Description

Optical lens device with polarizing film and its manufacturing method

The present invention relates to an optical lens device with a polarization film and a manufacturing method thereof; in particular, to an optical lens device with a heat setting treatment polarization film and a manufacturing method thereof.

Regarding the multifunctional optical lens device for learning tools with anti-fog function and its manufacturing method, for example: US Patent Publication No. US-10259744 "PROCESS FOR PRODUCING AN OPTICAL GLASS WITH AN ANTI-FOG COATING" invention patent, which discloses a multifunctional optical lens with anti-fog function and its manufacturing method.

Figure 1 shows a schematic diagram of the structure of the multifunctional optical lens device for playing equipment with anti-fog function in U.S. Patent Publication No. US-10259744. Referring to Figure 1, the multifunctional optical lens with anti-fog function in the aforementioned patent No. US-10259744 includes a lens body, a front lens surface, a front surface anti-fog layer and a rear lens surface, and the front surface anti-fog layer is an anti-fog coating layer, and the front surface anti-fog layer is a hydrophilic coating layer with Si-C bonds.

Please refer to FIG. 1 again. In terms of structure, the front surface antifogging layer of the aforementioned patent No. US-10259744 is formed on the front lens surface of the lens body to reduce or minimize the contact angle of water droplets attached to the front surface antifogging layer and prevent clouding from occurring on the front lens surface of the lens body.

However, the aforementioned patent No. US-10259744 does not have any polarizing layer, heat-set polarizing layer, or similar polarizing layer or polarizing film on the rear lens surface of the lens body. Therefore, the rear lens surface of the lens body (e.g., surfaces with various curvatures or spherical surfaces) often leads to various disadvantages that it is difficult to accurately shape the polarizing layer or polarizing film.

Another commonly used anti-fog optical lens device, for example: the invention patent of the Republic of China Patent Publication No. TW-I754919, "Multifunctional anti-fog optical lens device", discloses a multifunctional anti-fog optical lens device. The multifunctional anti-fog optical lens device includes an optical substrate layer, a functional optical layer and an anti-fog layer, and a first front surface and a second rear surface are arranged on the optical substrate layer.

As mentioned above, the functional optical layer of the aforementioned patent No. TW-I754919 is formed on the second rear surface of the optical substrate layer, and the functional optical layer is used to provide an optical functionality on the second rear surface of the optical substrate layer. The antifogging layer is formed on the second rear surface of the optical substrate layer, and the antifogging layer is used to provide an antifogging property on the second rear surface of the optical substrate layer, so that the antifogging layer on the second rear surface of the optical substrate layer can prevent fogging due to various factors.

However, although the antifogging layer of the aforementioned patent No. TW-I754919 is formed on the second rear surface of the optical substrate layer to prevent fogging caused by various factors, it does not disclose how to simplify the antifogging layer formed on the second rear surface of the optical substrate layer in terms of the manufacturing method to reduce the complexity of the overall manufacturing process.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the invention patent of the Republic of China Patent Publication No. TW-I588516 "Manufacturing method of anti-fog lens and anti-fog lens" discloses an anti-fog lens. The anti-fog lens comprises a lens, a PC material layer, a PC film and an anti-fog film, and the PC film and the anti-fog film are first bonded to each other with an optical glue to form a composite PC film and anti-fog film assembly, and then the lens and the composite PC film and anti-fog film assembly are injection molded with a PC material to form a cured molded body.

However, the solidified molded body of the aforementioned patent No. TW-I588516 includes the lens, PC material layer, PC film and anti-fog film, that is, it forms a multi-layer solidified molded body, and its manufacturing method requires optical adhesive bonding process and injection molding process to be performed separately, so it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog and color-changing lens" No. TW-M542774 of the Republic of China, which discloses an anti-fog and color-changing lens. The anti-fog and color-changing lens includes a lens body, an anti-fog sheet and a color-changing sheet, and the lens body has a front surface and a rear surface, and the anti-fog sheet is formed on the rear surface of the lens body, and the color-changing sheet is formed on the front surface of the lens body.

As mentioned above, the antifog sheet of the aforementioned patent No. TW-M542774 is composed of a first PC film and an antifog film bonded to each other with an optical adhesive to form a first adhesive assembly, and the color-changing sheet is composed of a photochromic material sandwiched between a second PC film and a third PC film to form a second multi-layer assembly.

However, the lens body, anti-fog sheet and color-changing sheet of the aforementioned patent No. TW-M542774 are combined with several PC films to form the first adhesive assembly and the second multi-layer assembly. In this way, the manufacturing method needs to perform optical adhesive bonding and injection molding operations respectively. Therefore, it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog Lens" No. TW-M544409 of the Republic of China, which discloses an anti-fog lens. The anti-fog lens includes a lens body, a plastic film, a UV adhesive layer and an anti-fog film, and the lens body has a front surface and a rear surface.

As mentioned above, the UV adhesive layer of the aforementioned patent No. TW-M544409 is firstly attached to the plastic film and the anti-fog film, and then the UV adhesive layer is irradiated with ultraviolet light to glue the plastic film and the anti-fog film together to form an anti-fog sheet body, and the lens body is injection molded on the surface of the plastic film of the anti-fog sheet body.

However, the manufacturing method of the lens body, plastic film, UV adhesive layer and anti-fog film of the aforementioned patent No. TW-M544409 requires UV gluing process, UV light curing process and injection molding process respectively. Therefore, it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure, and its UV light curing process is easy to affect the quality of the anti-fog lens.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog lens and goggle device" in the Republic of China Patent Publication No. TW-M552108, which discloses an anti-fog lens. The anti-fog lens includes a protective layer and an anti-fog layer, and the protective layer of the anti-fog lens has a front surface and a rear surface.

As mentioned above, the protective layer of the aforementioned patent No. TW-M552108 is selected as a PC layer, and the antifogging layer is selected as a PET layer or a TAC layer, and the antifogging layer is directly selected to be bonded to the rear surface of the protective layer by injection molding or hot pressing, that is, there is no optically functional structural layer between the protective layer and the antifogging layer or on the combined layer.

However, although the antifogging layer of the aforementioned patent No. TW-M552108 is directly bonded to the rear surface of the protective layer by injection molding or hot pressing, the manufacturing method does not further disclose how to simplify the formation of the antifogging layer on the rear surface of the protective layer to reduce the complexity of the overall manufacturing process.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog Thin Frame Snow Goggles" No. TW-M553811 of the Republic of China, which discloses an anti-fog thin frame snow goggles. The anti-fog thin frame snow goggles include a lens body, and the lens body includes a light-transmitting layer, a front anti-fog layer, a filter layer and a rear anti-fog layer, and the lens body has a front surface and a rear surface.

As mentioned above, the front antifog layer and filter layer of the aforementioned patent No. TW-M553811 are located on the front surface of the lens body by dip-coating, and the rear surface is located on the rear surface of the lens body, that is, there is no optically functional structural layer on the rear surface of the lens body.

However, although the front antifogging layer of the aforementioned patent No. TW-M553811 is directly bonded to the front surface of the lens body by dip coating, the manufacturing method does not further disclose how to simplify the formation of any antifogging layer on the rear surface of the lens body to reduce the complexity of the overall manufacturing process.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog Photochromic Lens" No. TW-M583056 of the Republic of China, which discloses an anti-fog photochromic lens. The anti-fog photochromic lens includes a lens, a first transparent plastic sheet, a photochromic material layer, a second transparent plastic sheet and an anti-fog film, and the lens has a front surface and a rear surface.

As mentioned above, the photochromic material layer of the aforementioned patent No. TW-M583056 is sandwiched between the first transparent plastic sheet and the second transparent plastic sheet, and the first transparent plastic sheet, the photochromic material layer and the second transparent plastic sheet are glued to form a photochromic composite layer, and the photochromic composite layer and the antifogging film are further glued to form an antifogging color-changing composite sheet.

However, the first transparent plastic sheet, the photochromic material layer and the second transparent plastic sheet of the aforementioned patent No. TW-M583056 are glued together with the anti-fog color-changing composite sheet to form the lens by injection molding. In the manufacturing method, multiple gluing operations and injection molding operations are required. Therefore, it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure.

Obviously, the conventional optical lens devices and their manufacturing methods of the aforementioned U.S. Patent No. US-10259744, Republic of China Patent Publication No. TW-I754919, No. TW-I588516, No. TW-M542774, No. TW-M544409, No. TW-M552108, No. TW-M553811 and No. TW-M583056 are bound to have a need for further improvement in order to provide a composite layered optical lens device.
