Abstract
Description
[Technical Field]
[0001] This work relates to the technical field of optical lenses, specifically a morning light diffuser lens that reduces the large amount of high-energy blue light that is emitted during morning light. [Background Technology]
[0002] In the morning, sunlight moves closer to the sunlit area due to the sun's shift in position, resulting in a large amount of hot and irritating blue light being generated when it shines at an angle. Simultaneously, the rising temperature, rising water vapor, and interference from ambient air and suspended particles cause the morning light to undergo multi-directional refraction and polarization. Drivers or screen viewers in this morning sunlight environment, especially those wearing glasses with fully polarized lenses, are more susceptible to the effects of the aforementioned blue light, multi-directional refraction, and polarized light due to the 100% polarization of the lenses. This can lead to decreased image contrast, color discrimination errors, image aberrations, rainbow effects, and even blurred images.
[0003] Therefore, how to design a morning light soft lens that can improve the aforementioned problems is an urgent issue that needs to be addressed. [Utility Model Content]
[0004] This creation provides a morning light diffuser lens that reduces visual light pollution from the intense blue light produced by morning sunlight.
[0005] This innovative dawn light-diffusing lens comprises a polarizing lens and an optical coating. The polarizing lens provides 40% to 60% polarization. The optical coating is formed on the incident surface of the polarizing lens and includes a substrate structure and an adjustment structure. The substrate structure is stacked on the incident surface, and the adjustment structure is stacked on top of the substrate structure. The substrate structure comprises multiple layers of silica stacked sequentially, and the adjustment structure comprises multiple layers of titanium pentoxide and multiple layers of silica stacked alternately. Accordingly, this innovative dawn light-diffusing lens, utilizing a low-polarization lens combined with a coating design, can block a large amount of blue light during dawn without affecting color perception or visual clarity. It also reduces the likelihood of blackouts or rainbow effects caused by aberrations for drivers and screen viewers.
[0006] In one embodiment of this invention, the polarizing lens undergoes color addition and tone adjustment processing, and in conjunction with the setting of an optical coating, so that the light transmittance of the Dawn Soft Light Lens is maintained at an average of less than 17.63% for incident light in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm), an average of more than 5.36% for incident light in the wavelength range between 400 nanometers (nm) and 500 nanometers (nm), and an average of more than 7.25% for incident light in the wavelength range between 400 nanometers (nm) and 600 nanometers (nm).
[0007] In one embodiment of this invention, the polarizing lens is treated with color addition and color adjustment, and in conjunction with the setting of optical coating, the light transmittance of the morning light soft lens is reduced to an average of 10% to 12%.
[0008] In one embodiment of this invention, after color addition and color adjustment processing, the polarizing lens has a light transmittance of 13.38% to 54.11% in the incident light wavelength range between 600 nanometers (nm) and 700 nanometers (nm), and a light transmittance of 0.04% to 13.38% in the incident light wavelength range between 400 nanometers (nm) and 600 nanometers (nm).
[0009] In one embodiment of this invention, the Dawn Soft Light Lens has a light transmittance of 9.83% to 31.86% in the incident light wavelength range between 600 nanometers (nm) and 700 nanometers (nm), and a light transmittance of 0.02% to 9.83% in the incident light wavelength range between 400 nanometers (nm) and 600 nanometers (nm).
[0010] In one embodiment of this invention, the total number of stacked silicon dioxide layers in the substrate structure is 5.
[0011] In one embodiment of this invention, the total number of stacked layers of the multiple titanium pentoxide layers and multiple silicon dioxide layers with the adjusted structure is 12.
[0012] In one embodiment of this invention, the polarizing lens can provide 50% polarization effect.
[0013] Accordingly, the Morning Light Soft Lens of this creation utilizes polarized lenses with polarization effects in conjunction with a designed optical coating to filter the incident light of the morning light into unidirectional polarized light and adjust the light transmission spectrum of the lens to provide the effect of blocking blue light without affecting color discrimination and visual clarity, and in accordance with international standards.

The features and advantages of these embodiments will become more apparent from the following detailed description and claims.

For example, a component or structure containing multiple elements is not limited to those listed herein, but may include other elements not expressly listed but which are generally inherent to the component or structure.
[0033] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a structural diagram of the Dawn Soft Light Lens used in this creation. Figure 2 This is a partial structural diagram of the Dawn Soft Light Lens used in this creation. Figure 1 As shown, the morning light soft-focus lens 1 of this invention includes a polarizing lens 10 and an optical coating 20. The polarizing lens 10 is a low-polarization lens with a polarizing effect, used to filter incident light passing through the incident surface into single-directional polarized light. In this invention, the polarizing lens 10 is designed to provide a polarization effect (polarity) of 40% to 60%, which can effectively reduce screen blackouts or rainbow effects caused by aberrations when viewing a screen compared to a fully polarized lens. In a preferred embodiment of this invention, the polarizing lens 10 provides a polarization effect of 50%.
[0034] In this invention, the polarizing lens 10 undergoes color addition and tone adjustment processing to adjust the light transmission spectrum of the polarizing lens 10 to adapt to the morning light environment. The design for adjusting the light transmission spectrum of the polarizing lens 10 will be described in the following embodiments.
[0035] like Figure 1 and Figure 2 As shown, the optical coating 20 is formed on the incident surface 11 of the polarizing lens 10. The optical coating 20 reduces the excessive brightness of the image caused by the large amount of high color temperature blue light in the morning light, and, in conjunction with the polarizing lens 10, provides a further adjustment effect on the light transmission spectrum. The optical coating 20 includes a substrate structure 21 and an adjustment structure 22. The substrate structure 21 is formed on the incident surface 11 of the polarizing lens 10. The substrate structure 21 includes multiple silicon dioxide (SiO2) layers 211, which are stacked one layer at a time to ensure that the substrate structure 21 is not easily damaged by high temperatures during the subsequent formation of the adjustment structure 22. In one embodiment of this invention, the total number of stacked silicon dioxide layers 211 of the substrate structure 21 is 5 layers, but this invention is not limited to this.
[0036] The adjustment structure 22 is formed on the opposite side of the substrate structure 21 to the incident surface 11 of the polarizing lens 10; that is, the substrate structure 21 is located between the incident surface 11 of the polarizing lens 10 and the adjustment structure 22. The adjustment structure 22 includes multiple titanium pentoxide (Ti3O5) layers 221 and multiple silicon dioxide layers 222, which are stacked alternately layer by layer to form the adjustment structure 22; that is, in this invention, no titanium pentoxide layer 221 of the adjustment structure 22 will contact another titanium pentoxide layer 221, and no silicon dioxide layer 222 of the adjustment structure 22 will contact another silicon dioxide layer 222. In one embodiment of this invention, the total number of stacked layers of the plurality of titanium pentoxide layers 221 and the plurality of silicon dioxide layers 222 of the adjustment structure 22 is 12 layers, that is, the adjustment structure 22 includes 6 layers of titanium pentoxide layers 221 and 6 layers of silicon dioxide layers 222, but this invention is not limited thereto.
[0037] The polarized lens 10 of this invention undergoes color addition and toning treatment, and in conjunction with the optical coating 20, the final Dawn Soft Light Lens 1 maintains an average light transmittance of less than 17.63% for incident light in the wavelength range between 600 nm and 700 nm (i.e., the red light band), an average light transmittance of more than 5.36% for incident light in the wavelength range between 400 nm and 500 nm, and an average light transmittance of more than 7.25% for incident light in the wavelength range between 400 nm and 600 nm. Therefore, by utilizing the polarized lens 10 and the optical coating 20 to achieve the effect of adjusting the light transmittance spectrum, the Dawn Soft Light Lens 1 provides users with a considerable degree of visual clarity when wearing it, and meets the international standards for sunglasses lenses from various countries, including the US FDA, Australia and New Zealand, and the European Union.
[0038] Please refer to Figure 3 This is a schematic diagram of the light transmission spectrum corresponding to the polarized lens of the Morning Light Soft Lens created for this project, after color addition and tonal adjustment. (See diagram below.) Figure 1 and Figure 3 As shown, in one embodiment of this invention, after color addition and color tone adjustment processing, the polarizing lens 10 of the morning light soft lens 1 of this invention is adjusted to have a light transmittance of 13.38% to 54.11% for incident light in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm), and the average light transmittance in the aforementioned wavelength range is 28.61%; furthermore, the light transmittance of the polarizing lens 10 for incident light in the wavelength range between 400 nanometers (nm) and 600 nanometers (nm) is adjusted to have a light transmittance of 0.04% to 13.38% for incident light in the wavelength range between 400 nanometers (nm) and 600 nanometers (nm), and the average light transmittance in the aforementioned wavelength range is 14.11%. Figure 3 Detailed data on light transmittance of the light transmission spectrum shown in the figure can be found in Table 1 below.

[0041]
[0042] Please refer to Figure 4 This diagram illustrates the light transmission spectrum of the Dawn Soft Light Lens, created using polarized lenses and optical coatings. (See diagram for reference.) Figure 1 and Figure 4 As shown, in one embodiment of this invention, the polarizing lens 10 of the present invention's Dawn Soft Light Lens 1 undergoes the aforementioned color addition and tone adjustment processing, and in conjunction with the optical coating 20, the overall Dawn Soft Light Lens 1's light transmittance in the incident light band between 600 nanometers (nm) and 700 nanometers (nm) is adjusted to 9.83% to 31.86%, with an average light transmittance of 17.63% in the aforementioned band. Furthermore, the overall Dawn Soft Light Lens 1's light transmittance in the incident light band between 400 nanometers (nm) and 600 nanometers (nm) is adjusted to 0.02% to 9.83%, with an average light transmittance of 7.25% in the aforementioned band. In this embodiment, the present invention's Dawn Soft Light Lens 1 reduces light transmittance to an average of 10% to 12%, more preferably to an average of 10.85%, while increasing spectral contrast through the optical coating 20 without affecting clarity. Figure 4 Detailed data on light transmittance of the light transmission spectrum shown in the figure can be found in Table 2 below.

[0045]
[0046] Accordingly, the present invention's Morning Light Soft Lens 1 utilizes a polarized lens 10 that has undergone color addition and toning treatment, in conjunction with an optical coating 20, to adjust the light transmission spectrum corresponding to the overall Morning Light Soft Lens 1. This allows the present invention's Morning Light Soft Lens 1 to block a large amount of blue light when the morning light shines obliquely in the morning light environment, without affecting color discrimination and maintaining visual clarity.
[0047] Furthermore, in this invention, the optical coating 20 is formed on the incident surface 11 of the polarizing lens 10 by electroplating using an electroplating target of a corresponding material. In one embodiment of this invention, the polarizing lens 10 and the electroplating target of the corresponding material can be placed in an environment with environmental conditions of 5 × 10⁻⁶. -4In a vacuum electroplating environment of Pa, an ion-assisted deposition method is used to perform an electroplating process on the incident surface 11 of the polarizing lens 10 to form an optical coating 20. The optical coating 20 formed by the aforementioned method can increase the adhesion and hardness of multilayer electroplating. Specifically, silicon dioxide (SiO2) is first used as the electroplating target to form the substrate structure 21 of the optical coating 20, and then titanium pentoxide (Ti3O5) and silicon dioxide (SiO2) are used as electroplating targets alternately to form the adjustment structure 22 of the optical coating 20, and finally the overall optical coating 20 is formed.
[0048] In one embodiment of this invention, an ultra-low temperature cryogenic pump can be configured in the aforementioned vacuum electroplating environment. Since the total number of stacked layers of the optical coating 20 during the electroplating process is as high as 17, the high ambient temperature can cause the material to release water molecules or material waste gas, affecting the coating effect and material adhesion. Therefore, the ultra-low temperature cryogenic pump provides a condensation and adsorption effect on the water molecules or material waste gas in the vacuum electroplating environment, making the water molecules or material waste gas inert and maintaining the coating adhesion under vacuum conditions, thereby achieving the aforementioned adjustment requirement for the light transmission spectrum.
