Abstract
The invention discloses a contact lens. The contact lens comprises a lens layer. A loop of hydrophilic layer is arranged around the inner side of the lens layer. A plurality of channels are arranged in one side, fitting an eyeball, of the hydrophilic layer uniformly. The plurality of channels are arranged in a radial manner. The plurality of channels are recessed grooves arranged in the inner surface of the hydrophilic layer, and extend from the inner side of the hydrophilic layer to the outer side. The hydrophilic layer is arranged under the lens layer, the hydrophilic layer has an annular structure, and the channels are arranged to connect an eyeball under the lens layer and the eyeball at the outer side of the lens layer. The contact lens has good breathability. The pressure of the lens layer to an eyeball is reduced because of support of the hydrophilic layer, and wearing is comfortable.
Description
Technical field
The present invention relates to optometric technology field, particularly a kind of contact lens.
Background technology
Contact lenses, are also contact lens, are that one is worn on cornea, in order to correct defects of vision or to protect the eyeglass of eyes.According to the soft or hard of material, it comprises rigid, semi-hard, soft three kinds.Contact lenses are not only from bringing very large improvement to 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 develop, and treat the aspects such as special illness in eye and have also played special effect.Hospital expert reminds contact lens need to regular hospital or join illuminating apparatus structure and do detailed inspection, select the contact lenses being applicable to oneself wearing, and note eye health, avoid causing other eye symptoms, if it is uncomfortable to wear rear discovery, check to hospital in time.
Generally, the permeability of contact lenses causes eye anoxic to cause FAQs that is red and swollen and disease.Contact lenses due to directly and eyeball fit, make eyeball ventilative not, the symptom such as easily cause anoxic dry and astringent.
Summary of the invention
The technical issues that need to address of the present invention are existing contact lenses due to directly and eyeball fit, make eyeball ventilative not, the symptom such as easily cause anoxic dry and astringent.
For solving the problems of the technologies described above, the invention provides a kind of contact lens, comprise mirror plate layers, the inside circumference of described mirror plate layers is provided with a circle hydrophilic layer, many passages are evenly provided with in described hydrophilic layer and eyeball side of fitting, and many passage radially arranges, many passages are be arranged on the groove on hydrophilic layer inside surface, extend to outer side edges from the inner side edge of hydrophilic layer.Contact lens of the present invention, arranges hydrophilic layer below mirror plate layers, and hydrophilic layer structure is ring-type, and eyeball outside eyeball and mirror plate layers is set below expanding channels mirror plate layers, more ventilative, and due to the support of hydrophilic layer, mirror plate layers reduces the pressure of eyeball, wears more comfortable.
As the preferred technical solution of the present invention, the thickness of described hydrophilic layer is diminished gradually by Inside To Outside, is camber line transition from thick to thin inside described hydrophilic layer with mirror plate layers junction.The thickness of hydrophilic layer and radian are arranged, and all make hydrophilic layer more to fit eyeball.
Wherein, described hydrophilic layer is hydrophilic polymer.The hydrophilic polymer that hydrophilic layer selects water cut higher, when avoiding wearing, eyeball is dry and astringent, and the higher hydrophilic polymer of water cut is comparatively soft, can avoid the injury to eyeball.
As a further improvement on the present invention, between described mirror plate layers and hydrophilic layer, be also provided with color layer, described color layer is that upper and lower two-layer coating layer tundish covers coloured dye, and the area of described color layer is less than the area of hydrophilic layer and is covered by hydrophilic layer.Between mirror plate layers and hydrophilic layer, be provided with color layer, and color layer is covered by hydrophilic layer, the color of contact lenses can be increased like this, contact lenses comfortableness originally can not be changed again, and for preventing the spilling of coloured dye from being also many one deck protection.
Contact lens of the present invention, arrange hydrophilic layer directly to fit eyeball, mirror plate layers frame is gone out some spaces, and by eyeball outside radiation expanding channels mirror plate layers gaps underneath that hydrophilic layer is arranged and mirror plate layers, be conducive to oxygen conduction and the tear conduction of eyeball below mirror plate layers, make contact lens comfortable wearing, not easily dry and astringent.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is right view of the present invention;
Wherein, 1-mirror plate layers, 2-hydrophilic layer, 3-passage, 4-color layer.
Embodiment
The preferred technical solution of the present invention is described in detail below in conjunction with accompanying drawing.
As shown in the figure, contact lens of the present invention, comprise mirror plate layers 1, the inside circumference of described mirror plate layers 1 is provided with a circle hydrophilic layer 2, many passages 3 are evenly provided with in described hydrophilic layer 2 and eyeball side of fitting, and many passage 3 radially arranges, many passages 3 are for being arranged on the groove on hydrophilic layer 2 inside surface, outer side edges is extended to from the inner side edge of hydrophilic layer 2, the thickness of described hydrophilic layer 2 is diminished gradually by Inside To Outside, is camber line transition from thick to thin with mirror plate layers 1 junction inside described hydrophilic layer 2.Wherein, described hydrophilic layer 2 is hydrophilic polymer, between described mirror plate layers 1 and hydrophilic layer 2, be also provided with color layer 4, described color layer 4 covers coloured dye for upper and lower two-layer coating layer tundish, and the area of described color layer 4 is less than the area of hydrophilic layer 2 and is covered by hydrophilic layer 2.
Contact lens of the present invention, arranges hydrophilic layer below mirror plate layers, and hydrophilic layer structure is ring-type, and eyeball outside eyeball and mirror plate layers is set below expanding channels mirror plate layers, more ventilative, and due to the support of hydrophilic layer, mirror plate layers reduces the pressure of eyeball, wears more comfortable.
The thickness of hydrophilic layer and radian are arranged, and all make hydrophilic layer more to fit eyeball.And after hydrophilic layer is set, the material range of choice of mirror plate layers is a little just more extensive, and but hardness can be selected higher a little shaping good material, the conservation degree of such eyeglass can be relatively good, owing to there is the support of hydrophilic layer, the impact of hardness on eyeball of mirror plate layers weakens greatly.
The hydrophilic polymer that hydrophilic layer selects water cut higher, when avoiding wearing, eyeball is dry and astringent, and the higher hydrophilic polymer of water cut is comparatively soft, can avoid the injury to eyeball.
Between mirror plate layers and hydrophilic layer, be provided with color layer, and color layer is covered by hydrophilic layer, the color of contact lenses can be increased like this, contact lenses comfortableness originally can not be changed again, and for preventing the spilling of coloured dye from being also many one deck protection.
Contact lens of the present invention, arrange hydrophilic layer directly to fit eyeball, mirror plate layers frame is gone out some spaces, and by eyeball outside radiation expanding channels mirror plate layers gaps underneath that hydrophilic layer is arranged and mirror plate layers, be conducive to oxygen conduction and the tear conduction of eyeball below mirror plate layers, make contact lens comfortable wearing, not easily dry and astringent.
