Abstract
A pair of glasses for correcting colour blindness features that on the both lenses, there are corresponding optical filter areas which have different filter characteristics to modulate the colour not to be discriminated by eyes into discriminable information mode, the filter device is used to modulate into different brightnesses on both lenses, so helping eyes to discriminate it and increasing the number of dimensions in colour vision vector space. Its advantages include high effect and no influence to normal application of glasses.
Description
The present invention relates to achromatopsia-correcting glasses or eyeglass and realize the antidote of this achromatopsia.
Traditional achromatopsia-correcting glasses all is the rectification that realizes achromatopsia by the amplitude-frequency characteristic that changes the eyeglass transmitance.In these achromatopsia-correcting glasses, two pairing light-filtering characteristics are identical.Though achromatopsia-correcting glasses can make the achromate see traditional achromatopsia checking figure clearly, can't resolve the problem of metachrosis.Still can not distinguish traffic lights such as most of patient, in essence, not only can not increase metachrosis, also disturb the normal part of vision, nor attractive in appearance.
According to the mankind's colour vision physiology and physics etc., normal person's color vision characteristics is the three-dimensional vector space, and three basic vectors are three primary colours of corresponding red, green, blue respectively.Each color can be expressed as a point or a vector in this vector space.This dimension of a vector space of achromate is lacked than the normal person, if the difference of certain two kinds of color only shows on certain dimension basic vector that certain achromate lacks, and when the difference in the brightness is not obvious (achromatopsia checking figure is principle according to this), this achromate just can not differentiate this two kinds of colors.Traditional achromatopsia-correcting glasses can not increase this dimension of a vector space, but changes the difference of these two kinds of colors in brightness, wear traditional achromatopsia-correcting glasses after the achromate rely on the difference in the brightness to differentiate this two kinds " color ".But so, also can rely on the difference in the brightness to tell " color " when having some not wear traditional achromatopsia-correcting glasses, can not differentiate again on the contrary when being with this achromatopsia-correcting glasses.Moreover, wear traditional achromatopsia-correcting glasses person, overall vision always has some and descends, and the image of bright red Folium Isatidis also is difficult to be accepted.
In view of the foregoing, the objective of the invention is to overcome the problem that traditional glasses can not increase patient's color discrimination in itself, to provide a kind of can make the achromate really increase chromatic discrimination power, not only can see the achromatopsia checking figure table clearly, but also can directly produce for " lose color " concrete achromatopsia-correcting glasses of experiencing and strengthen the method for color discrimination.
To achieve these goals, achromatopsia-correcting glasses of the present invention comprises: left eyeglass, right eyeglass, mirror holder, preparation has filter area respectively on two eyeglasses, makes two filter areas 3 and 4 on the eyeglass have different light-filtering characteristics.
The present invention strengthens the method for eyes color discrimination, the information mode that the unresolvable color modulation of eyes is become can differentiate.The present invention modulates difference in brightness between two with the unresolvable color of eyes by filtering apparatus, obtains distinguishable information mode.The present invention is the unresolvable color of eyes, by certain frequency and duty ratio modulation in brightness with maybe can differentiate color.
The information mode that can differentiate has multiple, and the filtering apparatus that for example utilizes eyes to wear to have different optical filtering performances makes two corresponding filtering apparatus of difference, and makes two in the transmitance ratios of desiring between resolved spectroscopy significant difference to be arranged.Promptly be with the unresolvable color of eyes,, be modulated on the difference in brightness between two by filtering apparatus.Again for example with the unresolvable color of eyes, be modulated in the flicker by the brightness of certain frequency and dutycycle and the color that maybe can differentiate.Can pass through liquid crystal light valve, or gamma camera and computer realization.
Below we illustrate the principle of achromatopsia-correcting glasses of the present invention, because it can make the patient can not distinguish the brightness of certain color object, the brightness of color object becomes a little less than the last one one in two of users, this strong one weak ratio is exactly the projection on this one dimension that increases newly, then increased new one dimension on patient's colour vision vector space, this colour brightness is exactly the projection on the one dimension that increases newly at the ratio between two.This has in theory just solved the problem of monochromatic blind (as anerythrochloropsia) at all.And can also be used to realizing strengthening the color discrimination of normal eye zang.Certainly for achromatopsia, set up the colour vision psychic reflex, also should blinder than monochrome at least situation difficulty, wear the color that can not discern before this mirror but still can discern.For the blind situation of monochrome, setting up new colour vision psychic reflex should be to be relatively easy to.This be because, at first, the disposal ability between two is extremely strong, how much parallaxes are widely used in third dimension, and the brightness parallax formally do not taken again, the existing colour vision of patient is experienced very firm; Take second place, brightness is most important, the most direct, the most responsive physical quantitys of eyes, and the reflection relevant with luminance difference should be set up easily; At last, it also is a very interesting relevant experience, situation about occurring once in a while when our brightness parallax, as when the old-fashioned black and white stereo of watching that two frames are combined into, by chance appearance is wherein made a mess of at one something place, has changed under the situation of brightness, will occur a kind of unusual, inharmonic impression on the object that the brightness parallax occurs, this impression just can be experienced by the colour vision of " definition " Cheng Xin, is that " accurate colour vision " experienced at least.And can also be used to realizing strengthening (special type) color discrimination of normal eye.Wear the optical filtering eye plate of different optical filtering performances separately when eyes, these two have different optical filtering performance devices, in the transmitance ratio that requires between the spectrum of being differentiated, tangible difference is arranged, and these are through spectrographic relative intensity at least in that to arrive eye unlikely when too weak, and these can not just can have been differentiated by the spectrum that normal eye is differentiated.Behind first use achromatopsia-correcting glasses of the present invention, just can produce corresponding color identifying power as long as adapt to a little or train, set up new colour vision and experience, or " accurate colour vision " experience.
Other purpose of the present invention, effect and advantage, will be partly in following explanation:
(1), the present invention can make the information mode that undistinguishable certain color modulation of achromate becomes can differentiate.For example certain color becomes a little less than the last one one in two of users, has so just increased new one dimension on patient's colour vision vector space.The two ratio is exactly the unidimensional projection that increases newly.Solved monochromatic blind (as anerythrochloropsia) colour vision dimension of a vector space and be two problem.Solved the problem that other achromatopsia antidote can not solve in itself.
(2), the present invention can also be used to realizing strengthening the color discrimination of normal eye.
(3), that the preferred embodiments of the present invention are corrected the achromatopsia effect is obvious, simple in structure, easy to use, can also use as common spectacles.
(4), the characteristic of this enhancing color discrimination of the present invention can also be used for other occasion effectively.
The invention provides and a kind ofly can make the achromate really increase chromatic discrimination power, can see colors such as achromatopsia checking figure table, traffic lights clearly, but also can directly produce for " lose color " concrete achromatopsia-correcting glasses of experiencing and strengthen the method for color discrimination.
