Abstract
A pair of glasses for correcting abnormal chromatic sensation features that after the chromoprotein gene of retinal rod and cone cells for coded person has been separated and determined, the optical film ont he lenses is processed for redistributing visible spectrum energy and modifying the sdaturation threshold of visual pigment of colour anomalopia patient to correct the error code and mixed code in colour sense encode of retaina and in turn to correct abnormal chromatic sensation. Said glasses canb e falled in 3 kinds including 12 serieses for meeting different patients.
Description
The correcting spectacle lens of colour anomaly of the present invention is mainly used in colour blindness and anomalous trichromatism patient.
Colour anomaly (being commonly called as colour blindness) is the disease of a kind of X chromosome sex linked inheritance or autosomal dominant inheritance, has people more than 200,000,000 to suffer from this disease at present in the world approximately, brings many difficulties for their study and life.
The scientific worker of many countries in the last hundred years, constantly seeking treatment and rectification way, for example Deutsche Bundespatent 3209655, Jap.P. 59-148027, United States Patent (USP) 4300819, Chinese patent 88200988 disclose achromatopsia glasses, all bad because of rectification effect, wear inconvenience and fail to form commodity.
Purpose of the present invention is exactly energy distribution, red, the green saturation threshold of looking quick pigment of reduction that changes visible spectrum again, the colour vision of correcting a mistake coding, and the purpose of colour anomaly is corrected in realization.On optical glass lens, carry out the processing of film system, made 12 series of products of 3 classes, satisfy different patients' needs.
Rationale of the present invention: the colour anomaly correcting spectacle lens is according on the basis of having identified with the gene of rod cell that has separated the coding people and cone pigment opsin, finds the way of correcting colour vision.Because the carbon-to-carbon double bond of the opsin conjugation of colour anomaly patient's genetic institute specialization how much, differs from the normal person, thereby it is different with the visual pigment saturation threshold to cause absorption peak to change.The protan carrier is to redness, and the deutan carrier rises (Wieland, 1933) to the saturation threshold of green, is the main cause that causes colour anomaly.
According to Soviet Union La Pujin classification is reference, and we are divided into 3 classes with colour anomaly: the NA class is red color weakness and red-bindness, and the NB class is deuteranomalia and deuteranopia, and the NC class is that yellow cyan is weak and yellow cyan is blind.
Above-mentioned every class is divided 4 gradients again, is used for changing the values of the light-change of visual pigment concentration in various degree, to be fit to the patient of different colour anomaly degree, reaches best rectification effect.
Adopt vacuum optical coating technology, available homemade or import optical vacuum coating machine on optical lens, according to totally 12 kinds optical film design the carrying out multilayer optical film processing of 3 classes, is finished the making of correcting the colour vision lens.
3 classes are totally 12 kinds of lens films system processing designs of correcting colour visions, are that the absorption peak wavelength transmitance according to four kinds of visual pigments of retinal photoreceptor is as the criterion, and its wavelength is 440nm, 497nm, 530nm, 560nm.
The NA class will reach following index in the transmitance at four wavelength places:
440nm place transmitance reaches 5%～30%, wherein 5%, 10%, 20%, 30% is divided into four gradients.
497nm place transmitance requires to reach 2%～40%, wherein 2%, 10%, 20%, 40% is divided into four gradients.
530nm place transmitance requires to reach 2%～30%, wherein 2%, 10%, 20%, 30 is divided into four gradients.
560nm place transmitance requires to reach 40%～70%, wherein 40%, 50%, 60%, 70% is divided into four gradients.
The NB class will reach following index in the transmitance at four wavelength places:
440nm place transmitance requires to reach 40%～80%, wherein 40%, 50%, 60%, 80% is divided into four gradients.
497nm place transmitance requires to reach 2%～30%, wherein 2%, 8%, 15%, 30% is divided into four gradients.
530nm place transmitance requires to reach 2%～30%, wherein 2%, 8%, 15%, 30% is divided into four gradients.
560nm place transmitance requires to reach 10%～50%, wherein 10%, 20%, 35%, 60% is divided into four gradients.
The NC class requires to reach following index in the transmitance at four wavelength places:
440nm place transmitance requires to reach 2%～30%, wherein 2%, 8%, 15%, 30% is divided into four gradients.
497nm place transmitance requires to reach 20%～50%, wherein 20%, 30%, 40%, 50% is divided into four gradients.
530nm place transmitance requires to reach 30%～60%, wherein 30%, 40%, 45%, 60% is divided into four gradients.
560nm place transmitance requires to reach 50%～70%, wherein 50%, 55%, 60%, 70% is divided into four gradients.
