I decided to document my favorite day of the week - Friday. As friday is the secret day for jewish people I usually go to dinner with family or friends. I decided to use pictures and capture with my phone a few hours from that day. As part of assistive technology class I've been learning about web mobility and I wanted to do this homework and see my images through the eyes of a color blind person. Color blindness, or Color Vision Deficiency (CVD), affects roughly one in twelve men, and one in two hundred women. That's over 8% of the population.
I mostly thought that color blind people would see the world in two colors - black and white but I realize that colorblind doesn't work like this and people with this disability see different ranges of colors. To understand better how colorblind works I wanted to understand the range in the colors and what they see.
Protanopia - The least common color blindness. 1% of men suffer from it. Blindness to red is due to a complete lack of red color receptors in the retina and sufferers of this type of blindness see red as black and have difficulty distinguishing shades of green:
The hour in my eyes:
Deuteranomaly - is the most common among color blindness and is due to a defect in the green color receptors in the retina. This type of color blindness is especially common among men: almost 5% of them suffer from this blindness and some are not even aware of it. Deuteranomaly impairs the ability to distinguish between red and green and causes colors to lose their brightness:
The hour in my eyes:
Tritanomaly - Is due to a similar defect in the blue color receptors in the retina and is extremely rare. Tritanomaly impairs the distinction between blue and orange:
The hour in my eyes:
Monochromacy - Color blindness characterized by the inability to distinguish colors. This type of color blindness results from a congenital defect that causes a deficiency of suppressed cells or impair their function:
The hour in my eyes:
Triranopia - A very rare defect that affects a very small percentage of men and women and is due to a complete lack of blue color receptors. Those who look at it see the world in shades of pink-green:
