Description

Technical Field

[0001] The utility model relates to the technical field of defocus lenses, and specifically relates to a composite film layer resin defocus lens. Background Art

[0002] Since adolescence is a stage of rapid physical development, and during the learning process, the eye use demand is very large, the eyeballs need to be adjusted frequently, and the extensibility is relatively large, it is relatively easy to form myopia. Due to wearing glasses for a long time, whether looking far or near, there is a habit of wearing glasses, which will inevitably cause eye disorders, cause excessive tension in the eyeballs, and result in a vicious cycle of continuous increase in glasses degrees.

[0003] The existing ordinary myopia glasses only meet the need of looking far, and are not suitable for the looking-far and writing habits of teenagers, and do not conform to the eye use mechanism of teenagers. When switching from looking far to looking near, the eye axis cannot keep up with the adjustment change speed, which will cause the object to be seen behind the eye axis. Repeating this many times will cause eye fatigue and further deepen the myopia degree.

[0004] For example, the Chinese authorized patent with the publication number CN 217821147 U (a composite film layer resin defocus lens): By setting a defocus area on the outer surface of the lens, and arranging microlens units in a spiral divergent pattern in the defocus area, combined with a separately set outer ring composite film layer, the defocus elimination effect of the lens is improved, the visual area can be widened more effectively, and eye fatigue will not be caused due to repeated switching when switching between near and far, which can provide good protection for the eyes and avoid the trouble of narrow visual area and eye fatigue during visual area conversion. This technical solution solves the above problems;

[0005] However, there are still some technical problems in the technical solution of this utility model. When the composite film layer resin defocus lens is used outdoors on a sunny day, strong sunlight shines on the lens, which will cause discomfort to the user's eyes. At the same time, when dirt appears on the outside of the composite film layer resin defocus lens, the user needs to use tools to clean it, which is rather inconvenient.

[0006] Therefore, a composite film layer resin defocus lens is proposed. Content of the Utility Model

By installing the connecting dirt scraping blade 8, when the user pulls down the ultraviolet ray shielding film 7, the connecting dirt scraping blade 8 can scrape the dirt outside the device, keeping the outside of the device clean, without the need to use external tools, enhancing the diversity of the device functions, and making the device cleaning more convenient. The connecting dirt scraping blade 8 is fixedly connected to the ultraviolet ray shielding film 7. By installing the magnetic adsorption strip 6, it can be adsorbed to the bottom metal adsorption strip 5, ensuring that the ultraviolet ray shielding film 7 is stably shielded outside the composite film layer resin defocusing lens body 1, enhancing the practicality of the device. The magnetic adsorption strip 6 is installed at the lower end of the connecting dirt scraping blade 8, and the magnetic adsorption strip 6 is fixedly connected to the connecting dirt scraping blade 8. The bottom metal adsorption strip 5 is installed at the lower end of the front end face of the composite film layer resin defocusing lens body 1.

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 , Figure 4 and Figure 5 ,A blue light blocking coating 2 is arranged on the front end face of the composite film layer resin defocusing lens body 1. By setting the blue light blocking coating 2, the device can have the function of blocking blue light, enhancing the use effect of the device, and effectively protecting the user's eye health. The blue light blocking coating 2 is fixedly connected to the composite film layer resin defocusing lens body 1. An external scratch resistant coating 3 is arranged on the front end face of the blue light blocking coating 2, and the external scratch resistant coating 3 is fixedly connected to the blue light blocking coating 2. The ultraviolet ray shielding film 7 includes a first transparent protective film 10, a second transparent protective film 11 and an anti-ultraviolet layer 12.

[0030] Working principle: When in use, the user only needs to pull down the magnetic adsorption strip 6 outdoors on a sunny day, so that the magnetic adsorption strip 6 pulls out the ultraviolet shielding film 7 wound around the outside of the flexible metal strip 9 from the upper bracket 4. Since both the flexible metal strip 9 and the ultraviolet shielding film 7 have a certain toughness, the flexible metal strip 9 can rotate, so that the ultraviolet shielding film 7 is released. When the user pulls down the magnetic adsorption strip 6, the connecting dirt scraping blade 8 at the upper end of the magnetic adsorption strip 6 wipes the outside of the device, keeping the outside of the device clean. Finally, the user only needs to make the magnetic adsorption strip 6 be in magnetic contact with the bottom metal adsorption strip 5. When the user needs to retract the ultraviolet shielding film 7, only by rotating the flexible metal strip 9 can the retraction of the ultraviolet shielding film 7 be realized. The flexible metal strip 9 is provided in this device to wind up the ultraviolet shielding film 7 by using the flexibility of the flexible metal strip 9, enhancing the flexibility of the device and making the device more convenient to use without worrying about the loss of accessories. Installing the ultraviolet shielding film 7 can block ultraviolet rays, prevent strong sunlight from affecting the user's eyes, avoid causing discomfort to the user, and make the device more user-friendly. Installing the connecting dirt scraping blade 8 can, when the user pulls down the ultraviolet shielding film 7, scrape the dirt on the outside of the device, keeping the outside of the device clean without using external tools, enhancing the diversity of the device functions and making the device cleaning more convenient. Installing the magnetic adsorption strip 6 can adsorb with the bottom metal adsorption strip 5 to ensure that the ultraviolet shielding film 7 stably blocks outside the composite film layer resin defocusing lens body 1, enhancing the practicality of the device. Setting the blue light blocking coating 2 can make the device have the function of blocking blue light, enhancing the use effect of the device and effectively protecting the user's eye health.
