Summary of the invention
The purpose of the utility model glasses or lens is that poly-the loosing that can improve light can be improved the general direction of light again, the adjusting that promptly can loosen eyes can improve the set of eyes again, overcome the deficiencies in the prior art, improve observing effect, allow the observer feel comfortable indefatigability.
The technical scheme of first utility model is: a kind of glasses, two lenses and the spectacle frame settled about corresponding eyes are arranged, lens is the compound spectacles sheet of convex lens composite prism, it is characterized in that the compound spectacles sheet is by the compound spectacles sheet (that is to say compound spectacles sheet be by convex lens compound angle of deviation compound spectacles sheet greater than the prism formation of " 1.3 take advantage of the refractive diopter of convex lens " prism degree) of the compound angle of deviation of the convex lens of x diopter (D) greater than the prism formation of 1.3x prism degree (△), two lens left-right symmetric i.e. the diopter of two lenses and prism degree big or small identical, prism substrate towards left-right symmetric, the distance between two focuses that form behind two lenses of directional light by glasses is equal to or less than two focuses of 2.5 centimetres or this and overlaps.Illustrate: the location expression of two focuses is actually location expression to two lenses, and mobile lens can change the position of focus.Spectacle frame can be the cap formula, or hand-held, or pure frame or half framework or the like the various supports of frame on ear, the distance between two compound spectacles sheet geometric centers is greatly between 5 centimetres to 7 centimetres, when the center, the visual field of observer's pupil eyes during over against compound spectacles sheet geometric center.
The technical scheme of second utility model is: a kind of lens, be the preparation burr lens used of glasses or the lens of batch process, it is characterized in that lens is the compound spectacles sheet of convex lens composite prism, be to be that the compound angle of deviation of convex lens of x (unit of diopter x is a D=1/ rice) (that is to say greater than 1.3x prism degree and the compound spectacles sheet that constitutes less than the prism of 5x prism degree by diopter numerical value, lens is greater than " 1.3 take advantage of the refractive diopter of convex lens " prism degree and the compound spectacles sheet that constitutes less than the prism of " 5 take advantage of the refractive diopter of convex lens " prism degree by the compound angle of deviation of convex lens), perhaps the distance that departs from of the geometric center of compound spectacles sheet and optical centre is greater than no optics center on 1.3 centimetres or the complex optics.Convex lens in the compound spectacles sheet and prism can be the eyeglasses (comprising polarisation cardiac prominence lens sheet) with one, perhaps the compound spectacles sheet also can be by convex lens and the overlapping compound spectacles sheet that constitutes that connects airtight of another prism together, perhaps the compound spectacles sheet also can be to constitute achromatism compound spectacles sheet by eccentric convex lens composite prism, perhaps the compound spectacles sheet also can be to constitute achromatism compound spectacles sheet by convex lens THREE-IN-ONE COMPOSITE ACHROMATIC prism, or the like, wherein the surface of prism is identical with a surface of convex lens.Convex lens can be spherical lenses, or non-spherical lens, or the Fresnel type lens etc.The compound spectacles sheet also can be the Fresnel type lens.According to Prentice, s rule " on the spherical lens arbitrarily prismatic effect (the prism degree)/incidence point of any to the diopter (D) of distance (the cm)=lens of photocentre " calculating as can be known " optical centre departs from the compound spectacles sheet that the distance of geometric center equals 1.3 centimetres " be equivalent to " the compound spectacles sheet that the prism that the convex lens that the photocentre that diopter is x is placed in the middle and angle of deviation are the 1.3x prism degrees overlaps ".
The additional technical feature of above utility model glasses or lens is as follows: 1, and two focuses that form behind two lenses of directional light by glasses overlap.2, the mirror holder of glasses is adjustable spectacle frames, adjusts spectacle frame and can change distance between the right and left eyes eyeglass or the distance between two focuses.(adjustable spectacle frame can be various patterns, for example the spectacle frame among the ZL03268640.4 " the adjustable device of glasses mirror beam ").The substrate of prism is all towards interior below in 3, two complex optics, and promptly the focus that forms after by two complex optics of directional light is all below compound spectacles sheet front interior.4, the compound spectacles sheet is planoconvex lens (it is the convex lens on plane that a surface is arranged).5, but lens is the compound spectacles sheet that color difference eliminating maybe can weaken aberration, is to constitute eyeglass overlapping connecting airtight of being made by two or more different refractivity material but this color difference eliminating maybe can weaken the lens of aberration.Can be by convex lens and the overlapping achromatism compound spectacles sheet that constitutes that connects airtight of achromatic prism, achromatic prism wherein be that two prism substrate by the different refractivity material are towards overlapping connecting airtight constitutes on the contrary.Perhaps, achromatism compound spectacles sheet also can be by the compound spectacles sheet of convex lens composite prism and the overlapping eyeglass that constitutes that connects airtight of prism of another kind of material together.6, the compound spectacles sheet is the aspherical eyeglass lens that can disappear and distort, be that the compound spectacles sheet is an aspheric surface convex lens lens that certain prism degree is arranged, perhaps, the compound spectacles sheet also can be an aspheric surface convex lens lens and the overlapping lens that connects airtight formation of another prism.
Beneficial effect:
The utility model glasses and prior art ZL 200620031493.6 " triple prism type presbyopic glasses " compare: the heart degree of moving of the utility model eyeglass is bigger or perhaps the eyeglass angle of deviation is bigger.So the utility model glasses have overcome " triple prism type presbyopic glasses " shortcoming that eccentric degree is not enough, and are more effective than " triple prism type presbyopic glasses ", can allow eyes feel comfortable indefatigability when watching.Existing convex lens lens photocentre is placed in the middle or the very little heart that moves is arranged, and area is limited, can not make bigger glasses of eccentric throw and glasses of the present invention.The utility model lens is specifically designed to the bigger glasses of preparation eccentric throw, has overcome the limited area that existing convex lens lens can not be prepared the shortcoming of the bigger glasses of eccentric throw and can make full use of eyeglass, reduces cutting output, reduces cost and produces in batches.
Claimed numerical range is in order to reach following purpose or effect in the utility model: 1, and eyes are regulated and are accustomed to constant with cooperating of set when watching by glasses.Because when eyes are watched by same convex lens, can see regulating with cooperating of set and be accustomed to constant (Fig. 5) than thing image far away and eyes.If two focuses that form behind two lenses of directional light by glasses overlap (Fig. 2), glasses just are equivalent to convex lens (Fig. 1) so, so the utility model selects two focuses of glasses to overlap just can to make glasses to accomplish to keep eyes to regulate and the set synchronous interaction and the effect (Fig. 6) of regulating and being accustomed to cooperating of gathering remaining unchanged, when watching focal length with interior observation thing by glasses the observer feel nature, comfortable, endure hardships.2, take into account the contradiction of adjusting, set and aberration.The big more then aberration of the prism degree of lens is big more, and the aberration of two more little then eyeglasses of focus spacing of glasses is more little.Two focuses do not overlap and spacing during less than 2.5 centimetres eyes regulate to compare with custom and change with the cooperation of set, but intensity of variation is in the comfort zone of the comparative set of eyes, is in order to reach the purpose or the effect of " making eyes feel comfortable endures hardships and reduce the lens aberration " so the utility model is selected " distance is less than 2.5 centimetres between two focuses of glasses ".The glasses that 3, two focuses do not overlap are fit to custom and wear spectacles the person uses.The glasses (Fig. 4) that two focuses do not overlap are equivalent to watch (Fig. 3) by shared convex lens of eyes again after the observer puts on the spectacles that custom wears, and it is constant that the adjusting of myopia eyes and the collocation of set are accustomed to, and eyes are comfortable endures hardships.By calculating the best diopter and the prism degree of the lens of this glasses as can be known, promptly the eyeglass refractive diopter of the glasses that overlap with focus adds that the glasses refractive diopter that custom is often worn is the lens diopter of this glasses, the glasses of the lens prism degree of this glasses and focus coincidence the same." person's bore hole is used apart from being more suitable for being accustomed to wearing spectacles less than two focuses coincidences of 2.5 centimetres of ratios between two focuses of glasses " thus.4, applicability is strong, can produce in batches, reduces cost, convenient dealing.Because the different people of interpupillary distance watches the influence (Fig. 5) that is not subjected to the interpupillary distance size by same convex lens, so glasses for two focuses coincidences, interpupillary distance big a bit or a little bit smaller people all can use (when interpupillary distance equals two center of lens spacings, pupil is in the middle of eyeglass, and the visual field of eyes is placed in the middle; But when interpupillary distance be not equal to two center of lens apart from the time, pupil departs from the middle of the eyeglass, some changes the visual field of eyes, but the adjusting of eyes with gather cooperate the rule constant).Prior art will be treated two eyes respectively during glasses in preparation, can both see clearly Chu in the hope of every eyes, if two eyes far point difference then corresponding eyeglass can be different, if the identical then corresponding eyeglasses meeting in two eyes far points would be identical.The utility model glasses are regarded two eyes as an integral body, no matter user's binocular vision is identical or gap is bigger, two eyeglasses of the corresponding eyes of glasses are symmetry all, i.e. " big or small identical, the prism substrate of the diopter of two lenses and prism degree towards left-right symmetric ", eyes are regulated constant and improve the general applicability of glasses with the custom of set collocation when this feature purpose is to keep not wearing glasses as far as possible and when putting on one's glasses.So the utility model glasses applicability is strong, can reach the purpose and the effect of " reduce specification and unified specification, produce in batches, reduce cost, at any time dealing ".Glasses for " two focus between distance be equal to or less than 2.5 centimetres ", because the contradiction of regulating and gathering is in the comfort zone of the comparative set of eyes, sense of discomfort is less, the uncomfortable people who wears glasses and be accustomed to wearing the low myopia glasses can both use, and be subjected to the interpupillary distance restriction little, so applicability is strong, also be fit to produce in batches.5, the glasses of prior art have changed the custom that cooperates of adjusting with the set of eyes, the eyes that put on one's glasses when not wearing are regulated with gathering and are cooperated rule different, so put on and changed custom behind the glasses of prior art and feel bad, time has been grown and has formed new custom and just adapted to, changed the custom that has on glasses again but remove glasses, so the glasses of prior art were plucked when wearing when being difficult for.The presbyopia glasses are to see nearly glasses, see and should remove when far away that this contradiction glasses of the present invention just are soluble.The image of seeing by the utility model glasses is with to see real-world object the same, put on one's glasses and when removing glasses the adjusting of eyes cooperates rule constant with set, wear so can arbitrarily pluck, comfortable freedom, feel nature.
The utility model also has following beneficial effect: 1, so not changing set, common spectacles do not have the aberration problem.The aberration problem of the influential observing effect of compound spectacles sheet of convex lens composite prism allows eye fatigue easily, uses " but color difference eliminating maybe can weaken the compound spectacles sheet of aberration " can improve observing effect, allows eyes are comfortable endures hardships.2, " can adjust the spectacle frame of distance between the distance that changes between the right and left eyes eyeglass or two focuses " can freely be adjusted according to sensation or needs, makes observing effect feel best.The substrate of prism is all towards interior below in 3, two complex optics, and promptly the focus that forms after by two complex optics of directional light is all below complex optics front interior (Figure 17).Can alleviate the degree of bowing when the observer leans over a book, make that the observer is more comfortable to endure hardships.4, the planoconvex lens, the plane, helps reducing the oblique astigmatism that causes because of prism and is subjected to the interpupillary distance restriction little to thing to the eye convex surface, helps improving observing effect.5, when observing with the sphere lens, the image bulging deformation, the aspherical eyeglass lens of the distortion that disappears can improve observing effect.6, the elderly's eyes are aging, regulating power, collective ability and changing capability weaken, the utility model glasses can satisfy the elderly's physiology, put on one's glasses and see that eyes were regulated the same with set cooperation rule when thing was seen thing with bore hole, meet custom, so can be used as the comfort type presbyopia glasses that the elderly uses.7, children and teenager grow period, if closely reading study is just near-sighted easily for a long time, putting on the reading of the utility model glasses is equivalent to see at a distance, and the adjusting of the reading that puts on one's glasses eyes when read a book with bore hole is with to gather the cooperation rule the same, feel that comfortable enduring hardships just be ready to wear usefulness, so can be used as the glasses that children and teenager see the pre-myopia prevention that nearly thing uses.8, children and teenager are because of after seeing nearly thing generation myopia for a long time, using glasses of the present invention that image is placed on than bathomorphic far point watches slightly at a distance, the custom that the set of eyes cooperates with adjusting is constant and temper eyes by the stretching eye's lens in synchronous interaction, is far treating myopia by seeing for a long time in long-term the use.So the utility model glasses can be used as the glasses of treatment myopia.The glasses that 9 the utility model glasses use as farsightedness are more comfortable than the spectacles for long sight of two convex lens formations of usefulness of prior art.10, the utility model glasses as binocular magnifier use binocular magnifier than convex lens lighter, more save lens materials, and every all corresponding concave surface of eyes can reduce reflective and improves observing effect.11 the utility model glasses can also be that comfort type is closely used glasses.The utility model glasses also can be used for children with amblyopia.12, if lens adopts high-index material, can reduce thickness, weight reduction and can reduce the oblique astigmatism that prism causes.Convex-concave lens concave surface is to eye, is beneficial to prevent on the minute surface dazzling reflectively, helps improving observing effect.
