GENERAL CHARACTERISTICS -

Pediatric Ishihara test with simple drawings easy to identify by children.
10 board series designed to provide a quick and deep test in determining the congenital deficit vision of color, the most common form of discomfort of the color vision.
The examination of the chromatic sense takes place through discrimination of different background colors and signs10a.
Ishihara tables are used for the diagnosis of discromatopsia, optical neuropathies and congenital or acquired maculopathies.
10th: the different colors are placed in the same line of confusion.
They signal:
• Protanopia (red): the visible range of the red spectrum is shorter than normal and that part of the spectrum that normally appears blue-green, appears gray to who has protanopia.
• Deuteranopia (green): the part of the spectrum that seems green to those who have a normal vision appears gray and the visible spectrum range is divided by this area into two areas, each of which seems different.
The visible spectrum range is not contracted, in contrast to protanopia. The red-purple, complementary color of green, also looks grey.

In the acquired forms of impairment of the vision of colors, protanopia and deuteranopia are indicative of the optical neupotia.
