Description
Technical Field
The utility model belongs to the resin lens field, more specifically relates to a prevent anti infrared coating film resin lens of blue light.
Background
In recent years, the popularization of functional resin lenses is accepted and welcomed by the market, particularly for the protection of ultraviolet and blue light bands, because the light rays in the bands can easily penetrate through the crystalline lens of the eyes to reach the retina, the oxidation process of the macular area of the eyes is rapidly accelerated to cause great damage to the eyes, the symptoms of dry eyes, unsmooth eyes, aching eyes and the like can be caused, and the fundus damage after cataract operation can also be caused. The blue light can inhibit the secretion of melatonin, disturb sleep and improve the incidence rate of serious diseases per se. At present, the resin lenses for protecting ultraviolet and blue light bands on the market are of various varieties, including low refractive index 1.50 and even high refractive index 1.74, and the effective protection wavelength is different. In addition, the research on the protection of the eyes from infrared rays is very rare, and actually, when the wavelength of the infrared rays reaches a certain range, the damage to the eyes is relatively large.
The infrared ray is an electromagnetic wave having a wavelength between microwave and visible light, and has a wavelength value in the range of 700nm to 4 μm. According to the wavelength value, the infrared light can be classified into near infrared light and middle and far infrared light. The wavelength of the near infrared is 700-1400 nm, and the wavelength of the mid-infrared and far-infrared is 1400-4 μm. In environments with intense light and heat radiation, there is a significant amount of infrared radiation present. In daily life, people have less chance to be exposed to environments with strong light and heat radiation, but this does not mean that ordinary people do not need daily protection of their eyes. It is known that 10% of solar radiation is ultraviolet energy, about 40% is visible light, and the remaining about 50% is all infrared light. Infrared light has a strong penetrating power, and a large amount of infrared light can be irradiated or reflected to the human eye. Near infrared light can reach the fundus and is mainly absorbed by the retina; the mid-far infrared light and the far infrared light are mainly absorbed by the cornea and cannot reach the fundus. When the eye mask works in an environment with strong light or heat radiation for a long time, eyes feel dry and fatigue, and even eye diseases such as glaucoma and the like are caused; the common optical spectacle lens has no filtering function on infrared rays, so that effective visible light can be filtered out while infrared rays are filtered out by colored sunglasses, and the defects of unclear object viewing and poor color distinguishing performance when the colored sunglasses are worn are overcome.
The optical resin lenses in the market only generally can only protect blue light or near infrared light, but cannot protect both harmful lights at the same time. However, it is difficult to solve the problem of the blue light and infrared light prevention without affecting the transmittance of visible light. In a general coating process, a coating material with a high refractive index is usually titanium oxide, but titanium has a high melting point, needs to be heated to an ultrahigh temperature in a burning process of the coating process, has serious damage to equipment, needs to be melted in advance, is troublesome to operate, and has an unstable valence state in an evaporation process, so that the effect of a prepared lens is unstable.
