Anti-oxidation, anti-reflection and corrosion-resistant lens and preparation method thereof

Abstract

The invention relates to an antioxidation antireflex corrosion-resistant lens and a preparation method thereof. The lens comprises a resin substrate and a film layer arranged at the inner surface of the resin substrate; the film layer comprises seven thin film layers which are sequentially stacked from inside to outside and respectively include a silicon-aluminum mixture, nickel-chromium alloy, titanium oxides, a silicon-aluminum mixture, nickel-chromium alloy, a silicon-aluminum mixture and a waterproof layer. The average reflectivity of the prepared antioxidation antireflex corrosion-resistant lens on the wavelength being 400 to 700nm is smaller than or equal to 0.56 percent; the reflection light intensity is effectively reduced; the generation of dazzle light can be prevented; the lighttransmittance is increased; the eyes of a wearer are effectively protected; the antioxidation and corrosion-resistant effects are achieved; the service life is long; the controllability of the preparation process is high; the process can be completed by common operators; good market prospects are realized.

Description

technical field [0001] The invention relates to a functional lens, in particular to an anti-oxidation, anti-reflection and corrosion-resistant lens and a preparation method thereof. Background technique [0002] Anti-reflection lenses usually include multiple film layers. The light waves reflected from one layer will be offset by the light waves reflected by the other layer. The film layer reduces light reflection and increases light transmittance. On the one hand, it can reduce glare and avoid glare. Disgust, discomfort or even loss of vision, such as glare spots on sunglasses, and the obvious glare caused by oncoming headlights when driving at night, on the other hand, due to the increased ratio of transmitted light / reflected light, it can make The image is clearer. [0003] Invention patent CN105359005B discloses an optical article with an antireflection coating with extremely low reflection in the visible region, comprising a transparent substrate with a front main surf...
