THE COLOR VISION colorblind
They see more or less gray, but not true color , not particularly distinguish red and green.
As with optical coatings that do not heal as refractive errors , why not think
to treatment of congenital dyschromatopties ? Palliative treatment designed to help
. not a cure . It was long abandoned it , citing security reasons. these
are still valid and it is not to circumvent , especially for certain businesses:
train drivers , airline pilots etc. … Access to these professions is governed by binding tests where color vision is paramount and there is no question in this test waived. But apart from these trades , there are many who suffer dyschromates following the vagaries of their daily infirmity. Dyschromatoptie that is known or misunderstood the subject, the consequences are social and professional.
In an attempt to treatment , a method has been outlined. Twenty children in dyschromates
benefited . We report the results.

Obviously a treatment which does not claim to cure, but which attempts to reconcile the patient with life daily , hence the name of each color requires us normal behavior.
It may be light traffic , colors of electrical components and son , different
mistakes when they are wrong color , etc. ….

Clinical observations:
It allowed us to review and monitor a Parisian artist , colorblind out, and painted in a way
remarkable poppies. Green and red flower are very well reproduced .
We wondered how he has you have done it ?
The answer is simple: through exercise. Working day colors it happens to reproduce
fidelity the true colors of nature.
Why not be inspired to promote a method of treating abnormal vision
colors? That’s what we tried to do with motivated children.

Treatment trials:

At the request of parents treatment was subjected to color-blind children. Their blindness is proved by review boards to Ishihara ‘s .

Hardware Requirements:
1 – planks recalling the basic colors and the result of their combinations .
The patient is asked to reproduce these mixtures on blank rectangles.
2 – boards made ​​of white rectangles, arranged in horizontal columns. Only the first rectangle is colored , the color serves as a model , the young patient is asked to color the rest of the white rectangles depending on model.
First candidate treatment is initiated learning basic colors and results mixtures thereof.

 

The mixture of yellow and red gives orange .

Le mélange du jaune et du rouge donne de l'orange.

 

The mixture of blue and red gives purple.

Le mélange du bleu et du rouge donne du violet.

 

The mixture of blue and yellow gives green.

Le mélange du bleu et du jaune donne du vert.

A researcher discovers glasses canceling the effects of color blindness
A researcher discovers glasses canceling the effects of color blindness

Unwittingly , a British researcher found glasses could help many colorblind better perceive colors in their daily lives . Originally developed for medical use , this optical equipment violet color , called Oxy- Iso , helps caregivers to better perceive the patient’s vasculature and possible bruising. These glasses , developed by American Mark Changizi , intensify the contrast between skin color and those blood vessels. Using them for the first time , Dr. Bor , University of Sussex ( UK ) , colorblind his state , found a dramatic improvement in his vision. He said he was ” driven by a frisson of excitement ” seeing things ” hitherto invisible” to him.

Indeed , glasses Oxy- Iso , distributed by the company 02AMP , filter the rays that interfere with the ability to distinguish different shades of red and green. Unrelated to their original purpose , they will compensate for the consequences of deuteranopia , the most common form of color blindness. The revelation of Dr. Bor has been corroborated by numerous testimonies of colorblind who also found the same effects on their vision. It is not however a panacea , because these glasses impair vision yellow and blue … The price of 250 euros, can be daunting . This equipment , however, can be an effective aid in some difficult situations for colorblind … like stage dressing in the morning! Recall that this vision disorder affects 8% of the male population and 0.5 % of the female population.
