Description
Technical field
The utility model relates to optometric technology field, more particularly to a kind of radiation-proof light-filtering contact lens.
Background technique
Contact lenses are also contact lens, are that one kind is worn on cornea, to correct defects of vision or protect eyes
Eyeglass.According to material it is soft or hard it include rigid, semi-hard, soft three kinds.Contact lenses not only from the appearance with convenience side
Face brings very big improvement to ametropia patients such as myopia, long sight, astigmatism.And the visual field is broad, view object is true to nature, furthermore exists
Adolescent myopia, astigmatism development are controlled, special eye disease etc. is treated and has also played special effect.
It is well known that ultraviolet light can not only kill virus, can also biggish injury will cause to human skin and eyes, such as
Keratitis, the cataract of light radiation initiation；Simultaneously, it is seen that there are the short wavelength components such as purple light and blue light to cause to retina in light
Serious injury, such as treating senile maculopathy.People are easy to happen view in the high luminous environment of ultraviolet light, short wavelength light component ratio
Feel uncomfortable even eye illness.Such as: being easy to happen visual fatigue in fluorescent lamp, screen luminous environment, even cloudy in snowfield, still can
Visual discomfort, the impression such as eyeball shouting pain occurs, or even snow blindness occurs, plateau and long-term outdoor occupational population, in snowfield walking or
Eyes are opened not open when the water surface works, it has to be narrowed eyes, be forced to reduce pupil, cataract incidence is caused to increase；Equally exist
Under strong artificial light sources, people also may feel that eyes have shouting pain uncomfortable, and above-mentioned objective phenomenon all illustrates ultraviolet light and shortwave
Light has biggish injury to our eyes.
Current contact lenses are received by many people, and contact lens can achieve light, beautiful, fashion, correction
The indeformable effect of eyesight, but it is all the material composition for being unable to filtering ultraviolet light and short wavelength light, and the ultraviolet light of contact lenses is anti-
It is not high to protect performance, with less the light-operated performance of purple light, blue light, if to reach i.e. preventing ultraviolet can filter out shortwave harmful light again
Purpose, it is also necessary to separately wear other functional glasses, such as sunglasses, be in this way cumbersome also unsightly, it is more important
Be that sunglasses reduces that light is well-illuminated, and things is unclear under dark situation, lose the meaning of contact lens.
Therefore, the problem of how a kind of radiation-proof light-filtering contact lens are provided, is those skilled in the art's urgent need to resolve.
Utility model content
In view of this, the present invention provides a kind of radiation-proof light-filtering contact lens, energy filtering ultraviolet light, and can control
Filter out some blue light (i.e. wavelength be 380-450nm shortwave light) component, can effectively defend the photochemistry of light radiation to injure,
Better visual quality can be obtained simultaneously, makes people compared with low light environment and compared with can clearly regard object in strong light environment.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of radiation-proof light-filtering contact lens, including being attached to eyeball surface and the soft lens body identical with eyeball curved surface,
It is characterized in that, the lens body includes the central optical zone and peripheral region of arranged concentric；
The side that the lens body is bonded with eyeball has a hydrophilic layer；
The central optical zone is equipped with yellow radiation-proof light-filtering dye coatings, and the yellow radiation-proof light-filtering dye coatings are set
It sets between the lens body and the hydrophilic layer；
The peripheral region is located at the outside of the central optical zone.
Further, diameter of a circle D1 where the cambered surface of the lens body is 13.9-14.0mm.
Further, diameter of a circle D2 where the cambered surface in the optics area is 7-8mm.
Further, diameter of a circle where the cambered surface of the yellow radiation-proof light-filtering dye coatings is 7-8mm.
Further, the yellow radiation-proof light-filtering dye coatings with a thickness of 0.003-0.005mm.
It can be seen via above technical scheme that compared with prior art, the utility model effectively can keep out and filter purple
Outside line, and effectively control by the radiation-proof light-filtering coating of yellow filter out some blue light (i.e. wavelength for 380-450nm shortwave
Visible light) component, greatly improve the use effect of contact lenses under strong light.
