The invention is described in further detail below with reference to the following figures and detailed description:
the spectacle lens with a defocused periphery of the microlens is a spectacle lens with a frame, and is hereinafter referred to as such a spectacle lens.
The spectacle lens is provided with a central correction area, a nasal side micro lens area, a temporal side micro lens area and a lower side micro lens area, wherein the nasal side micro lens area and the temporal side micro lens area are respectively provided with two gradual change micro lens areas and a full micro lens area with different refractive powers.
Alternatively, the lens is provided with a central correction region, an annular microlens region provided with two gradation annular microlens regions and a total annular microlens region having different refractive powers, or an annular lower microlens region in the lower region of the annular microlens region.
The micro lens area is composed of a plurality of micro lens arrays independent of each other, and at least two or more micro lenses in the micro lens array area are different in refractive power, shape and radial line length. The independent micro lens is arranged to be a convex lens relative to the central correction area, the radial line length is 0.2mm to 4.5mm, and the distance between every two adjacent micro lenses is 0.1mm to 0.4 mm.
Or the independent micro-lens is arranged in a nanometer scale, and the radial line length is 10nm to 100 nm.

The main pathogenic mechanism of myopia is peripheral hyperopic defocus of retina, and the recent research proves that: the myopic eye is mainly caused by hyperopic defocus of the periphery of the temporal retina, or the hyperopic anisometropia of the periphery of the nasal temporal retina. Along with the increase of the myopia degree, the hyperopic refractive power difference value at the periphery of the nasal temporal retina correspondingly increases, and the nasal temporal retina periphery asymmetric hyperopic refractive power difference of the myopic eye is corrected, so that the nasal temporal retina periphery asymmetric hyperopic refractive power difference correction method is a first-choice intervention measure for correcting and controlling the myopia degree increase.
The peripheral out-of-focus spectacle lens popular in the market at present comprises a Zeiss Changle spectacle lens with an elliptic central visual area, and the authorization notice number is CN 101855590B; the central visual area is a perfect circular ring focus spectacle lens, and the authorization notice number is CN 101317120B; a novel Haoya micro-lens ring focus spectacle lens has an authorization notice number CN 104678572B. The existing peripheral defocus spectacle lens can not correct the asymmetric hyperopic defocus on the nasal temporal side, so that one side is over-corrected and one side is under-corrected, and new peripheral hyperopic refractive error is generated.
The peripheral out-of-focus spectacle lens of the micro lens is designed into a nose side micro lens area and a temporal side micro lens area, and aims to correct hyperopic refractive error at the periphery of retina and correct myopic eye adjustment and convergence dysfunction by designing a lower side micro lens area.
The microlens area of the spectacle lens is composed of a plurality of independent microlens arrays, and at least two or more microlens arrays in the microlens array area have different refractive powers, shapes and meridian length settings. The micro-lens array area is designed with two or more micro-lenses with different refractive powers, so as to reduce the phenomenon of refractive jump caused by too fast transition of the refractive powers at two adjacent positions.
The periphery of the lower side retina on the upper side of the myopic eye presents myopic defocusing, and the myopic defocusing is good defocusing for the myopic eye, so that the growth of eyeballs is delayed, and the increase of myopic degrees is controlled. The periphery of the lower side retina of the upper side of the myopia presents myopic defocus, and the myopia is not induced and does not need to be corrected. The central correction area of the spectacle lens is designed into an up-and-down windowing type, the length of a horizontal radial line along the half side of the optical center is 4mm to 8mm, and the diopter power set in the central correction area is 0.00D to-8.00D. The optical center diameter of the spectacle lens is 5mm, the refractive error within 10 degrees of a macular area of the retina is corrected, the myopic eye presents central myopic defocusing of the retina, the concave lens is used for enabling light rays to shift backwards, the focus falls on the retina, the central correction area is designed to be too narrow, the visual field is limited, the central correction area is designed to be too wide, and the peripheral defocusing correction area is relatively too narrow.
The nasal side micro-lens area or the temporal side micro-lens area is set to be two gradual change micro-lens areas and a full micro-lens area with different refractive powers, the distance between the gradual change micro-lens areas and an optical center is 4mm to 8mm, and the length of a horizontal radial line is 4mm to 6 mm. The horizontal diameter length of the total micro-lens area is 8mm to 16mm or is arranged to the edge of the spectacle lens, and at least the total micro-lens area is arranged at a position 20mm away from the optical center. The total number of zones of the microlenses is arranged at least 20mm from the optical centre, in order to ensure that the spectacle lens has an adequate correction for the peripheral hyperopic defocus zone of the retina. The myopic eye presents hyperopic defocus at the peripheries of the nose and the temporalis of the retina, the temporalis is larger than the hyperopic defocus at the peripheries of the nose of the retina, and the defocus is larger when the hyperopic defocus at the peripheries of the retina is closer to the periphery. The peripheral retina is 30 ° to 40 ° as a correction for peripheral retinal hyperopic defocus, measured using a peripheral retina refractometer. The light rays are shifted forward using positive addition of power to the central correction zone using a convex lens, with the focus falling on the retina.
The nasal side micro-lens area or the temporal side micro-lens area is set to be a gradual change micro-lens area and a full micro-lens area, so that the refractive power of the central correction area and the full micro-lens area is uniformly transited by the gradual change micro-lens area, and the refractive jump phenomenon is reduced. Another object of the spectacle lens provided with the progressive microlens region and the full microlens region is to gradually increase the refractive power of the spectacle lens from the inside to the outside as the distance of the hyperopic defocus in the periphery of the retina is larger in the vicinity of the peripheral portion. The progressive lenticule area gradually increases in a gradient from +0.25D to +0.75D to a full lenticule area power, preferably a gradient of +0.50D, depending on the central correction area power, the full lenticule area power being greater than the progressive lenticule area power.
The refractive power of the nasal micro-lens area is larger than that of the temporal micro-lens area, so that the peripheral hyperopic defocus of the temporal retina of the myopic eye is corrected to be larger than that of the nasal peripheral hyperopic defocus, and the peripheral hyperopic defocus of the nasal and temporal retina is corrected to be above the retina uniformly.
The lower microlens region is disposed in a positive addition to the central correction region refractive power, or disposed with the composite substrate facing the nasal prism. The nasal and temporal microlens areas are arranged to have a power +0.50D to +5.00D greater than the power +0.50D to +2.00D of the temporal microlens area relative to the central correction area power.
The spectacle lens has the same or different numbers of microlenses in the nasal side microlens area and the temporal side microlens area, at least more than 80 independent microlenses are arranged on each side, and the independent microlenses are arranged in a perfect circle shape, an ellipse shape or a hexagon shape. The independent microlens radial line length sets up millimeter level, micron level and nanometer level, and millimeter level sets up the radial line length and is 0.8mm to 2.0mm, and two adjacent microlens intervals are 0.1mm to 0.2mm, and micron level sets up radial line length and is 300 mu m to 700 mu m, and nanometer level sets up radial line length 10nm to 100 nm.

The other technical scheme of the peripheral out-of-focus spectacle lens of the micro lens is as follows: the lens surface is designed into a central correction area for correcting the central myopic defocus of the retina of the myopic eye and an annular micro-lens area for correcting the peripheral hyperopic defocus of the retina of the myopic eye.
