The purpose of spectacles of the present invention is set that the adjusting that can improve eyes can improve eyes again, improves the eyes observing effect and feels comfortable indefatigability by eyes.
The technical scheme of first invention is: a kind of spectacles; Lens and spectacle frame (spectacle frame is the support of crutch glasses sheet) are arranged; It is characterized in that facing to nearly the use interpupillary distance of the distance between the optical centre of the optical centre of the lens of left eye and the lens that faces toward right eye less than the user; Comprise that these two optical centres overlap; All be that (can be the compound spectacles sheet that separates facing to the lens of left eye and the lens that faces toward right eye wherein, also can be the compound spectacles sheet that fuses to the compound spectacles sheet that is combined into of myopia eyeglass and the prism of a substrate in the outside of prior art facing to the lens of left eye with facing to the lens of right eye.The lens of prior art is meant the eyeglass of the photocentre of negative lens facing to pupil).
Additional technical feature of the present invention is following: (1), spectacles are two compound spectacles sheets of " non-one " facing to the lens of left eye with facing to the lens of right eye, about two compound spectacles sheets featheredge all at inboard, webbing all in the outside.(2); Spectacles are symmetrical two lenses facing to the compound spectacles sheet of left eye with facing to the compound spectacles sheet of right eye; The diopter of these two compound spectacles sheets is identical (no matter the far point of eyes is identical or gap is bigger; The diopter of two eyeglasses all equates), the angle of deviation size of two compound spectacles sheet geometric centers identical (at the bottom of the prism in compound towards also left-right symmetric), the distance between the optical centre of two compound spectacles sheets is less than 3 centimetres; Directional light (for example sunshine) simultaneously between two virtual focuses forming of the left eyeglass lens through glasses and right eye eyeglass distance less than 3 centimetres (Fig. 6).Distance between two virtual focuses of this of spectacles=2N-2sinB ÷ D; Wherein 2N is two distances (rice) between the complex optics concave optical center of lens; D is the diopter (D=1/ rice) of concavees lens in the complex optics, and B is the angle (unit is an angle) of prism angle of deviation in the compound spectacles sheet.(3); Perhaps; Directional light overlaps through the left eyeglass lens of glasses and two virtual focuses of right eye eyeglass formation simultaneously, and the relation between left eyeglass lens and the right eye eyeglass is sinB=ND, and wherein 2N is the distance between left eyeglass lens geometric center and the right eye eyeglass geometric center; D is the diopter of lens, and B is the angle of deviation (Fig. 5) of lens on the geometric center line direction of geometric center.(4), perhaps, spectacle frame is to adjust the spectacle frame that changes distance between left eyeglass lens and the right eye eyeglass.Promptly can change distance between two virtual focuses about spectacles through changing 2N.(5), perhaps, two compound spectacles sheets about the lens one of the corresponding eyes of spectacles.(6), perhaps, the left eyeglass lens of spectacles and right eye eyeglass are that the lens and the optical centre that fuse overlap.(7), perhaps, lens is ability color difference eliminating or the compound spectacles sheet that weakens aberration, and the compound spectacles sheet is the overlapping compound spectacles sheet of being processed by different materials that together constitutes that connects airtight of eyeglass.(8), perhaps, the compound spectacles sheet is slim compound spectacles sheet; One side of slim compound spectacles sheet is thicker and another side is thinner than the myopia eyeglass of prior art than the myopia eyeglass of prior art, and whole compound spectacles sheet is added with a prism than on the myopia eyeglass of prior art compound spectacles sheet is thin.
A kind of spectacles; Lens and spectacle frame are arranged; Lens is two light microscopics or multifocal lens (multifocal lens comprises the progressive multifocal eyeglass); It is characterized in that lens is the lens of prior art and the compound spectacles sheet of the compound formation of local prism, (lens of prior art is meant two light microscopics or multifocal lens or progressive multifocal eyeglass here.The eyeglass of two light spectacles of prior art mainly is made up of two local negative lenses or mainly is made up of a local negative lens and a local positive lens; The eyeglass of many focuses spectacles of prior art mainly is to be become with local positive lens groups by local negative lens more than two or local negative lens; And the photocentre of local lens is facing to pupil on the spectacles of two light microscopics of prior art or multifocal lens, equals interpupillary distance facing to the distance between the photocentre of the photocentre of the local negative lens of left eye and the local negative lens that faces toward right eye.), left eyeglass lens and right eye eyeglass left-right symmetric, the main photocentre of compound spectacles sheet less than 1.5 centimetres, also comprises wherein that main photocentre is on symmetrical center line to the distance of two eyeglass left-right symmetric center lines; Show as the left eyeglass lens of directional light through glasses and can form the different focus of two or more focal lengths (virtual focus or real focus); Directional light also can form the different focus of two or more focal lengths (virtual focus or real focus) through the right eye eyeglass of glasses simultaneously; About distance between identical two focuses of the main focal length of two lenses less than 3 centimetres or overlap; Other secondary focal point also can be in this scope, and focus can be that virtual focus also can be a real focus.
Beneficial effect
Spectacles of the present invention and prior art spectacles compare, the difference of (1) purpose: the prior art purpose is to change adjusting to see the observation thing clearly, the present invention seeks to improve set simultaneously in the change adjusting and makes adjusting and integrated interlinked.(2) Expected Results difference: prior art only changes adjusting and does not change set, and the collocation that makes binocular integration and adjusting is away from custom, so eyes are uncomfortable, fatiguability, needs one period laundering period that changes custom, plucks when wearing when being difficult for; The present invention changes adjusting and set simultaneously, can alleviate set and adjusting contradiction or make collocation near being accustomed to, and endures hardships so eyes are comfortable.Myopia watches to wear when far away and uses spectacles of the present invention, sees when near and also can comfortablely endure hardships with bore hole, do not need the laundering period, can the time pluck when wearing.(3) structure difference: prior art requires " optical centre of eyeglass being placed on the dead ahead of pupil; guarantee that sight line was through the optical centre of eyeglass when the glasses wearer saw object; avoid producing prismatic effect ", and the distance between the optical centre of the optical centre of the left eyeglass lens of prior art glasses and right eye eyeglass equals user's interpupillary distance; Distance between the optical centre of the optical centre of the left eyeglass lens of spectacles of the present invention and right eye eyeglass is less than user's the nearly interpupillary distance of using; Spectacles of the present invention must produce and utilize prismatic effect, the optical centre of left and right sides eyeglass all the inboard of pupil in addition about two photocentres overlap or lens on do not have photocentre.Cooperating between the consolidation function that can improve spectacles like this and the regulatory function.
Also have following beneficial effect among the present invention: (1) " distance about spectacles between the optical centre of two lenses is less than nearly interpupillary distance of using of user " have alleviate uncomfortable with slow down tired effect; When about the distance that departs from of optical centre and geometric center on two lenses about about 3 centimetres of its two virtual focus spacings when equaling 1.5 centimetres, if the optical center distance on two lenses is nearer then spacings two virtual focuses are also more little.Two virtual focuses leave far away regulate with the contradiction of set big more, two focuses leave nearer regulate with the gap of set more little, gap more pigsney with regard to comfortable more indefatigability more.(2) the compound spectacles sheet aberration of homogenous material is bigger when two virtual focuses of two lenses about spectacles overlap, and keeps two focus appropriate intervals and can weaken aberration.So photocentre on the selection lens and geometric center spacing are less than 1.5 centimetres or two virtual focus spacings can take into account " aberration " less than 3 centimetres and " regulating the contradiction with set " makes the both suitably less.(3) 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; treat two eyes respectively as two bodies; so the diopter of the left lens of glasses and right lens is unequal, and the spectacles of prior art usually are that left and right sides eyeglass is different, 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 present invention sees two eyes and is integral that purpose is to keep the custom that eyes are regulated and set is arranged in pairs or groups constant as far as possible, so no matter the far point of eyes is identical or gap is bigger, the diopter of two compound spectacles sheets all equates about corresponding eyes ".When watching with spectacles of 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 in glasses, seen see with bore hole is the same, and about the diopter of two compound spectacles sheets equate that the characteristic that does not change with glasses wearer's two eye vision differences is beneficial to and produce in batches and reduce cost.(4) the set effect of spectacles of the present invention does not receive the influence of observer's two eye pupils apart from size; Change concavees lens produce in the compound spectacles sheet cause prismatic effect because of observer's interpupillary distance and change prism produces in the compound spectacles sheet that causes set because of observer's interpupillary distance and change and offset; So interpupillary distance is a bit big or a little bit smaller different observers all can be used same glasses; These characteristics have increased the versatility of glasses; Help reducing specification, produce in batches and practice thrift cost, convenient dealing.(5) two of spectacles of the present invention compound spectacles sheet left-right symmetric; Be that diopter equates, compound prism substrate towards opposite, whole angle of deviation equal and opposite in direction and with the irrelevant characteristic of interpupillary distance; Reduced the restriction of individual characteies such as user's interpupillary distance, far point; Help producing in batches, practice thrift cost, the convenient sale and purchase.(6) though prism cooperates with concavees lens can make set and regulate interlock, prism and the concavees 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 (like Fig. 7, Fig. 8, Fig. 9, shown in Figure 10) through glasses.When two virtual focuses about glasses overlap (as shown in Figure 5), the degree that prism changes set sizes changes the degree of regulating size with concavees lens and equates, eyes see that through glasses the virtual image of object just sees real-world object the same (as shown in Figure 2) with bore hole.(7) beneficial effect that two virtual focuses overlap about spectacles of the present invention not only is to see that through glasses the sensation of thing sees that with bore hole identical but also (in usual range) this sensation of feeling of thing does not receive the influence of object distance or image distance.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.Because: when two virtual focuses overlapped about spectacles of the present invention, the matching relationship of prism and concavees lens was N=F * sinB in the compound spectacles sheet.If B, B1, B2 are the horizontal components of prism angle of deviation in the compound spectacles sheet; 2N is the distance between the optical centre of two concavees lens in the compound spectacles sheet; F is the focal length of concavees lens, diopter, the F=1 ÷ D that D is concavees lens, and establishing and observing thing is U to any distance of compound spectacles sheet.When observe thing to the compound spectacles sheet apart from the infinite distance time, B1=arcsin (ND) is when observing thing to any B2=arccos (the N/U)-arcos{N/ [FU/ (F+U)] far the time of the distance of compound spectacles sheet }.Get U=50 centimetre respectively, U=1 rice, U=100 rice numerical value such as (also getting the numerical value commonly used of N, F, X simultaneously) is the substitution formula respectively, can know that through calculating B1 approximates B2.All be that " B1 equals B2 " this exponent is little of ignoring apart from the influence of U under the various situation in usual range.So no matter object is far and near in usual range, no matter also image is far and near, the same when the binocular integration when watching the object virtual image through spectacles of the present invention is just seen real-world object with bore hole with the relation of adjusting, the set of eyes and adjusting are synchronous interactions.(8) can change the spectacle frame of left and right sides compound spectacles sheet spacing, promptly change two compound spectacles sheet concave optical center of lens spacings or change the spacing of two virtual focuses.Can adjust the matching relationship of the set and the adjusting of glasses, reach optimum efficiency.(9) thus because of two eyes to watching compound spectacles sheet front surface integral body to slope inwardly nearby, help reducing oblique astigmatism, can make imaging effect better.(10) image of in the compound spectacles sheet of sphere concavees lens and prism, seeing has point deformation, and the compound spectacles sheet of aspheric surface concavees lens and prism can overcome this shortcoming.(11) material of manufacturing eyeglass has different refractive indexes for the visible light of different wave length, and prismatic effect can produce aberration makes colored image unclear.The prismatic effect of different wave length light is different in the colored image; The degree of set sizes is also different; The compound spectacles sheet of can color difference eliminating or weakening aberration can make the light of different wave length identical or close through the set behind the prism, helps making " degree that prism changes set sizes and concavees lens change regulate big or small degree equate " and makes colored image clear.(12) slim compound spectacles sheet light transmission in light weight is good.
With the spectacles that are lens of compound more a plurality of different prisms on bifocus or multifocal lens or the gradual change focus lens; With prior art be that the glasses of lens are compared with bifocus or multifocal lens or gradual change focus lens; Advantage is to have reduced set and the contradiction of regulating, and eyes are comfortable endures hardships.

Embodiment
A kind of spectacles that are configured to by lens and crutch glasses sheet; The difference of this glasses and prior art spectacles is facing to nearly the use interpupillary distance of the distance between the optical centre of the optical centre of the lens of left eye and the lens that faces toward right eye less than the user; Lens is the myopia eyeglass of prior art and the compound spectacles sheet that the prism of a substrate in the outside is combined into, and the compound spectacles sheet can be one of following example (section of compound spectacles sheet such as Figure 12, Figure 13, Figure 14, Figure 16, shown in Figure 17):
The example 1 of lens: Figure 12 is a kind of synoptic diagram of compound spectacles sheet, and Figure 11 is the synoptic diagram that helps to understand Figure 12.Shown in Figure 11 is that parallel rays 5 is through separately the prism 1 and prior art myopia eyeglass 2 backs of two bodies seem that the size of the angle of deviation 3 of prism is B all from the virtual focus 4 of prior art myopia eyeglass.Figure 12 is that prism and prior art myopia eyeglass connect airtight the compound spectacles sheet synoptic diagram that (compound) constitute together (wherein prism and concavees lens can be the eyeglasses of commaterial; Two eyeglasses that also can not be commaterial connect airtight compound spectacles sheet together); Parallel rays 5 through the prism in the compound spectacles sheet 61 and prior art myopia eyeglass 2 backs like all from the virtual focus 4 of prior art myopia eyeglass; The big or small B of the angle of deviation 3 of prism equals the angle of deviation of compound spectacles sheet, and the diopter of prior art myopia eyeglass equals the diopter of compound spectacles sheet.
The example 2 of lens: Figure 13 is the synoptic diagram of the compound spectacles sheet 6 of one, and prism that comprises in the compound spectacles sheet and prior art myopia eyeglass are commaterials and are one.
The example 3 of lens: Figure 14 is the synoptic diagram of thin formula compound spectacles sheet 6; 7 is surfaces that prism adds the compound spectacles sheet of prior art myopia eyeglass among the figure; The 8th, the surface of prior art myopia eyeglass; The 9th, the surface of thin formula compound spectacles sheet, thin formula compound spectacles sheet is equivalent on prism adds the one compound spectacles sheet of prior art myopia eyeglass, deduct the mirror body of one deck uniform thickness.
The example 4 of lens: (Figure 15 is the synoptic diagram that helps to understand Figure 16; Figure 16 is a kind of synoptic diagram of compound spectacles sheet) the last figure of Figure 15 be by a prism 11 and another substrate towards opposite prism 10 (another kind of material) but connect airtight the color difference eliminating that together constitutes or can slacken the achromatic prism 12 (12 constitute by two kinds of material different) of aberration, figure below is the synoptic diagram of prior art myopia eyeglass 2.Figure 16 is that achromatic prism 12 adds achromatism compound spectacles sheet 13 synoptic diagram (the compound spectacles sheet can be to be made up of two kinds of materials or three kinds of materials) that prior art myopia eyeglass 2 constitutes, it be two refracting prisms substrates of processing by two kinds of materials of different refractivity towards opposite overlapping connect airtight the prism that constitutes color difference eliminating or weaken aberration after again with an overlapping compound spectacles sheet that connects airtight together of myopia eyeglass.
The example 5 of lens: Figure 17 is that thin formula achromatism compound spectacles sheet 15,15 is connected airtight together by prism 10 and complex optics 14 and constitutes (the two-layer of compound spectacles sheet is to be made up of two kinds of material different, and the webbing of two-layer eyeglass is towards opposite)." connect airtight " and comprise that stickup, hot pressing, screw connect, one or the like method is fixed, is moulded to picture frame.Complex optics 14 is equivalent to prism 11 among Figure 16 and adds the mirror body that deducts one deck uniform thickness behind the concavees lens 2 again, and prism 10 is equivalent to the prism 10 among Figure 16.
The example 6 of lens: the compound spectacles sheet is combined into the lens that a lens constitutes color difference eliminating or weakens aberration after overlapping connecting airtight with another refracting prisms of processing with the different refractivity material again by the prism of same material and concavees lens.If this compound spectacles sheet is eliminated behind the mirror body of one deck commaterial of equal thickness then is become slim lens (Figure 17).
Explanation about the compound spectacles sheet: prior art myopia eyeglass can be the aspheric surface concavees lens lens of the sphere concavees lens lens or the distortion that disappears; The surface of prism can identical with the front surface of prior art myopia eyeglass (prism be preceding), also can identical with the back surface of prior art myopia eyeglass (prism is in the back).It is that the compound spectacles sheet is: the compound spectacles sheet (Figure 16) of the aspheric surface prismatic lens+aspheric surface concavees lens lens of the distortion that the disappears=distortion that disappears; Perhaps, sphere prismatic lens+sphere concavees lens lens=compound spectacles sheet (Figure 12), perhaps; Achromatic prism+concavees lens=achromatism compound spectacles sheet (Figure 16); Perhaps, the concavees lens of the prism of A material+B material and the composite mirrors of prism=achromatism compound spectacles sheet (Figure 17), achromatism refers to color difference eliminating or weakens aberration.The compound spectacles sheet can also be platycelous eyeglass or double concave type eyeglass.The compound spectacles sheet can have astigmatism and astigmatism is arranged because of the myopia eyeglass of prior art.On the compound spectacles sheet plated film can be arranged, also can be optical filtering.Prism angle of deviation size is given an example as table with the collocation of the dioptric size of concavees lens (the myopia eyeglass of prior art) in the compound spectacles sheet; After the unit prism degree of angle of deviation size is meant that prism makes light generation deviation; On incident ray apart from 1 meter of prism, the cms of refracted ray deviation on the vertical direction of incident ray.Angle is meant that prism makes the angle of light generation deviation, when 45 angles, is 100 prism degrees.
The embodiment of glasses is all right as follows:
Glasses example 1: the distance about the spectacles of spectacles and prior art are distinguished and are between the optical centre of two lenses is closely used interpupillary distance less than the user's.A kind of spectacles shown in Figure 180 have respectively been pasted a prism 1 that substrate is outside on the front surface of two lenses 16 about the prior art spectacles, promptly the lens of corresponding eyes is to be equivalent to combine the compound spectacles sheet that constitutes with the concace mirror lens 16 of prior art spectacles by the outside prism 1 of substrate.Wherein two of the prior art spectacles lenses all are the sphere lenses, about the diopter different (also can be identical) of two compound spectacles sheets.The back surface of compound spectacles sheet is identical with the prior art spectacles, and the 26th, the inboard on surface behind the compound spectacles sheet, the 27th, the outside on surface behind the compound spectacles sheet; And the outside 25 of front surface is more forward than inboard 24.The nose holder 17 of spectacles, mirror leg 18 or the like parts are identical with the prior art spectacles.
Glasses example 2: the spectacles shown in Figure 25 (front schematic view) and Figure 26 (top cross-sectional view) and the difference of prior art spectacles are that lens is the myopia eyeglass of prior art and the compound spectacles sheet 6 of a prism; And about the optical centre of two compound spectacles sheets coincide with on the coupling shaft 28 of the bridge of the nose; A rotatable coupling shaft 28 is arranged on the bridge of the nose of spectacle frame, pivot can change between left eyeglass lens and the right eye eyeglass distance with change prism substrate in the compound spectacles sheet towards.In the spectacles compound spectacles sheet prism substrate towards also can be all along with rotation outwards on the lower side or all outwards on the upper side.Mirror leg 29 also can rotate, and width different shape of face persons can use.
Glasses example 3: shown in Figure 20 (front view), Figure 21 (top cross-sectional view), spectacles and the difference of prior art spectacles are that the left eyeglass lens and the right eye eyeglass of corresponding eyes is (concavees lens) the compound spectacles sheets 22 with same optical centre 21.The left eyeglass lens of the corresponding eyes of spectacles and the right eye eyeglass fuses and with picture frame be the glasses of global formation.The geometric center 23 of the lens of corresponding left eye of spectacles or right eye and the distance of optical centre 21 are greater than 1.5 centimetres (optical centre and geometric center all are meant the position when it is seen in the front), spectacles left-right symmetric.
Glasses example 4: the left eyeglass lens of the spectacles shown in Figure 20 (front view), Figure 22 (top cross-sectional view) and right eye eyeglass are an ability color difference eliminating that fuses or (concavees lens) the compound spectacles sheet 22 that weakens aberration.The geometric center 23 of the lens of corresponding left eye of spectacles or right eye and the distance of optical centre 21 are greater than 1.5 centimetres.
Glasses example 5: spectacles shown in figure 19, two lenses 9 that are characterised in that spectacles are that effect is equivalent to the compound compound spectacles sheet of a prism on the myopia eyeglass of prior art.Lens 9 is slim compound spectacles sheets; Webbing is outside, left-right symmetric, promptly about the diopter of two compound spectacles sheets identical; About the angle of deviation size of two compound spectacles sheets identical; Two virtual focus spacings that two eyeglasses of directional light through glasses form are less than 3 centimetres, distance=2N-2sinB/D between two virtual focuses of this of spectacles, and wherein 2N is two distances between the complex optics concave optical center of lens; D is the diopter of concavees lens in the complex optics, and B is the deflection angle of prism in the complex optics.(perhaps, get 2N and equal two distances between the complex optics geometric center, get (level) deflection angle that B equals the complex optics geometric center, D is that the diopter of compound spectacles sheet is the inverse of focal length).The bridge of the nose 19 of spectacle frame is scalable, and the 20th, the part screw of control bridge of the nose telescopic level, the adjustment bridge of the nose can change the distance between left eyeglass lens and the right eye eyeglass, promptly changes the distance between left eyeglass lens virtual focus and the right eye eyeglass virtual focus.Compound spectacles sheet 9 is slim lenses of aspheric surface.Promptly be equivalent to the aspheric surface myopia eyeglass of prior art and the compound spectacles sheet of prism.When two virtual focuses of spectacles overlapped, the collocation between the N of spectacles, D, the B was for example like table.
Glasses example 6: spectacles are shown in figure 23, and two lenses of spectacles are slim compound spectacles sheets 15 that the compound ability color difference eliminating of prism and concavees lens maybe can weaken aberration.The temporo side 25 of compound spectacles sheet front surface is more forward than nasal side 24, and promptly front surface integral body slopes inwardly, and the temporo side 27 on back surface is also than surface, nasal side 26 forward i.e. back also integral body slope inwardly (perhaps the surface, back can be the same with the prior art spectacles).Directional light overlaps through the left eyeglass lens of glasses and two virtual focuses of right eye eyeglass formation simultaneously.This moment N=sinB/D; 2N is two distances (unit is a rice) between the compound spectacles sheet concave optical center of lens in the formula; D is the diopter (unit be D, promptly 1/ meter) of concavees lens in the complex optics; The diopter of two compound spectacles sheets is identical, and B is the angle of deviation (unit is an angle) of prism in the complex optics, and the substrate of prism is all outside.(perhaps, get 2N and equal two distances between the complex optics geometric center, get the deflection angle that B equals the complex optics geometric center, D is that the diopter of compound spectacles sheet is the inverse of focal length).Concrete collocation between spectacles N, D, the B is for example like table.(the desirable 2N of spectacles equals user's interpupillary distance)
Glasses example 7: spectacles shown in Figure 24 and spectacles shown in Figure 23 difference are: two achromatism compound spectacles sheets 13 of spectacles are to connect airtight achromatic prism 12 to constitute on the back surface of prior art myopia eyeglass 2.
Glasses example 8: spectacles are far and near dual-purpose type glasses; Two lenses of spectacles are symmetrical two two light microscopics; Different with two light microscopics of prior art is on each two light microscopic lens and corresponding compound two prisms of two concavees lens (or convex lens of concavees lens), and two photocentres of left eyeglass lens and two photocentres of right eye eyeglass are all outside lens and overlap.Each two light microscopic lens all has two focuses (two light microscopics has two virtual focuses if two light microscopic is made up of two concavees lens during solar light irradiation; If two light microscopics are made up of concavees lens and convex lens then two light microscopic has a virtual focus and a real focus); Directional light can form four focuses through symmetrical two the two light microscopics of glasses; Two over focuses overlap wherein, about two perifocus overlap.The glasses matching relationship also is N=sinB/D, when D be negative value when promptly being concavees lens prism substrate all outside, when D is that prism substrate is all inside when promptly being convex lens, get 2N and approximate interpupillary distance greatly.
Glasses example 9: two lenses of spectacles are symmetrical multifocal lens or progressive multifocal eyeglass; Similar with the multifocal lens or the progressive multifocal lens glasses of prior art; Their difference is compound a plurality of prisms on the lens; Matching relationship on the lens between compound prism and the corresponding diopter is that D * N approximates sinB greatly, and 2N approximates interpupillary distance, and the compound angle of deviation of diopter D that the everywhere on lens is located in view of the above is the prism of B; When directional light is passed through between the corresponding focus of a left side eyeglass and right eyeglass apart from less than 3 centimetres, perhaps the photocentre on the lens is all in 1.5 centimetres in inner distance eyes center line.
