The invention discloses a resin eyeglass, a lens anti-
fog device, a preparation method and applications thereof. The resin eyeglass comprises a resin substrate, a priming layer, a
bedding layer, a conductive layer, an anti-oxidation layer, and a protective layer, wherein the priming layer, the
bedding layer, the conductive layer, the anti-oxidation layer, and the protective layer are adhered on the resin substrate in sequence, the priming layer is a
silicon monoxide film with a thickness of 10 to 20 nm; the
bedding layer is a
zinc oxide film, a
titanium film or a
nickel-
chromium alloy film; the conductive layer is a conductive
metal film with a thickness of 5 to 15 nm; and the anti-oxidation layer is an anti-oxidation material film with a thickness of 1 to 5 nm. The lens anti-
fog device comprises one provided resin eyeglass, a positive
electrode, and a negative
electrode, wherein the positive
electrode and the negative electrode are arranged on two ends of the resin eyeglass respectively. The provided resin eyeglass has the advantages of good electro-conductive performance, anti-reflection effect, and anti-oxidation effect, moreover, the preparation method is simple, the production efficiency is high, and the yield of plating is high. The provided lens anti-
fog device can be connected to a power supply to heat the film so as to prevent water steam from forming fog on the surface of lens.
