[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 This is a cross-sectional schematic diagram of a lens according to one embodiment of the present invention; Figure 2 This is a schematic diagram of an anti-fingerprint film according to one embodiment of the present invention.

[0019] An anti-fingerprint blue light blocking resin lens includes: a substrate 1; the front and back surfaces of the substrate 1 are provided with an anti-blue light film layer 2, an anti-reflective film layer 3 and an anti-fingerprint film layer 4 from the inside out, the anti-blue light film layer 2 is an alternating composite film layer of titanium pentoxide film layer and silicon dioxide film layer, the anti-reflective film layer 3 is an alternating composite film layer of magnesium fluoride film layer and titanium pentoxide film layer, and the anti-fingerprint film layer 4 is a perfluoropolyether film layer; the lens 5 is covered with an anti-fingerprint film 6, and the edge of the anti-fingerprint film 6 is provided with a ring array of folded portions 7, which are folded upward.

[0020] The blue light blocking film layer 2 has three layers of titanium pentoxide film and three layers of silicon dioxide film. The alternating arrangement of the low-refractive-index silicon dioxide film and the high-refractive-index titanium pentoxide film can play a role in filtering light and blocking harmful blue light in a specific wavelength range.

[0021] The antireflective coating 3 has five layers of magnesium fluoride film and five layers of titanium pentoxide film. The magnesium fluoride film has a lower refractive index and a better antireflective effect. The alternating arrangement of the low-refractive-index magnesium fluoride film and the high-refractive-index titanium pentoxide film can play a role in reducing reflection and enhancing antireflection.

[0022] The thickness of the titanium pentoxide film is 10–50 nanometers, the thickness of the silicon dioxide film is 10–50 nanometers, the thickness of the magnesium fluoride film is 50–100 nanometers, and the thickness of the anti-fingerprint film is 2–10 nanometers.

[0023] The anti-fingerprint film layer 4 is a perfluoropolyether film layer, which has extremely low surface tension and can effectively prevent fingerprints and various stains from adhering, making the surface of the object less prone to grease and dust, and easy to wipe and clean.

[0024] The lens 5 is placed on the anti-fingerprint film 6, and the folded part 7 on its edge folds upward to cover the lens 4. The sides between adjacent folded parts 7 are pointed. This design of the folded parts 7 makes it easy for the lens 5 to be inserted into the anti-fingerprint film 6. The folded edge of the folded part 7 is arc-shaped, and the opposite edge of the folded edge is concave. The edge of the anti-fingerprint film 6 can fit the edge of the lens 5. Under the constraint of the arc edge, the folded part 7 can fit the surface of the lens 5. In this way, when the lens 5 is packaged and taken out, it can avoid the finger directly touching the surface and leaving marks.

[0025] This invention provides an anti-blue light film layer 2 and an anti-reflection film layer 3 on the surface of the substrate 1, which can block harmful blue light, reduce reflection and glare, and improve the clarity of vision. It also provides an anti-fingerprint film layer 4, which has good hydrophobic and oleophobic effects and can reduce fingerprint contamination of the lens. Furthermore, an anti-fingerprint film 6 is used to cover the lens 5, so that fingers do not come into contact with the lens 5 when taking it out.

[0026] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
