bi＝t×(tanθi-tanθi-1)+q；θi＝(1+k)θi-1k =0.05, and q is taken to be 1;
data for the ophthalmic lenses were obtained, the results of which are shown in table 1.
TABLE 1
The area of the saccadic spectacle lens is further calculated: considering the eye as a system of a single medium and refracting surfaces, see fig. 4, where the lens-eye distance is h, the pupil diameter is d, and the eye axis length is l, the formula is calculated according to the radius of the saccade area of the pupil on the lens: r = (d/2) × (h + l)/l, which is calculated by substituting the scope-eye distance h of 12mm, the pupil diameter d of 4mm and the axial length l of the eye of 24mm into the formula: the diameter of the area of the saccadic eye lens is 6mm.
From the results in Table 1, a + biThe maximum value is 2.57mm,2a and biAnd 2biThe maximum value of + a is 3.57mm and 4.08mm respectively, thus satisfying 2a + biAnd 2bi+ a is smaller than the saccadic diameter of pupil at the corresponding position of the field angle, and a + b<5mm. It is illustrated that the radial width of each zone in the microarray structure 20 and the spacing between zones meets the radial width requirements of the saccade of the pupil.

Example 2
The specific structure is the same as that of embodiment 1, except that a design surface for reducing the decentering farsightedness defocus at the side center is superimposed on the mother lens 10.
In some embodiments, a sheet of superimposed lenticule myopic out-of-focus lenses of 1.590 refractive index with a corrective power of-1.00D is made, e.g. with a base curve of 300; the microarray structure 20 is arranged on the first surface 104 of the mother mirror, the specific structure is the same as that shown in embodiment 1 and fig. 1, and the microlenses 202 are determined to be of spherical design, and the microlenses 202 are distributed in the range from 20 mm aperture to 60 mm aperture; the second surface 105 of the mother lens 10 is a design surface for reducing the side-center hyperopic defocus, the power variation and astigmatism variation are shown in fig. 5, and the first dioptric area 101 is 0.10D from the center to the edge of the mother lens 10. Referring to fig. 5, the compensation value corresponding to the position at the aperture of 10D may be set to 0.55D, and the compensation value of defocus at the aperture of 36 mm may be normalized to 0.90D. The diopter of the micro lens 202 is determined to be 3.00D, and 3.55D-3.90D of compensatory near-sighted defocus amount is formed after the design surfaces are superposed. The method has the advantages that reasonable retina periphery hyperopia defocus correction is met, meanwhile, the traditional diopter of the micro lens is changed into the diopter which is increased along with the increase of the field angle, the adaptability of wearing the lens is improved, and meanwhile the requirement of personalized defocus amount is met. Therefore, the design surface for reducing the side-center hyperopic defocus can be superposed to effectively improve the wearing comfort and meet the requirement of the personalized defocus amount.
In some embodiments, the microarray structure 20 of the present application is a zone 201 formed by a plurality of interconnected microlenses 202 arranged in a rotational symmetry about an optical center 106, the microlenses 202 having a refractive power different from that of the clear vision area of the master lens 10. The radial width of the annular zone 201 and the distance between the annular zone 201 and the annular zone 201 meet the requirement that the saccade area covers the third dioptric area and the annular zone but does not exceed the sum of the radial widths of the third dioptric area and the annular zone, so that the human eyes cannot cross two different functional areas when forming fixation through the peripheral area of the lens, and repeated image jumps are avoided when the eyes saccade. At the same time, the microlenses used can also produce a defocusing effect to slow down the progression of the ametropia of the eye.
