Preparation method of organic/inorganic nano composite microsphere optooptic material

Abstract

The invention relates to a preparation method of an organic/inorganic nano composite microsphere optooptic material, wherein the preparation method comprises the steps: I, weighing an acrylate monomer, a spiropyrane compound represented by a formula (I) and transition metal oxide nanoparticles according to a mass ratio of (1-2):(2-3):(2-4); II, adding an emulsifier, transition metal oxide nanoparticles and a sodium acetate saturated aqueous solution into water; III, adding a cross-linking agent into the reaction system, introducing nitrogen, and adding a spiropyrane compound solution; and IV, adding an acrylate monomer, adding an initiator at the temperature of 65-90 DEG C, carrying out heat preservation polymerization for 12-18 hours, filtering, washing and drying. The material prepared by the method is of a three-layer composite core-shell structure, and can be added into a resin optical material or an optical lens as a light-filtering color-complementing material. The lens material is dark in color under indoor normal light, can automatically enhance the spectral color purity of a certain wave band and the dimension of a color vision vector space, improves the color discrimination ability of a color blindness patient, and corrects color vision abnormality.

Description

technical field [0001] The invention belongs to the technical field of ophthalmology and optics, and in particular relates to a preparation method of a color vision correction optometry material. Background technique [0002] Color vision is one of the important visual functions of the eye. The seven colors of the visible spectrum in sunlight can be attributed to the three primary colors, namely red, green and blue. Retinal cone cells contain red, green and blue pigments. The human eye can recognize more than 100 different colors. Congenital abnormalities of color vision are caused by an abnormal lack of chromogenic pigments in cone cells. It can usually be divided into panchromatopsia, red-green color blindness and red-green color blindness. Monochromatic vision with only one color-sensing pigment, that is, panchromatic vision; people with two color-sensing pigments are dichromatism, and those who lack red-sensing or green-sensing pigments are red-green color blindness; t...

But in this way, some people can rely on the difference in brightness to distinguish "color" when they don't wear traditional color-blindness correction glasses, but they can't distinguish when they wear this kind of color-blindness correction glasses.

Not only that, but people who wear traditional color-blindness correction glasses will always have some decline in overall vision, and the bright red and green appearance is also unacceptable
