Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method of processing the compound lens of the present invention is described below with reference to fig. 1 to 3. Referring to fig. 1, the present invention provides a method for processing a compound lens, including the following steps:
s10, selecting a first lens and a second lens according to the ophthalmic prescription and the requirement of a user;
s20, coating optical cement on the surface of the first lens in a preset shape, and covering the second lens on the first lens to enable the first lens and the second lens to be glued to form a lens group;
and S30, placing the lens group in a carrier.
In the sealing technique of the compound lens, optical glue is generally coated on the surface of one lens, and then the two lenses are attached to each other, so as to achieve a good sealing effect. However, the optical cement easily affects the imaging effect of the center of the lens; in some techniques, optical cement is coated around two assembled lenses, so that the imaging effect of the lenses is not affected, but the optical cement around the lenses is easily peeled off and lost due to the influence of corrosion such as friction or sweat, and the sealing effect is affected. According to the technical scheme provided by the invention, the optical cement is coated along the preset shape, and then the two lenses are combined and sealed, so that on one hand, a good sealing effect is achieved, and on the other hand, the imaging effect of the lenses is not influenced.
In the first embodiment of the processing method of the compound lens provided by the present invention, after S10, "selecting the first lens and the second lens according to the ophthalmic prescription and the user' S requirement" further includes:
and S100, determining the processing shapes of the first lens and the second lens according to the carrier.
The lenses are generally a combination of corrective lenses, non-corrective lenses, and auxiliary (functional) lenses. Corrective lenses are used to correct ametropia, such as positive sphere, negative sphere, cylinder, etc.; non-corrective lenses such as polarizers, dyed sheets, color-changing sheets, filters, brightness enhancement sheets, etc.; auxiliary (functional) such as multifocal, progressive, ring focus, defocus, prism, AR/VR lenses, etc. By selecting appropriate lenses for combination, a compound lens suitable for ophthalmic prescriptions can be formed. After selecting the appropriate first lens and second lens according to the correction requirement and the use requirement of the user, the user can select the carrier, such as a spectacle frame, according to the own requirement. Different spectacle frames have different shapes, such as circular spectacle frames, square spectacle frames, etc., and the machining shape of the first lens and the second lens needs to be determined according to the shape of the carrier, for example, a circular spectacle frame needs to machine both lenses into a circle to match the spectacle frame. It should be noted that, in some cases, more than two lenses may be selected, for example, a third lens, and the third lens is processed in the same way as the first lens and the second lens, which is not limited by the present invention.
Further, S20, coating an optical adhesive on the surface of the first lens in a predetermined shape, and covering the second lens on the first lens to bond the first lens and the second lens to form a lens assembly includes:
s21, coating optical cement on the surface of the first lens according to the processing shape;
s22, covering the first lens with the second lens;
and S23, waiting for the optical cement to be solidified to form a lens group.
After the processing shapes of the first lens and the second lens are selected, coating the optical cement on the surface of the first lens according to the processing shapes, and covering the second lens on the first lens to finish the sealing of the lenses. Therefore, the area of the first lens and the second lens in the processing shape is effectively sealed, and a sealed cavity is formed, so that the subsequent processing is facilitated. It should be noted that, in the process of coating the optical cement, the diameter of the inner area of the optical cement needs to be slightly smaller than that of the processing shape, so that when the cutting lens is processed, the optical cement cannot be cut off, and the sealing effect is not affected. It should be noted that the sealed chamber is generally filled with air or vacuum, and the invention is not limited thereto.
It should be noted that the optical cement should have a high viscosity before being cured, so that the optical cement is easy to mold and can be cured into an annular rubber ring. The optical cement is preferably made of materials which are waterproof, non-irritant to human bodies, resistant to corrosion of sweat and the like, so that a sufficient sealing effect in the lens is guaranteed, and water mist cannot form and impurities cannot fall into the lens.
Further, before S30, "placing the lens group in the carrier", the method further includes:
s200, cutting the lens group along the processing shape;
s300, performing edge processing on the cut lens group according to the carrier;
s400, grinding the edge of the lens group.
In the first embodiment of the present invention, the sealant is coated on the original lens along the processing shape, and after the two lenses are combined, the lens assembly is cut along the processing shape to match the carrier. Due to the variety of types of carriers, when the carrier is a spectacle frame, the edges of the lens groups are processed according to the type of the frame, so that the lenses can be mounted in the spectacle frame. Spectacle frames are generally classified into full-rim, half-rim and rimless frames, for example, half-rim frames require a groove to be formed in the center of the periphery of the lens group, so as to insert nylon wires to fix the lens. At the moment, the required grooving depth is met, the optical cement width is correspondingly adjusted, and the sealing effect is prevented from being lost due to the grooving step. In addition, need polish the edge of lens group smoothly, form the fillet, avoid the user to cause the fish tail in the use.
In another embodiment of the present invention, after S10, "selecting the first lens and the second lens according to the ophthalmic prescription and the user' S requirement", the method further comprises:
s11, determining the processing shapes of the first lens and the second lens according to the carrier;
and S12, cutting the first lens and the second lens along the processing shape.
In this embodiment, the first lens and the second lens are cut along the processing shape and then sealed.
Further, S20, coating an optical adhesive on the surface of the first lens in a predetermined shape, and covering the second lens on the first lens to bond the first lens and the second lens to form a lens assembly includes:
s24, coating optical cement on the surface of the first lens along the edge of the first lens;
s25, covering the first lens with the second lens;
and S26, waiting for the optical cement to be solidified to form a lens group.
In addition, since the first lens and the second lens are cut, the optical adhesive is coated on the surface of the first lens along the edge of the first lens, and the first lens and the second lens are sealed and combined to form the lens assembly according to the method.
Further, before S30, "placing the lens group in the carrier", the method further includes:
s500, performing edge processing on the lens group according to the carrier;
s600, polishing the edge of the lens group.
As mentioned above, due to the variety of types of carriers, when the carrier is a spectacle frame, the edges of the lens groups are processed according to the type of frame, so that the lenses can be mounted in the spectacle frame. Spectacle frames are generally classified into full-rim, half-rim and rimless frames, for example, half-rim frames require a groove to be formed in the center of the periphery of the lens group, so as to insert nylon wires to fix the lens. At the moment, the required grooving depth is met, the optical cement width is correspondingly adjusted, and the sealing effect is prevented from being lost due to the grooving step. In addition, need polish the edge of lens group smoothly, form the fillet, avoid the user to cause the fish tail in the use.
The invention provides two embodiments of processing methods of a compound lens, wherein in the first embodiment, optical cement is coated on an untreated lens according to a processing shape, and cutting and edge processing are carried out after two lenses are combined; in the second embodiment, both the two lenses are cut according to the processing shape, then the optical cement is coated, and after the sealing is finished, the edge treatment is carried out. The user can select the appropriate method and steps according to the needs, which is not limited by the present invention.
Further, referring to fig. 2-3, in any embodiment, the coating width of the optical adhesive is 0.5mm-3mm, and the coating thickness is 0.2mm-2 mm. It should be noted that the width of the optical cement in the finished composite lens product is greater than 1mm, and the original coating width of the optical cement should be greater than 1mm in consideration of the cutting and polishing consumables when the optical cement is coated. In addition, the thickness of the optical cement needs to be less than 2mm, the optical cement with too thick thickness can cause the colloid to overflow, the sealing quality and appearance are affected, and a user can select the proper colloid thickness to seal within the range.
Furthermore, when the second lens covers the first lens, the optical centers of the first lens and the second lens are coaxial, so that an effective compound lens can be formed. In addition, it should be noted that, in order to ensure the sealing effect of the two lenses, the curvatures of the first lens and the second lens are similar or the same, so that the two lenses can be effectively attached to each other, and the sealing effect is improved.
Specifically, S30, "placing the lens group in the carrier" includes:
s31, coating optical cement on the periphery of the lens group, and placing the lens group in a carrier after the optical cement is solidified; and/or the presence of a gas in the gas,
and S32, placing a sealing rubber ring at the corresponding position of the carrier, and installing the lens group in the sealing rubber ring.
It should be noted that, during the process of performing the lens processing, the error may cause the installation between the compound lens and the carrier to be not tight; or the size difference between the compound lens and the mounting frame is caused by the design tolerance of the carrier. In the technical scheme provided by the invention, referring to fig. 3, the joint of the composite lens and the carrier can be coated with optical cement, the optical cement plays a role in material increase of the composite lens, and the dried optical cement can assist in increasing the boundary of the composite lens so that the composite lens is tightly attached to the carrier. Of course, reference may also be made to goggles, swimming goggles, etc., where the sealing rubber ring is prevented at the carrier position, on the one hand to compensate for material tolerances and on the other hand to provide a further sealing effect for the compound lens, which is not limited by the present invention.
As described above, the types of the first lens and the second lens are various, and the lens needs to be selected according to the vision condition of the user and other conditions when the user fits the glasses. In some cases, a profiled lens with an uneven surface, such as a fresnel lens, may be used. Under this condition, fresnel lens's working face (fresnel surface) generally inwards (rubber coating and another lens laminating), so can make fresnel surface not show outside, under the prerequisite that reaches good formation of image effect, also can play the guard action to fresnel surface, prevent frostbite or deposition, improve the life of lens.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
