Further, also comprise a diaphragm, the laminating of this diaphragm is arranged at this eyeglass body outer surface.
Wherein, this diaphragm is light polarizing film or color-changing membrane or polarisation variable color composite membrane etc.
Further, this eyeglass body is printing opacity macromolecular material, and diaphragm is firmly attached to the outside surface of this eyeglass body by the job operation of ejection formation in film.
Further, this diaphragm is the convex outward profile with this eyeglass with identical curved surface radian, is sticked respectively on this eyeglass outside surface.
Further, the both wings of this eyeglass are also connected with safe edge.
Further, this safe edge is also provided with four projections.
Further, the inside surface of this eyeglass is provided with four outer shrinkage pools in the corner near outline.
The beneficial effects of the utility model: the little radian curved surface of the curved surface middle position (comparatively flat place, centre) of this optical lens with curved surface adds visual realism; The convex outward structure of eyeglass makes the transition vestige of eyeglass smooth outer surface and cambered surface not obvious according to the design of above-mentioned curved surface radian; The convex outward structure of eyeglass makes eyeglass can uphold to eyes both sides, effectively can filter the high light entering eyes from the side, the effect protecting eyes.Eyeglass bulk material has preferably used heat-resisting, shock proof macromolecular material, decreases eyeglass and is subject to impact failure and the potential safety hazard injuring eyes; The outer shrinkage pool that four projections, inside surfaces on the safe edge of the both wings of this eyeglass, safe edge are provided with, make these eyeglasses when superposition, the projection top of eyeglass is stuck on the outer shrinkage pool of eyeglass above below, makes between eyeglass fixed, reduces in processing, transportation the phenomenon that is damaged.
Accompanying drawing explanation
Fig. 1 is the optical lens with curved surface structural representation of expansion embodiment of the present utility model;
Fig. 2 is that the optical lens with curved surface of expansion embodiment of the present utility model partly cuts open figure.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
basis embodiment:
As the optical lens with curved surface of the utility model basic embodiment, comprising: an eyeglass body, this eyeglass body has convex outward structure, and the radius-of-curvature being positioned at the curved surface of curved surface middle position is 87 ~ 523 millimeters; The radius-of-curvature of the curved surface of the turning joining place between curved surface middle position and position, curved surface both sides is 26 ~ 52 millimeters; Radius-of-curvature near the curved surface of the position, curved surface both sides of bottom margin is 52 ~ 523 millimeters.
expansion embodiment:
Preferably, in order to make optical lens with curved surface have other luminous efficacy, this optical lens with curved surface also comprises the diaphragm that has luminous efficacy, and the laminating of this diaphragm is arranged at this eyeglass body outer surface.This diaphragm can be light polarizing film or color-changing membrane or polarisation variable color composite membrane etc.
Consult by shown in Fig. 1, Fig. 2, as the curved surface polarized lenses of the utility model one preferred embodiment, comprising: an eyeglass body 8 and laminating are arranged at the diaphragm 7 of this eyeglass body 8 outside surface.This eyeglass body 8 has convex outward structure, the radius-of-curvature being positioned at the curved surface of curved surface middle position (facing the comparatively flat place, centre of eyeball) 1 is 87 ~ 523mm(millimeter), this curved surface middle position 1 is similar to plane and faces eyeball because radian is little, so which increase the sense of reality of vision; Simultaneously, the radius-of-curvature of the curved surface of the turning joining place 3 between curved surface middle position 1 and position, curved surface both sides 4 is 26 ~ 52mm, and this curved surface radian gradual change along asymptotic line and made that surface blending is more smooth, zone of transition is no longer so stiff vestige; Radius-of-curvature near the curved surface of the position, curved surface both sides 4 of bottom margin is 52 ~ 523mm.
In one of them best specific embodiment, the radius-of-curvature being positioned at the curved surface of curved surface middle position 1 is 131mm; The radius-of-curvature of the curved surface of the turning joining place 3 between curved surface middle position 1 and position, curved surface both sides 4 is 52mm; Radius-of-curvature near the curved surface of the position, curved surface both sides 4 of bottom margin is 104mm.
The overall convex outward structure of eyeglass, the radian of the radian design of this curved surface makes eyeglass can uphold to eyes both sides, effectively can filter the high light entering eyes from the side, the effect protecting eyes.The manufacturing process of eyeglass body 8 is that the job operation adopting the printing opacity macromolecular material (as PC, PA, PMMA etc.) of high-temperature fusion to carry out ejection formation in film to the mold cavity being positioned with diaphragm 7 manufactures, thus make firm attachment one deck diaphragm 7 on optical polymer eyeglass body 8, the macromolecular material of these eyeglass bodies 8 is preferably selected has heat-resisting, shock resistance material, decreases eyeglass body 8 and is subject to impact failure and injures the potential safety hazard of eyes.This diaphragm 7 has the convex outward profile of identical curved surface radian with this eyeglass body 8, is sticked on eyeglass body 8 outside surface, plays the effect of filtering some high lights.The both wings of this eyeglass body 8 are also connected with safe edge 5, this safe edge 5 is also provided with four projections 2, the inside surface of this eyeglass body 8 is provided with four outer shrinkage pools 6 in the corner near outline, these eyeglasses are when being superimposed, projection 2 top of eyeglass body 8 is stuck on the outer shrinkage pool 6 of eyeglass body 8 above below, be beneficial to obtain the fixed property that stacks between eyeglass body 8, simultaneously, projection 2 has certain height, make to there is gap between upper and lower two eyeglass bodies 8, prevent eyeglass body 8 from the phenomenon of friction damage occurring in process or transportation.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
