Did you know that approximately 5% of the world population have trouble seeing some kind of color, many of whom do not even know it?
The fact is that, both for those who suffer from this anomaly as for “normal” people understand this disease is extremely difficult – after all, it is difficult to imagine the world with both a color with shades less as you do not even know exist.
But colous Blindness Simulator comes with the aim of increasing understanding of both sides. For this, it allows people to see the world as someone with this disability: you simply upload an image to the service (this should take no more than 100 KB in size and resolution 1000×1000 pixels), choose the type of visual impairment and click “Simulate Colour Blindness”.
By doing this, the website shows a comparison with thumbnail images of the normal photo and the photo without the colors that normally would miss someone with proper disability. If you are unable to perceive differences between one image and another, felt inform: you own blindness.
Understanding color blindness
As stated just above, one of the steps to use colous Blindness Simulator consists in choosing their type of disability. This is because color blindness is divided into three different conditions; each representing the inability to see a spectrum of color.
Below is a brief description of each:
- Protanopia: People with this condition have no retinal cones of the long wavelength. They are unable to distinguish the colors of green, red and yellow section of the spectrum;
- Deuteranopia: People with this condition have no retinal cones of the mean wavelength. As in Protanopia, they are unable to distinguish colors of green, red and yellow section of the spectrum;
- Tritanopia: the rarest of the three anomalies have retinal cones short wave length inactive. Therefore, they do not see blue and yellow, plus “mix” both.
- Now that you know how each one works, will certainly be easier to identify the differences caused by them in the pictures altered by the simulator.
Colors Blindness Simulator is another case of a great proposal with an implementation that leaves much to be desired. For starters, its interface is amateurish (it looks like a simple blog) and crams too much information, as to hinder the reading of information – and, in turn, preparations to use the simulator.
Even if you go through this and be able to activate the program, prepare yourself for a sobering comparison: as you can see on one of the images from the description, the service brings only a couple of tiny images, so small that, in fact, many will have trouble identifying the differences on the screen.
