Description

Technical Field

[0001] This utility model relates to the field of resin lens technology, specifically to an anti-reflective lens that is resistant to temperature changes. Background Technology

[0002] Light passing through a lens is reflected at both the front and back surfaces, affecting the lens's transmittance. Low transmittance impacts the wearer's visual experience, leading to reduced clarity and color saturation, which in turn causes eye strain. Anti-reflective coatings, also known as light-reflecting coatings, primarily function to reduce or eliminate reflected light from the lens's optical surfaces, thereby increasing light transmission and reducing or eliminating stray light. Their main working principle utilizes interference to cancel out light passing through the coating, achieving the purpose of reducing reflection.

[0003] In the eyewear industry, antireflective coatings are currently the most widely used and produced type of optical film for eyeglass lenses. Most current antireflective coatings use a single-layer design with ordinary metal oxide. However, single-layer antireflective coatings have a very narrow antireflection wavelength range, resulting in weak antireflection and antireflection effects and poor practicality. Furthermore, ordinary lenses lack resistance to both low and high temperatures, and their optical performance, physical structure, and material properties are easily affected by temperature changes.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings. Specific implementation examples:

[0020] As attached Figure 1 As shown, an anti-reflective lens resistant to temperature changes includes a substrate layer 1, which is formed by curing transparent resin. The transparent resin includes acrylic resin, styrene resin, polycarbonate, polyolefin resin and diethylene glycol dielyl carbonate. The silicone hardening layer 2 is formed on the surface of the substrate layer 1 by sol-gel molding. The silicone hardening layer 2 is a highly cross-linked siloxane resin layer, which is used to improve the surface hardness. On the one hand, it can prevent the resin substrate layer from being scratched and affecting the vision correction effect, and on the other hand, it can facilitate the subsequent processing of the anti-reflection film layer 3. At least one antireflective film layer 3 is disposed on the upper surface of the organosilicon hardening layer 2, preferably 3-5 layers; the antireflective film layer 3 includes a zirconium oxide-silica mixed bottom film layer 31 and a silicon dioxide top film layer 32; preferably, the molar ratio of zirconium oxide and silicon dioxide in the zirconium oxide-silica mixed bottom film layer 31 is 3:2-4:1. The steps for forming the antireflective thin film layer are as follows: The zirconia-silica hybrid bottom film layer 31 is formed on the upper surface of the organosilicon hardening layer 2 by a sol-gel method; the silica top film layer 32 is formed on the upper surface of the zirconia-silica hybrid bottom film layer 31 by a sol-gel method.

[0021] In this embodiment, the refractive index of the zirconium oxide-silica mixed bottom film 31 is controlled by adjusting the molar ratio of zirconium oxide and silicon dioxide. It has a suitable gradient with the refractive index of the silicon dioxide top film 33, which can achieve a broadband anti-reflection effect.

[0022] It also includes a low-temperature resistant film layer 4 disposed on the upper surface of the antireflective film layer 3 and the lower surface of the substrate layer 1, and a high-temperature resistant film layer 5 disposed on the surface of the low-temperature resistant film layer 4; preferably, the low-temperature resistant film layer 4 is made of polyethylene material; the high-temperature resistant film layer 5 is made of ZS-322 transparent high-temperature resistant coating.

[0023] To further improve the waterproof performance, a waterproof membrane layer 6 is also set on the surface of the high-temperature resistant thin film layer 5.

[0024] Preferably, the waterproof membrane layer 6 is a fluoropolymer layer.

Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention.
