Abstract
The present invention establishe the color sense anomaly formation theory and model according to the trichromatic theory and existing color sense anomaly expression, and gives the corrective curve of color sense anomaly to different patient, and makes corrective glasses according to said corrective curve.
Description
The invention belongs to the detection and the correcting spectacle lens of color anomalopia chromatopsia.
We live in the colorful in riotous profusion natural world, and people are reflected the world of working energetically of experiencing WANZIQIANHONG by this physiology of color vision.But because this heritability physiological defect of color anomalopia chromatopsia, make existing in the world people more than 200,000,000 lose correct identification capacity, and deprived, enjoy the right of colorful life with the same study of normal person, work to color.For this reason, the scientist of countries in the world is seeking to cure and correct the method for color anomalopia chromatopsia always.
United States Patent (USP) 4300819, moral enclose patent 3209655, and Japan Patent 59-148027 has all reported anomaloscope, Chinese patent 87214130,88200988 disclose again the Zhao Wenqing design achromatopsia glasses.
The objective of the invention is performance situation according to three-primary colours academic theory and existing color anomalopia chromatopsia, set up color anomalopia chromatopsia formation theory and model, provide different patients' color anomalopia chromatopsia correction curve, and make correcting spectacle lens thus, reach the rectification purpose of color anomalopia chromatopsia.
Content of the present invention:
Three-primary colours theory in the theories of vision is thought, normal eye's color vision is that three kinds of incoherent color receptors are arranged in the three parameter human eyes, three kinds of color receptor sensitivity response curves of the normal person who is gone out by color reaction device theoretical calculate that this has been proved by objective experiment are shown in figure (1), and its equation is:
F1=0.2343X+0.8200Y-0.05429Z
F2=-0.4457X+1.3748Y+0.09205Z
F3=1.0000Z
Wherein F1, F2, F3 are the color reaction degree of three kinds of color receptors, and X, Y, Z are chromaticity coordinate.
For color anomalopia chromatopsia person, the sensitivity response curve of his three kinds of color receptors is different with the normal person, according to color anomalopia chromatopsia person's different manifestations situation and above-mentioned three-primary colours academic theory, proposes the formation theory and the model of following color anomalopia chromatopsia.
First type color anomalopia chromatopsia shows as: see spectral color, long-wave band is yellow, and short-wave band be a blueness, to spectrum red end vision especially a little less than, distinguishable Huang, blue dichromatism can not be differentiated red, green.Deducibility thus, the spectrum sensitive response curve of its color receptor are shown in figure (2), and it is low than the normal person that the red light sensitiveness curve receives peak value, and its peak change is from O---and normal.
B-mode color anomalopia chromatopsia shows as: see spectral color, long-wave band is yellow, and short-wave band is blue, and is not poor to the visual sensitivity of spectrum red end, but poor than the normal person to red, green discriminative power, distinguishable Huang, blue dichromatism.Deducibility thus, the spectrum sensitive response curve of its color receptor shown in figure (3), the green light sensitive curve receive peak value than normal person's height,
The third type color anomalopia chromatopsia shows as: see spectral color, long-wave band is red, and short-wave band is an aeruginous, and is distinguishable red, green, can not differentiate Huang, blue dichromatism.Go out this deducibility, the spectrum sensitive response curve of its color receptor is shown in figure (4), and the sensitive to blue light curve receives peak value and surpasses the normal person.
Fourth type color anomalopia chromatopsia shows as: see spectral color, long-wave band is red, be green near the 580um, short-wave band is again red, distinguishable red, green, can not differentiate Huang, blueness, deducibility thus, the spectral sensitivity curve of its color receptor is shown in figure (5), and it is lower that promptly blue sensitivity curve receives peak value, and its peak change is from O---and normal.
Formation theory and model according to above color anomalopia chromatopsia, can change the spectrum sensitive response curve of color anomalopia chromatopsia person's color receptor by specific spectral pattern, make the ratio of reception peak value of its three kinds of receptors identical, reach the purpose of correcting color anomalopia chromatopsia with the normal person.The spectral pattern that to correct color anomalopia chromatopsia according to the rectification type of color anomalopia chromatopsia is divided into following four kinds:
