Description
Technical Field
The invention relates to the technical field of optical lenses, in particular to an infrared and ultraviolet resistant optical lens and a preparation method thereof.
Background
As the eyeglass market has expanded, its lenses have also gained increased consumer attention. Thus, with the diversification of consumer demand, various aspects of lens performance and technology are continually improving and perfecting. At present, on the basis of hardened lenses, the coated lenses in the market are mainly coated with an antireflection film layer, a top waterproof layer and the like by a vacuum coating method. So as to achieve the effects of enhancing the transmittance and protecting the lens. Various lenses in life are used as daily carrying articles, so that the functions of vision correction, protection, fashion and the like are provided.
However, the common lens has simple raw materials and relatively simple structure, has no great effect on the absorption and reflection of infrared rays and ultraviolet rays, and can damage eyes after being worn for a long time. Recent studies have shown that infrared and ultraviolet rays cause damage to the eyes of a person, such as the eyes of a person may cause damage to the retina of the fundus, and the eyes of a person may cause cataracts if exposed to infrared rays for a long period of time; the ultraviolet rays can cause cataract, keratitis, retina damage, cataract, macular degeneration, snowblindness and other serious eye diseases. It is therefore desirable to have glasses that protect and correct vision while also avoiding eye injury. Thus, lenses having various functions of preventing infrared rays, ultraviolet rays and blue light are appeared in the market.
With the development of technology, most of the glasses have more or less infrared or ultraviolet blocking functions, and generally, films for blocking ultraviolet and infrared are formed on the lens body respectively to form the lens. Meanwhile, in order to improve the protection effect, a mode of overlapping multiple films is generally adopted, for example, an infrared ray-proof, blue light-proof and ultraviolet-proof lens and a preparation method thereof, which are mentioned in Chinese patent No. CN109655943A, are overlapped by more than 6 films. But this way, while blocking infrared rays and infrared rays, the transmittance of visible light is reduced, which is unfavorable for vision correction and vision protection. Meanwhile, the current uv protection layer generally adopts organic matters with uv absorption (UVA) effect, and the organic matters have low melting point and cannot be directly used as a film layer, so that the organic matters need to be prepared into polymers to raise the melting point, so that the organic matters are not damaged due to environmental temperature rise in daily use. However, the ultraviolet absorption capacity of the polymer is reduced after the polymer is prepared, and the prepared polymer usually has a certain color and further influences the light transmittance. There is therefore a need for a better optical lens that is resistant to infrared and ultraviolet light.

The ultraviolet light-absorbing film solves the problems that the light transmittance is affected due to excessive coating layers in the prior art, and meanwhile, the organic film layer serving as the ultraviolet protective layer is required to be prepared into a polymer due to lower melting point, so that the absorbing capacity of the organic film layer is reduced.

In the prior art, if a non-polymeric organic matter with a lower melting point is used for preparing the ultraviolet absorption layer, when the temperature is higher, the ultraviolet absorption layer is softened, so that the whole film coating mechanism is displaced and damaged.

In addition, on the basis of using high-concentration ultraviolet absorbing organic matters, a plurality of layers of coating films are not needed to improve the absorption effect, the number of coating film layers is reduced, and the problem that the light transmittance is affected is correspondingly improved.
