In order to solve the above technical problems, the present invention discloses an anti-fatigue contact lens, comprising:
the contact lens comprises a contact lens body, wherein the contact lens body is provided with a central visual area which is positioned in the center and is circular, and an annular visual area which is annularly arranged on the central visual area, and the central visual area is provided with an upper visual area and a lower visual area.
According to an embodiment of the present invention, the diameter of the central viewing area is 9 mm; the outer diameter of the annular visual area is 14 mm.
According to an embodiment of the present invention, the upper viewing area occupies 3/5, and the lower viewing area occupies 2/5.
The invention also discloses a balancing method processing technology for processing the anti-fatigue contact lens, which comprises the following steps:
step one, taking a contact lens body formed by injection molding, and detecting the thickness of the contact lens body;
step two, the measured contact lens body is sent into a positioning device, the positioning device performs positioning through a balancing method, and a shaft position origin point on a peripheral visual area is found out;
thirdly, cutting a cutter of the cutting device into the original point of the axial position, and adjusting the cutting depth according to the thickness of the contact lens body;
and step four, rotating the positioning device at a constant speed, and cutting the surface radians of the annular visual area and the central visual area by the cutter.
Compared with the prior art, the invention can obtain the following technical effects:
through setting up the central vision area and the annular visual area of different radians, improve the grading, the central vision area divide into upper and lower visual area simultaneously, improves and wears the travelling comfort, protects eyes.
Of course, it is not necessary for any one product in which the invention is practiced to achieve all of the above-described technical effects simultaneously.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings and examples, so that how to implement the technical means for solving the technical problems and achieving the technical effects of the present invention can be fully understood and implemented.
Referring to fig. 1 and 2 together, fig. 1 is a schematic cross-sectional view of an anti-fatigue contact lens according to an embodiment of the invention; fig. 2 is a top view of a fatigue resistant contact lens according to an embodiment of the invention.
As shown, an anti-fatigue contact lens, comprising: the contact lens comprises a contact lens body 10, a lens body and a lens, wherein the contact lens body is provided with a central visual area 11 which is positioned in the center and is circular, and an annular visual area 12 which is annularly arranged on the central visual area 11; wherein, the annular visual area 12 has a progressive refraction band, and the outer surface of the annular visual area 12 has a surface radian different from that of the central visual area 11. The central visual area 11 is provided with an upper visual area and a lower visual area, so that the user can see far and near conveniently, and the wearing comfort is improved.
In one embodiment of the present invention, the contact lens body 10 is divided into a central viewing zone 11 and an annular viewing zone 12 from the inside to the outside. Wherein the central visual zone 11 is aligned with the center of the eye and horizontally divided into an upper visual zone and a lower visual zone, which serve as a main visual zone. The transition is established to annular visual area 12 ring for focusing eye, the sight that adapts to different distances is observed, improves the travelling comfort of wearing, strengthens the travelling comfort of wearing simultaneously.
In a preferred embodiment, the central viewing zone is 9mm in diameter; the outer diameter of the annular visual area is 14 mm.
Further, the upper viewing zone area occupies 3/5 and the lower viewing zone area occupies 2/5.
The invention also discloses a balancing method processing technology for processing the anti-fatigue contact lens, which comprises the following steps:
step one, taking a contact lens body formed by injection molding, and detecting the thickness of the contact lens body;
step two, the measured contact lens body is sent into a positioning device, the positioning device performs positioning through a balancing method, and a shaft position origin point on a peripheral visual area is found out;
thirdly, cutting a cutter of the cutting device into the original point of the axial position, and adjusting the cutting depth according to the thickness of the contact lens body;
and step four, rotating the positioning device at a constant speed, and cutting the surface radians of the annular visual area and the central visual area by the cutter.
In conclusion, the central visual area and the annular visual area with different radians are arranged, so that light distribution is improved, meanwhile, the central visual area is divided into the upper visual area and the lower visual area, the wearing comfort is improved, and eyes are protected.
The foregoing description shows and describes several preferred embodiments of the invention, but as aforementioned, it is to be understood that the invention is not limited to the forms disclosed herein, and is not to be construed as excluding other embodiments, and that the invention is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art.
