Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1, the present invention discloses an antistatic PA lens, which comprises a substrate 1 made of PA12 (polydodecalactam), wherein the refractive index of the substrate 1 is 1.52, the light transmittance is 92%, the abbe number is 52, and the density and specific gravity are 1.02. The surface and the back of the substrate 1 are both provided with strengthening layers 2, the AR layer 3 is arranged on the outer side of the strengthening layer 2 on the back of the substrate, and the first titanium pentoxide layer 4, the first silicon dioxide layer 5, the second titanium pentoxide layer 6, the second silicon dioxide layer 7 and the antistatic layer 8 are sequentially arranged on the outer side of the strengthening layer 2 on the surface of the substrate. Wherein the antistatic layer 8 is a titanium oxide layer, and the titanium oxide layer may comprise a mixture of titanium pentoxide and niobium pentoxide. The titanium oxide layer may be a plating film of LUMILEAD TNO.

The first titanium pentoxide layer was 0.5 QWOT (1/4 wavelength was 1 QWOT), the first silicon dioxide layer was 0.23 QWOT, the second titanium pentoxide layer was 2 QWOT, the second silicon dioxide layer was 1QWOT, and the antistatic layer was 0.22 QWOT.

Because the base material adopts PA12, the impact resistance and the chemical stability of the base material are excellent, the PA12 lens material is applied to sunglasses and sports glasses, the combination of comprehensive properties and high comfort can be achieved, the weight is super light, the mechanical property and the high durability are excellent, and the service life of the lens can be prolonged. And the PA nylon 12 lens also has excellent stress cracking resistance and fracture resistance, is very suitable for being carried in outdoor activities or sports, can adapt to any material of the frame, and is not limited by the shape of the lens and the material of the frame.

In addition, each strengthening layer 2 is added on each side of the lens substrate 1, so that the hardness of the lens can be increased, the surface of the lens is protected, and meanwhile, an interface is generated before vacuum coating of high and low refractive materials is carried out, so that the adhesive force and the bonding strength are increased, and subsequent materials can be completely covered and stacked with film layers. The AR anti-reflection electroplating film layer can be added on the back surface of the lens, so that the reflection of the lens can be effectively reduced, the transmittance of the lens is increased, and the original color of the lens is brighter and more real.
