Glasses

Affiliated technical field

The utility model relates to a kind of optical glasses.

Background technology

Commercially available glasses are made up of optical lens and frame, frame comprises a pince-nez frame and two hangers leg framves, support point is nose and auricle upper limb, by the back summit of constant eyeglass and the vertex distance of cornea, promptly 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).Press the nose glasses to oppress the tissue of neural blood vessel convergent point, acupuncture point and the human body most fragile sensitivity of the nasion two sides for a long time, weight is big and support point is little, very easily causes visual fatigue even skin erosion or pathology.

Commercially available two light and the main leaf of three light microscopic sheets 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, the part picture is lost even is overlapped, and the glasses wearer is caused puzzlement (Xu Guangdi: ophthalmology dioptrics).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.Improve this phenomenon and really be medical personnel's task of top priority.

Though high myopia is autosomal recessive inheritance, still have 40% to be environmental factor, can its expressivity is alleviated or nonpenetrance by the environment adjusting.All there is the brood of supporting in cage to increase the example of myopia in view of Duke-Elder and multidigit scholar, periphery seen the oppressive of function far away and abductor so avoid to reduce with dark color or opaque broadside even with the reflective picture frame closed perimeter visual field than wild survivor.With the eyeglass that glass material is done, the clear illiteracy that do not rise of printing opacity imaging, often have and wear with more than 30 years and do not cause visual fatigue and myopia progression, should affirm the long-term protection of spectacled person's high meticulous eyesight; Unfortunately be difficult for punching, unsettled glasses of the present utility model on the photocentre perpendicular line, reserves aperture be exactly for the ease of the location sight and place fixing rivet/screw etc. and outside side view field abdicate next.Plastic sheet is worn several years normal must renewing, and the spectacled person easily has visual fatigue and other symptom when adapting to again.

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 remove the diagnosis and treatment pseudo-myopia, the teen-age near-sighted overwhelming majority be low medium myopia (＜6.0D), only otherwise force eyes excessively to regulate continuously, be expected to keep not deepening for many years, hyperopia and myopia are normal, long sight tendency after 40 years old occurs, and 50 years old to 70 years old presbyopic progress was regulated the deterioration that descends to 70 years old and stopped.

At present, the domestic and international pince-nez of selling (myopia, presbyopic, special eyes), though the style difference, its framework all needs nose pad and hangers support, the spatial relation of the back focus of its optical mirror slip and people's cornea is static constant all the time.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 nose.Do not proofread and correct ametropia and the sunglasses of sunbonnet is a zero diopter.This spectacle frame structure has not only solved these long-standing problems, also supports an adjustable mobile device, except parallel moving before and after the eyeglass can change the refractive power; Eyeglass tilts also 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, not only is convenient to operative results, and can alleviates the thickness and the weight of eyeglass; That regulates and gather when the prism effect during eccentricity of glasses lens also can be used for solving reading does not claim.The weight that this head rest can be supported can be up to tens of jin, be the pince-nez frame nearly a hundred times.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, so that see the object in the art district center visual field, the big more visual field of enlargement factor is more little, and its interpupillary distance also is unfixed, can't take into account peripheral visual field simultaneously at all, take mirror and could walk.

Embodiment 7: unsettled spectacle frame shown in Figure 9 for the rising and falling of providing that chance that eye muscle loosens and myopia prevention deepen of the student of myopia see mirror far away (as-1.0D～-3.5D), fixed screw promptly about two optical axis witness markers 78,79 beat respectively on the perpendicular line of the optical centre of left and right sides eyeglass in order to finding accurately.Myopia is deepened especially and is worn near-sighted glasses (concavees lens) and see and closely force ciliary muscle excessively to use and peripheral visual acuity and abduction are subjected to constrain relevant, and most of low medium myopia reading need not worn mirror, just see far just and need wear mirror, but because of having put on bad plucking, have to see closely also to gather together and have on, " wear closely see near " causes myopia more, and presses nose to increase the weight of visual fatigue.When using this product, just near-sighted glasses are put down usefulness when the student looks at the blackboard, when reading, mirror up one is lifted and can directly be seen word, avoid ciliary muscle excessively to use and peripheral visual acuity is constrained, so can reduce myopia progression.

With concavees lens change into low convex lens sheet (as+1.0D～+ 1.5D) can be to face and provide anti-rising and falling of usefulness of New Development myopia closely to use mirror with long sight.Face with long sight and see this no problem far away, originally can not wear mirror, but because of seeing that the nearly too many time forces the long-term excessively work of ciliary muscle spasm hypertrophy too for a long time, so can cause New Development myopia, the benefit of this spectacle frame is only to put down seeing closely, avoid ciliary muscle excessively work and spasm hypertrophy, finish watching book up one lift all right.

With concavees lens change into presbyopic lens (as+0.25D～+ 4.5D) can be person in middle and old age to provide the formula of rising and falling to make things convenient for presbyopic glasses, needn't hang on nose and the neck.

This correcting spectacle lens comprises a unsettled spectacle frame of nose, as, head leg frame, head rest, the headstock.This head leg frame meets people's forehead or nose shape, its support point is not which point on the ear, but one of head band and face, so holding power lasting stability, be enough to support and fixing unsettled glasses that the surface level that makes unsettled glasses and the front surface of eye keep parallel from being close to (seeing far away) to less than 5～15 angles of spending (take a fancy to, closely).

Thisly lift the adjustable link of landing up and down, for myopia provides " lifting eyeglass sees closely ", " putting down eyeglass sees far " along the eye face; The convenience of " putting down eyeglass sees closely ", " lifting eyeglass sees far " is provided for long sight.

The glasses of this correction of refractive errors, its feature also are to comprise on described lens and/or the spectacle frame photocentre sign of a lenses or pupil sign and find accurately when wearing, as a point, and hole, crack, lines, scale, mark, or any mark.The size and the pin hole mirror of aperture are suitable, and diameter is about 1mm.Described witness marker preferably is positioned on the perpendicular line at lens optical center, and horizontal line takes second place.

Make on the optical centre of this product lenses and its fixed frame with the right left aperture sign of similar pin hole mirror suitable, can help the spectacled person to find comfortable far and near interpupillary distance at any time voluntarily according to job requirement and custom distance, when seeing distant place target just by the homonymy aperture respectively with right eye and left eye, illustrate that the aperture sign is positioned at this just and watches on the sight line far away, when then the distance that saves these two aperture signs with hand adjustment makes eyes can see this distant place target simultaneously, what the distance of these two aperture signs was this spectacled person checks to see interpupillary distance far away certainly, can give fixing; See that nearly interpupillary distance is with seeing that close-target gets final product.The position of the eyeglass of this glasses punching from then on needn't be at the nose pad and the hangers place of eyeglass both sides, but directly at the perpendicular line of the optical centre of eyeglass, on horizontal line or the astigmatism axle, people's a glance just can be seen clearly, is beneficial to the identical of pupil sight line and lens optical center.

In order to make the spectacle frame of a secondary comfortable wearing, the number of degrees of lenses not only, astigmatism axle, and interpupillary distance (sight line apart from) must be accurately also should make the lens minute surface and the angle between the surface is closely parallel at the moment, and between-5～+ 12 degree, average is about 0～12 degree.

When this technology of application, the product example is can be vicissitudinous, as: a kind of unsettled glasses of head rest formula with the optical lens correction of refractive errors.The adjustable multi-focus lens glasses of sound attitude that a kind of imitative crystal sound attitude is regulated.A kind of glasses that tilt to improve the astigmatism and the lens thickness weight of high myopia with eyeglass.A kind of student reduces that myopia deepens look at the blackboard rise and fall the myopia mirror holder (2.0～-4.0D).A kind of face or slight long sight for the reading of anti-New Development myopia with rising and falling spectacle frame, minuent is equipped with in the front lower place, joint, the place ahead of its head rest, and (1.0～1.5D) convex lens put down during reading, pick up when not reading, with minimizing New Development myopia.

Characteristics of the present invention are simple in structure, do not have the main leaf of two light or three light and sub-sheet or gradual central authorities excessively arrowband and peripheral astigmatism, saved open complete sum binocular stereo vision true continuously in the physiology visual field to greatest extent from damage, distinguish the apparent efficiency height, wear and use nature and unfold, easy to use.

Be with the fundamental difference of commercially available two light, three light, multi-focus lens, the latter is making diopter and focus more than two by changing lens curve on single the optical mirror slip, thereby single burnt mirror is become how burnt mirror, be intended to adapt to the spectacled person and moving the dynamic need when sighting target and sight line with many light microscopics sheet of having fixed; And this product is not many light but single vision lenses, be that the position of single lens sheet on optical axis moved and made its refractive power and focus be regulated variation, this dynamically to move the more commercially available static glasses of the method for dealing with spectacled person's dynamic need more near the adjusting physiology of people's crystal, She Ji new construction has broken through static glasses to the long-term compressing of vulnerable areas with the moving technology confinement of quiet gram thus.The finishing of this dynamic adjustments depends on special a made optical mirror slip new components of shift position repeatedly on the optical axis, the many focuses of single eyeglass furnishing.This move needs half second approximately, regulates in required half second very approaching naturally with people's crystalloid.This new moving-member depends on the support of head, temples and/or neck portion and brings improved new purposes for traditional neck band and clamp.

Embodiment 8: Figure 10 shows the user mode that the pince-nez framework is changed into the unsettled glasses of nose clip, nose pad.On the adjustable link of articulated type is arranged, the adjustable multifocal spectacles of bionical reason dynamic adjustments is provided for person in middle and old age.The joint is moved and can be changed described optical mirror slip the position of eyeball is changed its diopter to eye, as the number of degrees of concave-sphere, and the number of degrees of post mirror and axle position, the number of degrees of prism and direction, the astigmatism that eyeglass tilts to be improved also reduces lens thickness and weight.Can improve one in the wound healing process of brilliant underlying mass excision back when eyeglass leans forward and cross property level astigmatism, be convenient to operative results, and can alleviate the thickness and the weight of eyeglass; That regulates and gather when the prism effect during eccentricity of glasses lens also can be used for solving reading does not claim.The weight that this head rest can be supported can be up to tens of jin, be the pince-nez frame nearly a hundred times.

Embodiment 9: Figure 11 shows the user mode of unsettled glasses.On the adjustable link of fence type is arranged, its slip near-end can directly be fixed on the optical mirror slip.Fixing as on the photocentre perpendicular line of eyeglass, being equivalent to eyelid covering place punching, or be fixed on the spectacle-frame that optical mirror slip is housed, or directly be integral with mould.Described adjustable link changes diopter by the relative position that move to change described optical mirror slip and eyeball on optical axis, thus the image that makes the different distance object all on the retina of eyeground imaging place focused on, become clearly as.Moving range is about about 12～35mm, just in the auxiliary scope of seeing nearly required adjusting (+0.25D～+ about 3.50D).

When advancing, the optical centre of eyeglass will match with the optical axis of eye (positive photocentre), does not make the light generation deflection that enters intraocular, and interpupillary distance is measured to be needed accurately.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 will produce 1 collecting and distributing deviation as every inclined to one side 1mm.Every pair of glasses all will be measured optical centre, and far away, in, nearly three main positions all install suitably, and its optical centre and the optical axis of eye are matched, regulate and gather balance.

The general idea of 10. products of embodiment is that nose is unsettled, is convenient to the open and bionical reason dynamic adjustments of peripheral visual field.This design also is suitable for the adjustable unsettled artificial lenses of diopter, as, place a shape to be equivalent to the mould of an optical lens liquid phase of a mushy stage two-phase light penetrating object, the outside surface that adds thermocoagulation or this liquid phase of chemocoagulation makes it to form solid-state cyst membrane, the strength of solidifying from outside go up, the center inwardly do not wait down, cause the cyst membrane thickness not wait, cause wherein liquid under hydraulic pressure, when reading a book mobile eyeball, or when heating up through the weakness of cyst membrane to front protrusion, the dynamic adjustments of analogue crystals thus.
