Description

Technical Field

[0001] The utility model belongs to the technical field of resin lenses, and specifically relates to a high-definition polarized anti-blue light lens. Background Art

[0002] Blue light is an important component of visible light. White light in nature is a mixture of blue light, green light and yellow light. Among them, green light and yellow light have lower energy and less stimulation to the eyes, while blue light has short wavelength and high energy, and can directly penetrate the lens and reach the retina at the fundus. Therefore, blue light can easily cause eye fatigue, and anti-blue light glasses can play a certain protective role for the eyes, especially for people who stare at electronic screens for a long time. At present, the anti-blue light glasses market is mixed, with a wide variety of types, including amethyst film, gold film, blue film, green film, yellow-green film, etc. However, these anti-blue light glasses are prone to chromatic aberration and poor anti-blue light performance. In addition, glare will occur when worn at night or in the snow, and the polarization function needs to be further strengthened. Utility Model Content

[0003] In view of this, the technical problem to be solved by the present invention is to provide a high-definition polarized anti-blue light lens, which is used to avoid the problem that the previous resin lenses have weak polarization and anti-blue light effects.

The 1.64 refractive index film layer includes a first aluminum oxide film layer, a second silicon dioxide film layer, a third aluminum oxide film layer, a fourth silicon dioxide film layer, a fifth aluminum oxide film layer, and a sixth silicon dioxide film layer.

[0011] According to one embodiment of the present invention, the polarizing film is configured as a PVA film.

[0012] According to one embodiment of the utility model, the hardened layer is provided with an organic silicon film layer, and the thickness is 50-200 μm.

[0013] According to an embodiment of the present invention, the thickness of the film layer with a refractive index of 1.84 is 150-280 μm; the thickness of the film layer with a refractive index of 1.64 is 200-320 μm.

[0014] According to an embodiment of the present invention, a silicon fluoride film layer is further coated on the front side of the 1.84 refractive index film layer.

[0015] Compared with the prior art, the utility model can obtain the following technical effects:

[0016] A triacetyl cellulose film layer is applied to the polarizing film to enhance the light transmittance and hardness of the polarizing film, and then the resin substrate layer is cured on both sides. Combined with the 1.84 refractive index film layer and 1.64 refractive index film layer plated on the front and back respectively, the anti-reflection and anti-blue light effects are enhanced.

[0022] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Please refer to Figure 1 , Figure 1 It is a schematic diagram of a high-definition polarized anti-blue light lens according to an embodiment of the utility model.

[0024] As shown in the figure, a high-definition polarized anti-blue light lens comprises: a polarizing film 10, the thickness of the polarizing film 10 is 3.0 μm-4.0 μm; a triacetyl cellulose film layer 20 arranged on the surface of the polarizing film 10; a resin substrate layer 30 respectively solidified and formed on the front and rear surfaces of the triacetyl cellulose film layer 20; a hardening layer 40 dip-coated on the surface of the resin substrate layer 30; a 1.84 refractive index film layer 50 plated on the surface of the hardening layer 40 and located on the front side of the resin substrate layer 30; a 1.84 refractive index film layer 51; a 1.84 refractive index film layer 52; a 1.84 refractive index film layer 53; a 1.84 refractive index film layer 54; a 1.84 refractive index film layer 55; a 1.84 refractive index film layer 56; a 1.84 refractive index film layer 57; a 1.84 refractive index film layer 58; a 1.84 refractive index film layer 59; a 1.84 refractive index film layer 59; a 1.84 refractive index film layer 50; a 1.84 refractive index film layer 51; a 1.84 refractive index film layer 52; a 1.84 refractive index film layer 53; a 1.84 refractive index film layer 54; a 1.84 refractive index film layer 56; a 1.84 refractive index film layer 57; a 1.84 refractive index film layer 58; a 1.84 refractive index film layer 59; a 1.84 refractive index film layer 59; a 1.84 refractive index film layer 59 50 includes a first titanium dioxide film layer, a second zirconium dioxide film layer, a third titanium dioxide film layer, a fourth zirconium dioxide film layer, a fifth titanium dioxide film layer, and a sixth zirconium dioxide film layer; a 1.64 refractive index film layer 60 plated on the surface of the hardened layer 40 and located on the rear side of the resin substrate layer 30, and the 1.64 refractive index film layer 60 includes a first aluminum oxide film layer, a second silicon dioxide film layer, a third aluminum oxide film layer, a fourth silicon dioxide film layer, a fifth aluminum oxide film layer, and a sixth silicon dioxide film layer.

[0025] In one embodiment of the utility model, the polarizing film 10 is set as a PVA film with a thickness of only 3.0μm-4.0μm, which is a soft film design, ensuring the polarizing effect while also having good light transmittance. At the same time, the triacetylcellulose film layer 20 can further enhance its polarizing light transmittance, and after coating, it can also enhance its hardness, avoid the polarizing film 10 from warping, and improve the adhesion of the resin substrate layer 30 after curing.

[0026] The hardening layer 40 is provided with an organic silicon film layer and has a thickness of 50-200 μm, so as to improve the surface hardness of the resin substrate layer 30 .

[0027] In addition, a 1.84 refractive index film layer 50 and a 1.64 refractive index film layer 60 are respectively plated on the front and rear surfaces of the resin substrate 30. The front surface has a higher refractive index, while the rear surface has a lower refractive index. The combination of the two can enhance the anti-reflection effect of the lens and avoid interference from stray strong light. Moreover, the 1.84 refractive index film layer 50 and the 1.64 refractive index film layer 60 are respectively made of titanium dioxide film layer, titanium dioxide film layer; aluminum oxide film layer, and silicon dioxide film layer, which continuously filter out refraction to achieve an anti-blue light effect.

[0028] Preferably, the thickness of the film layer 50 with a refractive index of 1.84 is 150-280 μm; the thickness of the film layer 60 with a refractive index of 1.64 is 200-320 μm, which has a good effect in reducing blue light.

[0029] In addition, the front side of the 1.84 refractive index film layer 50 is also coated with a silicon fluoride film layer to enhance the scratch resistance of the front surface.

[0030] In summary, the utility model coats the triacetyl cellulose film layer 20 on the polarizing film 10 to enhance the light transmittance and hardness of the polarizing film 10, and then solidifies the resin substrate layer 30 on both sides, and cooperates with the 1.84 refractive index film layer 50 and the 1.64 refractive index film layer 60 plated on the front and back respectively to enhance the anti-reflection and anti-blue light effects.
