Abstract
The utility model discloses a double curvature lens, of which the transverse curvature is greater than the longitudinal curvature thereof, wherein, the transverse curvature radius ranges from 58 to 87 mm, and the longitudinal curvature radius ranges from 86 to 132 mm. The design of the double curvature lens reduces stray light that is sent into eyes from a side edge, keeps the scenery definition, and has better visual optics effect; and in addition, the upper edge and the lower edge of the lens cannot press a face or cheekbones, so the eyes feel very comfortable when in wearing.
Description
Technical field
The utility model relates to the technical field of eyeglass, and is special relevant with the plano lens structure of employed hyperbolicity.
Background technology
For a long time, the sunglasses that we wore all adopt the spheric glass of single curvature, and this is because the spheric glass of single curvature is processed easily.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, the moving range of level, direction such as vertical is different, different not only with the visual field up and down, radian is also different, and the optical axis of eyeball body and the optical axis have also differed about 4 degree.Therefore, correct lens design 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.
In view of this, the inventor overcomes difficulty of processing according to the human eye engineering, and designs novel eyeglass, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of hyperbolicity eyeglass, makes the visual optics effect better, wears more comfortable.
To achieve these goals, the technical solution of the utility model is as follows:
Hyperbolicity eyeglass, the cross curvature of eyeglass be greater than longitudinal curvature, and chordwise curvature radius is the 58-87 millimeter, and the longitudinal curvature radius is the 86-132 millimeter.
The thickness of described eyeglass is 0.6～1.1 millimeter.
Described eyeglass adopts Triafol T (TAC) or other material to make.
With light polarizing film, can eliminate dazzle and high light on the described eyeglass, the height fluctuating on the place ahead scenery and ground is felt obvious, clear and soft.
After adopting such scheme, the utility model is because cross curvature is different with longitudinal curvature, and to the in addition design especially of cross curvature and longitudinal curvature, the veiling glare that has reduced side enters eyes, keep 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
Embodiment
As depicted in figs. 1 and 2, be a kind of hyperbolicity eyeglass that the utility model discloses, be that the cross curvature with eyeglass 1 designs greater than longitudinal curvature, and the chordwise curvature radius span be the 58-87 millimeter, longitudinal curvature radius span is the 86-132 millimeter.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, the optometry effect is better, and, lower limb can bruising face or cheekbone on the eyeglass 1, wears to make eyes feel more comfortable.
Can not have light polarizing film on the eyeglass 1 of the present utility model, also can be as shown in Figure 2, on eyeglass 1, also has light polarizing film 2, this light polarizing film 2 can be clipped in the centre of eyeglass 1 or be attached to the inside surface or the outside surface of eyeglass 1, be used to eliminate dazzle and high light, the height fluctuating on the place ahead scenery and ground is felt obvious, clear and soft.
