Abstract
The utility model discloses color changeable type contact lenses. The lenses comprise a left lens and a right lens, wherein the left lens and the right lens comprise bottom film coating layers, middle pigment layers and top lens layers; an optical area is formed in a central area of each top lens layer, the lower part of the optical area of each top lens layer is covered with each middle pigment layer, the lower part of each middle pigment layer is covered with each bottom film coating layer, and the bottom film coating layers, the middle pigment layers and the top lens layers are combined together closely; the middle pigment layers of the left lens and the right lens are photochromic; and the middle pigment layers present multiple colors when the environmental ultraviolet strength is higher than a predetermined value, and the middle pigment layers are transparent when the environmental ultraviolet strength is lower than the predetermined value. Aiming at the disadvantages of contact lenses in the prior, the utility model provides the color changeable type contact lenses with an ultraviolet protecting effect.
Description
Technical field
The utility model relates to the contact lenses field.
Background technology
Contact lenses (Contact Lens), or contact lens, be a kind of being worn on cornea, in order to correct defects of vision or to protect the eyeglass of eyes.It comprises rigid and soft two kinds, contact lenses are not only from having brought very large improvement to 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, this external control adolescent myopia, astigmatism development, treat the special aspects such as illness in eye and also brought into play special effect.Contact lenses are compared frame eyeglasses many advantages, and contact lenses do not have the obstruction of picture frame, there is no weight, and wearer's outward appearance be there is no to impact, and to the personage who likes to be beautiful, especially the women is very applicable.The obstacle that there is no frame, and the risk that spectacle lenses may be cracked, contact lenses also bring larger convenience for the motion personage.Frame eyeglasses is subject to the restriction of framework, and contact lenses are not subject to anyly to block and limit, thereby contact lenses are broader than the visual field of frame eyeglasses.
But, user for some specific groups, for example eye has the user that other sufferer or some need to be in the special living and working environments of being everlasting, often need to avoid preventing from contacting a large amount of ultraviolet rays or reducing ambient light intensity, often need to prepare again a secondary sunglasses for fear of this situation, often bring unnecessary trouble, if now contact lenses itself just have the ultraviolet protection function, often give the user who relies on accurate visual determination, benefited a great deal.
Summary of the invention
The deficiency existed for contact lenses in prior art, the utility model provides a kind of color variable type contact lenses with ultraviolet protection effect.
For achieving the above object, the technical solution of the utility model provides a kind of color variable type contact lenses, comprise left side eyeglass and right side eyeglass, described left side eyeglass and right side eyeglass are by the bottom coating layer, the middle part uvea, the top layer mirror plate layers forms, the central area of described top layer mirror plate layers is formed with optical region, described middle part uvea is covered in the below of the optical region of described top layer mirror plate layers, described bottom coating layer is covered in uveal below, described middle part, described bottom coating layer, the middle part uvea, the top layer mirror plate layers combines closely, the middle part uvea of described left side eyeglass and right side eyeglass is photochromic, when the environment UV intensity is greater than predetermined value, described middle part uvea presents colored shape, when the environment UV intensity is less than predetermined value, described middle part uvea presents transparence.
As further improvement of the utility model, described middle part uvea at least covers the pupil surface.
As further improvement of the utility model, described middle part uvea presents blueness, grey, purple, pink colour, any in dark brown.
As further improvement of the utility model, described left side eyeglass and right side eyeglass are a kind of in concave lens, polarized lenses and presbyopic lens.
Owing to having adopted above technological means, the utility model, as a kind of novel contact lenses, has facilitated the above Working Life of mentioned special population.
The accompanying drawing explanation
Fig. 1 is the layer structure schematic diagram according to color variable type 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 to more explicit defining.
Shown in accompanying drawing 1, a kind of color variable type contact lenses, comprise left side eyeglass and right side eyeglass, left side eyeglass and right side eyeglass are by bottom coating layer 1, middle part uvea 2, top layer mirror plate layers 3 forms, the central area of top layer mirror plate layers 3 is formed with optical region 31, the middle part uvea 2 be covered in top layer mirror plate layers 3 optical region 31 below and at least cover the pupil surface, bottom coating layer 1 is covered in the below of middle part uvea 2, bottom coating layer 1, middle part uvea 2, top layer mirror plate layers 3 combines closely, the middle part uvea 2 of left side eyeglass and right side eyeglass is photochromic, when the environment UV intensity is greater than predetermined value, middle part uvea 2 presents colored shape, when the environment UV intensity is less than predetermined value, middle part uvea 2 presents transparence.
In certain embodiment of the present utility model, the middle part uvea presents blueness, grey, purple, pink colour, any in dark brown.In addition, left side of the present utility model eyeglass and right side eyeglass can be a kind of in concave lens, polarized lenses and presbyopic lens.
Owing to having adopted above technological means, the utility model, as a kind of novel color variable type contact lenses with ultraviolet protection effect, greatly facilitates the Working Life of above mentioned special population.
Above embodiment is only 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.
