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...

Embodiment 2-5

[0045] This embodiment 2-5 provides a preparation method of a color blindness and color weakness correction lens, the steps of which are the same as those of embodiment 1, please refer to Table 1 for the differences.

Embodiment 6

[0049] This embodiment provides a method for preparing a color blindness correction lens, which is the same as step (1) and step (2) in Example 1, except that step (3) is different, as follows:

[0050] Step (3) Add 1.41g HEMA, 0.3g NVP, 0.03g EGDMA, 0.02g AIBN, 6g ethylene glycol, 2.16g water in another container, stir at room temperature for half an hour to fully mix, and get HEMA-NVP water Gel precursor. Then add the above nanoparticles, stir to fully mix the nanoparticles and the solution, and ultrasonically disperse the nanoparticles in the HEMA-NVP hydrogel precursor for 15 minutes to obtain a mixed solution, then pour the mixed solution into a mold, and heat it at 70°C The HEMA-NVP hydrogel is cured by heating for five hours or under the catalysis of ultraviolet light, and the cured hydrogel is taken out from the mold to obtain a color blindness and color weakness correction lens.

Abstract

The invention discloses a color blindness and color weakness correction lens and a preparation method thereof, belonging to the field of optical materials. The corrective mirror includes a base lens and nanoparticles mixed in the base lens, the nanoparticles include a metal nano-core capable of generating surface plasmons and a film shell wrapped on the surface of the metal nano-core, the film shell The surface of the metal nano-core is wrapped by the self-polymerization reaction, and the size of the metal nano-core is preset, and the size of the metal nano-core corresponds to the target spectral range to be filtered out of the correction mirror. The present invention can achieve precise narrow-band absorption in the spectrum by adjusting the size of nanoparticles doped into the base lens, thereby solving the problem that the existing color blindness correction glasses cannot achieve accurate color filtering according to specific color blindness conditions, and the effect of color vision correction Limited technical issues.

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...
