It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The applicant finds that whether the peripheral retina hyperopia defocus popular in children with myopia or the peripheral retina hyperopia defocus which is easy to appear in children with hyperopia exists, the phenomenon that the defocus amount is different between the nasal side and the temporal side exists, and the defocus amount difference is more obvious along with the increase of the field angle, but the existing defocus lens is lack of a targeted defocus design for the nasal side and the temporal side with different field angles of human eyes, and therefore improvement is needed.

Referring to fig. 1, there is provided a multidirectional differentiated out-of-focus spectacle lens, comprising: a lens body 100, the lens body 100 comprising an optical center 101; a first out-of-focus setting area 102 and a second out-of-focus setting area 103 are arranged on the lens body 100, and the first out-of-focus setting area 102 and the second out-of-focus setting area 103 are rotationally and symmetrically distributed by taking an optical center 101 as a center; a plurality of groups of first annular zones 200 surrounding the optical center 101 are arranged in the first defocus setting area 102, and the first annular zones 200 are arranged from the optical center 101 to the side far away from the second defocus setting area 103; a plurality of groups of second annular bands 300 surrounding the optical center 101 are arranged in the second defocus setting area 103, and the second annular bands 300 are arranged from the optical center 101 to the side far away from the first defocus setting area 102; wherein, the first zone 200 and the second zone 300 extend to the boundary of the first defocus setting area 102 and the second defocus setting area 103, respectively; the first zone 200 and the second zone 300 are staggered in sequence at the interface and in a radial direction of the lens body 100.

The nasal side and the temporal side are divided by taking the vertical axis of the optical center 101 of the spectacle lens as a symmetry axis, one side close to the nose is the nasal side, and one side close to the ears is the temporal side. It can be understood that the first defocus setting area 102 and the second defocus setting area 103 defined in the present application are only relative concepts, and besides corresponding to the nasal side and temporal side areas, the present application can also correspond to the upper side and lower side of the human eye or equally divide the human eye into a plurality of areas at concentric angles of 10 ° to 180 °, and perform a targeted and personalized hyperopic defocus compensation design by measuring the hyperopic defocus of each area and determining the position of the spectacle lens where the micro lens is located according to the corresponding field angle in each area equally divided within the concentric angle, so as to further suppress the further development of the refractive error of the eye in all directions.

In some embodiments, the first zone 200 comprises a plurality of sets of first microlenses 201, and the second zone 300 comprises a plurality of sets of second microlenses 301; in each first zone 200, the first microlenses 201 are connected to each other or spaced apart from each other; in each of the second bands 300, the second microlenses 301 are connected to each other or spaced apart from each other. Specifically, as shown in fig. 1, each of the first microlenses 201 in the first zone 200 are connected to each other, and each of the second microlenses 301 in the second zone 300 are connected to each other; it will be appreciated that in some other arrangements, the first microlenses 201 in the first zone 200 and the second microlenses 301 in the second zone 300 are spaced apart from one another, i.e. each microlens is a separate structure, as shown in fig. 2; in still other arrangements, with the first defocus setting area 102 and the second defocus setting area 103 as boundaries, that is, arrangements including an arrangement spaced from each other and an arrangement connected to each other are included between the first microlenses 201 in the first defocus setting area 102, and arrangements connected to each other are included between the second microlenses 301 in the second defocus setting area 103, as shown in fig. 3. The above only shows the design of a part of the first zone 200 and the second zone 300, but in any form, the staggered arrangement at the boundary of the first defocus setting area 102 and the second defocus setting area 103 should be satisfied to satisfy the requirement of performing targeted defocus compensation on defocus amounts of different areas.

In some embodiments, the first annular zone 200 and the lens body 100 together form a first dioptric area 400, and the defocusing amount of the first dioptric area 400 increases as the field angle increases; the second annular band 300 and the lens body 100 jointly form a second bending area 500, and the defocusing amount of the second bending area 500 increases along with the increase of the field angle; the first defocus setting area 102 and the second defocus setting area 103 together form a third refraction area 600; the defocus amount of the first dioptric refraction area 400 is larger than the defocus amount of the third dioptric refraction area 600, and the defocus amount of the second dioptric refraction area 500 is larger than the defocus amount of the third dioptric refraction area 600. When the defocus setting requirement is met, defocus amounts under different field angles can be compensated pertinently, and annular bands in different defocus setting areas are arranged in a staggered mode in the radial direction of the lens body, so that the periphery of a retina of a wearer can obtain competitive defocus signal stimulation which is more reasonable and pertinence, the intervention effect of the lens on the development of the eye axis is improved, and the deepening of a refractive cloth matrix caused by the abnormal development of the eye axis can be further inhibited.

In some embodiments, referring to fig. 4, competitive defocus specifically refers to the region outside the optical center 101 of a pupil diameter saccade through which the wearer can clearly see objects in front by passing incident light through the third dioptric region 600 of the lens body 100 with the focus falling on the retina, forming a positive focus, i.e., the end point of the solid line in fig. 4, while the region outside the retina, i.e., the end point of the dotted line in fig. 4, forms defocus with other light passing through the first dioptric region 400 and the second dioptric region 500 with the focus falling on the retina, forming a region through which the wearer cannot clearly see objects in front. Within the same saccade range of the pupil, the vicinity of the positive focus is accompanied by the signal of the out-of-focus image, and the positive focus and the out-of-focus compete with each other, thereby stimulating the self-adaptive development of the eye axis to inhibit the further occurrence of the ametropia of the teenagers.

In some embodiments, the defocus amount of the first dioptric area 400 has a maximum value D _1max And a minimum value D _1min The defocus amount of the second dioptric area 500 has a maximum value D _2max And a minimum value D _2min And satisfies the following conditions: d is not more than 0.25D _2min -D _1min Not more than 2.0D, and not less than 0.25D _2max -D _1max Less than or equal to 5.7D. When the above relation is satisfied, the temporal defocus amount can be ensured to be larger than the nasal defocus amount, so that the defocus amount of each microlens increases as the field angle increases from the side close to the optical center 101 outwards, and therefore, a more reasonable competitive defocus signal can be formed at the periphery of the retina of the wearer, and further occurrence and development of the eye axis of teenagers can be interfered more effectively.

In some embodiments, in order to further provide the stimulating effect of the competitive defocus, the defocus amount of the first dioptric region 400 is 1.1 to 50 times, preferably 1.1 to 15 times, the defocus amount of the third dioptric region 600 corresponding to the position of the first dioptric region 400; the defocus amount of the second dioptric region 500 is 1.2 to 60 times, preferably 1.5 to 20 times, the defocus amount of the third dioptric region 600 at the position corresponding to the second dioptric region 500. When the requirements of the above multiples are met respectively, an overkill effect can be formed at least for the amount of far-vision defocus, the defocus amount proportion of the second refraction area 105 relative to the third refraction area 600 at the same position is slightly higher than that of the first refraction area 400 relative to the third refraction area 600 at the same position, and the requirement that the defocus amount of the second defocus setting area 103 is larger than that of the first defocus setting area 102 is further met, so that a more reasonable competitive defocus signal is formed around the retina of a lens wearer, and the increase of the axis of the eye is interfered more effectively.

In some embodiments, defocus is the absolute value of the difference between the refractive power of a single microlens and the average refractive power of the optical center of the lens body, where the maximum value D is _1max The expression of (a) is: d _1max ＝|d _1max -D ₀ L, |; minimum value D _1min The expression of (a) is: d _1min ＝|d _1min -D ₀ L, |; maximum value D _2max The expression of (a) is: d _2max ＝|d _2max -D ₀ L, |; minimum value D _2min The expression of (a) is: d _2min ＝|d _2min -D ₀ L, |; in the formula (d) _2max Denotes the maximum refractive power of the second microlens 301, d _2min Denotes the minimum refractive power of the second microlens 301, d _1max Denotes the maximum refractive power of the first microlens 201, d _1min Denotes a minimum refractive power, D, of the first microlens 201 ₀ Representing the average power of optical center 101. Through the setting of differentiating the out of focus volume of first bending region 400 and second bending region 500 to the requirement of different sight directions is met, through out of focus, the mutual stimulation of positive focus in order to reach the development of eye axis self-adaptation.

In some embodiments, the maximum value D of the defocus amount of the first dioptric area 400 _1max And minimum value D _1min The maximum value D of defocus of the second dioptric area 500 _2max And a minimum value D _2min Further satisfies: 4.3D ≤ D _1max ≤7.0D；2.5D≤D _1min <4.3D；4.5D≤D _2max ≤10.0D；3.0D≤D _2min <4.5D.
