Color vision correction resin lens

Abstract

A color vision correction resin lens comprises a lens resin base material and an organic / inorganic nanometer composite microsphere optooptic material, the optooptic material is of an acrylate / spiropyrane / transition metal oxide nanometer microsphere three-layer composite core-shell structure, the transition metal oxide nanometer microsphere serves as an inner core of the optooptic material, a spiropyrane compound shown in the formula I is wrapped outside the transition metal oxide nanometer microsphere. The shell is made of acrylate; the mass ratio of the transition metal oxide nano microspheres to the spiropyrane to the acrylate is (2-4):(2-3):(1-2). The optooptic material has light filtering and color complementing effects in the lens. The color of the lens is darker under normal indoor light, the spectral color purity of a certain wave band and the dimension of a color vision vector space can be enhanced, the color discrimination ability of a color blindness patient is improved, color vision abnormity is corrected, the lens can rapidly fade to be light or colorless when outdoors, and it is ensured that the patient looks true objects. The resin lens has the advantages of high color saturation, good color discrimination effect, comfort in wearing and the like.

Description

technical field [0001] The invention belongs to the technical field of ophthalmology and optics, and in particular relates to a color vision correction optical 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-sensing pigments in 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
