Description

Technical Field

[0001] This utility model relates to the field of myopia correction glasses technology, and in particular to a vision correction glasses. Background Technology

[0002] Most wearers of vision correction glasses are students. In the classroom, students' eyes need to frequently adjust their focus between the blackboard and the book, which increases eye fatigue and can cause or aggravate myopia. Most existing vision correction glasses control or prevent myopia by relieving eye fatigue. For example, Chinese Patent No. CN205942148U discloses a type of glasses for relieving eye fatigue and treating myopia in teenagers. The glasses include a first frame, temples, and a nose pad support. A first lens is fixed on the frame. The nose pad support is connected to the first frame or the first lens through a snap-fit ​​structure. The glasses also include a second frame that is detachably connected to the snap-fit ​​structure. The snap-fit ​​structure includes a mounting strip that partially fits the lens or the outer wall of the frame. The mounting strip has a slot for the frame or lens to be inserted. The second frame has a second lens that can block light from directly hitting the first lens. The upper half of the second lens has several small holes, and the lower half has a through slot.

[0003] The existing primary lens is generally a bifocal lens, which consists of upper and lower visual zones with different powers. When worn, the upper visual zone is used for near vision through a pinhole, while the lower visual zone is used for near reading or writing. When the eye's focus shifts from a distant blackboard to a book on a desk, the power difference between the upper and lower visual zones reduces the lens's accommodation range, thus alleviating eye strain and fatigue. However, the field of vision through the pinhole is very small and the brightness is low, making it only suitable for near vision. In daily activities, most people are looking at distant objects. To ensure a normal field of vision, the secondary lens needs to be removed. Therefore, the secondary frame needs to be frequently disassembled and reassembled. During installation, the edges of the secondary frame need to be aligned and pressed into the slot. This process requires a certain degree of precision and time to align the secondary frame into the slot, making installation inconvenient. Therefore, there is still room for improvement in existing vision correction glasses. Utility Model Content

[0004] To address the drawback of existing vision correction glasses where the second frame requires time to align with the slot during installation, making installation inconvenient, the purpose of this invention is to provide vision correction glasses that are easy to install.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A vision correction eyeglass includes a frame with temples on both sides, a first lens inside the frame, a detachable lens cover on the frame, a second lens inside the lens cover, a hook on the lens cover for attaching the lens cover to the frame, and a guide limiting part between the lens cover and the frame for guiding the lens cover to the installation position and limiting lateral movement of the lens cover relative to the frame. The guide limiting part includes a mating protrusion on the frame and a recess on the lens cover for engaging with the mating protrusion.

[0007] Using the above solution, when assembling the lens cover and frame, simply align the groove on the lens cover with the mating protrusion on the frame and press them together until they are in contact. Then, push the lens cover to guide it to slide until the hook part mates with the frame, thus completing the installation. Compared with existing vision correction glasses, the guide and limiting part can quickly locate the installation position of the lens cover, reducing the time required for installation and simplifying the installation steps. When disassembling, the lens cover can be pushed off the frame from the opposite direction of the hook. Therefore, the lens cover of the vision correction glasses in this solution is convenient to install and remove.

[0008] Preferably, the hook component includes a horizontally protruding abutment section at one end of the lens cover towards the lens frame and a vertically downward protruding hook section at the end of the abutment section, with the lens frame snapped between the hook section and the groove and abutting against the abutment section.

[0009] With the above solution, after the lens case is installed, its lateral movement is limited by the fit between the protrusion and the groove. During the turning process, the positional offset of the lens case relative to the frame will be greatly reduced. Therefore, the hook component and the frame do not need to generate friction through a tight fit to limit the lateral movement of the lens case. When disassembling, no large pushing force needs to be applied to the lens case, thereby reducing the difficulty of disassembly. Thus, the guide and limiting part increases the stability of the fit between the lens case and the frame while reducing the difficulty of disassembly and assembly, making the disassembly and assembly of the lens case very convenient.

[0010] Preferably, the lens cover is provided with an anti-deflection structure to prevent the lens cover from flipping over with the edge of the abutment section as a fulcrum.

[0011] Preferably, the anti-deflection structure includes abutment strips extending along the edge of the lens cover on both sides of the abutment section.

[0012] With the above solution, the abutment section is relatively short, and the lens cover may become crooked during installation due to uneven pressure on both sides. However, in this solution, the lens cover is installed so that the edge of the frame abuts against the abutment strip, which can effectively reduce the possibility of the lens cover becoming crooked.

[0013] Preferably, the frame is provided with an auxiliary limiting structure to increase the resistance to the lens cover detaching from the frame.

[0014] Preferably, the auxiliary limiting structure includes magnets embedded on the opposite end faces of the frame and the lens cover.

[0015] With the above solution, when the lens cover and the frame are fitted together, the magnets on both sides attract each other, which increases the stability of the lens cover when fitted with the frame and prevents it from detaching from the frame from the opposite direction of the hook component. Moreover, this fitting method will not cause wear to the structure on the lens cover and the frame.

[0016] Preferably, the first lens includes an upper optical zone for distance vision and a lower optical zone for near vision.

[0017] Preferably, the second lens is made of a non-transparent material.

[0018] Preferably, the upper part of the second lens is provided with a first light-transmitting structure, which includes a number of through holes opened on the second lens, the number of which is 3 to 30.

[0019] Preferably, the lower half of the second lens is provided with a second light-transmitting structure, which is a through groove.

[0020] The above solution takes into account that most users of the vision correction glasses in this solution are children or students who are wearing glasses for the first time. When using the first lens alone, incorrect wearing habits may lead to poor myopia control. Therefore, this solution uses the light-transmitting structure on the second lens to correct the way the glasses are worn: the second lens is only used in conjunction with the first lens during class. The first lens is a bifocal lens, and the upper light area is used to see close objects, such as the blackboard. Due to the perspective principle that objects appear larger when closer and smaller when farther away, the image height of the content on the blackboard is relatively small, and it can easily pass through the aperture on the second lens. The lower light area is suitable for close-range vision, such as reading or writing. The reader can see the book through the slot on the second lens. If the glasses are worn incorrectly at this time, for example, if the wearer wears the glasses on a low position on the bridge of the nose for reading or writing, the upper light area of ​​the first lens is facing the eyes, and the aperture restricts the angle of light entering the eyes, preventing the wearer from seeing the entire content on the page by moving their eyes. This forces the wearer to realize that the glasses are worn incorrectly and actively adjust the position of the glasses. This combination method can effectively correct the incorrect way of wearing glasses.

[0021] This utility model, by adopting the above technical solution, has significant technical effects:

[0022] 1. When assembling the lens cover and frame in this solution, simply align the groove on the lens cover with the mating protrusion on the frame and press them together until they are in contact. Then, push the lens cover to guide it to slide until the hook part mates with the frame, thus completing the installation. Compared with existing vision correction glasses, the guide and limiting part can quickly locate the installation position of the lens cover, reducing the time required for installation and simplifying the installation steps. When disassembling, the lens cover can be pushed off the frame from the opposite direction of the hook. Therefore, the lens cover of the vision correction glasses in this solution is convenient to install and remove.

[0023] 2. After the lens case is installed, its lateral movement is limited by the fit between the protrusion and the groove. When wearing glasses, making left and right head movements will not change the position of the lens case. Therefore, the hook part and the frame do not need to generate friction through a tight fit to limit the lateral movement of the lens case. When disassembling, no large pushing force is required on the lens case, thus reducing the difficulty of disassembly. Therefore, the guide limit part increases the stability of the fit between the lens case and the frame while reducing the difficulty of disassembly and assembly, making the disassembly and assembly of the lens case very convenient.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] Example

[0034] A type of vision correction glasses, based on Figure 1 , 2 As shown, the glasses include a frame 1, with temples 2 on both sides of the frame 1. A first lens 3 is disposed inside the frame 1, the first lens 3 including an upper optical zone 31 for distance vision and a lower optical zone 32 for near vision. A lens cover 4 is detachably disposed on the frame 1, and a second lens 5 is disposed inside the lens cover 4. The second lens 5 is made of a non-transparent material, and the upper half of the second lens 5 has several through holes 51, the number of which is 3 to 30. Figure 2 , 3 As shown, in this embodiment, eight through holes 51 are provided, and the lower half of the second lens 5 is provided with a second light-transmitting structure, which is a through groove 52.

[0035] The lens case 4 is equipped with a hook component that allows the lens case 4 to be attached to the lens frame 1, according to Figure 5 , 7 As shown, the hook component includes a horizontally protruding abutment section 8 at one end of the lens cover 4 towards the lens frame 1, and a vertically downward protruding hook section 9 at the end of the abutment section 8. The lens frame 1 is engaged between the hook section 9 and the groove 7 and abuts against the abutment section 8. A guide limiting part is provided between the lens cover 4 and the lens frame 1 to guide the lens cover 4 to the installation position and limit the lateral movement of the lens cover 4 relative to the lens frame 1. Figure 3 , 5 As shown, the guide limiting part includes a mating protrusion 6 protruding on the frame 1 and a groove 7 recessed on the lens cover 4 that can fit with the mating protrusion 6.

[0036] The lens cover 4 is provided with an anti-rotation structure to prevent the lens cover 4 from flipping over with the edge of the abutment section 8 as the fulcrum. Figures 4-7 As shown, the anti-deflection structure includes abutment strips 11 extending along the edge of the lens sleeve 4 on both sides of the abutment section 8.

[0037] The frame 1 is provided with an auxiliary limiting structure to increase the resistance to the lens sleeve 4 detaching from the frame 1, according to Figure 2 , 4 As shown, the auxiliary limiting structure includes magnets 10 embedded on the opposite end faces of the frame 1 and the lens cover 4.

[0038] Referring to the above structure, combined with Figures 1-7In this solution, when assembling the lens cover 4 with the frame 1 in a vision correction eyeglass, simply align the groove 7 on the lens cover 4 with the mating protrusion 6 on the frame 1 and press them together until they are in contact. Then, push the lens cover 4 to guide it to slide until the hook part mates with the frame 1, thus completing the installation. Compared with existing vision correction eyeglasses, the guide limiting part can quickly locate the installation position of the lens cover 4, reducing the time required to install the lens cover 4 and simplifying the installation steps. When disassembling, the lens cover 4 can be pushed from the opposite direction of the hook holding the frame 1 to detach it from the frame 1. Therefore, the lens cover 4 of the vision correction eyeglass in this solution is convenient to install and disassemble.

[0039] After the lens case 4 is installed, its lateral movement is limited by the engagement of the protrusion 6 and the groove 7. During the rotation process, the positional offset of the lens case 4 relative to the frame 1 will be greatly reduced. Therefore, the hook part and the frame 1 do not need to generate friction through a tight engagement to limit the lateral movement of the lens case 4. When disassembling, it is not necessary to apply a large pushing force to the lens case 4, thereby reducing the difficulty of disassembly. Therefore, the guide and limiting part increases the stability of the engagement between the lens case 4 and the frame 1 while reducing the difficulty of disassembly and assembly, making the disassembly and assembly of the lens case 4 very convenient.
