Description

Technical Field

[0001] The invention belongs to the technical field of lenses, and in particular relates to a process for a high-protection anti-reflection film heat-insulating resin lens. Background Art

[0002] Optical resin lenses are optical lenses made of polymer resin materials. Compared with glass lenses, they have the advantages of light weight, strong impact resistance, low cost and meeting special needs, and have been widely used. In recent years, the promotion of functional resin lenses has been recognized and welcomed by the market, especially for the protection of ultraviolet and blue light bands, because the light in these bands can easily penetrate the lens of the eye and reach the retina, rapidly accelerating the oxidation process in the macular area of ​​the eye and causing great damage to the eyes, leading to symptoms such as dry eyes, astringent eyes and sore eyes, and can also cause fundus damage after cataract surgery. Blue light can inhibit the secretion of melatonin, disturb sleep, and increase the incidence of major diseases. At present, there are many varieties of resin lenses on the market for protecting ultraviolet and blue light bands, including low refractive index 1.50 and even high refractive index 1.74, and the effective protection wavelength is also different. However, there is very little research on infrared protection glasses. In fact, when the wavelength of infrared reaches a certain range, the damage to the eyes is relatively large.

[0003] Infrared is an electromagnetic wave with a wavelength between microwaves and visible light, ranging from 700nm to 4μm. According to the size of the wavelength, it can be divided into near infrared and mid- and far infrared. The wavelength of near infrared is 700-1400nm, while mid- and far infrared is 1400nm-4μm. In an environment with strong light and thermal radiation, there is a large amount of infrared radiation. In daily life, people have fewer opportunities to come into contact with an environment with strong light and thermal radiation, but this does not mean that ordinary people's eyes do not need daily protection. It is known that 10% of solar radiation is ultraviolet light energy, about 40% is visible light, and the remaining 50% is all infrared light. Infrared light has a strong penetrating power, and a large amount of infrared light can be irradiated or reflected into the human eye. Near infrared light can reach the fundus and is mainly absorbed by the retina; mid- and far infrared light and far infrared light are mainly absorbed by the cornea and cannot reach the fundus. Working in an environment with strong light or heat radiation for a long time will make the human eyes feel dry and tired, and may even cause eye diseases such as glaucoma and cataracts. Ordinary optical lenses do not filter infrared light. Even tinted sunglasses will filter out effective visible light while filtering out infrared rays. Therefore, wearing tinted sunglasses has the disadvantages of unclear vision and poor color discrimination.

[0004] With the development of science and technology and the improvement of people's living standards, optical lenses are increasingly used in daily life and work. However, traditional optical lenses often only focus on optical performance and ignore other functions such as heat insulation and near-infrared protection. Therefore, developing a lens with excellent optical performance and heat insulation, near-infrared protection and other functions will have high practical value. Summary of the invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide a high-protection anti-reflection film heat-insulating resin lens process to avoid the trouble of poor anti-reflection and heat-insulating properties of previous lenses.

[0006] In order to solve the above technical problems, the present invention discloses a high protection anti-reflection film heat-insulating resin lens process, which comprises: Step a. providing a cured resin substrate, treated with a sodium hydroxide solvent, and then ultrasonically cleaned; Step b.

A nano-insulation film layer is deposited on the surface of the antireflection film layer by vacuum sputtering, and oxygen is introduced at a flow rate of 180-300 SCCM; Step h. Take out and dry to complete packaging.

[0007] According to one embodiment of the present invention, the nano thermal insulation film layer is sputtered onto the surface of the resin substrate using magnesium fluoride, silicon dioxide, organic silicon, or titanium silicon nitride as target materials.
