Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a multi-point defocus light scattering soft focus lens. Background Technology

[0002] Defocus lenses are specially designed eyeglass lenses based on the concept of "defocus." Defocus means that light rays do not fall directly on the retina, but in front of or behind it. Defocus lenses create different optical focal points in different areas of the lens, allowing light entering the eye to form a clearer image on the retina, thereby improving vision and reducing the burden on the eye's accommodation.

[0003] Existing lens mounting methods typically involve creating grooves along the edges of the lens before securing it to the frame. While the frame's retaining brackets provide stability, the lenses themselves are fragile, and creating grooves easily damages them. Adding adhesive strips around the lens is also problematic, as the glue dries and the strips can detach over time. Therefore, we propose a multi-point defocusing light-scattering soft-focus lens to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a multi-point defocusing light scattering soft-focus lens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-point defocused light scattering soft focus lens is designed, including a first lens and a second lens, a first annular groove is provided along the edge of the second lens close to the first lens, a second annular groove is provided on the side of the first annular groove away from the edge of the second lens, and the frontal projection of the second annular groove is perpendicular to the first annular groove.

[0006] An annular fixing seat is provided along the edge of the second lens. An "L"-shaped connecting seat is provided inside the fixing seat. One end of the connecting seat is fixed to the inner wall of the fixing seat, and the other end of the connecting seat is placed in the second annular groove. A limiting groove is provided along the outer wall of the fixing seat.

[0007] Preferably, the first lens and the second lens are bonded and fixed together.

[0008] Preferably, a plurality of first arc-shaped grooves are provided on the side of the first lens near the second lens, and a plurality of second arc-shaped grooves are provided on the side of the second lens near the first lens. The second arc-shaped grooves correspond to the first arc-shaped grooves, and a microlens is placed between the first arc-shaped grooves and the second arc-shaped grooves.

[0009] Preferably, the connecting seat is a flexible rubber block.

[0010] Preferably, the upper and lower ends of the frontal projection of the mounting base correspond to the first lens and the second lens, respectively.

[0011] Preferably, the side of the first lens away from the second lens is convex, and the side of the second lens away from the first lens is concave, with the curvature of the concave surface being smaller than that of the convex surface.

[0012] Preferably, a blue film is installed on the side of the first lens and the second lens that are relatively far apart, and a diamond film is also provided on the first lens, with the diamond film installed on the blue film.

[0013] The design scheme proposed in this utility model has the following beneficial effects in application:

[0014] 1. The multi-point defocus light scattering soft focus lens is placed in the annular groove through the connecting seat. After the first lens and the second lens are combined and fixed, the connecting seat can be clamped, so that the fixing seat is stable on the outside of the lens, which improves the fixing effect of lens installation.

[0015] 2. This multi-point defocusing light scattering soft focus lens provides a multi-point defocusing effect through the spaced arrangement of multiple microlenses. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4A multi-point defocus light scattering soft focus lens includes a first lens 1 and a second lens 3. A first annular groove 7 is formed along the edge of the second lens 3 near the edge of the first lens 1, and a second annular groove 8 is formed on the side of the first annular groove 7 away from the edge of the second lens 3. The frontal projection of the second annular groove 8 is perpendicular to the first annular groove 7, so that the annular grooves form an "L" shape in cross-section.

[0023] like Figure 3 and Figure 4 As shown, an annular fixing seat 9 is provided along the edge of the second lens 3. An "L"-shaped connecting seat 10 is provided on the inner side of the fixing seat 9. One end of the connecting seat 10 is fixed to the inner wall of the fixing seat 9, and the other end of the connecting seat 10 is placed in the second annular groove 8, so that the connecting seat 10 is completely placed in the annular groove. The L-shaped connecting seat 10 also provides sufficient restraint within the annular groove, reducing the possibility of the connecting seat 10 detaching from the annular groove. The first lens 1 and the second lens 3 are glued and fixed together, and the connecting seat 10 is an elastic rubber block, which allows the connecting seat 10 to fully fill the annular groove and also allows the two lenses to clamp the connecting seat 10, further improving the stability of the connecting seat 10 in the annular groove. During installation, a limiting groove 11 is opened along the outer wall of the fixing seat 9, so that the lens can be placed in the frame. At this time, the limiting strip of the frame will be placed in the limiting groove 11, thereby limiting the lens within the frame, thus completing the lens installation.

[0024] Furthermore, the upper and lower ends of the frontal projection of the fixing base 9 correspond to the first lens 1 and the second lens 3 respectively, and wrap and protect the outer wall of the entire lens. In actual use, adhesive can be applied between the fixing base 9 and the lens to further reinforce the fixing base 9 and the lens. The wrapping of the lens by the fixing base 9 also improves the anti-collision capability of the lens and reduces the probability of the lens being damaged by accidental collision.

[0025] It should be noted that, as Figure 1 and Figure 3 As shown, a plurality of first arc-shaped grooves 4 are provided on the side of the first lens 1 near the second lens 3, and a plurality of second arc-shaped grooves 5 are provided on the side of the second lens 3 near the first lens 1. The second arc-shaped grooves 5 correspond to the first arc-shaped grooves 4, and a microlens 2 is placed between the first arc-shaped grooves 4 and the second arc-shaped grooves 5 to form a multi-point defocused lens. The side of the first lens 1 away from the second lens 3 is a convex surface, and the side of the second lens 3 away from the first lens 1 is a concave surface, and the curvature of the concave surface is smaller than that of the convex surface.

[0026] Furthermore, a blue film 12 is installed on the side of the first lens 1 and the second lens 3 that are relatively far apart, to ensure the light transmittance of the lens while reducing radiation. A diamond film 6 is also provided on the first lens 1, which is installed on the blue film 12 to improve the hardness and wear resistance of the lens.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
