Color blindness affects about 1 in 12 men and 1 in 200 women in the world. This series of photos shows what the city of San Francisco looks like through the eyes of people living with the three most common types for color blindness. The visualizations were created by Lenstore as part of a larger project done in collaboration with the organization Colour Blind Awareness. The three forms of color blindness examined are protanopia (the inability to process red light), deuteranopia (the inability to process green light), and tritanopia (the inability to process blue light).
