wherein the first near vision diopter area is hexagonal; the second defocus diopter area is densely distributed with a plurality of independent diopter units, and the diopter units have different diopters.
According to an embodiment of the present invention, the dioptric unit is configured in a circular shape with a diameter of 0.01mm to 0.15mm, and the surface has a protrusion or a depression with a height of 0.01 μm to 4 μm.
According to an embodiment of the invention, the dioptric unit has a positive power added to the first near vision power zone or a negative power added to the first near vision power zone.
According to an embodiment of the present invention, the first near vision power zone and the third peripheral power zone have the same power.
According to an embodiment of the present invention, the first near vision power zone and the third peripheral power zone have different powers.
According to an embodiment of the present invention, the width of the first near vision diopter area is 1.5mm-2.2 mm.
According to an embodiment of the present invention, the second defocus area is hexagonal.
Compared with the prior art, the invention can obtain the following technical effects:
set up hexagonal first myopia diopter district through the center at contact lens, satisfy the center and use the eye demand, and peripheral second out of focus diopter district then sets up a plurality of refraction units for realize the positive negative increase of diopter, guarantee that the user sees with the visual area demand of controlling, realize out of focus and change, avoid teenagers to use the eye discomfort, deepen the number of degrees, reinforcing myopia prevention and control.
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.

In the drawings:
FIG. 1 is a schematic view of an out-of-focus contact lens for controlling myopia according to an embodiment of the present invention.
Reference numerals
The contact lens comprises a contact lens body 10, a first near vision diopter area 11, a second out-of-focus diopter area 12, a third peripheral diopter area 13 and a dioptric unit 20.
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, fig. 1 is a schematic view of an out-of-focus contact lens for controlling myopia according to an embodiment of the present invention.
As shown, an out-of-focus contact lens for controlling myopia, comprising: the contact lens comprises a contact lens body 10, wherein the contact lens body 10 is provided with a first near vision diopter area 11 positioned in the center, a second out-of-focus diopter area 12 annularly arranged in the first near vision diopter area 11, and a third peripheral diopter area 13 arranged around the second out-of-focus diopter area 12; wherein the first near vision diopter area 11 is hexagonal; the second defocus area 12 is densely distributed with a plurality of individual dioptric units 20, and the dioptric units 20 are different in diopter.
In one embodiment of the invention, the contact lens body 10 is made of polyhydroxyethylmethacrylate and has, from the inside out, a first near vision power zone 11, a second defocus power zone 12, and a third peripheral power zone 13 in the center. Wherein, first myopia diopter district 11 sets up to the hexagon district at contact lens body 10 center for aim at user's eyes central authorities, normal head when realizing that the user wears is looked squarely, realizes central focusing, when satisfying the eye demand for the center, farther sight demand about can realizing, guarantees the comfort level of eye, avoids deepening the degree. The second out-of-focus diopter area 12 is densely distributed with a plurality of independent diopter units 20, diopter of the second out-of-focus diopter areas changes compared with the first out-of-focus diopter area 11, when the user looks at the upper and lower sides or the left and right sides far away, because eyeballs and visual distances change, in order to protect eyes, eyestrain is avoided, the visual area is set as the second out-of-focus diopter area 12 with diopter change, the first out-of-focus diopter area 11 is surrounded in distribution, and the corresponding setting of the user interpupillary distance can be realized.
