Description

Technical Field

[0001] The utility model belongs to the technical field of resin lenses, and specifically relates to a multifunctional anti-reflection lens. Background Art

[0002] When light passes through the lens, it will be reflected on the front and back surfaces of the lens, and the transmittance of the lens will be affected. Low transmittance will affect the visual effect of the wearer, and low clarity and primary color saturation will cause more eye fatigue. The so-called anti-reflection film, also known as anti-reflection film, has the main function of reducing or eliminating the reflected light on the optical surface of the lens, thereby increasing the light transmittance of the lens and reducing or eliminating interfering stray light. In the eyewear industry, anti-reflection film is currently the most widely used and largest-volume optical film for eyeglass lenses. Currently, most anti-reflection films are designed with ordinary metal oxide single films, which have weak anti-reflection and anti-reflection effects, and are easily affected by the transmittance of the lens after plating, and are less practical. Utility Model Content

[0003] In view of this, the technical problem to be solved by the utility model is to provide a multifunctional anti-reflection lens, which is used to avoid the problems of weak anti-reflection and anti-transmission effects and low light transmittance of conventional resin lenses.

[0004] In order to solve the above technical problems, the utility model discloses a multifunctional anti-reflection lens, which comprises:

[0005] A substrate layer, wherein the front and rear surfaces of the substrate layer respectively have a plurality of protruding nanometer micro-light units, and the nanometer micro-light units on the front and rear surfaces are staggered with each other;

[0006] A silicon-zirconium mixed film layer formed on the surface of the substrate layer by sol-gel;

[0007] A first anti-reflection film group plated on the surface of the silicon-zirconium mixed film layer, the first anti-reflection film group comprising a first zirconium oxide film layer, a second silicon dioxide film layer, a third zirconium oxide film layer, a fourth silicon dioxide film layer, a fifth zirconium oxide film layer, a sixth silicon dioxide film layer, and a seventh titanium dioxide film layer;

[0008] A high refractive index film layer coated on the surface of the first anti-reflection film layer;

[0009] a second anti-reflection film group coated on the surface of the high refractive index film layer, the second anti-reflection film group comprising a first silicon dioxide film layer, a second aluminum oxide film layer, a third silicon dioxide film layer, a fourth aluminum oxide film layer, a fifth silicon dioxide film layer, a sixth aluminum oxide film layer, and an indium tin oxide film layer; and

[0010] A waterproof film layer is plated on the surface of the second anti-reflection film group.

[0011] According to an embodiment of the utility model, the nanometer micro-light unit is configured as a circular protrusion, and increases the positive refractive power relative to the substrate layer.

[0012] According to an embodiment of the present invention, the thickness of the first anti-reflection film group is 150-350 nm.

[0013] According to an embodiment of the present invention, the thickness of the second anti-reflection film group is 90-170 nm.

[0014] According to one embodiment of the present invention, the waterproof membrane layer is configured as a fluorine-containing polymer layer.

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

[0016] By setting nano-microlight units on the surface of the substrate layer, reflection is enhanced. At the same time, a high-refractive index film layer is sandwiched between the first anti-reflection film group and the second anti-reflection film group to increase the refractive index of the lens while reducing reflection and increasing transmittance, thereby ensuring the light transmission effect. The outer waterproof film layer improves the waterproofness of the lens.
