Description
The invention belongs to method, instrument and the achromatopsia glasses that is used to correct colour blindness of test colour blindness.
Red, orange, yellow, green, blue or green, blue, purple has constituted the multicoloured world, and why people can experience the fine of the world, and life gorgeous colorful is a kind of unique physiology reflection-colour vision by means of the eyes photic stimuli.Yet, the colour anomaly of people more than 200,000,000 is but arranged in the world, they have lost the correct identification capacity to color, are commonly called as colour blindness.Colour blindness is a kind of heredity physiological defect, and one to being considered to " incurable disease ".Achromate's misery be ordinary person's observation less than.Because most specialties all have strict demand to colour vision, the scientific worker has invented panoramic colour vision plates and chromatoptometry instrument miscellaneous.In enrollment, pre-employment physical, chromatoptometry is classified as essential items for inspection.One and be identified and suffer from colour blindness, they will be deprived the right of work such as being engaged in art designing, printing and dyeing, chemical industry, traffic, geology, medicine and national defence throughout one's life.Cause hundreds of millions achromates urgently to wish to have a kind of effective antidote, have fantasies of putting on a kind of special glasses, can equally enjoy the multicoloured boundless universe, obtain equal to enter a higher school, job opportunity with the normal person.
Think about the theory of colour blindness reason at present: " people's retina cell is divided into three kinds of awls of red, green, blue alms bowl cell.Cone pigment in these cells can only be felt its distinctive spectrum respectively and it is absorbed, so-called colour anomaly, and having a kind of in three kinds of cone pigments is congenitally just not have, people are its protanopia or second colour blindness.This situation is two colour pattern colour visions.If two kinds of cone pigments are all normal, another kind of pigment does not have, but and normal somewhat little difference, just be called anomalous trichromatism, just so-called anomalous trichromatism ".As if this theory is only summed up in the point that the reason of colour anomaly on the retina cell, also be ill-considered.Strictly speaking, also should consider information is passed to the neurocyte of brain cell, and whether brain cell itself is normal.
Can colour blindness be controlled still uncurable disease? can colour blindness is rectifiable still be rectified down? seek answer over more than hundred year in issue always.Aspect the colour blindness treatment, with headed by Japan medical science doctor Taketoshi Yamada and utilize the new technology of modern Medical Electronics with doctors'associations, create the point stimulating therapy (Just, Point, Just Channel) of a kind of being called " JPIC ".It is reported and obtained tangible curative effect.Aspect the rectification of colour blindness, Chinese patent 88200988, the protanopia anerythrochloropsia glasses of Chen Xiaoguang design were once disclosed, 87214130 disclose a kind of anomaloscope of Zhao Wenqing design, United States Patent (USP) 4300819, Deutsche Bundespatent 3209655 and Jap.P. 59-148027 have all reported achromatopsia glasses, but great majority are because calibration result is poor, or outward appearance is not beautiful, and does not form commodity.
As is generally known, no matter to treat still and correct, the diagnosis of colour blindness needs, and popular colour blindness inspection technique has following four classes:
1. charts for testing color perception,pseudo-isochromatic
A. the former formula charts for testing color perception,pseudo-isochromatic of stone
B. Tokyo medical university formula charts for testing color perception,pseudo-isochromatic
The pseudo-same color table of C.HRR
D. De Guo Fa Erpeisai-Si is for the pseudo-same color table of woods
2. hue discrimination device
A. color disk D15 inspection technique
B. hue discrimination detector
3. magic lantern inspection technique
4. anomaloscope
Chinese patent 88107043.2 discloses a kind of " objective detector for colour sense ", as a kind of objective determination method, the various subjectiveness and objectiveness inspection techniques that patent report is crossed have been enumerated in this invention, and made certain evaluation, really collection diagnosis and rectification are one, it is the disclosed Chinese patent 90200939.7 of Chen Xiaoguang, this utility model is designed a kind of colour blindness diagnosis and is corrected detector, it has concentrated achromatopsia checking figure, color contrast, the advantage of detection methods such as magic lantern is by man-machine conversation, to every group of colour vision plates random call, for the preparation achromatopsia-correcting glasses provides accurate data and correction curve and suitable prescription, and printing the classification of colour blindness, the photosensitive curves of step etc. have guaranteed the quality of chromatoptometry.
The present invention sets up mathematical model and expert diagnostic system according to human body physiological characteristics and colour blindness formation theory, and purpose provides the systems engineering of a kind of objective detection, diagnosis, rectification colour blindness and is the required achromatopsia glasses of rectification colour blindness.
The systems engineering that the present invention corrects colour blindness has broken through the classic method of colour vision mechanism research, derive the mathematical model of colour vision process and realized computer simulation, on the basis of colour vision and colour blindness topology research, set up colour anomaly catastrophic model and colour vision information and transmitted the communication line block diagram; By the computer simulation of colour blindness, realized quantitative and qualitative research that colour blindness and colour blindness are corrected, finished the mensuration of colour blindness correction curve, and, provided the spectral characteristic data of the achromatopsia-correcting glasses of 32 grades of four classes according to the result of this research.Do according to result of the present invention, the patient is by computerized optometry, and system provides the spectral characteristic data of suitable its rectification, makes glasses in view of the above, can make colour blindness be tending towards normal.
A large amount of clinical detection prove that the string person overwhelming majority who is diagnosed as protanopia anerythrochloropsia can tell the red, green, blue three primary colours still for the trichroism colour vision, and is just quite low to the colouring discrimination ability in some wavelength coverage.According to human colour vision process is the viewpoint that a kind of point-to-point Topological Mapping and physiology course have structural stability, and the mathematical model of colour vision process has been set up in systems engineering of the present invention.The foundation of this colour vision process mathematical model is: the colour blindness origin cause of formation mainly is achromate's the neat caused by abnormal of color sign indicating number: the one, in retina, chromatic information is carried out in the compressed encoding matrixing, because it is unusual that a certain pigment receives information, cause the out of proportion of monochrome information amount that gangliocyte spreads out of and chrominance information amount; The 2nd, when surveying geniculate body outside and carrying out the decoding matrix conversion, a certain confluent monolayer cells property abnormality, cause to the cerebral cortex vision area to look emittance out of proportion; The 3rd, cerebral cortex vision area cell function is unusual, causes the color sign indicating number unusual together.Experimental results show that the colour anomaly no matter any reason causes, as long as change the values ratio of three kinds of cone cells from the outside, it is neat all can to reach change cerebral cortex vision area color sign indicating number, thereby improves the purpose of chromatic discrimination power.
Among the present invention, the unusual mathematical model of colour blindness that we propose is:
According to standard red (R), green (G), blue (B) cone cell spectral absorption peak value, determine that respectively the subordinate function of its subclass is:
λ is a predominant wavelength in the formula, R
Max, G
Max, B
MaxBe respectively honeybee value wavelength, a

B（B）
U＝Ku（R-L）
V＝Kv（B-L）
Wherein L is a luminance signal, and U is red degree signal, and V is blue degree signal, and Ku, Kv are weighting coefficient.
More than three kinds of signals be transferred to respectively in pregeniculate six layer tissues by optic nerve fiber and go, conversion decomposites R, G, three kinds of primary colour signals of B through Differential Topology again:
R＝V/Kv+L
G＝（L-L

Via looking radiation delivery to the cerebral cortex vision area.
Cerebral cortex is to the scale-up factor of three primary colours
Carry out analysis-by-synthesis, make Y(c) → t(c), promptly produce a colored consciousness to external world.Y(c in the formula) is form and aspect, t(c) is colour vision.The Cusp Catastrophe Model of the colour vision behavior state variable that we propose is:
f（L）＝L
4+UL
2+VL
In the formula: L is a luminance signal, and U, V are respectively red degree signal and blue degree signal.
The present invention detects expert system by colour blindness above-mentioned model is simulated, colour blindness is corrected flow process as shown in Figure 1, and it is corrected colour blindness rafractive and constitutes (as shown in Figure 2) 1, microcomputer, and 2, the color card of high-resolution, 3, high-resolution enhancement mode color monitor, 4, printer.The software systems block diagram is seen Fig. 3.Microcomputer adopts AST-206(or other compatible), expert system comprises the neat chart of color sign indicating number of colour blindness, three primary colours adjustable ratio Control Software and colour blindness diagnosis corrective prescription software.The color card of the high-resolution that uses among the present invention is colour/graphic monitor adapter, and as the CRT control device, this adapter is more suitable for programming with respect to grating and character properties to critical piece by 6845 chips.It also provides necessary interface and the display buffer (64KBTES) that drives the CRT raster scanning, cooperates character generator simultaneously, timing generator, and colorflexer, the color card of high-resolution is formed in the support of circuit such as synthetic color generator.
The high-resolution display can adopt the CASDER display, and printer adopts Brotter-1724.
