the silicon dioxide layer is arranged on the front surface of the first transparent substrate.
Further, the thickness of the silicon dioxide layer is 10-200 nm.
Further, the thickness of the aluminum alloy layer is 20-150 nm.

Further provided is a specific material of the first transparent substrate and the second transparent substrate, wherein the first transparent substrate and the second transparent substrate are both made of glass.
After the technical scheme is adopted, the aluminum alloy layer is used in the conductive reflecting layer, so that the conductivity of the whole conductive reflecting layer is improved, and the aluminum alloy layer mainly plays roles of conduction and reflection. Compared with the prior art, the aluminum alloy is used for replacing silver alloy, and although the conductivity of the aluminum alloy layer is slightly poorer than that of the silver alloy, the aluminum alloy layer still has enough excellent conductivity, and the price of the aluminum alloy is much lower than that of the silver alloy, so that the cost is greatly saved, the production cost of the electrochromic lens is greatly reduced, and the popularization and application of the electrochromic lens are facilitated. The silicon dioxide layer is arranged between the aluminum alloy layer and the first transparent substrate to fill the hollow on the first transparent substrate, so that the front surface of the first transparent substrate is smoother, the absorption of the first transparent substrate to light can be reduced, and the transmittance and the reflectivity are improved; the silicon dioxide layer can also increase the adhesive force of the aluminum alloy layer. The first ITO layer is arranged to protect the aluminum alloy layer so as to prevent the aluminum alloy layer from being oxidized, and the defect that the aluminum alloy layer is easy to oxidize is overcome.
