Embodiment 1

[0040] This embodiment provides a preparation method of color blindness and color weakness correction lens, see figure 1 , the steps are as follows:

[0041] (1) Prepare KH590 solution: dilute 20.3ul KH590 with alcohol to 10ml for later use; prepare a total of 2ml of TEOS ethanol solution with a volume fraction of 20% for later use.

[0042](2) Pour 40ml 0.5mmol / L size of 20nm gold nano-nucleus dispersion liquid into the container, the dispersion liquid is the aqueous solution of CTAB, after the dispersion liquid is ultrasonically dispersed for ten minutes to make it fully dispersed, add 800ul 0.01 mol / L KH590 solution was stirred at room temperature with a magnetic stirrer at 3000 rpm for five hours to fully react to form Au-S bonds on the surface of the Au nano-core. Then add 200ul of TEOS ethanol solution with a volume fraction of 20% to the container, then add an appropriate amount of ammonia water to adjust the pH of the solution to between 10 and 11, and continue stirri...

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...
