Description

Multi-functional reading eyeglass and glasses
Technical field
The present invention relates to presbyopic glasses technical field more particularly to a kind of view it is far close with view between more function with wider passages Eyeglass can be read.
Background technique
With age, eye regulating power is gradually reduced, and nearly difficulty is regarded so as to cause patient, so that near work In, it is necessary to separately add convex lens that can just have clearly near vision except the correction of its static refraction, this phenomenon is known as presbyopia.Presbyopia It is a kind of physiological phenomenon, is not pathological state, be also not belonging to ametropia, is that people step into the vision necessarily occurred after person in middle and old age Problem.
Presbyope needs to wear presbyopic glasses, according to actual needs, presbyopia wearer need it is remote, in, the different distances such as close Vision correcting, it is therefore desirable to different correction of refractive errors functions is integrated on same eyeglass, form multifocal spectacle lens；Existing skill In art, for presbyopia problem, a kind of progressive addition lense piece is had already appeared, progressive addition lense piece is continuously asymptotic by focal power Increased transition region realizes the natural sparse model in view far field and near reading range surface, realizes the focal power consecutive variations of eyeglass, make by remote And the visual field of nearly different distance can blur-free imaging without fracture.
Above-mentioned progressive addition lense piece is worn, although remote use that may be implemented to meet hobby uses effect with close, however, in Between transition region channel it is relatively narrow, after this eyeglass is assembled on spectacle-frame, still remains with the divergence of beam area of large area, lead Cause mesopic vision effect not good.

To realize the above-mentioned technical purpose, the present invention adopts the following technical scheme:
A kind of multi-functional reading eyeglass, including eyeglass ontology, the eyeglass body upper part are view far field, and lower part is that view is close Area, described to be connect near reading range by transition region channel depending on far field, the two sides in the transition region channel are divergence of beam area；It is described The most narrow width in transition region channel is (2/7~4/7) D, and wherein D is eyeglass ontology diameter.
Preferably, the most narrow width in the transition region channel is (2/7) D, visual width >=(5/7) D in the view far field, The visual width of the near reading range >=(4/7) D.
Preferably, the eyeglass body surface is additionally provided with the film of anti-blue light.
The surface of the eyeglass ontology is equipped with one of reflectance coating, photochromic coating and wear-resistant coating.
A kind of multi-functional reading spectacles, including eyeglass and frame, the eyeglass are any eyeglass ontology as above.
Technical solution of the present invention can include the following benefits:
Multi-functional reading mirror of the invention has wider transition region channel, can match the frame of plurality of specifications, can The area for reducing divergence of beam area to the greatest extent realizes better wearing effect；Also, divergence of beam area and visible area junction are gentle Distribution, does not jump；In addition, transition region channel transition is gentle, jump sense when seeing from the distant to the near is eliminated, improves comfortable wearing Property.
The additional aspect of the application and advantage will be set forth in part in the description, and will partially become from the following description It obtains obviously, or recognized by the practice of the application.It should be understood that above general description and following detailed description are only Be it is exemplary and explanatory, the application can not be limited.

Fig. 1 is the multi-functional structural schematic diagram for reading eyeglass described in embodiment of the present invention；
Wherein, 10- eyeglass ontology, 11- regard far field, the near reading range 12-, 13- transition region channel, 14- divergence of beam area.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to each reality of the invention The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each embodiment of the present invention, Many technical details are proposed in order to make reader more fully understand the present invention.But even if without these technical details and base In the various changes and modifications of following embodiment, each claim technical side claimed of the present invention also may be implemented Case.
The embodiment of the present invention relates in one aspect to a kind of multi-functional reading eyeglass, including eyeglass ontology 10, the eyeglass ontology 10 are realized by techniques such as numerical control machine tool cutting, polishings.
10 top of eyeglass ontology is view far field 11, and lower part is near reading range 12, passes through transition depending on far field 11 and near reading range 12 Area channel 13 connects, and the two sides in transition region channel 13 are divergence of beam area 14；The most narrow width in the transition region channel 13 be (2/7~ 4/7) D, wherein D is 10 diameter of eyeglass ontology.
It is understood that eyeglass ontology of the invention can be using any convenient means manufacture, also, the eyeglass ontology can To be made of known suitable material.Such as the method that mirror surface is designed disclosed in US6302540A, and can pass through Commercially available design software such as ZEMAX, VM2000 etc..
It is above-mentioned to be connect near reading range by transition region channel depending on far field, it is to be understood that above-mentioned zone is continuous or local Continuous aspherical, there is no the straight lines of jump between above-mentioned zone.
It is the 2/7~4/7 of eyeglass ontology diameter by widening transition region channel, it is to be understood that it can match a variety of The frame of specification can reduce the area in divergence of beam area 14 to the greatest extent, realize better wearing effect.
Achievable, the curved surface of eyeglass ontology of the present invention can be provided according to such as minor function:
Z=f (x, y)；
According to this function, correct mathematical coordinates directive system within mirror surface O point 3D can be obtained.Wherein O point is determined Adopted domain are as follows: Z=rx2+2sxy+ty2；Wherein r, s, t are the derivative of progressive local surface, r=d2z/dx2, s=d2z/dxdy； T=d2z/dy2。
Eyeglass of the present invention, example can be produced by traditional method for manufacturing lens later by designing mirror surface curved surface Such as processing of numerical control machine tool mechanical, molding, die casting.
Preferably, which the shape of existing blank eyeglass such as is round or oval.
In a preferred embodiment, which has view over focus, and near reading range 12 has view perifocus, In, it is located in the vertical center line of eyeglass ontology depending on over focus and view perifocus；
Wherein, it is located on eyeglass ontology geometry horizontal center line at 15mm depending on over focus, is located at eyeglass ontology depending on perifocus Under geometry horizontal center line at 20mm；
Preferably, this regards the focal length of over focus as 50~80cm, and wearer can facilitate viewing remote using depending on far field Object, such as see TV etc.；This regards the focal length of perifocus as 20~40cm, and wearer can facilitate viewing close using near reading range Apart from object, such as see the mobile phone.
In a preferred embodiment, the most narrow width in transition region channel is (2/7) D, depending on visual width >=(5/ in far field 7) D, visual width >=(4/7) D of near reading range；Wherein, depending on the visual width definition in far field: horizontal where view over focus in view far field The width in face；The visual width near reading range is analogized.
Since transition region channel is wider, so that the visual width depending on far field and near reading range increased, eyeglass side is reduced The diverging region area of edge, it is practical.
