Problems solved by technology

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

Abstract

The invention relates to a preparation method of a color vision correction resin lens, wherein the preparation method comprises the steps: I, preparing an organic / inorganic nano composite microsphere which is of a three-layer composite core-shell structure, wherein an inner core of the microsphere is an oxide nano microsphere, the middle layer of the microsphere is a color complementing layer formed by a spiropyrane compound, and the outer shell of the microsphere is acrylate; and II, adding the organic / inorganic nano composite microsphere into an acrylate monomer, and carrying out polymerization reaction to obtain the color vision correction resin lens. The lens is dark in color under indoor normal light, and can automatically enhance the spectral color purity of a certain wave band and the dimension of a color vision vector space, improve the color discrimination ability of a color blindness patient and correct 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 correcting resin lens. 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; the color...
