For example, will occur on the surface of the medium boundary reflection of light, so the light immediate illuminate is on will affect the light transmittance of optical lenses, optical lenses In addition, in the process of long-term use, optical lens will inevitably contact with other material to produce friction, and thus reduce the resolution of optical lenses, also reduce the service life of optical lenses. Therefore, how to improve the light transmittance of optical lenses, increase the optical lens wear-resisting fouling resistance and other issues has become a hot topic in the industry research. 【 Utility model content 】 ( 0003] In order to solve the above problems, the optical lenses, in glass substrate surface is set up and multi-layer nanometer silicon dioxide thin film and multilayer nano titanium dioxide thin film, using multilayer thin film optical interference, increase the light transmittance, at the same time set up the fingerprint antifouling nanometer layer, invisible anti-counterfeiting and potassium ion hardening layer, make the optical lens separated oil, fingerprint resistant, scratch resistant, anti-aging, anti-fake, etc. ( 0004] Of the technical scheme of the utility model is: A kind of optical lenses, including glass substrate, described in the glass substrate surface and under surface have film system, whose character is: the glass substrate above the mask is described in turn from top to bottom of A fingerprint resistant antifouling layer, nano silicon dioxide layer, nano titanium dioxide layer A, described under the glass substrate surface film system from top to bottom in turn to invisible anti-counterfeiting, nanometer titanium dioxide layer B, nanometer silicon dioxide layer B and potassium ion hardening layer, nano titanium dioxide, A nanometer silicon dioxide layers described A, B and nanometer titanium dioxide nano silicon dioxide layer B are multilayer thin film structure.
