Lens coating

Lenses in order to obtain some new, originally do not have the excellent performance, in the surface of the spectacle lens with physical and chemical methods, coated with a certain thickness of single or multi-layer optical thin.

Reinforcement film: also called hardening film, is a layer of metal oxides with similar refractive index to the lens and coupling agent mixed into the film layer. It has the characteristics of high hardness, high adhesion, high light transmission, etc. It can effectively improve the wear resistance of lenses, not easy to peel off the film and yellowing, and greatly improve the service life of lenses.

Reflection-reducing film: also called transmittance-enhancing film, it utilizes the principle of light interference to make the light reflected back through the two sides of the film layer to interfere and thus cancel each other out, reducing or eliminating the reflection of light from the lens, thus enhancing the light transmission of the lens. Generally, it is difficult to achieve the desired effect with a single layer of reflective film, because one layer of reflective film only has the effect of reducing the reflection of a certain wavelength, and often double, triple or even more layers of reflective film are used to improve the effect of increasing the transmittance of the whole wavelength range of visible light, so as to make the lenses more translucent.

Durable top film: also called hydrophobic and oleophobic film, commonly known as waterproof film, using evaporation method, fluoride and other water-repellent materials evaporation deposition on the surface of the lens and become, through the water-repellent substances and tight film surface, reduce the contact area of water / oil and lens, so that the water / oil is not easy to adhere to the surface of the lens, to ensure that the visual effect of the lens, and at the same time, easier to clean.

Anti-static film: generally indium tin oxide (ITO) material is used in the lens surface plated into a thin film, with good conductivity and transparency, ITO film can effectively eliminate the accumulation of static electricity on the surface of the lens to reduce the dust adsorption on the surface of the lens.
