Description

Technical Field

[0001] The utility model relates to the technical field of lens preparation, in particular to a multi-point defocusing lens. Background Art

[0002] The multi-point defocusing lens is a resin lens product designed based on the principle of myopic defocus. In addition to having the function of refractive correction, it can also effectively prevent the myopia of teenagers from deepening. It adopts a concentric circle defocus design, integrating the correction area (central image) and the defocus area (peripheral image). The correction area can correct the child's vision and ensure clear imaging in the center of the child's retina; the defocus area defocuses the light rays imaging in front of the retina continuously behind the retina, effectively preventing the eye axis from growing too fast backward, thereby effectively controlling the growth of myopia degrees. Currently, most multi-point defocusing lenses have two diopters, one matching the wearer's vision and the other for defocus stimulation of a fixed diopter. However, the fixed diopter defocus amount will bring different defocus stimulations to the wearer when looking at distant and near objects, which is likely to cause the aggravation of myopia, and the lens diopter is fixed, making it difficult to adjust the actual wearing experience of the wearer. Therefore, this application provides a multi-point defocusing lens. Content of the Utility Model

[0003] To solve the above technical problems, the utility model proposes a multi-point defocusing lens that can evenly cover the visual angle and can adjust the defocus amount according to the actual wearing experience.

[0004] The technical solution of the utility model is realized as follows:

[0005] A multi-point defocusing lens includes a periorbital frame, an outer frame, a microlens group, and a spherical mirror. Among them, outer lenses are detachably connected to the outside of both the periorbital frame and the outer frame. The microlens group is opened inside the outer lens. A proximal lens is movably connected inside the periorbital frame and the outer frame. A distal lens is movably connected to the outside of the proximal lens. The spherical mirror is fixedly connected to the outside of the proximal lens and the distal lens. The periorbital frame and the outer frame are fixedly connected by a fixing clip. Adjusting arms are fixedly connected to the outside of both the proximal lens and the distal lens.

[0006] Further, a sealing rotating ring is fixedly connected to the outside of the periorbital frame and the outer frame. A clamping groove is opened on the outside of the sealing rotating ring, and an injection groove is opened on the outside of the sealing rotating ring. The sealing rotating ring is in relative contact connection for sealing.

[0007] Furthermore, there are multiple groups of spherical mirrors, which are circumferentially distributed outside the proximal lens and the distal lens. The spherical mirrors are radially distributed at equal angles according to an inherent shape. The spherical mirrors outside the proximal lens and the distal lens are jointly combined into a lens matrix. A central optical area is provided at the center of the lens matrix, and the lens matrix presents a regular hexagon.

[0008] Furthermore, there are multiple groups of microlens groups, which are circumferentially distributed inside the outer lens. The microlens groups are combined into a regular hexagon. A central optical area is provided at the center of the microlens groups, and the central optical area presents a regular hexagon.

[0009] Furthermore, the spherical mirror is fitted and connected with the microlens group.

[0010] Furthermore, there are two groups of sealing rotary rings, which are symmetrically distributed outside the eye perimeter frame and the outer frame. The sealing rotary rings are in contact with each other to make the injection groove complete, and the clamping groove is movably connected with the adjusting support arm.

[0011] Furthermore, the fixed clamp connects the eye perimeter frame and the outer frame to each other, so that the eye perimeter frame and the outer frame can be freely opened and closed, and a lubricating medium is installed between the eye perimeter frame and the outer frame.

[0012] Furthermore, an embedded groove is provided outside the proximal lens, and a fitting convex ring is fixedly connected outside the distal lens. The embedded groove is fitted and connected with the fitting convex ring.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting the microlens group, the proximal lens, the distal lens and the spherical mirror, after the device is assembled, through the design that the optical center is a regular hexagon, while ensuring clear central vision, the development of myopia can be controlled and delayed through multiple focal points in the surrounding area, and it can effectively cover a wider peripheral area, providing a more comprehensive defocusing effect to prevent the excessive growth of the eye axis, thereby helping to control the increase of myopia degree.

[0015] 2. By setting the sealing rotary ring and the adjusting support arm, when needed, the wearer can drive the proximal lens and the distal lens to rotate by pressing the adjusting support arm, changing the fitting amount between the microlens group and the spherical mirror, so as to provide defocusing stimuli with different defocus amounts, which are respectively suitable for use when looking near and looking far, greatly improving the applicability of the device.

[0027] Specifically, during use, open the fixing clip 3 to open the eye - perimeter frame 1 and the outer frame 2 from each other.

During the closing process, fit the adjusting arm 13 with the clamping groove 8. After the two sealing rotating rings 5 come into contact and are sealed with each other, inject the lubricating medium into the space between the eye - perimeter frame 1 and the outer frame 2 through the injection groove 9.
