[0014] The peripheral defocus spectacle lens with microlenses has a large refractive power of a convex lens, but the microlenses cannot achieve individualized differential customization, especially with an accuracy of 0.01 diopter.

[0015] For the existing refractive and microlens peripheral defocus spectacle lenses, the positive addition value is formed on one lens surface.

[0016] In his latest research paper, Smith critically pointed out that there were design flaws in his original design of the treatment area in the 360° peripheral region of the lens, and proposed that the peripheral hyperopic defocus of the retina that induces eye growth is a local, regionally selective mechanism (Local, Regionally Selective Mechanisms). The temporal retina dominates eye growth, and the nasal-temporal peripheral defocus shows asymmetry. Circular correction cannot eliminate peripheral anisometropia and generates new peripheral hyperopic anisometropia (hyperopicanisometropi). See the literature: Smith EL: Optom Vis Sci, 2013, 90: 1176 - 1186; Smith EL: Invest Ophthalmol Vis Sci, 2010, 51: 3864 - 3873; Smith EL: Invest Ophthalmol, VisSci, 2009, Nov; 50(11): 5057 - 5069. Smith elaborated on the peripheral refractive power detection of the retina of 1155 myopic eyes with -2.27D ± 0.83D in WO2012 / 012826A1 and WO2013 / 134825A1, showing that the peripheral refractive power in the 40° temporal side is +0.83D greater than that in the nasal side.

[0017] The applicant's detection of the peripheral refractive power of 1809 myopic eyes found that: the greater the degree of myopia, the greater the peripheral hyperopic defocus of the retina in the 40° temporal side, and the greater the value of the peripheral hyperopic refractive anisometropia between the nasal and temporal retinas. The maximum refractive anisometropia value of some cases is greater than +1.25D.

[0018] Regardless of whether it is a refractive or microlens peripheral defocus spectacle lens, using an equal positive addition value in the peripheral treatment area cannot correct the peripheral hyperopic refractive anisometropia of the nasal and temporal retinas. Correcting the peripheral refractive anisometropia of the nasal and temporal retinas is more scientifically significant for the prevention and control of myopia.

[0019] New surface innovation designs for peripheral defocus spectacle lenses are yet to be developed, and the myopic peripheral defocus spectacle lens remains one of the technical problems in the spectacle field. Summary of the Invention

[0052] The double-mirror double-positive addition individualized defocus spectacle lens is a frame spectacle lens, hereinafter referred to as such a spectacle lens. The central area of the front mirror surface of the spectacle lens is a plano lens or a concave lens. The central area of the rear mirror surface is a refractive lens with a power of 0.00D to -10.00D to meet the needs of different myopic wearers. For those with astigmatism, astigmatism degrees and axes of < -4.00DS can be compounded. The central areas of the front and rear mirror surfaces are compounded into a central correction area. The peripheral area of the front mirror surface consists of multiple independent micro-lenses, and the refractive power of the micro-lenses is set to a base positive addition value of +0.50D to +4.00D to meet the positive addition needs of different myopic degrees. The refractive power of the peripheral area of the rear mirror surface is a refractive lens with a differential positive addition value of +0.50D to +3.00D compounded with the concave lens refractive power of the central correction area. The refractive power of the peripheral area of the rear mirror surface is added with a differential positive addition value on the basis of the myopic degree. The double positive addition values of the peripheral areas of the front and rear mirror surfaces are compounded into a total positive addition value of +1.00D to +7.00D for the individualized peripheral treatment area. The individualized refractive power gradient difference of the differential positive addition value or the total positive addition value is ±0.05D to ±0.25D, and the refractive power gradient difference is set for individualized differential spectacle wearers. The differential positive addition value of the rear mirror surface adopts a laboratory-molded technology, and the refractive power can be accurate to 0.01D, so as to achieve individualized selection.

[0053] Full-ring equal positive additions are set in the peripheral areas of the front and rear mirror surfaces, or the nasal peripheral area and the temporal peripheral area are set, and the positive addition value of the nasal peripheral area > the temporal peripheral area, aiming to conform to the defocus of the temporal peripheral retina of myopia being greater than that of the nasal peripheral retina. At least 5 positive addition gradient sections and 5 total positive addition sub-levels are set in the peripheral area, where: Base positive addition value + differential positive addition value = total positive addition value of the individualized peripheral treatment area; The base positive addition value is 95% to 5% of the total positive addition value of the individualized peripheral treatment area; The differential positive addition value is 5% to 95% of the total positive addition value of the individualized peripheral treatment area; The refractive power of the peripheral area of the front mirror surface = base positive addition value; The refractive power of the peripheral area of the rear mirror surface = concave lens refractive power of the central correction area + differential positive addition value; The positive addition value of the nasal peripheral area is greater than that of the temporal peripheral area by +0.50D to +2.00D.

[0054] The central areas of the front and rear mirror surfaces are set to be circular, elliptical, or vertical diameter windowed according to the shape of the peripheral area. The central area is vertical diameter windowed, with a horizontal diameter length of 7mm to 14mm along the optical center and a vertical diameter equal to the diameter of the spectacle lens. The concave lens refractive power of the central correction area is customized according to the subjective refraction degree. The lower area of the central area is set to be compounded with a prism lens with a base towards the nasal side and a prism power of 0.5△ to 6.0△, or a prism lens with a base towards the lower side and a prism power of 0.25△ to 1.50△.

[0055] The full annular shape of the peripheral area of the front mirror means that the microlens array is within the 360 0 circumferential azimuth angle. The semi-annular shape of the peripheral area of the front mirror means that the microlens array occupies 180 0 circumferential azimuth angle respectively in the nasal peripheral area and the temporal peripheral area. The fan-shaped annular shape of the peripheral area of the front mirror means that in the nasal peripheral area and the temporal peripheral area of the front mirror, the inner arc is < 180 0 circumferential azimuth angle and the outer arc is ≤ 180 0 circumferential azimuth angle. Or, the microlens array in the nasal peripheral area and the temporal peripheral area of the front mirror is set as a perfect circle, a vertical ellipse, a horizontal ellipse, an arc-top shape, or the array forms an irregular shape. The peripheral area of the rear mirror is set as a full annular shape, or the peripheral area is divided into two areas, namely the nasal peripheral area and the temporal peripheral area, and is set as a perfect circle. There is a 2mm to 4mm gradient area between the central area and the peripheral area, and the gradient area integrates the central area and the peripheral area to reduce the refractive power jump phenomenon. Or the full annular shape or the perfect circular nasal peripheral area and temporal peripheral area of the front mirror are composed of a gradient area of microlenses around the convex lens refractive lens.

[0056] The peripheral area of the front mirror can be set as 4 quadrant areas, namely the upper quadrant area, the lower quadrant area, the nasal quadrant area, and the temporal quadrant area. Each quadrant area occupies 90 0 circumferential azimuth angle. The 4 quadrant areas are respectively microlens arrays, or the nasal quadrant area and the temporal quadrant area are microlens sheets, and the upper quadrant area and the lower quadrant area are refractive lenses. The nasal quadrant area is greater than the temporal quadrant area by a positive addition value, and the lower quadrant area is greater than the upper quadrant area by a positive addition value.

[0057] The peripheral area of the front mirror consists of multiple independent microlens arrays, and the microlenses are any one of the shapes of a cylinder, a square, a pentagon, a hexagon, and a rectangle. The diameter or the radial line length of the microlens is in millimeters, micrometers, or nanometers, and is set with a diameter of 2.0mm to 5nm and a height of 16µm to 0.1nm. At least five positive addition value gradient sections are set in the peripheral areas of the front and rear mirrors. The area from the edge of the central area to 10mm to 11.9mm away from the optical center is 20% of the total positive addition value, the area from 12mm to 13.9mm away from the center is 40% of the total positive addition value, the area from 14mm to 15.9mm away from the center is 60% of the total positive addition value, the area from 16mm to 17.9mm away from the center is 80% of the total positive addition value, the area from 18mm to 30mm away from the center is 100% of the total positive addition value, and a concave lens sheet or a plano lens with the same refractive power as the central correction area is set from 30mm away from the center to the edge of the spectacle lens. The purpose of setting five positive addition value gradient sections is consistent with the fact that the hyperopic defocus degree of the peripheral retina of myopia gradually increases from the center to the periphery, and it is more in line with the peripheral defocus theory of the retina.

[0058] The microlenses are preferably set to have a diameter of 1.0mm to 20µm and a height of 10µm to 10nm. From the edge of the central area, 8 to 120 rings are set between 20mm and 30mm from the optical center, and 300 to 8000 independent microlenses are densely distributed. The peripheral areas of the front and rear mirror surfaces are set to full positive value at least 20mm to 28mm from the optical center to correct the hyperopic defocus of the retinal periphery.

[0059] The positive value of the front mirror base is 50% to 70% of the total positive value of the individual peripheral treatment area, and the positive value is +1.00D to +4.00D, with the purpose of effectively correcting the hyperopic defocus. The positive value of the rear mirror difference is 40% to 20% of the total positive value of the individual peripheral treatment area, and the positive value is +0.50D to +2.00D, with the purpose of effectively correcting the individual difference correction. The total positive value of the treatment area is +1.00D to +6.00D, with the purpose of adapting to the positive value of different myopia degrees, correcting the hyperopic defocus state of the myopic retinal periphery to the position above the retina, or correcting it to the front of the retina to form peripheral myopic defocus.

[0060] Differential plus or total plus, based on individual wearer's nasal and temporal 40 0 Retinal peripheral refraction detection hyperopic defocus degree base, nasal side and temporal side add +0.50D to +2.50D positive value respectively. Alternatively, add positive value according to the myopia-inducing factors of individual glasses wearers: parents with high myopia ≥ -6.00D, myopia onset age earlier than 6 years old, myopia degree increase > -0.75D per year, axial length or retinal peripheral refraction increase per year, daily near-distance eye use time ≥ 8 hours, add +0.10D to +0.50D for each inducing factor, and add individual difference positive value of +0.50D to +2.50D. According to the degree of myopia, the total positive addition of the front and back mirror peripheral areas is set to at least 5 total positive addition sub-values: +1.00D, +2.00D, +3.00D, +4.00D, +5.00D, or set to: +1.50D, +2.50D, +3.50D, +4.50D, +5.50D, or 50% of the total positive addition is evenly divided into the front mirror peripheral area and the back mirror peripheral area. The individual refractive power gradient difference of the nasal peripheral area is preferably selected from ±0.05D to ±0.15D, with a total positive addition of +0.50D to +1.50D, a differential positive addition, or a total positive addition greater than that of the temporal peripheral area.

[0061] This type of lens can be set as a near lens and a far lens. The near defocus lens is larger than the far defocus lens with a positive value of +0.50D to +2.00D, or an additional lens with a total positive value of +1.00D to +5.00D can be set. When using the eyes at close range, the additional glasses frame can be clamped on the ordinary glasses frame.

[0062] The microlenses are set at the micron level, with a diameter ranging from 700 µm to 100 µm and a height ranging from 10 µm to 1 µm. The microlenses are set on the front mirror surface, the rear mirror surface or embedded in the spectacle lens matrix, and are composed of one, two, three or four layers. The thickness of the composite layer or coating layer is ≥ the height of the microlens. The front mirror surface adopts a refractive surface type formed by CNC turning or molding in a spectacle lens lathe, and the rear mirror surface adopts a refractive surface type formed by CNC turning in a spectacle lens lathe.

[0063] The present invention provides a double-mirror double-positive addition individualized defocus spectacle lens. This spectacle lens adopts double-mirror double-sided positive addition. The base positive addition formed by the microlens array is adopted in the peripheral area of the front mirror surface, which has a relatively large refractive power positive addition. The peripheral area of the rear mirror surface adopts a refractive lens and is formed by CNC turning in a lathe, with an accurate turning accuracy of 0.01 degrees, achieving the customization of individualized difference lenses. This spectacle lens produces unexpected technical effects and has outstanding substantive features and remarkable progress.

[0064] Finally, it should be clarified that the design parameter changes and modifications to the central area, peripheral area, central correction area, and peripheral treatment area described in the invention are also within the scope of the rights defined in the present invention.
