Description
Technical Field
The invention belongs to the technical field of optical lenses, and particularly relates to a progressive focal lens which is provided with a plurality of focal areas on one lens and changes the focal value of each focal area into progressive focal lenses which are sequentially arranged.
Background
The Chinese patent 201610092191.8, namely a progressive focal lens, provides a lens with a plane bottom surface and a free-form surface on the other side, wherein the free-form surface is composed of concave surfaces, a plurality of areas are arranged on the free-form surface, and the longitudinal lengths of the areas are equal. The length of the area is 0.1.0 mm-100 mm, the refractive power of the area is 1-2000 degrees, the refractive power is uniformly distributed on the lens, and the focal points are uniformly distributed in each unit length.
The defect of the 'progressive focal lens' is that the 'free-form surface' is used as a lens for training for correcting myopia, a regular training method matched with the 'free-form surface' is difficult to set, and the 'free-form surface' lens can only be used as a lens for training by manually moving the relative positions of the two lenses by a trained person. The lens with the free-form surface does not indicate the shape and structure of a plurality of areas, and the shape and structure of the plurality of areas are not known to be spherical, elliptic or trapezoid; the above-mentioned structure does not indicate what the refractive power is 1 to 2000 degrees in the length region of 0.1.0mm to 100mm, that is, the refractive power cannot be changed to 1 to 2000 degrees in the length region of 0.1.0mm to 100mm, and the refractive power is changed to 1 to 2000 degrees in the length region of 0.1.0mm to 100 mm. Therefore, the technical scheme cannot realize the effect of correction.
Chinese patent 201520246792.0, "an arbitrary zoom lens set," provides a: one surface of each lens is a horizontal plane, and the other surface of each lens is a non-horizontal curved surface which accords with the mathematical variation rule; the non-horizontal curved surface of the lens is provided with a highest point and a lowest point; a plurality of continuously-changed optical centers are uniformly distributed between the highest point and the lowest point of the non-horizontal curved surface of the lens along the non-horizontal curved surface of the lens; the diopter numbers of the optical centers are sequentially decreased or increased. The disadvantage is that the "rule of change in accordance with mathematics" does not indicate what rule is. The optical centers are uniformly distributed at intervals of 1.0mm, one optical center is only in a spherical shape structure, and the spherical shape structure is difficult to realize the training function of vision correction, because the sight line of a human eye passes through the lens at one point, each interval in the lens is an optical center point, and the two points of the sight line and the optical center point are difficult to coincide. Therefore, the technical scheme can not realize the training of vision correction and can not thoroughly solve the problems of asthenopia and the like. And the description of "non-horizontal curved surfaces" does not indicate what curved surfaces are.
Disclosure of Invention
The invention aims to provide a double lens group which can be regularly zoomed and relatively moved by a motor, and can generate regular diopter change, so that after the motor is controlled by a computer program, the double lens group can generate equidistant zoom point lens twill singlets in the double lens group used for correcting vision according to rules.
The structure of the invention:
the equidistant zoom point lens twill single piece used in the vision correction double lens group comprises two opposite light-transmitting surfaces, one is a flat smooth surface 1, and the other is an equidistant zoom multi-ripple surface 2; the method is characterized in that: the equidistant zooming multi-ripple surface 2 is formed by parallel and parallel arrangement of a plurality of equidistant width strip-shaped curved surfaces 3, so that the cross section of the equidistant zooming multi-ripple surface 2 is in an equidistant width zigzag structure,
the strip width d of each side-by-side equidistant-width strip-shaped curved surface 3 is equal, and the range of each strip-shaped width d is a certain value between 0.1mm and 5.0mm;
the lens diopter values of the same equidistant width strip-shaped curved surface 3 are the same, and all lens focuses of the same equidistant width strip-shaped curved surface 3 are on the same straight line;
lens focus connecting lines of all the strip-shaped curved surfaces 3 with equal widths are parallel to each other;
the lens diopter value range N is a value between 10 and 100 degrees;
all equidistant width strip-shaped curved surfaces 3 are arranged side by side, and the diopter values of the lenses are the same;
the lens twill single-piece body has one side which is a lens straight edge 4, and the included angle a between the separation line 5 between any two adjacent equidistant width strip-shaped curved surfaces 3 and the lens straight edge 4 is a certain value between 70 degrees and 85 degrees.
Any cross-section lens diopter values perpendicular to the central axis of the same equidistant-width strip-shaped curved surface 3 in the equidistant-variable focus lens twill single sheet are the same, all focuses of the same equidistant-width strip-shaped curved surface 3 form a straight line, and the connecting line of the focuses of the same equidistant-width strip-shaped curved surface 3 is parallel to the central axis.
Since the angle a between the separation line 5 of any two adjacent equidistant-width strip-shaped curved surfaces 3 and the straight edge 4 of the lens is a certain value between 70 degrees and 85 degrees, the angle between the focal point connecting line of each equidistant-width strip-shaped curved surface 3 and the straight edge 4 of the lens is the same, and the angle between the focal point connecting line of each equidistant-width strip-shaped curved surface 3 and the straight edge 4 of the lens is a certain value between 70 degrees and 85 degrees.
The application of the invention: the equidistant zoom lens twill single piece is a single component for combining two single pieces, and the combination method is to use a double-piece structure mode that the smooth surface 1 of one equidistant zoom lens twill single piece and the smooth surface 1 of the other equidistant zoom lens twill single piece are adhered to form a gapless and mutually relatively sliding. If the diagonal single sheet and the straight line single sheet are 40 equidistant width strip-shaped curved surfaces 3, and each equidistant width strip-shaped curved surface 3 of the diagonal single sheet and the straight line single sheet is the same width, if the same width is 1.0mm, the two single sheets which can slide relatively to each other can generate different combined lens diopter values at different sliding positions, theoretical calculation should be performed, 40 x 40 = 1600 combined lens diopter values, and the 1600 combined lens diopter values generated by the two equidistant zoom point lens diagonal single sheets are helpful for the zooming training of one eye, so that the recovery of vision of a patient with myopia is facilitated. Thus, the diagonal single lens of the present invention is a single lens for use with two-piece vision correction glasses.
The combined structure of the double-piece twill single piece and the straight-line single piece is different from the combined structure of the double-piece two straight-line single pieces in zooming training. [A] When the double-piece is in a combined structure of two straight-line single pieces, in the two straight-line single pieces, focal lines of the strip-shaped curved surfaces 3 with equal-distance widths are only overlapped and not overlapped, namely, the sight line of eyes stays at one position to wait for overlapping of the two focal lines for zooming training. [B] When the double sheets are in a combined structure of the twill single sheets and the straight line single sheets, in the two single sheets, the focal points of the equidistant width strip-shaped curved surfaces 3 form an included angle structure with a certain value between 70 degrees and 85 degrees, the focal points are overlapped to form an overlapped point, and the overlapped point is the intersection point of the two focal lines. When the twill single sheet and the straight line single sheet relatively move, the intersection point of the two focal lines moves, and the coincident point of the two focal lines also moves, so that training content is added to vision correction zooming training, and importantly, the movement of eyeballs is greatly increased in the vision correction zooming training with the coincident point of the two focal lines moving, the vision correction effect is better, and the time for recovering vision is shorter.
Preferably, the width d of each strip is in the range of a certain value between 1.00mm and 2.00 mm.
Preferably, the lens diopter value range N of any two adjacent equidistant-width strip-shaped curved surfaces 3 is a value of one of 20 degrees, 25 degrees, 50 degrees, 75 degrees, and 100 degrees.
Preferably all equidistant width strip curves 3 are arranged side by side and the lens diopter values N are the same, the specific arrangement distribution of lens diopter values 200 degrees to-1000 being as follows in table 1:
TABLE 1
Table 1 above shows:
ordinal number refers to: 1 to 25 are serial numbers of 25 equidistant width strip-shaped curved surfaces 3;
the degrees refer to: lens diopter values of equidistant width strip surface 3 for each serial number;
width means: the strip width d of each equidistant width strip-shaped curved surface 3 side by side is 1.50mm;
the lens diopter value range N in the above table is 50 degrees.
The equidistant variable focal length lens twill single piece of the equidistant variable focal length multi-corrugated surface 2 described in table 1 is suitable for the group of 18 years to 40 years, because the combined lens can generate 25 x 25 = 625 combined lens diopters in the sliding of the two single pieces, and the diopter change area of the 625 combined lenses ranges from 400 degrees to-2000 degrees. The reason why the range of the variation area is 400 degrees to-2000 degrees is applicable to the 18-40-year-old population is that the lens is decided to be used according to the eye habit of the adult population, the length of the eye axis and the interpupillary distance.
Preferably all equidistant width strip curves 3 are arranged side by side and the lens diopter values N are the same, the specific arrangement distribution of lens diopter values 200 to-800 being as follows in table 2:
TABLE 2
In table 2 above:
ordinal number refers to: 1 to 41 are serial numbers of 41 equidistant width strip-shaped curved surfaces 3;
the degrees refer to: lens diopter values of equidistant width strip surface 3 for each serial number;
width means: the strip width d of each equidistant width strip-shaped curved surface 3 side by side is 1.0mm;
the lens diopter value range N in the above table is 25 degrees.
The equidistant variable focal length lens twill single piece of the equidistant variable focal length multi-corrugated surface 2 described in table 2, which is composed of two single pieces sliding relative to each other, is suitable for the group of 12 years old to 18 years old because it can generate 41 x 41 = 1681 combined lens diopters in the sliding of the two single pieces, and the range of the diopter change of the 1681 combined lens is 400 degrees to-1600 degrees. The reason that the range of the change area is 400 degrees to-1600 degrees is suitable for the group of 2 years old to 18 years old is that the lens is used according to the habit of eyes of the young people, the length of the eye axis and the interpupillary distance.
Preferably all equidistant width strip curves 3 are arranged side by side and the lens diopter values N are the same, the specific arrangement distribution of lens diopter values 200 degrees to-600 being as follows in table 3:

width means: the strip width d of each equidistant width strip-shaped curved surface 3 side by side is 1.0mm;
the lens diopter value range N in the above table is 20 degrees.
The equidistant variable focal length lens twill single piece of the equidistant variable focal length multi-corrugated surface 2 described in table 3, which consists of two single pieces sliding relative to each other, is suitable for the group under 12 years old because it can generate 41 x 41 = 1681 combined lens diopters in the sliding of the two single pieces, and the range of diopter change of the 1681 combined lens ranges from 400 degrees to-1200 degrees. The reason that the range of the change area is 400-1200 degrees is suitable for the people under 12 years old is that the lens is decided to be used according to the eye habit of the children, the length of the eye axis and the development condition of the interpupillary distance.
The invention has the advantages that:
when the double sheets are in a combined structure of the twill single sheets and the straight line single sheets, focal lines of equidistant width strip-shaped curved surfaces of the two single sheets form an included angle structure with a certain value between 70 degrees and 85 degrees, the focal lines are overlapped to form an overlapped point, and the overlapped point is the intersection point of the two focal lines. When the twill single sheet and the straight line single sheet relatively move, the intersection point of the two focal lines moves, and the coincident point of the two focal lines also moves, so that training content is added to vision correction zooming training, and importantly, the movement of eyeballs is greatly increased in the vision correction zooming training with the coincident point of the two focal lines moving, the vision correction effect is better, and the time for recovering vision is shorter.
The single chip is conveniently controlled to be shifted to the set diopter position of the synthetic lens by a computer, so that the diopter value of the synthetic lens can be controlled by the diopter of the synthetic lens: the lens diopter values of three different units in the same lens straight grain single sheet are the same in the meaning that when the motor is controlled by a computer program to drive the two lens straight grain single sheets to displace, the displacement speed has a fixed functional relation with the synthesized lens diopter values of two equidistant width strip-shaped curved surfaces at each position of the two straight grain single sheets, namely the synthesized lens diopter values at each position can be controlled by the displacement speed between the two single sheets.
When two straight line single sheets are combined into a lens, each equidistant width strip curved surface can be combined into a combined lens with a set diopter value, and other equidistant width strip curved surfaces in the two straight line single sheets can be combined into a combined lens with a set diopter value, so that an imaging-incapable area cannot be generated.
The invention can be used as a single component used in combination of two single sheets, and in a common eye lens with the length of 30-55 width, 10 to 100 equidistant width strip-shaped curved surfaces can be arranged in the invention, so that the two single sheets can slide relatively to each other to generate 100 to 10000 different combined lens diopter effects, and a large number of combined lens diopters which can be changed along with the relative sliding of the two single sheets are good methods for zooming training of eyes and helping myopic patients to recover vision. The equidistant varifocal lens twill single chip can be used as a component of glasses for zooming training of eyes and helping myopic patients to recover vision.
