Abstract

The invention discloses a pair of color blindness and color amblyopia correction glasses and a preparation method thereof, and belongs to the field of optical materials. The correction glasses comprise a substrate lens and nanoparticles mixed in the substrate lens, each nanoparticle comprises a metal nanometer core capable of generating surface plasma and a film shell layer wrapping the surface of the metal nanometer core, and the film shell layer wraps the surface of the metal nanometer core through self-polymerization reaction. The size of each metal nano-core is preset, and the size of the metal nano-core corresponds to a target to-be-filtered spectrum interval of the correction mirror. According to the invention, accurate narrow-band absorption can be realized on the spectrum by adjusting the size of the nanoparticles doped into the substrate lens, so that the technical problems that the existing color blindness correction glasses cannot realize accurate color filtering according to the specific color blindness condition and the color vision correction effect is limited are solved.

Description

technical field

[0001] The invention belongs to the field of optical materials, and more specifically relates to a color blindness correction lens and a preparation method thereof. Background technique

[0002] At present, there is no mature cure for color blindness and color weakness clinically. Therefore, color blindness and color weakness correction glasses, which mainly wear color filters, are the only choice for most color blindness and color weakness patients to distinguish colors. And the existing color-blindness and color-weakness correction glasses mainly adopt the method of coating and adding pigment, filter out the band that the patient can't distinguish clearly, and enhance the color contrast. The coating method produces a cut-off wavelength effect by applying a special coating on the lens, which can transmit the long-wavelength lens and scatter the short-wavelength lens, thereby achieving the effect of correcting color vision impairment. Although this coating m...
