Description

Technical Field

[0001] The utility model belongs to the technical field of resin lenses, and in particular relates to a hardened blue light-proof resin garage lens. Background Art

[0002] As resin lenses are becoming more and more popular among consumers due to their advantages such as light weight, vibration resistance, easy dyeing, easy molding, good elasticity, high refractive index, and UV resistance, it is becoming increasingly necessary to process the surface due to their inherent shortcomings such as low surface hardness, easy scratches, and poor thermal properties.

[0003] Blue light is an important component of visible light. There is no separate white light in nature. Blue light is mixed with green light and yellow light to present white light. Green light and yellow light have lower energy and less stimulation to the eyes. Blue light has short wavelength and high energy and can directly penetrate the lens and reach the retina at the fundus. Studies have shown that if photoreceptor cells are exposed to blue-violet light for a long time, the pigment molecules in the cells will trigger a phototoxic reaction, causing lesions in the macula. The stronger the light, the greater the damage. Therefore, macular degeneration is no longer exclusive to the elderly. In today's society, with the change of living habits, long-term exposure to blue-violet light stimulation (such as computers, televisions, outdoor sunlight, etc.), especially in today's era of popularization of televisions, computers, and touch-screen mobile phones, eye health has become a major issue. For normal people like us, blocking long-term exposure to blue light is the most effective way to reduce damage, and using anti-blue light lenses can effectively solve this problem. Ordinary anti-ultraviolet lenses can only filter ultraviolet rays, but not blue light.

[0004] In addition, through actual mass production, it is found that a considerable number of coated lenses will have premature aging and damage to their anti-blue light film after long-term use. In addition, fine cracks will appear at the joints between the hardened film layer and other film layers, which is often referred to as dark cracks by industry insiders. This defect is more obvious after a 24-hour salt water soaking test. This will cause the anti-blue light film layer and the hardened layer to have poor adhesion, affecting the hardness of the lens itself and the anti-blue light effect. Therefore, a new type of hardened anti-blue light lens with a new structure is urgently needed. Utility Model Content

[0005] In view of this, the technical problem to be solved by the utility model is to provide a hardened anti-blue light resin garage lens, which is used to avoid the trouble that the hardness and anti-blue light effect of the previous resin lens deteriorate in adhesion and durability after a long time.

[0006] In order to solve the above technical problems, the utility model discloses a hardened blue light protection resin garage lens, which comprises:

[0007] Resin substrate;

[0008] A composite hard coating layer group is dip-coated on the surface of the resin substrate, the composite hard coating layer group includes an organic silicon bottom layer, a silicon-zirconium mixed layer, and an organic silicon outer layer;

[0009] The anti-blue light film layer is plated on the surface of the composite hard film layer group, and the anti-blue light film layer includes a silicon dioxide layer, a titanium dioxide layer, a silicon dioxide layer, a titanium dioxide layer, a silicon dioxide layer, and an indium tin oxide layer from the inside to the outside;

[0010] A UV-curable protective layer spin-coated on the surface of the blue light protection film layer;

[0011] A silicon fluoride layer is disposed on the surface of the ultraviolet light curing protective layer.

[0012] According to one embodiment of the utility model, the thickness of the organic silicon bottom layer and the organic silicon outer layer are both greater than the thickness of the silicon-zirconium mixed layer.

[0013] According to an embodiment of the present invention, the thickness of the hardened film layer group is 2.7±0.5 um.

[0014] According to one embodiment of the utility model, the thickness of the above-mentioned anti-blue light film layers from inside to outside are: silicon dioxide layer 30-60nm; titanium dioxide layer 30-45nm; silicon dioxide layer 27-40nm; titanium dioxide layer 27-40nm; silicon dioxide layer 80-120nm; and indium tin oxide layer 4-7nm.

[0015] According to one embodiment of the present invention, the silicon fluoride layer is deposited by electron gun evaporation and has a thickness of 15 to 20 nm.

[0016] Compared with the prior art, the utility model can obtain the following technical effects:

[0017] By setting a composite hardened film layer group consisting of a silicone bottom layer, a silicon-zirconium mixed layer, and a silicone outer layer, the hardness of the resin substrate itself is improved. At the same time, an anti-blue light film layer is plated on the outside. The anti-blue light effect is enhanced by the combination of 6 layers of films. The ultraviolet light-cured protective layer cures the protective film layer to prevent it from wear and oxidation. The fluorine in the outermost silicon fluoride layer reacts with silicon to form a bond, and the surface has a high hydrophobicity.

[0018] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figure 1 , Figure 1 It is a schematic diagram of a hardened blue light-proof resin garage lens according to an embodiment of the utility model.

[0026] In one embodiment of the utility model, the resin substrate 10 is formed by curing a resin monomer, and the surface is dip-coated with a composite hard film layer group, which is used to improve the hardness of the resin substrate 10, and is specifically composed of an organic silicon bottom layer 20, a silicon-zirconium mixed layer 30, and an organic silicon outer layer 40. The organic silicon bottom layer 20 and the organic silicon outer layer 50 form a uniform protective layer on the surface of the resin substrate 10 through a sol-gel process, and the middle silicon-zirconium mixed layer 30 improves the refractive index in the middle and improves the anti-reflection effect. Furthermore, the thickness of the organic silicon bottom layer 20 and the organic silicon outer layer 40 are greater than the thickness of the silicon-zirconium mixed layer 30, which improves the internal and external protection strength.

[0027] Preferably, the thickness of the hard coating layer group is 2.7±0.5 um.

[0028] The anti-blue light film layers are sequentially arranged from the inside to the outside as a silicon dioxide layer 51, a titanium dioxide layer 52, a silicon dioxide layer 53, a titanium dioxide layer 54, a silicon dioxide layer 55, and an indium tin oxide layer 56, wherein the silicon dioxide layer 51 is a low refractive index film layer, and the titanium dioxide layer 52 is a high refractive index film layer, which are continuously superimposed to filter out blue light, and the indium tin oxide layer 56 is a thinner coating layer with anti-static function.

[0029] Preferably, the thickness of the anti-blue light film layers from inside to outside are: 30-60nm silicon dioxide layer; 30-45nm titanium dioxide layer; 27-40nm silicon dioxide layer; 27-40nm titanium dioxide layer; 80-120nm silicon dioxide layer; and 4-7nm indium tin oxide layer, which are continuously superimposed to reduce reflection and increase transmittance, thereby improving the anti-blue light effect.

[0030] In addition, a UV-curable protective layer 60 is spin-coated on the outer side of the anti-blue light film layer. The protective layer formed by UV curing is used to prevent the anti-blue light film layer from being worn and oxidized. The silicon fluoride layer 70 is evaporated by an electron gun and has a thickness of 15 to 20 nm. It is a waterproof protective layer on the outer side of the lens.

[0031] In summary, the utility model improves the hardness of the resin substrate itself by providing a composite hardened film layer group consisting of a silicone bottom layer 20, a silicon-zirconium mixed layer 30, and a silicone outer layer 40, and at the same time, an anti-blue light film layer is plated on the outside. The anti-blue light effect is enhanced by the combination of 6 layers of films, and the ultraviolet light curing protective layer 60 cures the protective film layer to prevent it from wear and oxidation. The fluorine in the outermost silicon fluoride layer 70 reacts with silicon to form a bonded surface with high hydrophobicity.
