Description
Technical Field
The utility model belongs to the technical field of the lens, relate to the resin lens, especially, relate to an antifog photochromic resin lens.
Background
Compared with inorganic glass lenses, resin lenses are gaining more and more favor of consumers by virtue of the advantages of light weight, good toughness, low price and the like. However, people often suffer from the problem that the lenses are easy to fog in the process of wearing the glasses, and particularly, fog drops are easy to appear on the inner surfaces of the lenses when the glasses are worn on a mask or used for swimming, so that the sight of a wearer of the glasses is greatly influenced. In addition, the eyes of people are easy to generate visual fatigue in a strong light environment, and the photochromic lens can meet the requirement of people on reducing the optical strength outdoors.
At present, single-function lenses capable of achieving fog prevention or color change exist in the market, but products capable of achieving the two functions well do not exist, and especially under the condition that a mask is worn outdoors, the two functions of fog prevention and color change are needed.
CN106405691A discloses an antifogging optical resin lens and a preparation method thereof, wherein an anti-reflection antireflection film layer and a macromolecular hydrophilic film are bonded together through optically transparent glue, so that the transmittance of light is increased and the reflectance of light is reduced on the basis of not influencing the original function of the resin lens, the resin lens has new antifogging performance, and the refractive index of the resin lens is not influenced. Therefore, the resin lens has stronger functionality and better market prospect. However, the gluing method has the problems of weak adhesion and limited service life; in addition, the product of the optical resin lens for preventing is single in function, only has an anti-fog effect but has no photochromic function.
CN106772707A discloses a preparation method of a blue-light-proof antifogging coated resin lens, wherein silicon oxide, zirconium oxide and indium tin oxide are respectively deposited by vacuum coating, so as to achieve the effects of anti-reflection, anti-reflection and blue-light prevention, and the blue-light absorption rate (380 nm and 500nm) of the lens prepared by the preparation method reaches 25 percent; before the anti-fog film layer is plated on the anti-blue light film, the silicon oxide is subjected to surface treatment by using plasma to activate the hydrophilicity of the anti-fog film layer, and then the anti-fog film layer is dip-coated with the organic silicon modified hydrophilic resin anti-fog coating, so that the adhesive force of the anti-fog film layer is increased, and the anti-fog film layer can be cured at normal temperature. The resin lens prepared by the preparation method not only has the blue light prevention performance, but also has the antifogging performance, and has the advantages of more comprehensive functions, strong practicability and large market potential. However, such lenses do not have photochromic functionality and need to be further improved.
CN109116582A discloses a photochromic resin spectacle lens and a manufacturing method thereof, firstly, the manufacturing method utilizes the migration property of a color-changing substance by arranging a front protective layer, so that more color-changing powder has the tendency of inward migration, and the activity of the color-changing substance can be ensured because the front protective layer is softer; in the manufacturing method, the post-positioned protective layer is provided to prevent the damage of the discoloring substance caused by the intrusion of the hard reinforcing layer. Thus, the original dimming performance of the photochromic layer is better protected through different action effects of the two aspects, so that the faster photochromic effect and the longer service life are realized. However, this method can only perform one function of photochromism. And the lens surface is softened by the symmetrical multi-layer design of the front and back surfaces and is difficult to combine with a thicker antifogging functional hard coating.
CN204855971U discloses a photochromic prevents blue light resin lens, it has fused the function of discolouing and has prevented the blue light function, photochromic prevents blue light resin lens except having the original function of correcting the eyesight of lens, can filter the harmful blue light that emits out in cell-phone screen, panel computer screen and the notebook computer screen for people again. Moreover, the photochromic blue-light-proof resin lens can realize quick color change under outdoor conditions by arranging the photochromic layer, block strong sunlight for people and prevent dizziness and transient blindness caused by strong light irradiation; meanwhile, the multifunctional outdoor mirror can be used as a necessary ornament for outdoor travel of people as a sunglass. However, the lens also has no antifogging function and needs to be further improved.
Therefore, how to combine the antifogging function and the photochromic function of the lens and ensure that the two functions are not influenced mutually, the original good effect of each function is maintained, and the problem which needs to be solved at present is provided.

From the above table, it can be seen that: the antifogging photochromic resin lenses provided by the embodiments 1 to 5 have good light transmittance after discoloration, and antifogging properties pass the test; the resin lens provided in comparative example 1 failed the antifogging property test because it did not have the antifogging coating; comparative example 2 provides a resin lens having an antifogging coating but disposed on the outside of the lens rather than the inside, so that the initial antifogging property test was passed but the permanent antifogging test was not passed.
Therefore, the utility model provides an antifog photochromic resin lens can realize antifog and two functions of photochromism and each other do not influence simultaneously, keeps the original good effect of each function, and initial antifog performance and lasting antifog performance all show excellently, and the luminousness generally maintains about 20% after discolouring. Particularly, in the case of wearing a mask, the inner surface of the lens is a main fogging region, and the fogging coating is provided on the inner surface of the lens, whereby fogging of the lens can be prevented more directly and effectively.
The applicant states that the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that any changes or substitutions easily conceivable by those skilled in the art within the technical scope of the present invention are within the protection scope and the disclosure scope of the present invention.
