Description

Set lens, set glasses and uses thereof
Technical field
The present invention relates to the optometric technology field, relate to the glasses that (normotopia eyes) such as emmetropia, myopia, farsightedness, presbyopias use.Lens of the present invention is the preparation burr lens used of glasses of the present invention or the lens to be installed that has been shaped.
Background technology
Presbyopia glasses of the prior art or spectacles or spectacles for long sight all are the glasses of change regulating, and shortcoming is the set (seeing Fig. 1, Fig. 2) that the adjusting that only changes eyes does not but change eyes.Binocular integration is felt uncomfortable and easy fatigue with cooperating with the excessive eyes that will make of custom gap of adjusting when wearing with glasses.Common phenomenon for example: at the presbyopia glasses of putting on prior art or the initial stage of spectacles, because the custom (see figure 3) that has cooperated between glasses have destroyed eyes original set and regulated, so can feel uncomfortable and easy fatigue, wear glasses for a long time and could adapt to after forming new custom (see figure 4), but remove glasses and see that with bore hole thing can feel uncomfortable because of having destroyed new custom again, though this moment, myopia watched that nearly thing does not need to wear spectacles and just can see clearly, extract the glasses of being accustomed to wearing and can feel uncomfortable and easy to be tired.Cooperate custom between prior art " ZL95201944.2 eyesight return mirror " has been destroyed the original set of eyes equally and regulated, enlarged the contradiction of set and adjusting, can not allow eyes when watching, feel comfortable enduring hardships.
Summary of the invention
The purpose that the present invention gathers glasses is to improve set and the matching relationship of regulating by changing set, allows eyes feel comfortable indefatigability when watching.
The design that the present invention gathers glasses is to utilize " set lens " to change set, eyes are regulated the contradiction (Fig. 7) with set when improving custom and often wearing the human bore hole of spectacles and see nearly thing, or are used with the presbyopia glasses of prior art or spectacles and improve its shortcoming (Fig. 5, Fig. 6).Technical solution of the present invention is: " (1) a kind of set glasses ", the spectacle frame that lens and crutch glasses sheet are arranged, be characterised in that lens is that " set lens " (illustrate: " set lens " is different with " adjusting lens ", regulating lens is to change the poly-of light to loose, the set lens mainly is the direction that changes light, changes the poly-of light hardly and looses." set lens " can be the achromatism refracting prisms, or the on-plane surface refracting prisms, or refracting prisms such as plane refraction prism), the lens of corresponding eyes is symmetrical two refracting prisms.The angle of deviation equal and opposite in direction of these two refracting prisms or approximately equal, substrate can be all inwardly or all outwards or all inwardly on the lower side or all inwardly on the upper side or all outwards on the lower side or all outwards on the upper side, these two refracting prisms can be two bodies separately, also can be to fuse.Other glasses can be installed on this set glasses and (to illustrate: when the spectacle frame that refers to gather glasses is a spectacle frame commonly used, on other old (closely) glasses, there is union piece other old (closely) glasses can be connected on this set glasses), perhaps have on this set glasses and this set glasses are connected to union piece on another one presbyopia glasses or spectacles for long sight or the spectacles (union piece can be a hook, or spring clip, or magnet, or the grafting part or the like), perhaps gather still to leave on the glasses empty position that two other regulates lens (being convex lens lens or concavees lens lens) can be installed.The purposes of " (1) set glasses " is to improve the consolidation function of presbyopia glasses or spectacles, and perhaps (spectacle frame is the set glasses of spectacle frame commonly used) is the presbyopia glasses that use as the custom person's bore hole of often wearing spectacles or closely uses glasses.But in above-mentioned " (1) set glasses ", do not comprise " adjusting glasses " such as presbyopia glasses, spectacles for long sight, spectacles, do not comprise " adjusting lenses " such as convex lens or concavees lens yet.
Additional technical feature of the present invention is as follows: (2), above-mentioned " (1) set glasses " is to be the glasses of eyeglass with refracting prisms (promptly gathering lens), on the basis of above-mentioned " (1) set glasses ", increase spectacles, comprise the adjusting glasses in the set glasses, the set glasses are Two-layer spectacles, spectacles in the Two-layer spectacle be to be to live in being connected between the glasses of eyeglass with refracting prisms, can separate or use separately, the substrate of refracting prisms all outwardly.(3), in above-mentioned " (1) set glasses ", increase by two myopia eyeglasses, promptly be equivalent to gather and comprise spectacles in the glasses, the substrate of refracting prisms all outwardly, two myopia eyeglasses (concavees lens) diopter equates (no matter the far point of user's eyes is identical or gap is bigger, the diopter of two eyeglasses all equates).(4), increase the presbyopia glasses (or spectacles for long sight) of prior art on the basis of above-mentioned " (1) set glasses ", comprise presbyopia glasses (or spectacles for long sight) in the set glasses, the set glasses are Two-layer spectacles; Presbyopia glasses (or spectacles for long sight) in the Two-layer spectacle be to be to live in being connected between the glasses (both " (1) set glasses ") of eyeglass with refracting prisms, can separately use, also can unite use, the substrate of refracting prisms is all descended inwardly or is all gone up inwardly inwardly or all.The diopter of two convex lens sheets of presbyopia glasses (or spectacles for long sight) equates (no matter the far point of user's eyes is identical or gap is bigger, the diopter of two eyeglasses all equates) (5), corresponding eyes increase by two convex lens lenses in above-mentioned " (1) set glasses ", promptly in the set glasses, comprising presbyopia glasses (or spectacles for long sight), glasses and the presbyopia glasses (or spectacles for long sight) that with refracting prisms are eyeglass be combined into one (refracting prisms preceding near observing thing convex lens in the back during near eyes effect better, refracting prisms also can the back but effect is relatively poor), the substrate of refracting prisms is all descended inwardly or all inwardly, the diopter of two convex lens sheets equates (no matter two far point is identical or different, the diopter of two eyeglasses all equates).And directional light by the set glasses left side refracting prisms and the formed focus of convex lens on the left side and directional light by the right refracting prisms and the formed focus of convex lens on the right between apart from less than 3 centimetres.Perhaps, two focuses about after directional light is by " (1) set glasses " and presbyopia glasses, can forming, distance should be less than 3 centimetres between these two focuses.(for example: shown in Figure 8).(6), upward increase by two adjusting lenses (referring to convex lens lens or concavees lens lens) that diopter is identical at above-mentioned " (1) set glasses ", the set glasses are will change the glasses of set and change the glasses of regulating to be combined into glasses.And with glasses during over against directional light, directional light overlaps by the formed focus of the sight glass of right eye with directional light by the formed focus of sight glass of set glasses left eye, two real focus of glasses overlap (for example Fig. 9 or shown in Figure 11) when two adjusting lenses are two convex lens, are that two virtual focuses of glasses overlap (see figure 10)s when two lens sheets are two concavees lens.(7), in above-mentioned " (1) set glasses ", increase by two and regulate lens (referring to presbyopia eyeglass or near-sighted glasses lens), and the structure of spectacle frame is to adjust the adjustable mirror holder of glasses focal position, about adjusting glasses and making directional light by the set glasses behind two sight glasss the distance between formed two focuses change or this two focuses overlapped.The structure that just refers to spectacle frame be can the rotating prism substrate towards mirror holder, or spectacle frame is the mirror holder that can change two optical center of lens distances, or spectacle frame is the mirror holder that can change distance between refracting prisms and the lens, or spectacle frame is the mirror holder that can change eyeglass.(8) in above-mentioned " (1) set glasses ", increase by two and regulate lens (being convex lens lens or concavees lens lens), the diopter of the adjusting lens of corresponding left eye approximates " 1/ the left eyeglass lens diopter of the spectacles worn of viewing distance+custom " farthest, and the diopter of the adjusting lens of corresponding right eye approximates " 1/ the right eye eyeglass diopter of the spectacles worn of viewing distance+custom " farthest.Convex lens lens diopter just is, concavees lens lens diopter is negative.And the substrate of two refracting prisms is at inboard (on " in the inboard " basidigitale is all inside or all inwardly following or all inside).The size of the horizontal component of refracting prisms angle of deviation approximates " spectacles that arcsin[custom is worn about two optical center of lens spacing/2 (viewing distance-front and back two DBLs farthest)] ", front and back two DBLs are refracting prisms and the distance of regulating lens (two DBLs before and after should as far as possible reducing during the design glasses, prism in preceding spacing for just, in the back spacing is negative), the angle of deviation equal and opposite in direction of left and right sides refracting prisms, substrate is oriented left-right symmetric, in the set glasses two spectacles of regulating that lens photocentre spacing can equal or wearing near custom about two optical center of lens spacings.The observation thing is less than or equal to viewing distance farthest to the distance of eyes during use.These set glasses be the person that is accustomed to often wearing spectacles use closely with glasses or presbyopia glasses.Image is on the far point when object distance equals farthest viewing distance, when object distance during less than viewing distance farthest image in the far point.When " right eye eyeglass diopter=1/ of the spectacles that the left eyeglass lens diopter=custom is worn of the spectacles that custom is worn is viewing distance farthest ", diopter=0 of the adjusting lens of the diopter=corresponding right eye of the adjusting lens of corresponding left eye, the set glasses are equivalent to have only the refracting prisms glasses and do not have lens, just " the set glasses with spectacle frame commonly used " in " (1) set glasses ".(9), two presbyopia eyeglasses of increase in above-mentioned " (1) set glasses " are promptly gathered and are comprised in the glasses that two correspondences the presbyopia eyeglass of eyes, and the diopter of these two presbyopia eyeglasses is unequal, refracting prisms left-right symmetric, substrate are all descended inwardly or all inwardly.These two presbyopia eyeglasses want its diopter of far point of corresponding two eyes to differ the difference that equals user's two refraction of eye degree, and image can be on the far point of two eyes simultaneously during observation.The set glasses have alleviated the contradiction between set and the adjusting.(10), the refracting prisms of set in the glasses are by the overlapping refracting prisms that weaken aberration or color difference eliminating that constitute that connect airtight of two prisms (substrate is towards opposite) of different materials (refractive index difference) or two above prisms (substrate towards can on the contrary also can be not opposite) together.(11), in above-mentioned " (1) set glasses ", increase the non-spherical lens lens (convex lens or concavees lens) of two distortion that disappear.
The purposes that the set glasses of " set lens " are arranged: be the set that improves eyes comfortable indefatigability when making eyes see thing.Comprising: the set glasses that do not comprise presbyopia glasses or spectacles in (1) glasses are to regulate the set glasses of the consolidation function of glasses as improving spectacles or presbyopia glasses or spectacles for long sight etc.(2) presbyopia glasses that use as the custom person's bore hole of often wearing spectacles or closely use glasses.(3) the set glasses that include presbyopia glasses or spectacles in the glasses are comfort type presbyopia glasses that comfort type spectacles or adult use.In addition, comfort type presbyopia glasses can also be used as the teenager closely use glasses for preventing and treating the comfort type that myopia uses in study.
Prepare a kind of " set lens " that above-mentioned set glasses are used, be the burr lens or be shaped can directly be installed to lens on the spectacle frame, former and later two surfaces that are characterised in that lens are two identical planes of refraction that clip certain angle, comprise: former and later two surfaces of lens are to clip refracting prisms (Figure 17 that certain angle constitutes by two plane of refraction, Figure 18), or former and later two surfaces of lens are by two identical on-plane surfaces (sphere for example, the disappear aspheric surface of anamorphic lens, the face of cylinder etc.) plane of refraction clips refracting prisms (Figure 19 that certain angle constitutes, Figure 20); Comprise that also lens is the refracting prisms of being made by a kind of material (Figure 17, Figure 19), or lens is to be connected airtight the color difference eliminating that together constitutes or weakened the refracting prisms (Figure 18, Figure 20) of aberration by two prisms of different materials (refractive index difference) (two prism substrate of unlike material towards overlapping connecting airtight together) on the contrary or two above prisms.
" set lens ", " set glasses ", " purposes of set glasses " are the multinomial inventions that belongs to a total inventive concept." set lens " is a kind of lens that improves set that preparation set glasses use.Beneficial effect:
It is different with the purpose and the Expected Results of prior art " the ZL95201944.2 eyesight returns mirror " that the present invention gathers glasses.The purpose difference: the purpose that eyesight returns mirror is to temper eye therapy myopia; The purpose of set glasses mainly is to allow eyes feel comfortable, can see the thing indefatigability for a long time, the protection eyes.The Expected Results difference: it is the ability of restraining oneself of tempering eyes with the gap that widens set and regulate that eyesight returns the mirror Expected Results, and the collocation that makes binocular integration and adjusting is away from custom, so eyes are uncomfortable, fatiguability; Set glasses effect is to dwindle binocular integration and the gap of regulating collocation, makes collocation near custom, endures hardships so eyes are comfortable.Structure difference: the substrate of two prisms of set glasses towards with the angle of deviation size all be left-right symmetric.Purposes difference: eyesight returns mirror and is used for the treatment of myopia or long sight, promptly is used for the teenager and is not used in the elderly; The set glasses are used to improve the presbyopia glasses of prior art and the set shortcoming or the set glasses of spectacles are presbyopia glasses of myopia bore hole use or see and closely use glasses.The presbyopia that custom is worn spectacles sometimes when wearing spectacles and see near thing because image does not too closely see Chu, eyes fatigue easily again when extracing spectacles and seeing near thing with bore hole.Inwardly (the set glasses of) prism can be used as custom and wear the glasses that use when the myopia of spectacles is watched nearly thing or inwardly down to have common spectacles frame and symmetrical two substrates." comprise the set glasses of regulating lens (being convex lens lens or concavees lens lens) " among the present invention following beneficial effect is arranged: (1) changes set with set lens (both refracting prisms), change adjusting with regulating lens, prism spectacles and existing spectacles or presbyopia glasses are combined, overcome or alleviated the shortcoming of spectacles or presbyopia glasses, be that comfort type spectacles or comfort type presbyopia glasses (illustrate: no longer become myopia because of becoming oneself typing of eye, so do not need pre-myopia prevention for the adult, it is the presbyopia glasses).(2) the set glasses use it not need the laundering period as being also advantageous in that of comfort type spectacles or comfort type presbyopia glasses, and usefulness can arbitrarily be extractd or wear to glasses at any time when watching, and can not feel to feel bad.Myopia watches to wear when far away and uses the comfort type spectacles, sees and uses bore hole when near.(3) though prism cooperates with lens can make set and regulate interlock, prism and the lens eyes of arranging in pairs or groups when inaccurate are seen thing still incomplete same with the custom of seeing thing with bore hole (as Figure 12, Figure 13, Figure 14, shown in Figure 15) by glasses.When two focuses overlap about the set glasses (as Fig. 9 or Figure 10 or shown in Figure 11), the degree that prism changes set sizes changes the degree of regulating size with lens and equates, eyes see that by glasses the virtual image of object just sees real-world object the same (as Fig. 5, Fig. 6, shown in Figure 3) with bore hole.(4) sensation that the set glasses beneficial effect that two focuses overlap about not only is to see thing by the set glasses and bore hole are seen feeling identical but also being the influence that (in usual range) is not subjected to object distance or image distance of thing.No matter see at a distance or see nearby, always the set of eyes with regulate cooperate the same with custom, the maintenance synchronous interaction.This because: when two focuses overlapped about the set glasses, the matching relationship of prism and lens was N=(F-X) sin B in the set glasses.B, B1, B2 are the horizontal components of refracting prisms angle of deviation in the formula, 2N is the distance between the optical centre of two lens, F is the focal length of lens, X be lens and prism pitch (prism preceding near observe the thing lens in the back during near eyes X for just, prism rear lens when preceding X for bearing.Though the X influence is very little, should reduce X during the design glasses) as far as possible.Suppose that the observation thing is U to the distance of lens, the set glasses are if be made of convex lens and prism, then when image during in the infinite distance, B1=arcsin[N/ (F-X)], as image B2=arccos{N/[FU/ (F-U)-X when arbitrarily far away] }-arccos [N/ (U-X)], get U=20 centimetre respectively, U=50 centimetre, U=1 rice (and get N, F, X numerical value commonly used) or the like numerical value substitution formula, B1 approximates B2 by calculating as can be known.The set glasses are if be made of concavees lens and prism, then when observe thing to concavees lens apart from the infinite distance time, B1=arcsin[N/ (F-X)], when observing thing to any B2=arccos[N/ (U-X) far the time of the distance of concavees lens]-arccos{N/[FU/ (F+U)-X]).Get U=50 centimetre respectively, U=1 rice, numerical value such as U=100 rice (and get N, F, X numerical value commonly used) are the substitution formula respectively, and B1 approximates B2 by calculating as can be known.All " B1 equals B2 " this exponent is little of ignoring apart from the influence of U under the various situations in usual range.No matter so in usual range the object distance, no matter also image distance, the binocular integration when watching the object virtual image and the relation of adjusting by the set glasses just and bore hole the same when seeing real-world object, the set of eyes and adjusting are synchronous interactions.When (5) seeing near thing with the set glasses, image can be placed on the eyes far point by the set glasses, eyes equally loosen with regard to seemingly seeing distant objects, reach the effect of protection eyes.So the set glasses are that old man, adult, teenager etc. see the comfortable glasses that nearly thing is used.For example emmetropia is worn the comfort type presbyopia glasses indefatigability of reading a book for a long time; The teenager uses comfort type presbyopia glasses study can effectively prevent myopia because of seeing that for a long time nearly thing causes.Then can be in set and the synchronous interaction of regulating when (6) myopia is placed on than bathomorphic far point image slightly at a distance by the set glasses temper eyes and in long-term the use, far treating myopia by seeing for a long time by the stretching eye's lens.Gather with the adjusting harmony in the use, meet custom.(7) effect of set glasses is not subjected to the influence of two spacings of observer (interpupillary distance) size, interpupillary distance big a bit or a little bit smaller different observers all can use same set glasses, because the change of observer's interpupillary distance causes the prismatic effect of convex lens or concavees lens generation and the set variation that observer's interpupillary distance changes the prismatic lens that causes and offsets, so increased the versatility of glasses, helped reducing specification, produce in batches and saved cost.(8) degree that the degree of prism change set sizes and lens change the adjusting size when two focuses do not overlap about the set glasses is unequal, two focuses from must adjusting far away more and the contradiction of set big more, two focuses from must near more adjusting and the gap of set more little, gap is pigsney comfortable more indefatigability more just more.Two focuses do not overlap but less at interval also have to alleviate not accommodate slow down tired effect.The aberration of lens is bigger when two focuses overlap, and keeps two focus appropriate intervals and can weaken aberration.Selecting two focus spacings can take into account " aberration " and " regulate with set contradiction " less than 3 centimetres makes the both suitably less.(9) when user's left vision and right vision not simultaneously, in other words when left eye far point and right eye far point gap are big, " the glasses purpose of prior art is that image is on the far point of two eyes simultaneously; two eyes are treated respectively as two bodies; so the diopter of the left lens of glasses and right lens is unequal; for example spectacles usually are left and right sides eyeglass differences, and result's distance that to be left eye is seen in glasses the object virtual image arrive right eye to the distance of left eye and the object virtual image that right eye is seen is different ".The feature that the present invention gathers glasses " no matter the far point of eyes is identical or gap is bigger; the diopter of two lens all equates about corresponding eyes " is that two eyes are regarded as an integral body, and it is constant that purpose is to keep eyes to regulate with the custom of set collocation as far as possible.When gathering glasses and watch with the present invention, if the far point of eyes is identical, image can drop on the far point of eyes simultaneously; If the far point gap of eyes is bigger, then image can drop on the far point of relatively poor eyes and in the far point of the better eyes of another; Most cases can be image in the far point of two eyes, image is identical with distance to right eye to the distance of left eye.Such beneficial effect real-world object that to be the object virtual image seen in the glasses in set see with bore hole is the same, and about the diopter of two lens equate that the feature that does not change with glasses wearer's two eye vision differences helps producing in batches and reducing cost.(10) refracting prisms glasses and a left and right sides eyeglass diopter differ the presbyopia glasses combination that equals user's two refraction of eye degree differences, image can be on the far point of two eyes simultaneously when near viewing, adjusting is loosened fully, and refracting prisms glasses (set glasses) can partly alleviate the contradiction between set and the adjusting.(11) a kind of special circumstances are the people that wear the diopter difference of two eyeglasses " about " glasses custom at having formed usually, this people's bore hole sees that thing can feel to feel bad, because the eyes set is changed with the custom of regulating, bore hole sees that thing does not meet custom on the contrary, so " two set glasses that lens strength equates " and " glasses that custom is worn " overlap and just meet custom, this moment can because the glasses worn of custom about the diopter difference of two lens the set glasses are shown as in form about the diopter difference of two lens, but essence the same with " diopter of two lens is equal " all be to make " adjusting of eyes and set meet custom ".For example " myopia is watched the prior art spectacles of usefulness far away " and " facing the set glasses of watching nearly usefulness " overlapping composition " bathomorphic see nearly dedicated collection glasses " (seeing supplementary features 8).(12) one deck is that another layer of prism spectacles is the two-layer set glasses of lens, is beneficial to overpay using instead and arranging in pairs or groups with need between the glasses, can also promptly can work as the use of set glasses again when the prior art glasses use.The set glasses that for example add prism spectacles on the presbyopia glasses only see that with the presbyopia glasses thing is beneficial to the distance of accurate judgment object distance, add that with the presbyopia glasses prism spectacles sees the then comfortable indefatigability of thing.(13) image of seeing in the set glasses that the spherical lens lens cooperates with prism has point deformation, for example convex surface or concave surface is regarded as in the plane.The set glasses that the non-spherical lens lens cooperates with prism can overcome this shortcoming.(14) at the bottom of can rotating prism towards spectacle frame, maybe can change the spectacle frame of two optical center of lens distances, maybe can change the spectacle frame of distance between refracting prisms and the lens, these adjustable mirror holders can be adjusted cooperating between prism and the lens, make the set of glasses and adjusting reach optimum efficiency.(15) heterochromatic light is by the angle of deviation difference of prism, the degree that prism changes set sizes is also different, achromatic prism can make heterochromatic light identical or close by the set behind the prism, the close accurate collocation that helps between prism, lens and the spacing of heterochromatic radiation direction promptly is beneficial to and makes " degree that prism changes set sizes equates with the degree that lens change the adjusting size ".And make image clear.(16) set glasses left and right sides eyeglass symmetry, equate and irrelevant with interpupillary distance, not limited by individual characteies such as user's interpupillary distance, far point, help producing in batches, save cost, conveniently sell and buy.(17) refracting prisms preceding near observe thing, lens in the back near eyes, advantage is to change the light general orientation earlier to change the poly-of light again and loose, and can reduce aberration and make better effects if.(18) the present invention " set lens " the relatively difference of other lens is with beneficial effect: former and later two surface curvatures of general lens are different (as myopia eyeglass or presbyopia eyeglass, only change and regulate, do not change set), perhaps the surface that former and later two curvature are identical is that opposing parallel is (as the sunglasses lens, do not change adjusting and do not change set yet), the difference of lens of the present invention is former and later two air spots of lens capable identical with curvature (can change set, change hardly and regulate).(19) it is clear that achromatic prism can make colored image.(20) " the two-layer lens that prism separates with lens " helps adjusting the angle of incident ray than " the compound spectacles sheet that prism and lens are combined into one ", reduces oblique astigmatism, can make imaging effect better.(seeing Figure 16).(21) on-plane surface " set lens " can also connect airtight with the eyeglass (presbyopia eyeglass or myopia eyeglass) on other glasses (paste or overlay or picture frame fixing etc.) constitute the compound spectacles sheet together.
