Abstract
The utility model discloses a polarized lens with double curvature, which comprises a lens and a polarized film. The lens is made of mouldable materials and formed on the polarized film through an injection molding process; the transverse curvature of the lens is larger than the longitudinal curvature thereof; the radius of the transverse curvature of the lens is 58 to 87 mm, and the radius of thelongitudinal curvature is 86 to 132 mm; the thickness of the lens is 1.4 to 3.0 mm; and the lens is made of PC or PA and formed on the polarized film through injection molding. Through the design, the polarized film is combined with the lens firmly to ensure the optical quality of the lens; parasitic light entering eyes on the side edge of the lens is reduced to ensure the definition of scenes and achieve good visual and optical effect. Furthermore, the upper edge and the lower edge of the lens cannot press the face or the cheekbone, and the eyes feel more comfortable when a user wears the lens.
Description
Technical field
The utility model relates to a kind of hyperbolicity eyeglass, and is special relevant with the structure of hyperbolicity polarized lenses.
Background technology
In the prior art, the polarization sunglasses all are in the front of eyeglass or reverse side is pasted polarizing coating by glue and formed, in taping process, because can't guarantee that polarizing coating is stressed evenly, so polarizing coating is pasted not strongly solid, produce bubble even separate easily with between the eyeglass with eyeglass, influence product quality, cause the optical quality of eyeglass poor, eyes have sense of discomfort during use.
In addition, because the spheric glass of single curvature is processed easily, sunglasses all adopt the spheric glass of single curvature, but, the spheric glass of single curvature does not but conform with face's structure of human eye engineering and people, because human eyeball is not as ball, level, the moving range of direction such as vertical is different, about different with the visual field up and down, radian is also different, the optical axis of eyeball body and the optical axis have also differed about 4 and have spent, therefore, the correct lens design of sunglasses should cooperate the structure of eyeball to make optometry reach optimum efficiency, also will consider the structure of human face and the profile of the bridge of the nose and shape of face simultaneously, and the wearer is felt comfortably cool.
The utility model content
The purpose of this utility model is to provide a kind of hyperbolicity polarized lenses, so that polarizing coating combines with eyeglass firmly, guarantees the optical quality of eyeglass, makes the visual optics effect better, wears more comfortable.
To achieve these goals, the technical solution of the utility model is as follows:
The hyperbolicity polarized lenses is made up of eyeglass and polarizing coating, but eyeglass adopts injected plastics material to be molded on the polarizing coating by Shooting Technique, and the cross curvature of eyeglass is greater than longitudinal curvature.
The chordwise curvature radius of described eyeglass is 58～87 millimeters, and the longitudinal curvature radius is 86～132 millimeters.
The thickness of described eyeglass is 1.4～3.0 millimeters.
Described eyeglass employing polycarbonate (PC) or nylon (PA) are injection molded on polarizing coating.
After adopting such scheme, the eyeglass of the utility model injection mo(u)lding is to adopt the material that can melt mutually after identical or the heating with polarizing coating, and eyeglass merges with the surface of polarizing coating in injection molding process, and pressure is even between the two, make between eyeglass and the polarizing coating and combine securely, certainly do not have bubble generation and segregation phenomenon and take place, guaranteed the quality of product, the optical quality of eyeglass is good, glasses are comfortable during use, well lighted, product is frivolous, and is more attractive in appearance.
In addition, because according to human eye engineering and people's face structure, design cross curvature and longitudinal curvature different, make cross curvature greater than longitudinal curvature, the veiling glare that has reduced side enters eyes, keeps the sharpness of scenery, the optometry effect is better, and lower limb can bruising face or cheekbone on the eyeglass, wears to make eyes feel more comfortable.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cut-open view of the present utility model.
Label declaration
Eyeglass 1 polarizing coating 2
Embodiment
As depicted in figs. 1 and 2, be a kind of hyperbolicity polarized lenses that the utility model discloses, form by eyeglass 1 and polarizing coating 2.
Wherein, polarizing coating (PVA) is the film of finishing earlier.
Eyeglass 1 adopt polycarbonate (PC) or nylon (PA) but etc. injected plastics material be molded on the polarizing coating 2 by Shooting Technique.Polarizing coating 2 can be clipped in the centre of eyeglass 1.Eyeglass 1 is to adopt the material that can melt mutually after identical or the heating with polarizing coating 2, and the concrete material that adopts is looked the material of the polarizing coating that uses 2 and determined.
Add man-hour, earlier polarizing coating 2 is processed into required curvature (camber), then polarizing coating 2 is put into injection mold, carry out injection moulding again, eyeglass 1 merges with the surface of polarizing coating 2 in injection molding process, and pressure is even between the two, make between eyeglass 1 and the polarizing coating 2 and combine securely, certainly do not have bubble generation and segregation phenomenon and take place, guaranteed the quality of product, the optical quality of eyeglass is good, glasses are comfortable during use, well lighted, product is frivolous, and is more attractive in appearance.
And the cross curvature of eyeglass 1 is greater than longitudinal curvature, specifically: chordwise curvature radius is 58～87 millimeters, and the longitudinal curvature radius is 86～132 millimeters, and the thickness of eyeglass 1 is 1.4～3.0 millimeters.Like this, eyeglass 1 is more suitable for people's the face's structure and the profile of the bridge of the nose and shape of face, and the veiling glare that has reduced side enters eyes, keep the sharpness of scenery, optical effect is better, and, lower limb can bruising face or cheekbone on the eyeglass 1, wears to make eyes feel more comfortable.
In addition; eyeglass 1 is because of the relation of material and thickness; so in the protection of eyes except that uvioresistant; also can play the function of protection eyes; especially ought be used in motion or some need place to external impact; the defencive function of this kind eyeglass more can show, and this type of eyeglass all can satisfy for every related needs of sunglasses.
