Description

Technical Field

[0001] The utility model relates to the technical field of photochromic lenses, in particular to a scratch-resistant and fast-response photochromic lens. Background Art

[0002] Photochromic lenses are lenses that darken when exposed to light of a certain wavelength (usually ultraviolet light). Photochromic lenses can be made of glass or plastics including polycarbonate. The color-changing effect is caused by silver chloride or other halides added to the lenses. These substances are transparent to visible light when not exposed to ultraviolet light. When exposed to ultraviolet light, they react rapidly to absorb some of the visible light, making the lenses appear dark. This chemical reaction is reversible, so when no longer exposed to ultraviolet light, the lenses will quickly return to their original transparent state.

[0003] When photochromic lenses are made into glasses and used for a long time, the outer side of the lens is exposed to the external environment for a long time. In addition, the glasses will be taken off when the wearer takes a rest. Under such conditions, the lens will inevitably come into friction contact with other materials, or be accidentally dropped, which will cause wear on the lens surface, making the lens no longer clear but blurry, thereby reducing the service life of the lens. Utility Model Content

[0004] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a scratch-resistant and fast-response photochromic lens.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a scratch-resistant fast-response photochromic lens is designed, comprising a first frame, a second frame is arranged inside the first frame, and the outer wall of the second frame is fixed to the inner wall of the first frame;

[0006] A first lens and a second lens are respectively arranged on both sides of the second frame, and a plurality of spaced limiting grooves are arranged along the edge of the first frame;

[0007] A transparent baffle is correspondingly arranged on the side of the first lens away from the second lens, and the baffle is in close contact with the first lens, and an inserting plate is installed along the edge of the baffle close to the first lens, and the length of the inserting plate corresponds to the depth of the limiting groove, and an elastic limiting block is installed on the other end of the inserting plate.

[0008] Preferably, the limiting block is an elastic rubber block.

[0009] Preferably, the side surfaces of the limiting blocks are all smooth arc-shaped sections.

[0010] Preferably, a transparent skirt is installed along the edge of one side of the baffle close to the first lens, and the skirt corresponds to the edge of the first lens.

[0011] Preferably, a color-changing layer is provided on the inner side of the second frame.

[0012] Preferably, a limit strip is installed on a side surface of the first frame.

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

[0014] 1. The scratch-resistant and fast-response photochromic lens can protect the first lens exposed to the outside by means of a baffle that is closely attached to the first lens, thereby preventing the first lens from being scratched and blurred due to contact and friction with foreign objects during use.

[0015] 2. The scratch-resistant, fast-response photochromic lens is placed in the limit groove through the plug plate, and the limit block is blocked on the side of the first frame away from the baffle to secure the baffle on the first frame, which not only ensures the stability of the baffle after installation, but also facilitates the removal of the baffle for replacement after wear.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4A scratch-resistant, fast-response photochromic lens comprises a first frame 1, on the side of which a limiting strip 5 is installed. It should be noted that the photochromic lens needs to be placed in a frame, and in order to facilitate the disassembly and assembly of the photochromic lens in the frame, a card slot is provided in the frame to fix the photochromic lens; in actual use, the limiting strip 5 corresponds to the card slot, so when installing the photochromic lens, the limiting strip 5 on the first frame 1 can be taken and placed in the card slot of the frame for fixing, and since the first frame 1 serves as a connector for the photochromic lens in the frame, even if the photochromic lens is repeatedly disassembled and assembled in the frame, the photochromic lens will not be damaged.

[0023] Specifically, a color-changing layer 3 is provided on the inner side of the second frame 2, that is, the color-changing layer 3 is provided between the two lenses. In actual use, the color-changing layer 3 is silver chloride or other halides filled between the two lenses, so that the two lenses and the color-changing layer 3 form a photochromic lens that can quickly change color under ultraviolet light.

[0024] like Figure 1 and Figure 2 As shown, a second frame 2 is arranged on the inner side of the first frame 1, and the outer wall of the second frame 2 is fixed on the inner wall of the first frame 1; a first lens 6 and a second lens 11 are respectively arranged on both sides of the second frame 2. In actual use, the first lens 6 is an outer lens, and the second lens 11 is an inner lens, that is, when worn, the second lens 11 is close to the wearer's eyes; in addition, the outer wall of the lens is close to the inner wall of the first frame 1, and the lens is fixed in the frame by gluing.

[0025] like Figure 2 As shown, a plurality of spaced limiting grooves 4 are provided along the edge of the first frame 1, a transparent baffle 7 is provided correspondingly on the side of the first lens 6 away from the second lens 11, and the baffle 7 is in close contact with the first lens 6, and an inserting plate 10 is installed along the edge of the baffle 7 close to the first lens 6, and the length of the inserting plate 10 corresponds to the depth of the limiting groove 4, and an elastic limiting block 9 is installed on the other end of the inserting plate 10, that is, the limiting block 9 is an elastic rubber block, wherein the formal projection of the end of the inserting plate 10 is located in the limiting block 9, and after the inserting plate 10 is inserted into the limiting groove 4, the limiting block 9 will be correspondingly stuck at the port of the limiting groove 4, thereby fixing the baffle 7 covering the first lens 6, so that the baffle 7 is in close contact with the surface of the first lens 6, thereby protecting the first lens 6.

[0026] Furthermore, in order to facilitate the removal of the baffle 7 from the first lens 6, the side surfaces of the limit block 9 are all smooth arc-shaped cross-sections, so that the contact position between the limit block 9 and the notch of the limit groove 4 is a smooth arc surface, thereby reducing the resistance of the notch of the limit groove 4 to the movement of the limit block 9, so that the baffle 7 can be more easily pulled off when disassembled.

[0027] It should be noted that, in order to better protect the first lens 6, Figure 2 and Figure 3 As shown, a transparent skirt 8 is installed along the edge of one side of the baffle 7 close to the first lens 6, and the skirt 8 corresponds to the edge of the first lens 6. During actual use, the skirt 8 corresponds to the edge of the first lens 6 protruding from the first frame 1. After the baffle 7 is covered on the first lens 6, the skirt 8 will also completely wrap the edge of the first lens 6, so that the first lens 6 is fully protected during use.

[0028] Specifically, the baffle 7 and the skirt 8 are both transparent plastic plates, which ensure protection for the first lens 6 without affecting the normal light transmittance of the lens. During long-term wearing and when the glasses are idle, the baffle 7 covers the first lens 6, so that foreign matter will only contact the baffle 7, thereby preventing the first lens 6 from being damaged by friction. Even if the baffle 7 is damaged by friction, it can be directly removed and replaced, which is convenient and does not affect the use of the photochromic lens.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
