The 4th invention is the purposes of above-mentioned glasses: above-mentioned glasses are to put mirror far away (illustrate: " putting mirror far away " is meant and can gathers and adjusting by synchronous change, keep the custom of binocular integration and adjusting, and the virtual image of observing thing is become than the farther sight glass of observation thing).That is to say that it is the presbyopia glasses that the elderly uses, also can be used as children or teenager and see the glasses of the pre-myopia prevention that nearly thing uses or the glasses of treatment myopia, also can be used as the glasses that farsightedness is used, also can be used as binocular magnifier and use.
The additional technical feature of glasses of the present invention 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 complex optics front interior.4, the distance that the geometric center of complex optics and optical centre depart from is greater than 2 centimetres, and complex optics can be that the concave-convex type lens also can be the planoconvex lens, perhaps, the compound spectacles sheet also can be Fresnel type lens (or claiming Fresnel lens), biconvex or the like.Convex lens in the compound spectacles sheet and prism can be eyeglasses with one, also can be by convex lens and the overlapping compound spectacles sheet that constitutes that connects airtight of another prism together.Lens adopts high-index material, can reduce thickness, weight reduction and can reduce the oblique astigmatism that causes because of prism.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:
Glasses of the present invention and prior art ZL 200620031493.6 " triple prism type presbyopic glasses " compare: the heart degree of moving of eyeglass of the present invention is bigger or perhaps the eyeglass angle of deviation is bigger.So glasses of the present invention 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.Lens of the present invention 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.
The claimed numerical range of the present invention is in order to reach following purpose or effect: 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, just can make glasses 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 so the present invention selects two focuses of glasses to overlap, 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 present invention selects " 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 when the preparation glasses, the eyesight that all meets every eyes in the hope of each eyeglass diopter, if two eyes far point differences then corresponding eyeglass can be different are if two identical then corresponding eyeglasses in eyes far point are understood identical.The present invention regards 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 all are symmetries, 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 glasses applicability of the present invention 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 putting on behind the glasses of prior art eyes has changed custom and has felt 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 common spectacles was 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 glasses of the present invention 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 present invention 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.The compound spectacles sheet of prism and convex lens composite prism is combined into achromatic compound spectacles sheet, and the summation of effect is more superior separately than both for its combined effect.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 convex-concave lens is beneficial to and prevents on the minute surface dazzling reflectively, and the planoconvex lens is subjected to the interpupillary distance restriction little and reflective few, all 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, glasses of the present invention 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 glasses reading of the present invention 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 glasses of the present invention can be used as the glasses of treatment myopia.The glasses that 9 glasses of the present invention use as farsightedness are more comfortable than the spectacles for long sight of two convex lens formations of usefulness of prior art.Glasses of the present invention also can be used for children's myopia using.10, glasses of the present invention as binocular magnifier use binocular magnifier than convex lens lighter, more save lens materials, and every all corresponding concave surface of eyes helps reducing reflective and improves observing effect.11, if lens adopts high-index material, can reduce thickness, weight reduction and can reduce the oblique astigmatism that prism causes.
