Description

Watch the eyeglass device of display screen

Technical field

The present invention relates to the optometric technology field.

Background technology

Watch nearby display screen need use the regulatory function of eyes, regulate anxiety and can make eye fatigue.Put on the positive lens glasses (for example " triple prism type presbyopic glasses " patent No. ZL200620031493.6) of prior art though watch nearby display screen can loosen the adjusting of eyes, its shortcoming is the distance that can not control well between glasses and the display screen.According to optics formula 1/u+1/v=1/f as can be known glasses and display screen apart from the u change virtual image of glasses and display screen is changed apart from v, because observer's activity will inevitably often change the position of observer's eyes unconsciously when watching, often change the distance between glasses and the display screen, so the display screen virtual image meeting distance of seeing by the glasses that are worn on observer's head changes, the adjusting of eyes also can be loosened suddenly thereupon and be nervous suddenly, and the continuous variation of the adjusting of eyes makes eye fatigue easily.On the one hand, whether comfortable the stability of distance very big to the eyes influence of enduring hardships between glasses and the display screen; On the other hand, the size of distance is very big to the influential effect that glasses loosen the eyes adjusting between glasses and the display screen.For example the distance of glasses and display screen near or emmetropia viewing effect best (this is because the display screen virtual image at infinity during u=f, loosens most when facing soon the infinite distance) when equaling focal length; Do not see Chu's (this is because u〉f then do not become the virtual image) or eyes regulates with strength and just can see the uncomfortable and easy fatigue of eyes clearly greater than becoming the mist picture easily behind the focal length; Image is nearer more at most less than focal length for the distance of glasses and display screen, and the nearer relaxation effect when far away than image of image is poor.Optimum distance scope between glasses and the display screen very little (this be because u less than and during near f, the variation that u is very little all can make v produce huge variation), so be difficult to keep the distance of the best when using the glasses that are worn on observer's head to watch the display device of independently placing with display screen, in fact can only make object distance be far smaller than focal length in order to see and reserve move place clearly, keep image more nearby, cause glasses can not well loosen the set and the adjusting of eyes.

Summary of the invention

At the existing glasses stable defective of object distance that is hard to keep, the technical matters that the present invention watches the eyeglass device of display screen to solve is: utilize glasses to put adjusting and set that image far away loosens eyes, arrive the distance of glasses by the virtual image that comes control display screen with the distance between support control display screen and the glasses, reach stable image distance, stably loosen the effect of the adjusting and the set of eyes, improve observing effect, allow the observer feel comfortable, tireless purpose.

The technical scheme of first invention is: the eyeglass device of watching display screen, the eyeglass of glasses can loosen the set and the adjusting of eyes, light is from changing direction facing to the pupil part by meeting behind the glasses, it is characterized in that having the support of distance between control glasses and the display screen, display screen is arranged on this support or the special-purpose member that connects or lay display device is arranged, on this support, also have glasses, eyeglass facing to left eye in the glasses is symmetrical with the eyeglass that faces toward right eye, and directional light by in the glasses facing to the real focus that forms behind the eyeglass of left eye with by facing toward distance between the real focus that forms behind the eyeglass of right eye less than 0.035 meter, the focal length of eyeglass * 1.1〉the focal length ÷ (focal length of eyeglass+1) of distance 〉=eyeglass between the position of glasses and display screen, the unit of its middle distance is a rice.

" display screen is arranged on this support or the special-purpose member that connects or lay display device is arranged " described in the technical scheme is that back-and-forth method arranged side by side is summarized, and promptly " display screen arranged " or " having only the special-purpose member that connects display device " or " special-purpose member of laying display device is arranged " is the concrete feature of alternative arranged side by side.That is to say in the above-mentioned eyeglass device of watching display screen or display screen (can comprise union piece) is arranged, or do not have display screen but have only the special-purpose member (display screen that will watch is on the display device that does not belong to this device) that connects or lay display device.Display device is meant computer monitor, or mp4, or DVD, or LCDs, or e-book, or mobile TV, or mobile phone, or game machine or the like has the device of display screen." being used to connect or lay the special-purpose member of a display device " is that upperseat concept is summarized, for example the special-purpose member that support and display device are bound up is to paste coupling compoonent or belt or spring clamp or screw clamp, or screw ... Deng member, the special-purpose member that will use when display device is placed in certain position on the support for example is placement platform or hook or the container with anchor clamps ... or the like member." eyeglass of glasses can loosen the set and the adjusting of eyes " or " can loosen the glasses of the adjusting and the set of eyes " is function or effect characteristic, and the basic characteristics of this glasses are that the distance of eyeglass and eyes is near and understand inside deviation by the light at pupil place by facing to the eyeglass of pupil of both eyes the time when directional light when watching.Eyeglass can be a convex-concave, also can be planoconvex, also can be biconvex, or the like." support of distance between control spectacle sight glass and the display screen " or can change the adjustable trestle (for example Figure 29, Figure 30, Figure 39, Figure 40, Figure 43 etc.) of length, or fixed bracket (for example Figure 38, Figure 45), etc." in the glasses be symmetrical facing to the eyeglass of left eye " with eyeglass facing to right eye be meant facing to the eyeglass of left eye and the diopter that faces toward the eyeglass of right eye equate, prism degree is identical, the substrate of prism is towards being symmetrical." directional light by in the glasses facing to the real focus that forms behind the eyeglass of left eye with by facing toward distance between the real focus that forms behind the eyeglass of right eye less than 0.035 meter " be the key element such as diopter, prism degree, position to eyeglass in the glasses and the description (for example Fig. 8) of mutual relationship thereof.The focal length of " the focal length ÷ of the distance 〉=eyeglass between the focal length of eyeglass * 1.1 〉=glasses and the display screen (focal length of eyeglass+1), the unit of its middle distance are rice " middle eyeglass is meant the focal length of positive lens or refers to the focal length of " moving heart positive lens ".Equal the focal length of eyeglass or equal 5 meters or equal 4 meters or equal 3 meters or equal 2 meters or the like comprising the distance between glasses and the display screen.

Additional technical feature of the present invention is as follows:

1, the eyeglass of watching the corresponding eyes of glasses in the eyeglass device of display screen is made of " existing positive lens lens " and prism or combination or compound or integrator, two concave surfaces are arranged on the lens surface of corresponding eyes, the concave surface on the left side faces left eye, and the concave surface on the right faces right eye (for example Fig. 4, Fig. 7, etc.)." existing positive lens lens " is meant that optical centre faces toward the positive lens lens of the concave surface of pupil, eyeglass facing to the convex-concave of the prior art of eyes, its surface can be sphere also can be aspherical lens.Optical centre works to loosen the eyes adjusting facing to two " existing positive lens lenses " of eye pupil in the glasses, two substrates all prism in the inboard work to loosen binocular integration, and two " moving heart positive lens " can loosen the set and the adjusting of eyes simultaneously.

2, in the glasses facing to the eyeglass of left eye and mutual relationship facing to the eyeglass of right eye be (matching relationship between its diopter, prism degree, the position is) when the directional light irradiation glasses by facing to the focus that forms behind the eyeglass of left eye with overlap (for example Fig. 9) by facing toward the focus that forms behind the eyeglass of right eye.Focus is a hot spot, and focus overlaps and to be meant that these two hot spots are overlapped or overlapping fully.

3, eyeglass in the glasses is the eyeglass that can weaken aberration, that is to say facing to the eyeglass of left eye and facing on the eyeglass of right eye the overlapping prism that connect airtight on other lens surface of a substrate in the outside all respectively arranged, the refractive index of this prism material is different with the overlapping eyeglass that connects airtight, the substrate of this prism towards with substrate in the substrate of the prism of inboard towards opposite, or the substrate of this prism is the featheredge (for example Figure 19, Figure 20, Figure 21, Figure 22, shown in Figure 23) towards " moving heart lens ".

4, watching the structure of glasses in the eyeglass device of display screen is following one of several (summarizing with back-and-forth method arranged side by side): it is all (for example shown in Figure 3 in the overlapping formation of connecting airtight of the prism of inboard with a substrate facing to eyes " existing positive lens lens " by one that the eyeglass of glasses is that two " the moving heart positive lens " of settling about corresponding eyes and each " are moved heart positive lens ".The prism of substrate " in the inboard " meaning be corresponding eyes prism substrate towards inwardly all be or all be inwardly on the upper side the side or all be inside side on the lower side); Perhaps, the eyeglass of glasses be two " the moving heart positive lens " of settling about corresponding eyes and each " move heart positive lens " all by one facing to eyes " existing positive lens lens " and a substrate in the incorporated eyeglass of the prism of inboard (for example shown in Figure 4); Perhaps, in the glasses eyeglass of corresponding eyes be an one eyeglass and it be by facing to two that settle about eyes " existing positive lens lenses " with facing to two substrates settling about eyes in the incorporated eyeglass of the prism of inboard (for example shown in Figure 7); Perhaps, the eyeglass of glasses is to face toward at the bottom of two that settle about eyes at the prism of inboard and the double-layer lens (for example Figure 13, shown in Figure 15) that constitute facing to two that settle about eyes " existing positive lens lenses "; Perhaps, the eyeglass of glasses is " two prisms are connected in one in bases " eyeglass and the double-layer lens (for example shown in Figure 17) that faces toward two positive lens lenses formations of settling about eyes; Perhaps, the double-layer lens of glasses is made of " two prisms are connected in one in bases " eyeglass and an integrally formed lens that is comprising two " existing positive lens lenses "; The overlapping prism that connect airtight on other lens surface of a substrate in the outside perhaps also respectively arranged, the refractive index of this prism material different with the overlapping eyeglass that connects airtight (for example Figure 19, Figure 20, Figure 21, Figure 22, shown in Figure 23) on the eyeglass of corresponding left eye and right eye in above-mentioned various glasses; Perhaps, the eyeglass of glasses is that the following middle part of the common positive lens that uses of eyes and this positive lens has depression, and the photocentre of this positive lens is (for example shown in Figure 28) in bridge of the nose position; Perhaps, the eyeglass of glasses is achromatism positive lenss that there is depression at a following middle part, and its photocentre is (for example Figure 25 and shown in Figure 26) in bridge of the nose position.

5, the support of distance is to adjust the support that changes distance between glasses and the display screen between control glasses and the display screen.This support can be various forms of adjustable trestles: for example be telescope cribbing or flexible bellows-type support or scissors telescope support or folding bracket or hinge link-type support or screw support or parallel mobile four-bar support, or the like; For example a kind of adjustable trestle, adjust this support and not only can make distance between glasses and the display screen equal numerical value in " focal length of 1.1 * lens " to " the focal length ÷ of lens (focal length of lens+1) " scope, also can make distance between glasses and the display screen outside this scope; For example another kind of adjustable trestle is adjusted this support the distance between lens and the display screen is only being changed less than " 1.1 * lens focal length " and in greater than the scope of " the focal length ÷ of lens (focal length of lens+1) ".The virtual image of the display screen of seeing by glasses when the distance between lens and the display screen equals the focal length of lens at infinity, when the distance between lens and the display screen equal " lens * V ÷ (and the virtual image of the display screen of seeing by glasses during the focal length of lens+V) is at V rice at a distance; for example V equal 1 o'clock display screen the virtual image 1 meter distant place, V equals the virtual image of 5 o'clock display screens 5 meters distant places.

6, on the support that can adjust distance between change glasses and the display screen, align member is arranged.Align member is upper summary or functional characteristic, and for example align member is the fastening screw on the telescopic tube cribbing, or the set screw nail, or the like.

7, watch and have one in the eyeglass device of display screen and supporting the supporting bracket of " glasses, display screen or connection or lay the support of distance between special-purpose member, control glasses and the display screen of display device ".That is to say this supporting bracket: or supporting the supporting bracket of " support of distance between glasses, display screen and control glasses and the display screen "; Or supporting the supporting bracket of " support of distance between glasses, the special-purpose member of laying display device and control glasses and the display screen "; Or supporting the supporting bracket of " support of distance between glasses, the special-purpose member that connects display device and control glasses and the display screen ".This supporting bracket is to be the support of stilt with the object and to be adjustable trestle, adjusts supporting bracket and the position of glasses and display screen together can be moved.This supporting bracket can be various forms of adjustable trestles, for example is desk-top support, or presss from both sides desk-top support, or wall bracket, or support etc. on the spot; For example be telescope cribbing or scissors telescope support or hinge connecting rod rack or fluid pressure type support, vapour-pressure type support or the like.

8 or, watch in the eyeglass device of display screen a wear-type base for supporting is arranged.With observer is stilt, the wear-type base for supporting can be cap formula or helmet-type or bandage type, or the like.It is the base for supporting that supports " glasses, display screen or connection or lay the support of distance between special-purpose member, control glasses and the display screen of display device ".

9, it is optical filtering that the coating or the eyeglass that weaken harm ray protection eyes are arranged on the eyeglass of glasses.

Two inventions are arranged under a total inventive concept.Its specified features is: the support that distance between control glasses and the display screen is arranged, display screen is arranged on this support or the special-purpose member that connects or lay display device is arranged, the glasses that can loosen the adjusting and the set of eyes on this support in addition (on the support feature of glasses be light from facing to the pupil part by changing the i.e. deviation to the inside of direction behind the glasses, common practise is thought: optical centre should be aimed at pupil, make light from facing to the pupil part by the glasses rear to remaining unchanged).

The technical scheme of second invention is: the eyeglass device of watching display screen, the eyeglass of glasses can loosen the set and the adjusting of eyes, light is from changing direction facing to the pupil part by meeting behind the glasses, it is characterized in that having the support of distance between control glasses and the display screen, display screen is arranged on this support or the special-purpose member that connects or lay display device is arranged, also have glasses on this support, the glasses on the support are be combined with each other glasses of formation of glasses that above-mentioned various glasses and user are accustomed to often wearing.Other is identical except that glasses.The mutual relationship of right and left eyes eyeglass is: facing to the lens prism substrate of left eye towards with facing to the lens prism substrate of right eye towards being symmetrical, half interpupillary distance * 100 of the horizon prism degree ÷ left eye at the diopter ≈ pupil of left eye place of left eyeglass lens on the glasses of often wearing facing to the diopter-custom of the eyeglass of left eye; Half interpupillary distance * 100 of the horizon prism degree ÷ right eye at the diopter ≈ pupil of right eye place of right eye eyeglass on the glasses of often wearing facing to the diopter-custom of the eyeglass of right eye; The diopter ≈ of left eyeglass lens faces toward the diopter of right eye eyeglass on the glasses that the diopter-custom of the eyeglass of right eye often wears on the glasses of often wearing facing to the diopter-custom of the eyeglass of left eye; The horizon prism degree at the horizon prism degree ≈ pupil of right eye place at pupil of left eye place.1.1 ÷ (diopter of left eyeglass lens on the glasses of often wearing facing to the diopter-custom of the eyeglass of left eye)〉distance between the position of glasses and display screen 1 ÷ (face toward the diopter-custom of eyeglass of left eye frequent wear glasses on diopter+1 of left eyeglass lens).Or, facing to the diopter of left eyeglass lens on the glasses that diopter=(distance between the position of 1/ glasses and display screen)-custom is often worn of the eyeglass of left eye.The unit of formula middle distance is a rice.The convex lens diopter be on the occasion of, the diopter of concavees lens is a negative value.

Beneficial effect

1, " loosening the glasses that eyes are regulated and gathered " and " support of distance between control glasses and the display screen " combination back supports each other that on function the technique effect after the combination is more superior than the summation of each technical characterictic effect.Because the adjusting of eyes or set are with the image distance variation, the distance of the display screen virtual image changes with object distance in the glasses, and the stability of the size of object distance and object distance directly influences glasses and loosens eyes adjusting and the effect of gathering.So glasses cooperate with " support of distance between control glasses and the display screen ", can stablize by keeping object distance, make image distance stable, reduce eyes and regulate the frequency that changes, and loosen the adjusting and the set of eyes, make that eyes are comfortable endures hardships by controlling suitable object distance.Have only with stable distance between support maintenance glasses and the display screen to keep the virtual image of display screen to be stabilized on the far point of eyes, allow glasses reach and loosen the optimum efficiency that eyes are regulated and gathered.2, select " the focal length ÷ of the distance 〉=eyeglass between the position of glasses and display screen (focal length of eyeglass+1) " be for the distance that makes the glasses and the display screen virtual image greater than 1 meter, if having, the too little effect that can influence glasses of object distance, glasses do not loosen the effect that eyes are regulated and gathered.Object distance is during less than the eyeglass focal length, and the big more image distance of object distance is big more.When object distance equaled the eyeglass focal length, the virtual image of display screen at infinity in the glasses.When object distance during, help farsightedness and watch or help emmetropia and temper eyes greater than focal length and less than the focal length of eyeglass * 1.1.3, select " directional light by in the glasses facing to the real focus that forms behind the eyeglass of left eye with by facing toward distance between the real focus that forms behind the eyeglass of right eye less than 0.035 meter " be that eyes are comfortable endures hardships in order to allow.Will destroy eyes and regulate and integrated interlinked custom the uncomfortable and easy fatigue of eyes if glasses only change set that the adjusting of eyes do not change eyes.Positive lens with real focus can loosen the adjusting of eyes, two real focus less than interpupillary distance then glasses can loosen binocular integration.Distance between these two real focus is more little, when observing by glasses the set of eyes and adjusting cooperate rule just to observe near the eyes bore hole more the time custom, the eyes that custom is watched with bore hole are just comfortable more.So the distance between these two focuses during less than 0.035 meter eyes pleasant, so because pleasantly relatively endure hardships.And the distance between these two focuses is during less than 0.035 meter, and glasses are not limited by interpupillary distance, are applicable to the observer that interpupillary distance is different.The glasses of distance between these two focuses during less than 0.035 meter, be not only applicable to be accustomed to the people that bore hole is watched, be applicable to that also people that custom wears the left eyeglass lens spectacles identical with right eye eyeglass diopter (for example, some custom is worn the people that photocentre is aimed at the identical spectacles of the left and right sides eyeglass diopter of pupil, the rule with bore hole is different for the cooperation custom of its binocular integration and adjusting, it is more comfortable to wear the glasses that two real focus do not overlap), be applicable to that also custom wears the people of the little spectacles of left eyeglass lens and right eye eyeglass diopter difference.4, select " facing toward the eyeglass and the eyeglass symmetry that faces toward right eye of left eye in the glasses " to help the versatility and the comfortableness of glasses.Prior art can be used two different lenses of diopter according to the weak-eyed of two eyes, the essentially identical observer of eyesight that two lenses that diopter is identical are applicable to two eyes, image is on the far point of two eyes simultaneously, but the image of seeing is far and near different, and glasses have changed the rule that cooperates of set with the adjusting of bore hole.No matter two eyes of the present invention have or not weak-eyed, all select the identical lens of diopter, its purpose unlike the prior art, the present invention be eyes when eyes are watched by glasses set and adjusting cooperate rule near or custom when equaling the eyes bore hole and observing, allow eyes are comfortable endures hardships.If the far point difference of two eyes also is in the far point of another eyes when then image is on the far point of eyes, the image distance of seeing is identical.And, do not consider whether observer's eyes are variant, select left and right sides eyeglass symmetry to help strengthening the versatility of glasses.Highly versatile helps producing in batches.5, the eyeglass of glasses is by " existing positive lens lens " and prism or combination or compound or integrator formation, two concave surfaces are arranged on the lens surface of corresponding eyes, each concave surface is only facing to eyes, this concave surface can not only make the prompt hair of eye leave eyeglass and far make and feel comfortable, and can weaken the reflective interference of the aberration and the minimizing minute surface of lens, help improving observing effect.Glasses are compared with the shared positive lens of eyes has that the mirror body is thin, weight is lighter, the advantage of saving lens materials.6, the advantage that the eyeglass left-right symmetric of glasses and focus overlap is: when eyes are seen the virtual image set with regulate between cooperation the same when seeing real-world object at a distance just, gather with cooperating of adjusting and meet physiologic habit, so comfortable enduring hardships.No matter the virtual image a long way off or on hand, it cooperated the influence that is not subjected to object distance or image distance with regulating synchronous interaction in set when eyes were seen the virtual image; No matter whether the eyes far point of different observers is identical, different observers uses the effect of same glasses can reach all the same when seeing material object of adjusting when allowing eyes see the virtual image, set.Observing effect was equivalent to the shared positive lens of eyes and watched (as Figure 10, shown in Figure 11) this moment, the effect of glasses is not subjected to the influence of two spacings of observer (interpupillary distance) size, as long as sight line is passed through lens, interpupillary distance big a bit or a little bit smaller different observers all can use same glasses, effect is all good; The eyeglass left-right symmetric of glasses, be not subjected to user's interpupillary distance restriction, be not subjected to the characteristics of two far point difference limit of user to help producing in batches, save cost, conveniently sell and buy.7, can produce aberration because deviation takes place during by eyeglass pupil place light, sense influenced observing effect as layering when eyes were observed.Overlappingly on the eyeglass connect airtight the prism that one deck can weaken aberration, can improve observing effect, make image clear, make the eyes indefatigability.The aspherical eyeglass lens of correcting " aberration tiltedly looses " aberrations such as " visual field bendings " also helps improving observing effect.8, the glasses of the shared positive lens of eyes compare with magnifier: fundamental purpose is different, the fundamental purpose of glasses and main effect are to loosen the adjusting of eyes and set (it is less important or subsidiary amplifying the visual angle), and the fundamental purpose of magnifier and main effect are to amplify visual angle (adjusting of loosening eyes attaches); The area of the magnifier of general amplification display screen is all greater than display screen, and magnifier is but nearer from display screen from eyes during use.And glasses are near eyes outlying observation thing.Because glasses are seen the bigger visual field from the nearer limited area of eyeglass that can make full use of of eyes, so the lens area is little than the area of magnifier.Eyes help utilizing the positive lens of small size to be seen near glasses with great visual angle display screen being beneficial to the saving cost, reducing the difficulty of making lens; The following middle part of positive lens has depression can reduce the influence of the gas in nose or nostril, makes the glasses of a positive lens nearer from eyes.9, adjust the distance that changes between glasses and the display screen and can adjust the distance that changes the display screen virtual image.Because the far point difference of different observers, so the object distance difference that different observers needs.When different observers uses this device; change object distance selection image distance by adjusting support, can make the virtual image of display screen remain on the far point or the optimum position, fully loosen the adjusting and the set of eyes; eyes are watched indefatigability for a long time, are beneficial to the pre-myopia prevention of protection eyes.Utilize the support of distance between control glasses and the display screen that the display screen virtual image is remained on than the far point of pseudomyopia and watch slightly at a distance, increase distance gradually, can be in use far treat myopia and train on is good by seeing according to effect.10, watch that to have what the position of glasses and display screen was together moved in the eyeglass device of display screen be the support of stilt with the object, help glasses are moved and remain on observer's eyes front, reach and make the comfortable purpose of enduring hardships of observer.Be that the support of stilt not only can alleviate the observer and wears the mirror load-bearing with the object, and utilize the position of support control glasses also just to control the position of eyes that the position of control eyes can be rectified and watched posture, so this device can be corrected the bad posture of watching.The needs that also can adapt to the observer select more comfortable posture to watch.Perhaps, watch in the eyeglass device of display screen the wear-type base for supporting is arranged, the wear-type base for supporting can supporting display screen, the weight of glasses etc., helps that glasses are remained on the eyes front to watch, make the observer comfortable, endure hardships, convenient.11, support each other that on function the technique effect after the combination is more superior than the summation of each technical characterictic effect after the support of distance, the glasses that loosen binocular integration and adjusting, this three's combination of display screen between control glasses and the display screen.Support control object distance helps glasses and gives full play to the optimum efficiency that loosens eyes adjusting and set.Glasses can will watch display screen to become the virtual image of watching display screen, use glasses to watch the distance that helps shortening display screen and eyes, the shortening display screen helps increasing the eyes visual angle to the distance of glasses, and glasses itself also increase the eyes visual angle, and increase eyes visual angle helps using the display screen than small size.Replace the bigger display screen of area can save cost with the less display screen of area.Can in the picture that amplifies display screen, make the picture of display screen become far away after support, glasses and the display screen combination, make image distance best and stable.Help loosening eyes and regulate and set, reduces unnecessary variation, can make that eyes are comfortable endures hardships, can prevent the myopia that closely causes because of seeing for a long time, can learn usually or amusement in treat pseudo-myopia.The left and right sides eyeglass of glasses is symmetrical in 12, the first technical schemes, and the glasses in second technical scheme do not require left and right sides eyeglass symmetry, and its versatility is poor, only is suitable for specific custom people with glasses's special use.Because the people that custom is worn the discrepant glasses of left and right sides eyeglass, the adjusting of his eyes changes with the custom that cooperates of set, do not wear the glasses worn of custom and see that thing is just uncomfortable, his bore hole is watched and can be felt to feel bad and fatiguability, and he puts on glasses that custom wears and watches and be equivalent to emmetropia and watch with bore hole.So second technical scheme is equivalent to glasses that his custom is worn and the glasses of first technical scheme combine.The glasses of left and right sides eyeglass symmetry and the discrepant glasses of left and right sides eyeglass are compound to have constituted second technical scheme.Though these two scheme optometric technology feature differences, purpose all is for the adjusting of stably loosening eyes and set, allows eyes are comfortable endures hardships.
