Blind people look at things different from ordinary people

People with Blue Cone only look at things under blue, and if they are blue blind you cannot distinguish blue and green with yellow or purple.

According to Medical Daily, while most of us see the world colorful, some people are not. Color blindness makes their surroundings more gloomy but does not mean only black and white. The group of researchers from Compare London Hospital (UK) has created images that compare the difference between normal eyes and colorblind people to help the community better understand visual defect disease.

Blue Cone Monochromacy (blue monochrome)

Blue Cone Monochromacy is a rare genetic disease in the retina, almost exclusively affecting men. The color discrimination of Blue Cone Monochromacy was severely weakened at birth. They look at everything that turns green.

Tritanopia (blue blind)

People with Tritanopia find it difficult to distinguish blue from green or yellow from purple. However, they rarely encounter problems in their daily lives, such as looking at traffic lights. Unlike other color blindness, the incidence of Tritanopia in men and women is the same.

Deuteranopia (green blind)

Deuteranopia is one of the most common types of color blindness. Green cells that are sensitive to lost green color make you distinguish only 2-3 different colors.

Protanopia (red blind)

People with Protanopia are less sensitive to red light. They are difficult to distinguish between blue and red or green and red due to the complete loss of red-sensed cones.

Achromatopsia (complete color blindness)

Achromatopsia is a condition characterized by partial or total loss of color vision. Achromatopsia sufferers see nothing but black and white and some gray tones. In mild cases, patients can distinguish some colors but are very limited.
