Abstract
The utility model discloses a polarized light contact lens. The polarized light contact lens comprises a bottom membrane coating layer, a middle polarized light material layer and a top lens layer, wherein an optical area is formed in a central area of the top lens layer; the middle polarized light material layer covers the lower part of the optical area of the middle polarized light material layer; the bottom membrane coating layer covers the lower part of the middle polarized light material layer; and the bottom membrane coating layer, the middle polarized light material layer and the top lens layer are tightly adhered together. Aiming to the defect of the contact lens in the prior art, the utility model provides the polarized light contact lens having the anti-dazzling effect.
Description
Technical field
The utility model relates to the contact lenses fields.
Background technology
Contact lenses are a kind of being worn on cornea in order to correct defects of vision or to protect the eyeglass of eyes; contact lenses are not only from having brought very large improvement for the convenience aspect in appearance the ametropia patients such as myopia, long sight, astigmatism; and the visual field is broad, to look thing true to nature; contact lenses are compared frame eyeglasses many advantages; contact lenses do not have the obstruction of picture frame, there is no weight, and wearer's outward appearance be there is no impact; to the personage who likes to be beautiful, especially the women is very suitable.Frame eyeglasses is subjected to the restriction of framework, and contact lenses are not subjected to anyly to block and limit, thereby contact lenses are broader than the visual field of frame eyeglasses.
But when sunlight is incident upon on road surface or the water surface, directly stimulate eyes, make eyes feel to dazzle the eyes, tired, can not look lastingly thing.Particularly when you are driving a car, carrying out out-of-home entertainment when movable, not only affect our work and amusement mood, even affect us to the judgment of image and cause danger; Stand for a long time the sunlight direct irradiation, also can cause the decline rapidly of eyesight, form myopia, long sight, astigmatism or cataract etc.
Summary of the invention
For the deficiency that contact lenses in prior art exist, the utility model provides a kind of polarisation contact lenses with protection effect.
For achieving the above object, the technical solution of the utility model provides a kind of polarisation contact lenses, comprise bottom coating layer, middle part polarisation material layer, top layer mirror plate layers, the central area of described top layer mirror plate layers is formed with optical region, described middle part polarisation layer of material covers is in the below of the optical region of described top layer mirror plate layers, described bottom coating layer is covered in the below of described middle part polarisation material layer, and described bottom coating layer, middle part polarisation material layer, top layer mirror plate layers combine closely.
As the further improvement of utility model, described middle part polarisation material layer covers the pupil surface at least.
As the further improvement of utility model, described top layer mirror plate layers is concave lens or presbyopic lens.
As the further improvement of utility model, the shape of described bottom coating layer, middle part polarisation material layer is complementary.
Owing to having adopted above technological means, the utility model is as a kind of novel contact lenses, and the scattered beam in eliminating and filtering light beam, make light drop into the ocular vision image in the light transmission shaft of the right path effectively, make the nature that gets a clear view.
Description of drawings
Fig. 1 is the layer structure schematic diagram according to polarisation contact lenses of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
Shown in accompanying drawing 1, polarisation contact lenses in the present embodiment, comprise bottom coating layer 1, middle part polarisation material layer 2, top layer mirror plate layers 3, the central area of top layer mirror plate layers 3 is formed with optical region 31, middle part polarisation material layer 2 be covered in top layer mirror plate layers 3 optical region 31 the below and cover at least the pupil surface, bottom coating layer 1 is covered in the below of middle part polarisation material layer 2, and bottom coating layer 1, middle part polarisation material layer 2, top layer mirror plate layers 3 combine closely.Middle part polarisation material layer 2 is arranged between bottom coating layer 1 and top layer mirror plate layers 3, can effectively protects middle part polarisation material layer 2, prevent that also 2 pairs of eyeballs of middle part polarisation material layer from damaging.
In certain embodiment of the present utility model, the shape of bottom coating layer 1, middle part polarisation material layer 2 is complementary.In addition, top layer mirror plate layers 3 of the present utility model can be concave lens or presbyopic lens.
Owing to having adopted above technological means, the utility model is as a kind of novel polarisation contact lenses with anti-dazzle effect, and the scattered beam in eliminating and filtering light beam, make the nature that gets a clear view effectively, greatly facilitates user's Working Life.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the person skilled in the art understand content of the present utility model and implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
