Lens with anti-fog function

Abstract

The invention provides a lens with an anti-fog function, and particularly relates to the field of anti-fog lenses, which comprises a lens substrate provided with an anti-fog coating. The anti-fog coating is a hygroscopic polymer coating or a hygroscopic polymer and inorganic material cross-linked coating or a hygroscopic polymer and polymer cross-linked coating or a hygroscopic polymer and inorganic material mixed coating. The lens has a good anti-fog function.

Description

technical field [0001] The invention belongs to the field of anti-fog lenses, in particular to an anti-fog lens. Background technique [0002] Anti-fog mirrors are lenses that can effectively prevent or avoid condensation of water mist, and are generally divided into organic anti-fog mirrors and inorganic anti-fog mirrors. Inorganic anti-fog mirrors generally paste a layer of anti-fog film on the surface of the glass to achieve the purpose of anti-fog; anti-fog mirrors are lenses that can effectively prevent or avoid water mist condensation, and are generally divided into organic anti-fog mirrors and inorganic anti-fog mirrors. mirror. Inorganic anti-fog mirrors generally paste a layer of anti-fog film on the surface of the glass to achieve the purpose of anti-fog. Organic anti-fog lenses are divided into coated anti-fog lenses, electric heating anti-fog lenses and nano-composite anti-fog lenses.

AI Technical Summary

Problems solved by technology

There are two reasons for lens fogging: one is the liquefaction phenomenon caused by the hotter gas in the lens meeting the cooler lens; the other is the evaporation of water on the skin surface sealed by the silver mirror, and the condensation of the gas on the lens; The anti-fog performance of lenses with anti-fog function still needs to be further improved;
