Abstract
The utility model discloses a double-curvature polarized lens comprising a lens and a polarizing film, wherein the polarizing film is attached on the lens; and radius of transverse curvature of the lens is 52.5mm-87.5mm, and radius of longitudinal curvature thereof is 105mm-262.5mm. Since the radius of transverse curvature of the lens is smaller than the radius of longitudinal curvature thereof, namely the lens is longitudinally flattened, the double-curvature polarized lens leads the polarized lens to be more good-fitting with a pupil of a eyeball after being made into glasses, and greatly shortens the deviation between lens focal distance and eyeball focal distance, thus leading the wearing to be more comfortable and attractive, and improving optical performance.
Description
Technical field
The utility model relates to a kind of hyperbolicity polarized lenses.
Background technology
Only people can see the basis of all things on earth, but are flooded with the light source that makes us perplexing again in the life, and everyone nearly all has similar experience.Summer is scorching, makes eyes be difficult to open, and level and smooth highway, glass architecture is reflective during driving, the glistening light of waves of surface level during fishing, the arclight of electric welding, the strong reflective or the like of snowfield all can stimulate eyes, causes the eyesight discomfort, even cause Whiteout, all these is that the sense of fatigue that they can increase eyes harms one's eyes because high light and reflective, scattered light cause, serious even cause the Personal Risk, cause great inconvenience to people's work, life, outdoor activity.
Polarized lenses is to post light polarizing film on the surface of eyeglass, uses to reach the polarisation effect.Polarized lenses is to utilize light undulatory property principle, adopts technological means to make superfine little grating, and thin to only allowing the light with the polarization direction see through, the utmost point has reduced the direct projection light intensity effectively.Because the polarization angle of most of reflected light, scattered light is changed; can not pass through grating; so polarized lenses has positive effect to elimination reflected light, scattered light; put on polarized lenses, can prevent dazzle, filter mixed and disorderly light, the also clear visual field; can eliminate the ultraviolet ray infringement in the sunshine again; effectively isolate UVA, UVB, the protection eyes, its product is subjected to consumers in general's favor in recent years.
In the prior art, the eyeglass of polarized lenses mostly is the part of spherical crown, its cross curvature is the same with longitudinal curvature, and after this polarized lenses was mixed with glasses, eyeglass and eyeball pupil were not docile, the focal length deviation of the focal length of eyeglass and eyeball is big, optical property is relatively poor, gives the uncomfortable sensation of people when wearing, and is easy to generate visual fatigue, it is also poor to wear effect, attractive in appearance inadequately.
In view of this, the inventor researches and develops, improves at polarized lenses specially, develops a kind of polarized lenses of wearing comfortable, attractive in appearance and good in optical property, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of hyperbolicity polarized lenses of wearing comfortable, attractive in appearance and good in optical property.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of hyperbolicity polarized lenses is made up of eyeglass and light polarizing film; Light polarizing film is attached on the eyeglass; The eyeglass chordwise curvature radius is 52.5mm～87.5mm, and the longitudinal curvature radius is 105mm～262.5mm.
The thickness of described eyeglass is 1.9mm～2.6mm.
The thickness of described eyeglass is 2.0mm, and the eyeglass chordwise curvature radius is 87.5mm, and the longitudinal curvature radius is 131.25mm.
Described eyeglass is concave lens, hyperopic lens or plano lens.
Described light polarizing film is attached on the inside surface or outside surface of eyeglass.
After adopting such scheme, the utility model is because become chordwise curvature radius less than the longitudinal curvature radius lens design, be about to eyeglass and vertically even up, particularly the eyeglass chordwise curvature radius is designed to 52.5mm～87.5mm, the longitudinal curvature radial design is 105mm～262.5mm, after making polarized lenses be mixed with glasses, more docile with the eyeball pupil, dwindled the deviation between the focal length of the focal length of eyeglass and eyeball greatly, wear more comfortable, more attractive in appearance, optical property also is improved.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is a stereographic map of the present utility model;
Fig. 2 is a front elevation of the present utility model;
Fig. 3 is a side view of the present utility model;
Fig. 4 is a vertical view of the present utility model;
Fig. 5 is a cut-open view of the present utility model.
Embodiment
To shown in Figure 5, is preferred embodiment of the present utility model as Fig. 1.
A kind of hyperbolicity polarized lenses that the utility model discloses is made up of eyeglass 1 and light polarizing film 2.
Light polarizing film 2 is attached on the eyeglass 1.Light polarizing film 2 can be attached on the inside surface or outside surface (as shown in this embodiment) of eyeglass 1.
The utility model is because to the particular design of eyeglass 1 chordwise curvature radius and longitudinal curvature radius, make polarized lenses be mixed with glasses after, more docile with the eyeball pupil, dwindled the deviation between the focal length of the focal length of eyeglass and eyeball greatly, wear more comfortablely, more attractive in appearance, optical property also is improved.
