[0014] Microlens peripheral defocus lenses have greater convex lens refractive power, but microlenses cannot be customized for individual differences, especially with an accuracy of 0.01 degrees.
[0015] There are existing refractive and micro-lens peripheral defocus eyeglasses, and the positive value is that they are molded on a mirror surface.
[0016] In his latest research paper, Smith critically pointed out that his original design of the treatment area in the 360° area around the lens had design flaws, and proposed that the peripheral hyperopic defocus of the retina that induces eye growth is a local, regionally selective mechanism. The temporal retina dominates eye growth, and the nasotemporal peripheral defocus is asymmetric. Circular correction cannot eliminate peripheral anisometropia, and a new peripheral anisometropia hyperopicanisometropi is generated. 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 described in WO2012 / 012826A1 and WO2013 / 134825A1 the peripheral refractive power of retina in 1155 myopic eyes with a range of -2.27D±0.83D, and found that the 40° temporal side was greater than the nasal side with a peripheral refractive power of +0.83D.
[0017] The applicant conducted peripheral refraction tests on 1,809 myopic eyes and found that the greater the myopia, the greater the 40° hyperopic defocus of the temporal retinal periphery, and the greater the hyperopic refractive anisometropia value of the nasotemporal retinal periphery, with some maximum refractive anisometropia values being greater than +1.25D.
[0018] Regardless of whether it is a refractive or microlens peripheral defocus lens, using equal positive addition in the peripheral treatment area cannot correct the nasotemporal retinal peripheral hyperopic refractive anisometropia. Correcting the nasotemporal retinal peripheral refractive anisometropia is more scientifically meaningful for preventing and controlling myopia.
[0019] There is a need to develop new innovative designs for peripheral defocus lenses, and peripheral defocus lenses for myopia are still one of the technical challenges in the field of eyewear. Summary of the invention
[0020] The invention aims to provide a double-mirror double-positive value individualized defocus spectacle lens.
[0021] The purpose of the present invention is achieved through the following technical solutions:

The central area of the front mirror surface of such spectacle lenses is a plano lens, the central area of the back mirror surface is a 0.00D to -10.00D refractive lens, and the central areas of the front and back mirror surfaces are combined into a central correction area.

The double positive addition of the front and back mirror peripheral areas is combined into a total positive addition of +1.00D to +7.00D personalized peripheral treatment area. The individualized refractive power gradient difference of the differential positive addition or total positive addition is ±0.05D to ±0.25D, and the front and rear mirror peripheral areas are set with full annular equal positive addition, or the nasal peripheral area is set with a positive addition greater than the temporal peripheral area, and at least 5 positive addition gradient segments and 5 total positive addition sub-levels are set, among which:
[0023] Base positive value + differential positive value = total positive value of individualized peripheral treatment area;
[0024] The base positive value is 95% to 5% of the total positive value of the individualized peripheral treatment area;
[0025] The difference positive value ranges from 5% to 95% of the total positive value of the individualized peripheral treatment area;
[0026] The refractive power of the peripheral area of the front mirror = the base value;
[0027] The refractive power of the peripheral area of the rear mirror = the refractive power of the concave lens in the central correction area + the difference positive addition value;
[0028] The nasal peripheral area is larger than the temporal peripheral area with a positive value of +0.50D to +2.00D.
[0029] The central areas of the front and back mirror surfaces of this type of lens are perfectly circular, elliptical, or vertically windowed. The horizontal diameter along the optical center is 7mm to 14mm long, and the vertical diameter is equal to the diameter of the lens. The refractive power of the concave lens in the central correction area is customized according to the subjective optometry degree. The lower area of the windowed central area is set as a prism lens with a composite base facing the nose and a prism degree of 0.5Δ to 6.0Δ, or a prism lens with a base facing downward and a prism degree of 0.25Δ to 1.50Δ.
[0030] The full ring shape of the front mirror peripheral area means that the microlens array is within the 360° circumferential azimuth of the peripheral area, the semi-ring shape of the front mirror peripheral area means that the microlens array occupies 180° circumferential azimuth in the nasal peripheral area and the temporal peripheral area, and the fan ring shape of the front mirror peripheral area means that the microlens array is in the nasal peripheral area and the temporal peripheral area, and the inner arc shape is less than 180° circumferential azimuth, and the outer arc shape is ≤180° circumferential azimuth. Alternatively, the microlens array is set in the nasal peripheral area and the temporal peripheral area of the front mirror as a perfect circle, a vertical ellipse, a horizontal ellipse, an arc top shape, or the array forms an irregular shape. The rear mirror peripheral area is a full ring shape, or a perfect circle, a vertical ellipse, a horizontal ellipse nasal peripheral area and a temporal peripheral area, and a 2mm to 4mm gradient zone is set between the central area and the peripheral area, or the full ring shape or the perfect circle nasal peripheral area and the temporal peripheral area of the front mirror are composed of microlenses to form a gradient zone, surrounding the convex lens refracting lens.
[0031] The peripheral area of the front mirror surface is set to four quadrants, namely the upper quadrant, the lower quadrant, the nasal quadrant, and the temporal quadrant. Each quadrant occupies a 90° circular azimuth. The four quadrants are microlens arrays, or the nasal quadrant and the temporal quadrant are microlens sheets, and the upper quadrant and the lower quadrant are refractive lenses. The nasal quadrant has a greater positive value than the temporal quadrant, and the lower quadrant has a greater positive value than the upper quadrant.
[0032] The peripheral area of the front mirror surface is composed of multiple independent microlens arrays, and the microlenses are any shape of cylinder, square, pentagon, hexagon, rectangle, and the diameter or radial length of the microlens is in the millimeter level, micrometer level, or nanometer level, and the diameter is set to be 2.0mm to 5nm, and the height is 16μm to 0.1nm. At least five positive value gradient sections are set in the peripheral areas of the front and rear mirror surfaces, and the area from the edge of the central area to the optical center of 10mm to 11.9mm is 20% of the total positive value, the area from 12mm to 13.9mm is 40% of the total positive value, the area from 14mm to 15.9mm is 60% of the total positive value, the area from 16mm to 17.9mm is 80% of the total positive value, and the area from 18mm to 30mm is 100% of the total positive value. A concave lens or a plano lens with the same refractive power as the central correction area is set from 30mm from the center to the edge of the lens.
[0033] The diameter of the microlens is 1.0mm to 20μm, the height is 10μm to 10nm, 8 to 120 rings are set from the edge of the central area 20mm to 30mm away from the optical center, and 300 to 8000 independent microlenses are densely distributed. The front and rear mirror peripheral areas are at least 20mm to 28mm away from the optical center and are set to full positive value. The front mirror base positive value 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. The rear mirror difference positive value 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. The total positive value of the treatment area is +1.00D to +6.00D.
[0034] The difference positive value or total positive value is based on the hyperopic defocus degree of the individual wearer's nasal and temporal 40° retinal peripheral refraction test, and +0.50D to +2.50D is added to the nasal and temporal sides respectively. Or the positive value is added according to the factors that induce myopia in the individual wearer: parents with high myopia ≥-6.00D, myopia onset age earlier than 6 years old, myopia degree increase by more than -0.75D per year, axial length or retinal peripheral refraction increase per year, daily near-distance eye use time ≥8 hours, according to each inducing factor, add +0.10D to +0.50D, and add individual difference positive value of +0.50D to +2.50D. Depending on the degree of myopia, the total positive addition of the front and rear mirror peripheral areas shall be set to at least 5 total positive addition levels: +1.00D, +2.00D, +3.00D, +4.00D, +5.00D, or set to: +1.50D, +2.50D, +3.50D, +4.50D, +5.50D. Alternatively, 50% of the total positive added value is equally divided into the front mirror peripheral area and the back mirror peripheral area, the nasal peripheral area is larger than the temporal peripheral area with a total positive added value of +0.50D to +1.50D, the differential positive added value or the individual refractive power gradient difference of the total positive added value is ±0.05D to ±0.15D, the defocus lenses for near use are larger than the defocus lenses for far and near use with a positive added value of +0.50D to +2.00D, or additional lenses with a total positive added value of +1.00D to +5.00D are set, and the additional glasses frame is clamped on the ordinary glasses frame when using the eyes at close range.
[0035] The diameter of the microlens is 700μm to 100μm, and the height is 10μm to 1μm. The microlens is set on the front mirror surface, the back mirror surface or embedded in the lens matrix, and is 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 the refractive surface type of the lens CNC lathe or molded, and the rear mirror surface adopts the refractive surface type of the lens CNC lathe.
[0036] The front and rear mirror surfaces of this spectacle lens are both refractive lenses, and the front and rear mirror surfaces respectively include a central area and a peripheral area, a gradient area is set between the central area and the peripheral area, and the front and rear mirror peripheral areas are correspondingly set with a full ring, or the front and rear mirror peripheral areas are correspondingly set with a perfect circular nasal peripheral area and a perfect circular temporal peripheral area, or one side of the mirror peripheral area is set with a full ring, and the other side of the mirror peripheral area is set with a perfect circular nasal peripheral area and a perfect circular temporal peripheral area. The front and rear mirror central areas are compounded into a central correction area with a refractive power of 0.00D to -10.00D, or the refractive power of the central correction area is evenly divided into the front mirror central area and the rear mirror central area according to 50%, and the front and rear mirror peripheral areas are compounded into a total positive addition value of +1.00D to +6.00D. 50% of the total positive addition, +0.50D to +3.00D are set to the front and rear mirror peripheral areas, and the nasal peripheral area is greater than the positive addition of the temporal peripheral area. The refractive power of the front mirror peripheral area is 50% of the total positive addition, and the refractive power of the rear mirror peripheral area is the refractive power of the concave lens in the central correction area combined with 50% of the total positive addition. The total positive addition is set at 18mm to 30mm from the optical center, and the front and rear mirror refractive surface shapes are formed in a CNC lathe workshop.
[0037] The peripheral area of the front mirror surface is set to be a semi-circular shape, a fan-shaped ring shape, or the nasal peripheral area and the temporal peripheral area are set to be a perfect circle, a vertical ellipse, a horizontal ellipse, or an arc top shape. The peripheral area of the rear mirror surface is set to be a full ring shape, or set to be a perfect circle, a vertical ellipse, a horizontal ellipse nasal peripheral area and a temporal peripheral area, or the full ring or perfect circle nasal peripheral area and the temporal peripheral area of the front mirror surface are composed of micro lenses to form a gradient area, surrounding the convex lens refracting lens, the front mirror surface adopts a molded refractive surface type, and the rear mirror surface adopts a CNC lathe-molded refractive surface type.
[0038] The beneficial effects of the present invention compared with the prior art are:
[0039] 1. The refractive power of refractive peripheral defocus lenses is currently formed in a CNC lathe, and the refractive power can be accurate to 0.01D, but the transition between the central correction area and the peripheral treatment area needs to be smoothed with a progressive zone, and a positive addition value greater than +2.00D will produce severe astigmatism. Microlens-type peripheral defocus lenses can be set with a positive addition value of +3.00D to +4.50D, but individualized differential refractive power settings cannot be achieved.
[0040] 2. Now, whether the peripheral defocus lens is refractive or micro-lens type, its positive value is set on one side of the mirror surface, and the other side of the mirror surface is a concave lens.
[0041] 3. The present invention provides a microlens refractive eyeglass lens, wherein the front mirror microlens lens is a base positive value to ensure a larger positive value, and the rear mirror refractive lens is a differential positive value to ensure personalized and differentiated positive value customization, and the lens can be arbitrarily selected and customized within the positive value range of +1.00D to +6.00D and the positive value gradient difference of ±0.01D.
[0042] 4. Another face type of the present invention is a refractive eyeglass lens, wherein the front and rear mirror surfaces include a central area and a peripheral area respectively, and 50% of the total positive addition, +0.50D to +3.00D, is set to the front and rear mirror surface peripheral areas respectively, and the nasal peripheral area is greater than the positive addition of the temporal peripheral area, and the front and rear mirror surface peripheral areas are compounded to a total positive addition of +1.00D to +6.00D.

The peripheral area of the front mirror surface is composed of multiple independent microlenses, and the refractive power of the microlenses is set to +0.50D to +4.00D base plus value to meet the plus value needs of different myopia degrees. The refractive power of the peripheral zone of the rear mirror is the refractive power of the concave lens in the central correction zone combined with a differential positive addition refractive lens of +0.50D to +3.00D. The refractive power of the peripheral zone of the rear mirror is the differential positive addition added on the basis of the myopia degree. The dual positive additions of the front and rear mirror peripheral zones are combined to be a total positive addition of +1.00D to +7.00D for the individualized peripheral treatment zone. The individualized refractive power gradient difference of the differential positive addition or the total positive addition is ±0.05D to ±0.25D, and the refractive power gradient difference is set for individualized differential glasses wearers. The differential positive addition of the rear mirror adopts the workshop molding technology, and the refractive power can be accurate to 0.01D, so as to achieve individualized selection.
[0074] The front and rear mirror peripheral areas are set with full annular equal positive additions, or the nasal peripheral area and the temporal peripheral area are set, and the nasal peripheral area > the temporal peripheral area positive addition, in order to meet the myopic temporal peripheral retinal defocus distance greater than the nasal peripheral retinal defocus distance. At least 5 positive addition gradient segments and 5 total positive addition sub-levels are set in the peripheral area, including:
[0075] Base positive value + differential positive value = total positive value of individualized peripheral treatment area;
[0076] The base positive value is 95% to 5% of the total positive value of the individualized peripheral treatment area;
[0077] The difference positive value ranges from 5% to 95% of the total positive value of the individualized peripheral treatment area;
[0078] The refractive power of the peripheral area of the front mirror = the base value;
[0079] The refractive power of the peripheral area of the rear mirror = the refractive power of the concave lens in the central correction area + the difference positive addition value;
[0080] The nasal peripheral area is larger than the temporal peripheral area with a positive value of +0.50D to +2.00D.
[0081] The central area of the front and rear mirror surfaces is set to be a perfect circle, an ellipse, or a vertical radial window type according to the shape of the peripheral area. The central area is a vertical radial window type, with a horizontal radial length of 7mm to 14mm along the optical center, and the vertical radial length is equal to the diameter of the lens. The refractive power of the concave lens in the central correction area is customized according to the subjective optometry degree, and the lower area of the central area is set to a composite base facing the nose and a prism degree of 0.5Δ to 6.0Δ prism lens, or a base facing the lower side and a prism degree of 0.25Δ to 1.50Δ prism lens.
[0082] The full ring shape of the front mirror peripheral area means that the microlens array is within the 360° circular azimuth of the peripheral area, the semi-ring shape of the front mirror peripheral area means that the microlens array occupies 180° circular azimuth in the nasal peripheral area and the temporal peripheral area, and the fan-ring shape of the front mirror peripheral area means that the microlens array is in the nasal peripheral area and the temporal peripheral area, and the inner arc is less than 180° circular azimuth, and the outer arc is ≤180° circular azimuth. Alternatively, the microlens array is set in the nasal peripheral area and the temporal peripheral area of the front mirror as a perfect circle, a vertical ellipse, a horizontal ellipse, an arc top shape, or the array forms an irregular shape. The rear mirror peripheral area is set as a full ring shape, or the peripheral area is divided into two areas, the nasal peripheral area and the temporal peripheral area, and a perfect circle is set, and a 2mm to 4mm gradient area is set between the central area and the peripheral area. The gradient area integrates the central area and the peripheral area to reduce the refractive power jump phenomenon. Or the front mirror surface is completely annular or perfectly circular, the nasal peripheral area and the temporal peripheral area are composed of micro lenses to form a gradient zone, surrounding the convex lens refracting lens.
[0083] The peripheral area of the front mirror surface can be set to four quadrants, namely the upper quadrant, the lower quadrant, the nasal quadrant, and the temporal quadrant. Each quadrant occupies a 90° circular azimuth angle. The four quadrants are microlens arrays, or the nasal quadrant and the temporal quadrant are microlens sheets, and the upper quadrant and the lower quadrant are refractive lenses. The nasal quadrant has a greater positive value than the temporal quadrant, and the lower quadrant has a greater positive value than the upper quadrant.
[0084] The peripheral area of the front mirror surface is composed of multiple independent microlens arrays, and the microlenses are any shape of cylinder, square, pentagon, hexagon, rectangle. The diameter or radial length of the microlens is in the millimeter level, micrometer level, and nanometer level, and the diameter is set to 2.0mm to 5nm and the height is set to 16μm to 0.1nm. At least five positive value gradient sections are set in the peripheral areas of the front and rear mirror surfaces. The area from the edge of the central area to the optical center of 10mm to 11.9mm is a total positive value of 20%, the area from 12mm to 13.9mm from the center is a total positive value of 40%, the area from 14mm to 15.9mm is a total positive value of 60%, the area from 16mm to 17.9mm from the center is a total positive value of 80%, and the area from 18mm to 30mm from the center is a total positive value of 100%. From 30mm from the center to the edge of the lens, a concave lens or a plano lens with the same refractive power as the central correction area is set. The purpose of setting five positive-added gradient segments is consistent with the gradual increase in hyperopic defocus from the central to the peripheral retina in the myopic peripheral retina, which is more in line with the retinal peripheral defocus theory.
[0085] The microlenses are preferably set to have a diameter of 1.0mm to 20μm and a height of 10μm to 10nm. 8 to 120 rings are set from the edge of the central area 20mm to 30mm away from the optical center, and 300 to 8000 independent microlenses are densely distributed. The peripheral areas of the front and rear mirrors are set to full positive addition values at least 20mm to 28mm away from the optical center to correct the hyperopic defocus of the retinal periphery.
[0086] 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.
[0087] The difference positive value or total positive value is based on the hyperopic defocus degree of the individual wearer's nasal and temporal retinal peripheral refraction test of 40°, plus +0.50D to +2.50D for the nasal and temporal sides. Alternatively, the positive value is added according to the factors that induce myopia in the individual wearer: parents with high myopia ≥-6.00D, myopia onset age earlier than 6 years old, myopia degree increase by more than -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 rear 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.
[0088] 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, and the additional glasses frame can be clamped on the ordinary glasses frame when using the eyes at close range.
[0089] The microlens is set at the micron level, with a diameter of 700μm to 100μm and a height of 10μm to 1μm. The microlens is set on the front mirror surface, the back mirror surface or embedded in the lens matrix, and is composed of one, two, three or four layers. The thickness of the composite layer or coating layer is ≥ the height of the microlens.

The composite of the front and rear mirror peripheral areas is a total positive addition of +1.00D to +6.00D, and 50% of the total positive addition and +0.50D to +3.00D are set to the front and rear mirror peripheral areas respectively. The nasal peripheral area is greater than the temporal peripheral area positive addition, the front mirror peripheral area refractive power is 50% of the total positive addition, and the rear mirror peripheral area refractive power is the central correction area concave lens refractive power composite 50% of the total positive addition, and the total positive addition is set at 18mm to 30mm from the optical center, and the front and rear mirror refractive surface shape is formed in a CNC lathe.
