Description
Technical Field
The invention belongs to the technical field of optical lenses, and particularly relates to a resin lens with progressive refractive power.
Background
From the current market feedback, frame glasses are also the main correction mode and the mode for controlling the myopia development of most myopia groups. The main method is progressive multi-focus frame glasses, and the progressive multi-focus lens realizes the addition of near positive power through the power change on the central sight channel of the lens. It is characterized by that on the lens the myopia number can be gradually reduced from upper portion to lower portion, so that when the wearer is looking at far distance, the wearer can adopt different numbers of myopia, and can attain the goal of relaxing and regulating. The peripheral defocus frame glasses slow down the elongation of the eye axis by reducing the principle of retina peripheral hyperopia defocus. With normal frame glasses (single vision lenses) there is a hyperopic defocus around the retina, i.e. the peripheral focus falls behind the retina. The out-of-focus lens can change the far-vision out-of-focus at the periphery of the retina into the near-vision out-of-focus, thereby inhibiting the increase of the axis of the eye to achieve the purpose of controlling the power. However, because the peripheral defocus in the peripheral out-of-focus frame glasses acts on the eyeball, there is some correlation between eyeball motion and myopia control effects.
Therefore, a new type of myopia prevention and control progressive lens which is comfortable to wear and guarantees eyesight needs to be researched.

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 diagram of a progressive-power resin lens according to an embodiment of the present invention.
As shown in the drawing, a progressive-power resin lens includes: the lens comprises a lens body 10, wherein the lens body 10 is provided with a first power area 11 positioned in the center, a second power area 12 annularly arranged on the first power area 11, and a third power area 13 annularly arranged on the second power area 12; the first power zone 11 is provided with a left upper arc angle zone 21, a right upper arc angle zone 22 and a lower arc angle zone 23 which extend outwards from the center, the left upper arc angle zone 21 is symmetrical about a left upper ray, the right upper arc angle zone 22 is symmetrical about a right upper ray, the lower arc angle zone 23 is symmetrical about a lower ray, the left upper ray, the right upper ray and the lower ray all penetrate through the center, and adjacent included angles are all 120 degrees; the outer edges of the second power zone and the third power zone are rounded.
In one embodiment of the present invention, the lens body 10 is formed by resin curing, and has a first power zone 11, a second power zone 12, and a third power zone 13 sequentially arranged from inside to outside. The first power zone 11 is trilobal, and has a left upper arc angle zone 21, a right upper arc angle zone 22 and a lower arc angle zone 23 extending outwards from the center, which are respectively in a round angle shape, and are symmetrical with respect to the respective upper left light, upper right light and lower light, adjacent included angles are 120 degrees, and are evenly divided, so that the requirement of eyes on the upper two angle extending positions and the lower one angle extending position of the center of the lens can be met. In short, when the user is wearing glasses, when the user needs to look at the upper left and right sides of the central sight line, or look down, because of the habit of the human body, at this moment, for some smaller deflection angles, the human body can not deflect the head, only can rotate the eyeball, at this moment, the first diopter region 11 can perfectly and fully cover the sight line range, and the eyes are prevented from being converted to the second diopter region, so that the focus is converted, and the trouble of eye fatigue is avoided, and the degree can be increased seriously.

The diopter of the first diopter area 11 is changed compared with the diopter of the second diopter area, and when the user looks upward or far from the left and right sides, the eyeball and the visual range are changed, so that the eye fatigue is avoided for protecting the eyes. Preferably, the dioptric unit is configured in a circular shape of 0.1mm-1.5mm and the surface is convex or concave, the height of the convex or concave being 0.01 μm-4 μm. Further, when the dioptric unit is convex or concave, the diopter unit has the diopter which is increased by positive power relative to the first diopter area 21 or has the diopter which is increased by negative power relative to the first diopter area 11, so that diopter change is completed, the diopter unit is adaptive to visual range, defocus change is completed, and eye comfort is guaranteed.
In summary, the first power zone with three arc angle zones is arranged on the lens body, so that the requirements of a user for seeing the center, seeing down and seeing the left and right visual zones are met, and the eye comfort level is improved; and the peripheral second diopter area is provided with a plurality of diopter units for realizing diopter positive and negative increase, ensuring the visual area requirements of users on seeing and on the left and right, realizing defocusing conversion, avoiding the discomfort of teenagers with eyes and degree deepening, and enhancing myopia prevention and control.
