Eyeglass lens improved structure

The present invention is an improved structure of an eyeglass lens, and particularly relates to an improved structure of an eyeglass lens which can ensure the clarity of the eyeglass lens and reduce the light reflectance.

The eye is the most important visual organ for us to obtain various information. If the eyesight has problems, such as myopia, presbyopia, hyperopia, astigmatism, etc. generated by eyeball lesions, in addition to seeking medical help, the most convenient and effective way is to borrow Eyesight correction is performed by wearing glasses.

Conventionally known glasses have a basic structure in which a middle beam and a ear frame (frameless glasses) are assembled on a pair of lenses, or a pair of lenses are assembled in a frame of a spectacle frame to form a pair of glasses. Wherein, the lens is effective in correcting vision. If the quality of the spectacle lens does not conform to the standard, such as the wear of the lens surface, or the lens material clarity is too low or the light reflectance is too high, the finished glasses are not only easy. This can cause discomfort to the wearer and cause further eye damage.

In terms of manufacturing materials, known spectacle lenses include glass lenses made of glass material, and resin lenses formed by resin materials and commonly known as safety lenses in the industry. Among them, the glass lens has the advantages of high definition, low light reflectivity and low wear resistance, but the glass material also has the disadvantages of being hard, too heavy and fragile, and has safety concerns. Resin lenses are lighter, harder and less prone to breakage, and are more suitable for glass lenses than glass lenses. However, the surface of resin lenses is easily exposed by foreign objects, so it is generally processed on the surface of resin lenses through multiple layers of film. For protection, such a multilayer film can improve the surface wear of the resin lens, but also increases the labor cost of manufacturing the resin lens.

In view of this, the present invention provides an improved structure of the spectacle lens.

That is to say, the main purpose of the creation is to provide a single layer of film processing as lens protection to ensure the rigidity and sharpness of the lens surface and reduce the light reflectivity (reflective). Improved structure of the eyeglass lens.

A further object of the present invention is to provide a lens which can add titanium trioxide (Ti3O5) to a single layer of protective film material to make the protective film layer more dense and uniform, and greatly improve the fixing stability of the protective film layer on the surface of the lens. Improved lens construction.

In order to achieve the above objectives, the present invention employs the following technical means.

The improved configuration of the spectacle lens of the present invention comprises a combination of a lens and a protective film layer bonded to the surface of the lens.

The lens is circular and can be processed into a spectacle lens by cutting, so as to mount the beam and the ear frame in the lens, or inside the two frames of the pair of glasses.

The protective film layer is a protective film layer which is formed by coating a surface of the lens with at least one layer of cerium oxide (SiO2) by a vacuum coating machine in advance to form an outer surface of the lens.

The cerium oxide (SiO2) film has high transparency, high definition and very low light reflectivity. The ruthenium dioxide film layer bonded to the surface of the lens can strengthen the surface rigidity of the lens and is not easily exposed by foreign matter. Therefore, the lens lens clarity and light reflectance can be ensured.

In actual manufacturing, the protective film layer may also be added with titanium trioxide (Ti3O5) in the ceria material, and the ceria film is made by using the relatively stable metal-like temperature-blocking property of titanium in the oxide. The film layer is denser and more uniform, so as to greatly improve the stability of the film layer and improve the optical properties and mechanical strength of the film layer.

The improved structure of the spectacle lens of the present invention has obvious advantages. For example, in the embodiment of the embodiment to be described later, if the spectacle lens is a glass lens, the surface of the cerium oxide (SiO2) film layer can effectively prevent the lens. Fragmentation improves the safety of the glass lens; if the lens lens is a resin lens, the surface of the cerium oxide (SiO2) film layer can effectively prevent the lens from contacting the foreign object and wear, and whether or not the glass is used. Lens or resin lens, this creation only needs to be processed as a single layer of protective film, which has the effect of traditional multi-layer film, which can reduce the manufacturing cost of the lens and achieve the intended purpose of this creation.

The construction and features of the preferred embodiment of the present work are further described in detail below with reference to the drawings.

Figure 5 is a partial cutaway view of the spectacle lens of Figure 4.

2 and 4, the improved eyeglass lens structure of the present invention comprises a combination of a lens 20 and a protective film layer 21 bonded to the surface of the lens 20.

The lens 20 is circular and can be processed into a spectacle lens by a cutting process, as shown in FIG. 3, so that the beam and the ear frame of the eyeglasses are assembled to form rimless glasses (not shown in this embodiment), or are installed in the lens. The inside of the two frames 11 of the pair of glasses 10 is as shown in Fig. 1.

The lens 10 shown in FIG. 1 includes a pair of frames 11 connected by a middle beam 12, two frames 11 for mounting the lens 20, and a nose pad 13 disposed inside the two frames 11. On the outside of the two frames 11, the ear frame 14 is connected via a pivot, respectively.

4 and 5, the protective film layer 21 is previously protected by a vacuum coating machine on the surface of the lens 20 by bonding at least one layer of cerium oxide (SiO2) film to form the outer surface of the lens. Film layer 21.

The cerium oxide (SiO2) film formed on the surface of the lens 20 by the vacuum coating machine has the characteristics of high transparency, high definition and extremely low light reflectivity, and the cerium oxide film layer 21 bonded to the surface of the lens can be used. The surface of the reinforced lens 20 is rigid and is not easily worn by contact with foreign objects, so that the clarity of the spectacle lens 20 can be ensured and the light reflectance can be lowered.

In actual manufacturing, the protective film layer 21 may also add trititanium pentoxide (Ti3O5) to the ceria material, and use the relatively stable metal-like temperature-blocking property of titanium in the oxide to make cerium oxide. The film layer of the film is more dense and uniform to greatly improve the stability of the film layer 21, and can improve the optical properties and mechanical strength of the film layer 21.

The improved configuration of the eyeglass lens of the present invention has obvious advantages: if the lens 20 of the lens 10 of the embodiment of Fig. 1 is a glass lens, the surface of the cerium oxide (SiO2) film layer 21 can be effectively prevented. The lens is broken, which improves the safety of the glass lens; if the lens 20 of the embodiment 10 in the first embodiment is a resin lens, the surface is deoxygenated. The cerium oxide (SiO2) film layer 21 can effectively prevent the lens 20 from being worn due to contact with foreign objects, and whether a glass lens or a resin lens is used, it is only required to be processed as a single layer, and has a conventional multilayer. The effect of the film can reduce the manufacturing cost of the spectacle lens and achieve the intended purpose of the present invention.

The improved lens structure of the present invention is coated on the surface of the lens 20 In combination with a layer of protective film 21, it has the effect of ensuring the clarity of the spectacle lens and reducing the light reflectivity, but in actual manufacturing, it can also be viewed on different occasions (such as on the spectacle lens of other materials). The coating process is combined to bond the majority of the film layer 21 to increase the structural strength of the lens 20 or to change the color of the lens 20.

On the lens 20 to which a layer of the protective film layer 21 has been combined, other differences can also be made. Type coating processing, such as AR coating, UV treatment, oil-proof coating treatment, etc., will not affect the original effect of ensuring the clarity of the spectacle lens and reducing the light reflectivity (reflective). .

In summary, this creation can achieve the expected function and purpose, and in detail It is obvious that those skilled in the art can implement this. However, the above embodiments are for illustrative purposes only, and all modifications of equivalent structures and similar modifications that do not depart from the spirit of the present invention are subject to the scope of this creation.
