Abstract

The utility model provides a kind of expansion scape glasses, including eyeglass, picture frame and temple, the eyeglass is embedded in the picture frame, and the temple connection and the two ends of the picture frame, the eyeglass are provided with an at least row prism positioned at the picture frame with one end that the temple is connected.The utility model expansion scape glasses, which both ensure that, does not disturb the original visual field of wearer, further extends the visual field of wearer.

Description

Expand scape glasses

Technical field

The utility model embodiment is related to lens technologies field, more particularly to a kind of expansion scape glasses.

Background technology

It is 124 degree that human eye normal condition people two, which overlaps the kens, namely in the range of human eye is watched, only this 124 Object in degree visual angle just has third dimension.In the case that user does not change posture in the corresponding scope of above-mentioned angle, change Need to wear specific glasses during viewing visual angle.

Current eyeglass design is generally horizontal glasses and reflection type spectacles, it is possible to achieve the scenery in the specific direction of viewing.

But, above-mentioned glasses due to added on the basis of existing glasses new part cause to block it is original normal The visual field.

Utility model content

Expand scape glasses the utility model proposes one kind, it is therefore intended that expand the field range of wearer, to overcome above-mentioned skill Art problem.

The utility model one kind expands scape glasses, including eyeglass, picture frame and temple, and the eyeglass is embedded in the picture frame, The temple is connected to the two ends of the picture frame, including：

The eyeglass is provided with an at least row prism positioned at the picture frame with one end that the temple is connected.

Further, the spacing in the row prism between prism is 2mm.

Further, the eyeglass can be concavees lens, convex lens or goggles.

Further, in addition to：

Base, the base is arranged at the lower section of the prism, is connected with the bottom surface of the prism.

Further, a length of 1mm in the bottom surface of the prism, is highly 2mm, and the substructure height is 1mm.

Further, the material of the eyeglass is resin or optical glass.

Further, the material of the picture frame and temple is β titanium matter.

The utility model expands scape glasses and utilizes the polylith small prism equivalent with monoblock prism, it is not necessary to wearer's rotary head Portion, with regard to the partial visual field beyond normal viewing angle can be seen.Both it ensure that and do not disturbed the original visual field of wearer, further extended The visual field of wearer.

Brief description of the drawings

Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to The scope of the utility model protection.

Fig. 1 is that the utility model one kind expands scape Glasses structure schematic diagram, as shown in figure 1, the expansion scape glasses of the present embodiment can With including：

Eyeglass 101, picture frame 102 and temple 103, the eyeglass are embedded in the picture frame, and the temple is connected to described The two ends of picture frame, the eyeglass is provided with an at least row prism 104 positioned at the picture frame with one end that the temple is connected.

Specifically, it is 124 degree that two of normal condition people, which overlap the ken,.That is the scope watched in human eye Interior, the object only in this 124 degree of visual angles just has third dimension.Namely the thing only watched in this 124 degree of two coincidence kens Body section, has exceeded 180 degree, so that foring third dimension.The simple eye comfortable ken is 60 degree, only this 60 degree of simple eye scope Interior object, people can see that human eye can be focused on.Peripheral part of 30 degree more than horizontal direction angle of visibility is referred to as The visual field is induced, the remaining light of eyes is commonly called as, is human eye in fact and insensitive scope, that is, can not see.Therefore when me Want to see clearly left back either the scenery of right back when, we will first rotate eyeball to certain angle or rotation head, But scenery is in the case of the side to the rear of side, the object that rotation eyeball is seen is often not clear enough, therefore certainly will need to rotate Head.

Further, the spacing in the row prism between prism is 2mm.

Specifically, one end that the present embodiment is connected on eyeglass with temple, by adhesives such as glass cements on minute surface Multiple prisms are fixed with, the requirement to the adhesive is clear, colorless, so as to not interfere with normal printing opacity.Further, institute The a length of 1mm in bottom surface of prism is stated, is highly 2mm.The width of conventional ophthalmic len is in 54~57mm, highly in 30~32mm, therefore Often row can place 10~15 prisms, and 10 rows are placed altogether, spacing about 2mm often be arranged, to ensure that light will not be interfered with each other.Such as Fig. 2 Shown, the prism between often arranging joins end to end, i.e., the plane of light incidence of previous prism is connected with the transmission plane of latter prism, Therefore a zigzag fashion is integrally formed.The extended line of above-mentioned all light of the light for inciding prism through refraction is extended to In the eyes for the people for wearing the prismatic glasses.

Further, the eyeglass can be concavees lens, convex lens or goggles.As shown in figure 3, also including：

Base 301, the base is arranged at the lower section of the prism 302, is connected with the bottom surface of the prism.Wherein, 303 be eyeglass.

Specifically, the eyeglass of the present embodiment be convex lens or concavees lens, can be by beating in the case of being not level crossing The base portion is ground, the angle of minute surface so that base portion is fitted preferably is bonded on eyeglass.The present embodiment substructure height For 1mm.

As shown in figure 3, the material of prism is optical glass, refractive index is typically typically between 1.523~1.9.From The purpose of glass material is that refractive index is big, reduces thickness.Prism is equilateral triangle, and the wedge angle of prism outwardly convex is 60 degree, above noodles part is calculated, and the bending angle after light refraction is about at 48 °~90 °, therefore regarded even more than horizontal direction The light outside field range that more than 30 degree of wild angle, smoothly can also enter human eye, as shown in figure 3, multiple small ribs by refraction The effect of mirror and a whole big prism are equivalent, the light that directional light incidence is reflected be also it is parallel, i.e. light after prism incidence, The scenery that can be drawn close through superrefraction to human eye direction beyond certain angle, such script visual line of sight, can make by this method Wearer can be without moving very big amplitude with regard to that can see.

Further, the material of the eyeglass is resin or optical glass.

Further, the material of the picture frame and temple is β titanium matter.The picture frame and temple elasticity of the material are good, intensity Greatly.

The prism of prior art is typically monoblock, stops the normal visual field, can only see the scenery in specific direction, together When wear aesthetic property and practicality and can be substantially reduced because of the discomfort of subject.

Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly The scope of each embodiment technical scheme of type.
