Description
Technical Field
The utility model relates to a multi-point defocused lens and frame glasses with the same, and belongs to the technical field of defocused lenses.
Background
Myopia is a common refraction problem, and myopia prevention and control are usually carried out by optical means in clinic at present, but the lenses used by the myopia prevention and control are different due to the difference of vision and eye states. The multi-point defocusing lens is a common clinical lens, and the lens surface of the multi-point defocusing lens generates conchoidal bending force, so that the far-vision defocusing of retina and even the near-vision defocusing can be reduced, and the purpose of delaying the near-vision progress can be achieved.
However, the existing multi-point defocus lens adopts a design method of linearly fixing the defocus amount, and the defocus amount is applied by a knife without considering the refractive power of a myopic patient with malrefraction, so that the defocus amount may be over-corrected.
In view of the above prior art, the present inventors found that the contact position between the edge of the microlens attached to the front surface of the lens and the lens circle is second-order non-conductive, and a stray light band of a high-cylindrical lens is generated, and the larger the defocus amount, the larger the stray light band. Since most myopic patients are teenagers and children, eyeballs are not developed, and interference astigmatism is caused when eyes wear the myopia patients for a long time, so that astigmatism of the myopic patients without astigmatism is possibly increased.
Disclosure of Invention
In order to solve the technical problems, the utility model aims to provide a multi-point defocused lens and a frame eyeglass with the same.
In a first aspect, the present utility model provides a multi-point defocus lens comprising: a lens substrate;
the lens comprises a lens matrix, a plurality of groups of defocusing areas, a plurality of lens matrix and a lens cover, wherein the defocusing areas are outwards diffused and nested along the geometric center of the lens matrix, and each group of defocusing areas are formed into a ring shape and are arranged at equal intervals.
Through above-mentioned technical scheme, the structure of current multiple spot defocusing lens is optimized to this application technical scheme, through the regional setting of many defocuses, has improved the setting of traditional single defocusing region and has led to bringing the astigmatic problem of intervention after wearing for a long time to when effectively adjusting and improving the myopia problem, improve the emergence that the astigmatic problem appears in the person of wearing.
Further, each group of the defocused areas comprises at least two circles of lens rings, and each circle of lens rings is formed by a plurality of micro lenses in an annular array along the geometric center of the lens matrix; the defocusing areas are 4 groups, wherein the first defocusing area is the innermost ring, and the second defocusing area, the third defocusing area and the fourth defocusing area are formed by sequentially diffusing from inside to outside.
Through above-mentioned technical scheme, this application is established defocusing region into 4 groups, through further subdivision to defocusing region, improves single defocusing volume and leads to the astigmatic problem of appearing after the patient wears.
Further, the defocus amount of the second defocus region is greater than the remaining defocus amounts of the remaining defocus in the defocus region.
Further, the defocus amount of the second defocus region is 4.50 to 5.50D.
Because the applied myopia defocus intervention should occur within a 20 degree angle of view from the fovea of the macula in order to continue to slow down the increase in the eye axis, the effect is best when the applied myopia defocus occurs within a 15 degree angle of view from the fovea of the macula, so for this purpose, the present application sets the second defocus region to within a 15 degree angle of view from the fovea of the macula, by increasing the application of defocus in this region, the rest of the region reduces the application of defocus, thereby avoiding over-correction, improving comfort and achieving myopia prevention.
Further, the first defocusing area is provided with two circles of lens rings, each circle of lens ring is internally provided with a plurality of micro lenses, and the diameter of each micro lens is 0.9mm.
Further, the second defocusing area is provided with three circles of lens rings, each circle of lens ring is internally provided with a plurality of micro lenses, and the diameter of each micro lens is 1.0mm.
Further, the third defocusing area is provided with three circles of lens rings, each circle of lens ring is internally provided with a plurality of micro lenses, and the diameter of each micro lens is 1.1mm.
Further, the third defocusing area is provided with five circles of lens rings, each circle of lens ring is internally provided with a plurality of micro lenses, and the diameter of each micro lens is 1.2mm.
Through the technical scheme, the size of the lens forming the lens ring in the defocusing area is further optimized, and the lens in the defocusing area forms a scattering symmetrical distribution structure by selecting the scheme of sequentially increasing from inside to outside, so that a good continuous defocusing intervention effect is achieved.
Further, the distance between the lens rings is 0.3mm for each circle.
Through above-mentioned technical scheme, this application has optimized the interval distance between the lens ring, avoids in the lens processing because of the error of cutter radius leads to lens to cut excessively and the accumulational phenomenon of lens, has effectively improved the lens simultaneously at follow-up injection molding, pouring thermosetting, photocuring and has led to substrate lens defocus loss uncontrollable, vision quality poor, the uncomfortable problem of formation of image.
In a second aspect, the present application provides a frame eyeglass employing a multi-point defocus lens as set forth in any one of the preceding claims.
By the technical scheme, the multipoint defocused lens prepared by the technical scheme has good effect of preventing over-applied correction, so that the frame glasses prepared by the method also have the excellent properties.
By means of the scheme, the utility model has at least the following advantages:
first, this application technical scheme optimizes the structure of current multiple spot defocusing lens, through the regional setting of many defocuses, has improved the setting of traditional single defocusing region and has led to bringing the astigmatic problem of intervention after wearing for a long time to when effectively adjusting and improving the myopia problem, improve the emergence that the astigmatic problem appears in the person of wearing.
Second, this application has optimized the interval distance between the lens ring, avoids the lens to cut excessively and the accumulational phenomenon of lens because of the error of cutter radius in the lens processing, has effectively improved the lens simultaneously at follow-up injection molding, pouring thermosetting, photocuring and has led to substrate lens defocus loss uncontrollable, vision quality poor, uncomfortable problem of formation of image.
Thirdly, because the applied myopia defocus intervention should occur within a 20-degree angle of view from the fovea of the macula for continuously slowing down the increase of the eye axis, the effect is best when the applied myopia defocus occurs within a 15-degree angle of view from the fovea of the macula, so for this purpose, the present application sets the second defocus region within a 15-degree angle of view from the fovea of the macula, by increasing the defocus amount applied in this region, the rest regions reduce the defocus amount applied, thereby avoiding over-correction and improving comfort to achieve the myopia prevention and control effect;
on the basis, the defocus amount can be adjusted according to actual demands, namely the actual myopia degree of a wearer, and the defocus amount is applied completely, so that over-correction and over-application are avoided, and wearing comfort is improved.
