Abstract
The utility model discloses an inward prism combined prevention and control lens with a built-in substrate gradually, which has the advantages of simple structure, low cost and strong practicability, and comprises a far-viewing auxiliary area, wherein the inside of the far-viewing auxiliary area is a far-viewing optical center, the bottom of the far-viewing optical center is a triangular prism, the triangular prism is a near prevention and control area, and the center of the lens is a transition zone; the combined prevention and control lens with the built-in substrate and the built-in prism gradually improves the practicability of the lens through the synergistic effect of all parts, saves a large amount of cost, and is suitable for popularization and use.
Description
Technical Field
The utility model relates to a lens, in particular to interior gradual built-in basement is to interior prism combination formula prevention and control lens.
Background
At present, in the field of myopia prevention and control of students, the learning and control synchronization can be better achieved, and the prevention and control products which are convenient and fast to use only have integrated double-light prevention and control lenses with the highest maturity, but also have defects in the aspects of data optimization, personalized customization, lens attractiveness and large image jump, so that the group acceptance cannot be better broken through, and the compliance is poor (comparing with a common single-light and a common progressive lens), while the lens firstly integrates an inner progressive design technology and a prism-convex combined lens (a base inwards combines a prism and an add positive lens under add a positive lens), utilizes visual function detection, carries out personalized customization according to instant data such as myopia outer hidden skew amount, adjustment lag amount and positive and negative adjustment force range of different children, realizes the three-in-one of the attractiveness, comfort and prevention and control effects, solves the problems of large image jump area and insufficient attractiveness of the double-light prevention and control lenses, and better combines the psychological needs of teenagers, the acceptance is higher, the practicability is stronger, the prevention and control effect is better, and therefore, the combined prevention and control lens with the built-in substrate and the inward prism gradually has good market prospect.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a built-in basement in gradually and to the combination formula prevention and control lens of interior prism, convenient to use has practiced thrift a large amount of costs.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides an interior gradual built-in basement is to interior prism combination formula prevention and control lens, including looking far auxiliary area, look far auxiliary area inside for far optical center, far optical center bottom is the prism, prism department is near with preventing and control the region, and lens center department is the transition zone.
As an optimal technical solution of the present invention, the far-vision auxiliary area is a concave lens.
As a preferred technical scheme of the utility model, the prism is the basement inwards 1-6.
As an optimized technical scheme of the utility model, the transition zone is upwards and descends the region and steadilys decrease with 25 degrees, and the horizontal off-centre is about 2mm, near uses interpupillary distance.
As a preferred technical proposal of the utility model, the near prevention and control area is ADD plus polished plus +75- + 400.
The utility model discloses the beneficial effect who reaches is: the utility model has the advantages of simple structure, low in cost, and the practicality is strong, progressive technique combines the protruding modular lens of arris in the adoption in the aspect of the design, adopt instant data, realize individualized private customization, better solution the image hopping problem and the pleasing to the eye degree of lens, realized teenagers 'myopia group's compliance and the high combination of comfort level, perfect outward appearance has really been realized, high adaptation, the individual customization, it is convenient to use, many-sided advantages such as individual customization and study accuse synchronization have improved the practicality of lens, a large amount of costs have been practiced thrift, high durability and convenient use, and good economic benefits and social have, and is suitable for being generalized to use.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:
FIG. 1 is a schematic view of the subjective structure of the present invention;
in the figure: 1. a region of apparent distance assistance; 2. a far optical center; 3. a prism; 4. a transition zone; 5. a near preventive control area.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example (b): as shown in fig. 1, the utility model provides an interior gradual built-in basement is to interior prism combination formula prevention and control lens, including looking far auxiliary area 1, look far auxiliary area 1 inside for far optical center 2, far optical center 2 bottoms is prism 3, prism 3 is located to be near with prevention and control regional 5, and lens center department is transition zone 4.
In order to enable the inward-stepping built-in substrate inward prism combined prevention and control lens to be convenient to use and high in working efficiency, the far vision auxiliary area 1 is a concave lens, the triangular prisms 3 are inward 1-6 of the substrate, the transition zone 4 is formed by descending 25 degrees from an upward area to a downward area, horizontally decentered by about 2mm, and has a near pupil distance, and the near prevention and control area 5 is formed by adding +75- +400 under ADD plus polished.
The utility model discloses when using, add positive mirror and direct built-in basement inward prism 3 under the adoption progressive technology fuses add, closely adjust the minus burden, reduce hyperopia out of focus, refraction and displacement characteristic through the prism, correct outer stealthy to one side, eliminate double vision and obscure the vision, and utilize progressive technology, make the jump area of image slow down, effectively promote and wear the comfort level, the lens outward appearance of improvement, the acceptance that also makes the customer has had the breakthrough of matter, make the product possess stronger market popularization nature and higher teenagers' myopia colony acceptance! Thereby promoting the degree of cooperation and feeding back better myopia prevention and control effect.
Type, although the present invention has been described last with reference to the foregoing embodiments, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it will be apparent to those skilled in the art that modifications and equivalents may be made in the technical solutions described in the above embodiments, or some technical features may be substituted. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
