Abstract
The utility model discloses color astigmatic contact lenses. The color astigmatic contact lenses comprise bottom film-coating layers, middle pigment layers and a top lens layer, wherein the bottom film-coating layers are stacked from bottom to top in sequence; the middle pigment layers are formed on the bottom film-coating layers; the top lens layer is formed on the middle pigment layers; the top lens layer comprises a first surface and a second surface, wherein the first surface is provided with a first curvature radius for myopia adjustment or hyperopia adjustment; and the second surface is provided with a second curvature radius for astigmatism vision adjustment. The color astigmatic contact lenses are used for solving the technical problems in the prior art, and the color astigmatic lenses, which can be used for effectively preventing pigment from dropping and solving the astigmatism adjustment, are provided.
Description
Technical field
The utility model relates to the contact lenses fields.
Background technology
Astigmatism is a kind of ametropia situation of eyes, and is inconsistent relevant with the flexibility of cornea and lens surface.The mankind's eyes are not that perfectly the cornea of some eye is more curved at the radian of a certain angular regions, and other angular regions are more smooth.Cause the reason of astigmatism, make the meridianal refractive index of different directions inconsistent because the flexibility of cornea or these different directions of lens surface is inconsistent exactly, make through these meridianal external lights and can not be gathered in same focus.Like this, light just can not focus on exactly and form image clearly on retina, and this situation just is called astigmatism.And after colorful contact lens occurs, need to find and a kind ofly astigmatism can be regulated the technical scheme of perfect adaptation with it.
Summary of the invention
The deficiency that exists in order to overcome prior art, the purpose of this utility model is to provide a kind of can have astigmatism functions concurrently, effectively prevent that pigment from coming off and the astigmatic contact lenses of compact colour.
For achieving the above object, the technical solution of the utility model provides a kind of colour astigmatic contact lenses, comprise the bottom coating layer that stacks gradually from top to bottom, be formed at middle part uvea on the coating layer of described bottom, be formed at the top layer mirror plate layers on the uvea of described middle part, described top layer mirror plate layers has first surface and second surface, described first surface has the first curvature radius for myopia or long sight adjusting, and described second surface has the second curvature radius for astigmatic visual accommodation.
Further improve as the utility model, the central area of described top layer mirror plate layers is formed with the optical region that is covered in pupil, the central area of described middle part uvea, bottom coating layer forms the hollow out zone corresponding with the optical region of described top layer mirror plate layers, and described bottom coating layer, middle part uvea, top layer mirror plate layers combine closely.
Further improve as the utility model, described middle part uvea is the cover part iris region at least.
Further improve as the utility model, described first surface is positioned at the upper surface of described top layer mirror plate layers, and described second surface is positioned at the lower surface of described top layer mirror plate layers.
Further improve as the utility model, described bottom coating layer, the uveal shape in middle part are mated mutually.
Owing to having adopted above technological means, the utility model can prevent effectively that pigment from coming off and having solved the problem of astigmatic adjusting, thereby has realized beautiful and health and deposited.

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.
As shown in Figure 1, the colored astigmatic contact lenses that the present embodiment proposes, comprise the bottom coating layer 1 that stacks gradually from top to bottom, be formed at middle part uvea 2 on the coating layer 1 of bottom, be formed at the top layer mirror plate layers 3 on the uvea 2 of middle part, bottom coating layer 1 solidified forming is on specific die head, wherein, bottom coating layer 1, top layer mirror plate layers 3 adopt same material, make after curing whole comparatively firm in the process of combination, in conjunction with after the center thickness of eyeglass be 0.08 ± 0.02mm.Due to middle part uvea 2 cover part iris region at least, this middle part uvea can form various decorative pattern by mould, also can make it present various color by the adjustment to coat of colo(u)r, presents multi-effect thereby make after wearing.
Can find out from accompanying drawing 1 and accompanying drawing 2, the central area of top layer mirror plate layers 3 is formed with the optical region that is covered in pupil, the central area of middle part uvea 2, bottom coating layer 1 forms the hollow out zone corresponding with the optical region of top layer mirror plate layers 3, and bottom coating layer 1, middle part uvea 2, top layer mirror plate layers 3 combine closely.Top layer mirror plate layers 3 has first surface 31 and second surface 32, first surface 31 is positioned at the upper surface of top layer mirror plate layers 3, second surface 32 is positioned at the lower surface of top layer mirror plate layers 3, wherein, first surface 31 has the first curvature radius for myopia or long sight adjusting, and second surface 32 has the second curvature radius for astigmatic visual accommodation.
as accompanying drawing 2, accompanying drawing 3 is with shown in accompanying drawing 4, the both sides up and down of top layer mirror plate layers 3 have thinned region 33, and the left and right sides has top rake district 34, its net result presents the thin shape of the thick side of the side shown in accompanying drawing 3, and the shape of the both sides wedge angle shown in accompanying drawing 4, the technique effect of this profile is: when wearing rear Rotation of eyeball, because a thicker side is also heavier, the effect that has automatic location under Action of Gravity Field, thereby will have the first surface 31 of first curvature radius and the second surface 32 and eyeball perfect matching with second curvature radius, to realize initial optical design original intention.
In other embodiment of the present utility model, the shape of bottom coating layer 1, middle part uvea 2 is mated mutually, and structure is compacter, and the conjugation between each layer is more firm.
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.
