Description
Technical field
The present invention relates to the curved resin lens of the large base of a kind of major diameter.
Background technology
Nowadays the sunglasses on market can only be for not near-sighted crowd, and part businessman is used traditional minor diameter resin eyeglass to make sunglasses eyeglass, and the length of traditional minor diameter resin eyeglass is only between 56～75cm, base curved arc degree 0～600 curved between; The sunglasses eyeglass that the resin lens of this spline structure is made easily causes optical centre cannot aim at central point and the interpupillary distance of eyeglass.In addition, what some businessmans was used customization moves heart eyeglass, but this eyeglass is similar with the effect of prism, can make wearer occur in various degree inadaptable there will be dizzy sensation, to wearer, brings inconvenience.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides the curved band of the large base of a kind of major diameter near-sighted resin lens.
The present invention for achieving the above object, adopts following technical scheme: the curved resin lens of the large base of a kind of major diameter, the diameter of this resin lens changes between 78～90cm, the curved lonely degree of base 300～600 curved between change.
Beneficial effect of the present invention: resin lens of the present invention can manufacture the sunglasses with near-sighted function, wearer does not have dizzy sensation after using, and has increased the result of use of eyeglass.Meanwhile, the resin lens of this structure can be arranged on the mirror holder of disposable type easily.
Accompanying drawing explanation
The structural representation of Fig. 1 front view of the present invention;
The structural representation of Fig. 2 vertical view of the present invention.
Embodiment
Shown in Fig. 1, Fig. 2, be the curved resin lens of the large base of a kind of major diameter, the diameter of this resin lens 1 changes between 78～90cm, the curved lonely degree of the base of this resin lens 1 is arranged on simultaneously 300～600 curved between.Just more approach so on the whole the camber of sunglasses eyeglass, install effect more attractive in appearance natural, have good result of use, after user wears, can there is not dizzy sensation.
The resin lens 1 with above-mentioned diameter and base curved arc degree, can manufacture the sunglasses with near-sighted function.And the resin lens 1 of this structure can make the center of eyeglass accurately aim at the interpupillary distance of eyes, can be not excessive because of picture frame, eyeglass is too small and the problem that causes user cannot aim at eyeglass central point has been avoided causing the dizzy discomfort of user because of interpupillary distance misalignment.In addition, due to resin lens 1 diameter of this structure and base curved larger than traditional, so it also can be arranged on the mirror holder of any model.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (1)
