Description
Affiliated technical field
The present invention relates to a kind of method and Glasses structure of adjustable multifocal spectacles.
Background technology
Commercially available glasses are made up of optical lens and pince-nez framework, support point is nose and auricle upper limb, thereby the vertex distance that makes the back summit of eyeglass and cornea keeps constant, and frame is that the spatial relationship by constant lens and spectacled person realizes the glasses function.This point is even the gradual multifocal spectacles in six generations of the first generation to the no exception (exhale the Zhenglin: practical Progressive eyeglasses is learned).The weight of glasses has been oppressed the tissue of neural blood vessel convergent point, acupuncture point and human body most fragile sensitivity on the nasion two sides, temples, the ear, and weight is big and support point is little, very easily causes visual fatigue even pathology.
The main leaf of commercially available Bifocal lenses and the produced leap of sub-sheet, image-jumping phenomenon and corresponding defect of visual field laterally move during reading and can produce extra dispersion differences and rainbow effect, and the glasses wearer is caused puzzlement (Xu Guangdi: ophthalmology dioptrics).The picture jumping that three light microscopics also have mirror degree bridging phenomenon and produce therefrom, the part picture is lost even overlapping puzzlement.
Though commercially available gradual multifocal spectacles is crossed at the mirror degree that has solved simultaneously on the same eyeglass between multifocal vision correction and many diopters, but can not overcome between many diopters springing up phenomenon and revolving dizzyly of conversion continuously, and central authorities excessively are with narrow and peripheral astigmatism also to have much room for improvement.
Myopia especially is pilosity among China, Japan and the Jew in country many with eye, that have a civilization of long standing.Rose 48.4%, 54.2%, 60.0% and 67.8% every year respectively after the rate of myopia of Shanghai medical university was entered a school from new life, and rise to 73.9% gradually.Zhu Xuemin shows that to the statistics of 66,655 eyes of 24 hospitals the myopia and the ratio of long sight are 2.15: 1.These reports strike the eye and rouse the mind really, how to improve this phenomenon and really are medical personnel's task of top priority.
Though high myopia is autosomal recessive inheritance, its expressivity is alleviated even nonpenetrance but still can regulate by environment.All there is the brood of supporting in cage increase the example of myopia in view of Duke-Elder and multidigit scholar, avoids also can reducing harm eye with the visual field of unclear eyeglass and big opaque frame sealing than wild survivor.
Investigation in 1986 such as Wang Fangrun shows, but the tendency of early prediction refraction of eye degree is as the control reference, if eye ametropia force＞2D after 6 years old mostly is pathological hypermetropia; If eye ametropia force＜1.5D after 6 years old mostly is and faces or long sight.In addition removing the diagnosis and treatment pseudo-myopia, the teen-age near-sighted overwhelming majority is low medium myopia, and diopter does not generally have obvious eyeground and changes below 6.0D, and it is yet normal to correct defects of vision.Only otherwise force eyes excessively to regulate continuously, be expected to keep the several years not deepen, hyperopia and myopia are normal, and the long sight tendency after 40 years old occurs, 50 years old to 70 years old presbyopic progress, and the deterioration process that descends to 70 years old adjusting power stops.
At present, the domestic and international glasses of selling (myopia, presbyopic, sunglasses, special eyes), though style is ever-changing, the requirement of support point does not change on the pince-nez of its framework and the ear.The spatial relation of the back focus of its optical mirror slip and people's cornea is static constant all the time.The weight of glasses has been oppressed the tissue of neural blood vessel convergent point, opticoel and human body most fragile sensitivity on the nasion two sides, temples, the ear.The big support point of weight is little and fragile, causes visual fatigue even pathology easily, the time be easy to slippage in rapid movement and swimming and have to add headband in addition and fix, and the tractive of headband has more increased the weight of the compressing to above tissue.And new Glasses structure has not only solved this long-standing problem, can also stably support mobile device and easily adjusting.The benefit of this easy adjusting can change the refractive power except parallel moving before and after the eyeglass; Eyeglass tilts can help improve astigmatism, improves one in the wound healing process of brilliant underlying mass excision back when leaning forward as eyeglass and crosses property level astigmatism; That regulates and gather when the prism effect during eccentricity of glasses lens is expected to solve reading does not claim.
Though on the operating table also with the fixing frontal mirror of browband, but its frontal mirror eyeglass is to replace the expensive surgical operation microscope of the eighteenth of the twenty with magnifier, in order that see the object of field of operation central field of vision, the big more visual field of enlargement factor is more little, can't take into account peripheral visual field simultaneously at all, take mirror and could walk.
Summary of the invention
In order to overcome the deficiency of existing glasses frame structure, the invention provides a kind of method and Glasses structure of adjustable multifocal spectacles, comprise an energy raises telescope direct sheet distance at same optical axis adjustable link and a browband of supporting these parts.The technique effect of this adjustable link is the distance of mobile optical eyeglass on former optical axis, and the technique effect of this browband is the connection of supporting this adjustable link, liberates the compressing of commercially available glasses to nose temporo ear sensitizing range.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of adjustable multifocal spectacles: on an optical axis mobile optical eyeglass change image that distance with eyeball makes the different distance object all on the retina of eyeground imaging place focused on, become clearly as.
Comprise an adjustable link, the head end of described adjustable link is fixed on endless belt, cassette tape or the clamp of people's head or forehead, and the sliding part of described adjustable link is fixed on the optical mirror slip; The image of described adjustable link by making the different distance object at the relative position that move to change described optical mirror slip and eyeball on the optical axis all on the retina of eyeground imaging place focused on, become clearly as.
When advancing, the optical centre of eyeglass must match with the optical axis of eye (positive photocentre), does not make the light generation deflection that enters intraocular, and interpupillary distance is measured the sight line that should use Xu Guang Di Shi and measured the used finger coreometry of replacement apart from method or iris corder.Because light can produce the prism effect by non-photocentre part, the prism effect of the big more generation of the number of degrees of eyeglass is also strong more.The lens of one-10 degree as the collecting and distributing deviation that every inclined to one side 1mm will produce 1 °, must be avoided.Every pair of glasses all will be measured optical centre, and far away, in, nearly three positions all install suitably, and its optical centre and the optical axis of eye are matched, regulate and gather balance, unfold.
The invention has the beneficial effects as follows simple in structure, the main leaf and sub-sheet or gradual excessive arrowband of central authorities and the peripheral astigmatism that do not have two light or three light, open and binocular stereo vision continuously true of having saved the physiology visual field to greatest extent from damage, distinguish the apparent efficiency height, wear the posture of usefulness and adapt to more natural and free.
Be that with two, three commercially available light, the fundamental difference of many focuses mirror commercially available many focuses mirror is the diopter and the focus of making more than two, promptly single optical mirror slip itself is become how burnt mirror on a single optical mirror slip; Move its refractive power and focus are regulated and this product is the position of same single vision lenses on optical axis.
