[0001] The utility model relates to myopia glasses technical field especially relates to a myopia prevention and control glasses. BACKGROUND

[0002] The Chinese patent with the publication number CN209215765U discloses a composite type prevention and treatment myopia three-purpose glasses, the glasses include frame parts and temple parts, the frame parts include the first connecting piece and the inner frame symmetrically arranged on the both sides of the first connecting piece, the first connecting piece is detachably provided with the second connecting piece, the second connecting piece is symmetrically provided with the outer frame on the both sides, the second connecting piece and the first connecting piece are respectively fixedly provided with the magnet that can attract each other, a pair of inner lenses are fixedly arranged on the inner frame, the inner lenses are myopia lenses, a pair of outer lenses are fixedly arranged on the outer frame, the outer lenses are hyperopia lenses, which can prevent and treat low myopia development and treat pseudomyopia.

[0003] The eye is generally divided into three situations, looking at the near view, looking at the distance and close distance, when wearing the above glasses, the wearer needs to select different lens collocation mode according to the eye scene, for example, when reading and writing, the inner frame and the outer frame are used at the same time, the hyperopia adjustment function of the outer lens is used to slow down the eye fatigue; when looking at the near view, only the inner frame is used, the myopia adjustment function of the inner lens can help the wearer to see the object in the near distance, therefore, the outer frame of the above glasses needs to be frequently disassembled and assembled, the outer frame and the inner frame are positioned by magnetic attraction, which is very convenient to disassemble and assemble, but the stability between the outer frame and the inner frame is poor, when rotating the head or the fingers touch the outer frame, the position of the outer frame will be deviated, when the deviation exceeds the magnetic field range of the magnet, the inner frame loses the attraction to the outer frame, which may cause the outer frame to fall off, therefore, the composite type prevention and treatment myopia three-purpose glasses still has room for improvement in the stability of the inner frame and the outer frame. UTILITY MODEL CONTENTS

[0004] In view of the poor stability of the inner frame and the outer frame of the existing myopia prevention and control glasses, the utility model aims at providing a myopia prevention and control glasses with better stability and less disengagement when the inner frame and the outer frame are matched.

[0005] In order to solve the above technical problems, the utility model solves them by the following technical schemes:

[0006] A myopia prevention and control glasses, including frame part, the frame part includes the main frame and the vice frame that can be detachably arranged on the main frame, the guide installation part that can guide the vice frame to be connected with the main frame is arranged between the main frame and the vice frame, the vice frame can only be separated from the main frame along the guide installation part, and the opposite side of the main frame and the vice frame is positioned by the magnetic attraction part when the main frame and the vice frame are overlapped.

[0007] By the above scheme, the guide mounting component can guide the auxiliary frame to the position matched with the main frame, and play a role of pre-positioning, and after the two are matched, the auxiliary frame can only be separated from the main frame along the guide mounting component, and the magnetic force of the magnetic attraction component can drive the auxiliary frame to be attracted to the inner frame, thereby limiting the auxiliary frame from being separated from the inner frame in the above direction, so that the guide mounting component in the scheme can reduce the offset or deflection of the auxiliary frame relative to the inner frame when the wearer rotates the head or touches the auxiliary frame with fingers, thereby reducing the risk of the auxiliary frame falling from the main frame and increasing the stability of the glasses.

[0008] Preferably, the main frame comprises a first connecting piece and first frame pieces symmetrically arranged on both sides of the first connecting piece, and the auxiliary frame comprises a second connecting piece and second frame pieces symmetrically arranged on both sides of the second connecting piece, and the guide mounting component is arranged between the first connecting piece and the second connecting piece.

[0009] Preferably, the second connecting piece comprises a connecting bridge and connecting wings arranged in parallel and staggered with respect to the connecting bridge at both ends of the connecting bridge, and the connecting bridge and the connecting wings are connected by a connecting plate, and the end of the connecting wing is fixedly connected with the second frame piece, and the included angle between the connecting plate and the connecting bridge is greater than 90°.

[0010] By the above scheme, the auxiliary frame must be separated from the main frame along the direction of the guide mounting component, and when the auxiliary frame is removed, people generally fix the main frame with one hand, and the nails of the other hand are inserted into the first connecting piece to generate a gap between the first connecting piece and the second connecting piece, and then the nails and fingers exert force to make the second connecting piece rise to be out of the magnetic force range of the magnetic attraction component, and then the second connecting piece is pinched to take away the auxiliary frame, which can avoid the fingers from dirtying the lenses, but in the above process, the force exerted by the nails on the second connecting piece must be greater than the magnetic force to make the second connecting piece rise, and the magnetic force disappears at the moment when the second connecting piece is out of the magnetic force range, at which time people must quickly react to pinch the second connecting piece with the fingers to prevent the auxiliary frame from falling, but in order to reduce the weight of the glasses, the second connecting piece is designed to be relatively small in structure, and the force receiving area is small when pinching, so that the auxiliary frame is easily lost due to uneven force, but in the scheme, when the fingers pinch the connecting bridge, the included angle between the connecting plate and the connecting bridge increases the contact area with the fingers, which makes it more convenient for people to pinch the connecting bridge and reduces the probability of failure; if the failure still occurs and the connecting bridge tilts to the side of the fingers and falls, the connecting plate can block the falling effect, which gives the fingers time to adjust the pinching action, further reduces the probability of failure, and makes the process of removing the auxiliary frame simpler and more successful.

[0011] Preferably, the guide mounting component comprises a plug-in rod protruding from the lower end surface of the connecting bridge and a plug-in slot provided on the upper end surface of the first connecting piece for the plug-in rod to be inserted, and the cross section of the plug-in rod and the plug-in slot is non-circular.

[0012] With the above scheme, the plug-in rod can be guided to be inserted into the slot, the slot limits the transverse movement of the plug-in rod, and the cross sections of the two are designed as non-circular shapes to prevent the sub-frame from being deflected with the plug-in rod as the center.

[0013] Preferably, an inverted bevel is arranged at the upper end edge of the first connecting piece.

[0014] With the above scheme, when the sub-frame is removed, the fingers of a person can enter the gap between the inverted bevel and the connecting bridge and gradually lift the second connecting piece, and it is no longer necessary to force the second connecting piece and the first connecting piece to be pried apart to be lifted, which not only plays a labor-saving role, but also avoids the situation that the sub-frame is popped out due to excessive force without timely force recovery, thereby simplifying the difficulty of disassembling the sub-frame.

[0015] Preferably, a first lens is fixedly arranged on the main frame, and the first lens is a myopia lens.

[0016] Preferably, an optical structure for relaxing the eyes is arranged on the first lens.

[0017] Preferably, the first lens comprises a defocus area and a central area, the optical structure comprises a plurality of first defocus points distributed at the defocus area and a plurality of second defocus points distributed at the central area, and the distribution density of the second defocus points is less than the distribution density of the first defocus points.

[0018] With the above scheme, for the existing defocus lens, the defocus area generally adopts a point diffusion technology to artificially scatter the light entering the eyes to be out of focus, and finally a blurred image is formed, the soft scattered light reduces the retinal contrast, reduces the elongation signal emitted by the machine to the eyes from the high-contrast signal detected by the retinal photoreceptor cells, thereby delaying the growth of the eye axis and delaying the deepening of myopia, and the central area is a completely transparent vision correction area; unlike the existing defocus lens, the central area of the second lens in the present scheme also adopts the above optical structure, but the distribution density of the second defocus points is less than that of the first defocus points, when the central area is used to look at a close-up, the blur degree of the close-up image in the central area will be less than that in the defocus area, and when looking at a distant view, the second defocus point distribution will also reduce the influence on the imaging, so that the distant view is relatively clear, therefore, the wearer can obtain the effect of clear distant view and mild blur close-up through the central area, and the vision line repeatedly switches between the distant view and the close-up, which is relative to the repeated adjustment of the eyes between the relaxed and tense states, thereby playing a training effect, and the training can effectively prevent or delay the growth of myopia.

[0019] Preferably, a second lens is fixedly arranged on the sub-frame, and the second lens is a prism-transparency combined lens.

[0020] Adopting the above scheme, the prism-transmission combined lens can change the direction of light entering the eye, reduce the convergence requirement of the glasses when using the eyes at a short distance, relieve the effect of intraocular muscle tension, and reduce the accommodation fatigue.

[0021] The utility model discloses a guide installation part can guide the vice frame to the position with the main frame cooperation, play the role of preposition, when the cooperation, vice frame can only along guide installation part separate the main frame, and the magnetic force of magnetic attraction part can drive vice frame and inner frame mutual attraction, limited vice frame from the direction separate inner frame, therefore, when the wearer rotates the head or touches vice frame with the finger, the guide installation part in this scheme can reduce the offset or deflection of vice frame relative to inner frame, reduces the risk of vice frame from the main frame drop, increases the stability of glasses.
