Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spectacle lenses, and in particular to a spectacle lens for inhibiting the elongation of the eye axis. BACKGROUND

[0002] At present, the common myopia correction methods on the market include wearing ordinary glasses, contact lenses and orthokeratology lenses; however, most of these methods can only correct vision and cannot effectively control the development of myopia; in recent years, with the deepening of the research on eye optics, defocus lenses as a new type of myopia prevention and control means have gradually attracted attention, and the defocus lenses change the visual imaging process of the eye by designing specific defocus areas on the lenses to make peripheral light rays image in front of or behind the retina, thereby affecting the growth of the eye axis.

[0003] The existing defocus lenses are fixed in the frame by traditional clamping or adhesive bonding, which makes the lenses easily fall out of the frame when the glasses are bumped, or the lenses are inconvenient to disassemble for cleaning.

[0004] A micro-transmission defocus lens is disclosed in a Chinese patent (authorized publication number CN221572955U), which can realize quick docking of the lens and the frame through the butt joint of the protrusion and the built-in slot, and can improve the connection stability of the lens and the frame through the connection of the screw, and is more stable than the clamping method.

[0005] However, it has certain disadvantages: the lens and the frame are fixed together by screwing the screw into the protrusion, which requires special tools when disassembling the lens and the frame, is inconvenient to operate at any time, and the screw is exposed to the outside and is prone to rust during long-term use, which makes it difficult to disassemble the screw, thereby making it more difficult to disassemble the lens and the frame; in summary, the fixing method of the lens and the frame needs to be optimized.

[0025] The left and right two sides surfaces of defocus lens body 1 are all provided with docking mechanism 6, docking mechanism 6 includes docking seat 7, docking seat 7 is fixedly connected on the side surface of defocus lens body 1, and docking seat 7 is embeddedly connected to the front surface of frame 2, the front surface of docking seat 7 is slidably connected with push plate 8 in horizontal direction, the left and right two ends of push plate 8 are all fixedly connected with sliding plate 9, and sliding plate 9 is embeddedly slidably connected to the front end of docking seat 7, the inside of docking seat 7 is provided with docking piece 11, docking piece 11 includes docking plate 12, the four corners of docking plate 12 are all movably connected with sliding rod 13, the end of sliding rod 13 is fixedly connected to the inside left and right two sides surfaces of docking seat 7, push block 14 is fixedly connected to the front surface of docking plate 12, the front end of push block 14 is fixedly connected to the rear surface of push plate 8 at the end position away from defocus lens body 1, spring 15 is fixedly connected to the inside one side surface of docking seat 7 on the side surface of docking plate 12 close to defocus lens body 1, docking block 16 is fixedly connected to the side surface of docking plate 12 away from defocus lens body 1, and docking block 16 movably penetrates the side surface of docking seat 7 away from defocus lens body 1, and docking block 16 is embeddedly connected to the inside of frame 2;

[0026] The front surface and the inside surface of frame 2 jointly form first recess for accommodating docking seat 7;Second recess for accommodating docking block 16 is formed on the side surface of first recess away from the inside surface of frame 2;

[0027] By clamping the butt joint block 16 in the second groove in the frame 2, the defocus lens body 1 is facilitated to be fixed in the frame 2; the push plate 8 is pushed in the direction close to the defocus lens body 1, the butt joint block 16 is driven to retract into the butt joint seat 7, and the defocus lens body 1 is facilitated to be taken out;

[0028] The front end of the butt joint seat 7 is provided with a first sliding hole, and the left and right ends of the first sliding hole are communicated with second sliding holes; the push plate 8 slides in the first sliding hole; in the initial state, the push plate 8 is located in the end of the first sliding hole far away from the defocus lens body 1, most of the slide plate 9 close to the defocus lens body 1 is located in the first sliding hole, only a small part is located in the second sliding hole, and the slide plate 9 far away from the defocus lens body 1 is completely located in the second sliding hole.

[0031] The multi-point defocus area 4 comprises a plurality of microlenses or annular micro-columnar lenses, which are arranged in a specific manner, so that the light entering the eye forms myopic defocus on the retina; specifically, the microlenses or micro-columnar lenses focus the light in front of the retina, thereby giving the retina a forward stimulation signal, and this design helps to inhibit the growth of the eye axis, because the forward stimulation signal received by the retina is considered to slow down the growth rate of the eyeball;

[0032] The peripheral area 5 further enhances the inhibitory effect on the growth of the eye axis, by reducing the negative power or increasing the positive power of the peripheral area, so that when the eye looks at a near object, the light of the peripheral visual field will also be focused in front of or near the retina, thereby enhancing the defocus effect.
