein the constructive variations majority is irreversible, but the eyes basis is seen needs far away and compensatory growth variation, can remedy the defective that has taken place again to structural change from adjusting and tissue growth again, so, vision restoration also is fully possible, the method that the best way is still intervened with optical articles, and the degree of divergence of light is decided by the distance of light source, divergence increases (non-directly proportional level numerical expression increases) rapidly during hypotelorism, also can be understood as the nearly time becomes greatly rapidly in amphiblestroid long sight out of focus, causes myopia to be easy to take place and develop.So the distance relevant with light is again crucial, to control distance (beyond 25 centimetres) well be crucial so prevent and treat myopia, this distance again with solve sitting posture, the head position is bad, relation is maximum.
In a word, solve near-sighted problem, will solve the problem of distance and light exactly, solve exactly and excessively see near problem, namely prevent long sight out of focus and the problem of excessively regulating, and then be again the problem that solves sitting posture head position.Generally speaking, head position, sitting posture can solve the most nearly comprehensive adjusting of excessively seeing, near distance was not was not read and write in control, as adding the suitable optics out of focus eyeglass of configuration and distance dependent again, just more can guarantee to reach the target that the intraocular that needs becomes the myopia defocused image, prevention, the near-sighted effect of healing can be better, even can thoroughly recover eyesight.
According to above-mentioned theory and analysis, the present invention has designed the blocked area at glasses and (or has claimed non-field of regard, as follows) and field of regard, utilizing the blocked area to hinder and see closely or cross and closely see, effect is to prevent that retina generation long sight out of focus and the excessive comprehensive adjusting of eye and intraocular pressure from increasing.The blocked area can be that its effect of convex lens is the whole retina myopia out of focus that produces optics, and the foveal region of retina district is big out of focus relatively, hinders eyesight; Also can be that not reflective and lighttight material hinders eyesight.Utilize field of regard attraction sight line and then correct head position and a sitting posture, control is seen and is closely prevented from excessively seeing closely, control myopia; And can guarantee to produce the medium and small out of focus of foveal region of retina district myopia better, strengthen the near-sighted effect of control.
The invention has the beneficial effects as follows: by control head position and sitting posture, make the wearer form a better learning, work, daily life eye custom, thereby myopia is played good restraining, recovery or prevention effect; Simultaneously, to wearer's torticollis, faulty posture such as bow, overlook, look side ways, crouch down and play good role of correcting, can prevent the generation of many cervical vertebra relevant diseases; The present invention is simple in structure, does not need any auxiliary equipment, and is easy to use, control myopia and effective, the instant effect of correction faulty posture.The present invention is simple in structure, principle science, uniqueness, has solved the key issue that causes myopia, and effect is remarkable.Be particularly suitable for juvenile shortsightedness prevention, treat and entangle appearance.
In addition, by guaranteeing to produce myopia (middle or small) out of focus in foveal region of retina district, amphiblestroid center is changed to the direction that axis oculi dwindles, thereby more effectively play myopia and prevention effect.Field of regard can not only play control head position and sitting posture effect indirectly, also can play to prevent that the foveal region of retina district from producing the long sight out of focus.But not field of regard if can produce the big out of focus of myopia to retina, and it is better then to prevent and treat near-sighted effect.
Glasses only are provided with the bottom and entangle the long-time reading and writing etc. of being specifically designed to of appearance field of regard and see control myopia under the nearly situation and entangle appearance and use and be used for changing and be accustomed to the behavior of bowing.Have only top to entangle being specifically designed to of appearance field of regard and see time control myopia far away and entangle appearance and use, if in the classroom, listen class hour to use, the generation of seeing nearly behavior such as then can prevent from bowing, overlooking.Be provided with the bottom simultaneously and entangle appearance field of regard and top and entangle the appearance field of regard, be specifically designed to occasion control myopia and entangle appearance and use such as give a lesson, pay attention to the class, take notes, see in the time of can satisfying study and to see that far inbreeding replaces the needs of use.

2, this table institute's specific height of the part of classifying as, see nearly posture to rectify the back distance be 33.3 centimetres, see far away from 5 meters and student, age in addition to be that 6～16 years old, different near-sighted degree are joined mirror and used one month effect table.
3, use testing result after one month with back eyesight raising and effect for control person described in the table.
4, standard excellent, good in the table, that can, differ from is:
Excellent: improve more than several 3 row with the back eyesight, near-sighted diopter reduces more than-100 degree.
Very: improve several 2 to 3 row with the back eyesight, near-sighted diopter reduces by-50 to-100 degree.
Can: improve several 0 to 1 row with the back eyesight, near-sighted diopter reduces by-25 to-50 degree.
Difference: do not improve with the back eyesight, near-sighted diopter does not take a turn for the better or increases the number of degrees.
5, the result of use in Fig. 6, Fig. 7, totally 30 specific embodiments shown in Figure 8 is in the table: used 1 month, sitting posture, a head bad problem are corrected substantially, and myopia or myopia progression phenomenon do not take place.
Two, use clinical trial situation report of the present invention
One), 564 routine A nearsighted persons use clinical trial situation report of the present invention (using 6 months statisticses):
(1), experiment crowd
Select elementary and middle school students, at 6～16 years old age, 11.5 years old mean age, number 564 people get rid of the person of mismatching, often dye look Hyperlink sex-controlled inheritance person (or the equal high myopia person of father and mother), pseudo-myopia person.
(2), experimental technique
Join the mirror method: entangle appearance field of regard and non-field of regard by summary of the invention requirement and actual needs design, entangle the appearance field of regard and can join mirror (can join concave cylindrical lens, projection lens, prism etc. by prior art for astigmatism, squinter) by the configuration parameter formula of medium and small out of focus eyeglass.
Everyone carries out Integrated Checkout: sitting posture, a head problem investigation records, computerized optometry, inspection shadow are determined the near-sighted number of degrees, the accurate eyesight of mark, interpupillary distance, eye position height, health height and reasonable sighting distance.Join various glasses of the present invention according to data and needs.For eyesight better as 0.6 people or do not see student far away joins and see nearly mirror such as Fig. 2; Below 0.6, myopia is joined and is seen far away, near Twopurpose mirror such as Fig. 3 and Fig. 5 at people's classroom learning of middle and high degree for eyesight; Listen to the teacher, see that myope far away, that the custom of bowing is arranged is joined sees mirror far away such as Fig. 1; What custom was bowed can also join life with seeing mirror far away such as Fig. 4; Like seeing that can also joining of computer is middle apart from using mirror such as Fig. 2.Use after 1 to 2 months, carry out near-sighted diopter and measure myopia minimizing-0.5D and above person, join mirror again once; Computerized optometry after half a year, inspection shadow are determined the near-sighted number of degrees, standard vision mensuration.That adds up after half a year the results are shown in Table 2 and table 3.
The random sampling groups of people, carrying out mensuration such as an A is super, axis oculi checks, contrast shows does not have bad development problem, half a year measurement result and the impression of inquiry real life, study, display effect is good, diopter and eyesight improve stable, the intended purposes that has reached the development of control adolescent myopia and to a certain degree recovered.
(3), prevent and treat near-sighted effect standard
Cure: naked eyesight reaches more than 1.0 and 1.0; The complete obiteration of myopia symptom.
Special efficacy: computerized optometry takes a turn for the better, and more than inspection shadow diopter minimizing-1.00D reached, UCVA promoted 〉=3 row;
Effectively: computerized optometry takes a turn for the better, naked raising 〉=1 row (＜3 row) of looking, and inspection shadow diopter minimizing-0.50D and above arriving-below the 1.00D.
Invalid: computerized optometry diopter development, inspection shadow diopter descends, and nakedly looks decline.
(4) statistical effect
Originally ubiquity bowing in various degree, the bad problem of sitting posture during student's study have thoroughly solved sitting posture, head position problem after using half a year, and the user is corrected to proper degree very significantly.
1, entangles the appearance statistical effect and see Table 2.
Use to observe and entangle appearance statistical effect table table 2 half a year
2, the myopia preventing and treating statistical effect sees Table 3.
564 people (several 1128 of total eye) use eyesight statistical effect table table 3 half a year
Two), normal eye and slight myope are worn simple penetrating hole or plano lens formula situation and statistical effect result:
Normal eye and slight myope are worn simple penetrating cellular type mirror experimenter 36 people, use statistics half a year, and sitting posture, the bad problem in head position are all corrected, and myopia and myopia progression phenomenon do not take place.
The present invention is divided into the corresponding eyes of glasses and can not sees the district relatively clearly and can see the district clearly with relative, utilization can not be seen district's obstruction clearly and see near, utilization can be seen adjustment head position, district clearly and control indirectly and see closely, the degree of divergence manufacturing out of focus that changes light by command range recycling optical means has just had guarantee, improved effect, thereby the solution sitting posture, head position and near-sighted problem.Generally can not see the district is fixed on eye pupil by glasses dead ahead clearly, be arranged in the district of glasses and on every side, can see clearly relatively the district by eyeglass design be fixed on eye pupil above or below, can not see the district clearly and adopt various printing opacities, light tight, semi transparent material, the eyeglass that adds functional membrane, the optical material of broad sense or do not have eyeglass or flat mirror, its effect is that different relatively dioptric eyes rise and stop the eyesight influence sharpness or do not have vision (such as black completely), the light action of long sight out of focus can not take place retina, any healthy negative interaction that affects one's power of vision can not be arranged (such as the material that diffuse reflection or white are arranged, it is equivalent to nearly thing, block pupil and can produce retina long sight out of focus image, cause myopia progression, other have diffuse reflection to have the color material also inadvisable).Can see the district relatively clearly and adopt various optical mirror slips for eyes or do not have eyeglass, its effect is that can not to see the district relatively clearly be clearly, can see.And change head position, can not too closely or can only seeing of seeing when making eyes read-write study is far away, thereby central retina is reduced the chance that the long sight out of focus takes place as far as possible, reaches command range like this, correcting sitting postures, the effect of maintenance vision health and control myopia.Therefore, have torticollis, bow, myopia and the relevant issues prevention effect is good, instant effect, effect stability, characteristics easy to use.
