The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention.

[0017] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 , Figure 1 It is a schematic diagram of the structure of the spin-coated color-changing layer of the anti-glare and impact-resistant lens according to an embodiment of the present invention.

[0019] As shown in the figure, a spin-coated color-changing layer structure of an anti-glare and impact-resistant lens includes: a hardened layer 20, which is dip-coated on the surface of a resin substrate 10; an anti-glare film 30 arranged on the surface of the hardened layer 20, the anti-glare film 30 has an interference structure, the interference structure is arranged as a base film layer, and a scale layer located on the upper side of the base film layer, the scale layer is composed of a plurality of reflective units arranged in mutual interference; an ultraviolet light-cured layer 40 spin-coated on the surface of the anti-glare film 30; and a photochromic layer 50 spin-coated on the surface of the ultraviolet light-cured layer 40.

[0020] In one embodiment of the present invention, the resin substrate 10 is formed by curing a resin monomer, and after curing and cleaning, it is put into a hardening liquid pool for hardening to form a hardening layer 20 for improving the surface hardness of the resin substrate 10. Preferably, the hardening layer 20 is set as an organic silicon film layer.

[0021] The anti-glare film 30 is vacuum-plated by silicon dioxide and nano zirconium dioxide, that is, silicon dioxide powder and nano zirconium dioxide powder are vacuum-plated in a coating machine in a ratio of 1:1, and the anti-glare film 30 is finally formed, and the interference structure is formed by a mold. The interference structure can be carved by ion bombardment using an electron gun.

[0022] Specifically, the anti-glare film 30 is composed of a base film layer and a scale layer. The scale layer is arranged as a fish scale structure, that is, a plurality of reflective units are arranged in an interference manner, and are tiled and stacked to form a fish scale shape, which can effectively enhance the reflection of stray light and enhance the anti-glare effect. In addition, a UV curing layer 40 is further spin-coated on its surface, which can further protect the anti-glare film 30, prevent it from being worn and oxidized, and enhance its impact resistance. The photochromic layer 50 is a photochromic material, which provides a photochromic effect for the lens, so as to adapt to the conversion of indoor and outdoor use, without the trouble of preparing sunglasses under high-intensity sunlight. In addition, the photochromic layer 50 cooperates with the anti-glare film 30, and the reflective units of the fish scale structure are photoinduced to change, forming a colorful style, which is more fashionable than the photoinduced change of a single color, and has a stronger anti-glare effect.

[0023] In a preferred embodiment, the end of the reflective unit is provided with a rounded corner, the transition is smooth, the shape is a block with an arc, and the rounded corner radius is less than or equal to 0.5 μm.

[0024] In a preferred embodiment, the photochromic layer 50 has different thicknesses on each reflective unit, thereby forming photochromic effects of different intensities, forming a fish-scale ripple light effect corresponding to the anti-glare film 30, and having a good effect in resisting stray strong light.

[0025] Furthermore, the thickness of the photochromic layer 50 decreases or increases gradually from the front to the back on the surface of the reflective unit, and the change is uniform. Under strong outdoor light, a gradual effect is formed, which is novel.

[0026] In addition, an anti-impact layer is also provided on the surface of the photochromic layer 50 to improve the impact resistance of the lens surface, and a silicon carbide film layer may be preferred.

[0027] In other embodiments, a silicon fluoride layer is further disposed on the surface of the photochromic layer 50 , and the fluoride layer can improve the waterproof and anti-fog properties.

[0028] In summary, the present invention forms fish-scale glare discoloration protection by providing an anti-glare film 30 with a fish-scale structure in combination with a photochromic layer 50, thereby improving the discoloration switching between indoor and outdoor environments, while reducing strong stray light interference and improving wearing comfort.

[0029] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
