Directions

This activity will show you how different types of color blindness impact an image. Select a type of color blindness from the right, review how the image changes, and select the eye icon under the image to learn more about that type of color blindness. Select Begin to start with Trichromacy or full color vision.

Trichromacy

Trichromacy or trichomatism is the ability to perceive a full range of colors. Someone who does not have any form of color blindness has trichomatism.

Deuteranomaly

Deutranomaly is a form of red-green color blindness that is caused by a defect in the M-cones. People with this condition have difficulty distinguishing between shades of red and green, and they may also see colors as less vibrant. This is the most common type of red-green color blindness.

Deuteranopia

Deuteranopia is a form of red-green color blindness. This color blindness is caused by a defect in the M-cones. People with deuteranopia have a limited range of colors, primarily shades of yellow, blue, and brown.

Protanomaly

Protanomaly is a form of red-green colorblindness that is characterized by a reduced sensitivity to red light. This is caused by a defect in the L-cones. People with protanomaly have a difficult time distinguishing between shades of red and green; colors may also be perceived as less vibrant.

Achromatopsia

Achromatopsia is a monochromacy. It is a rare condition that is caused by a lack of functioning cone cells in the retina. People with achromatopsia only see shades of gray, black, and white. They may have reduced visual acuity (sharpness of vision), be extremely sensitive to light, and/or experience nystagmus (involuntary rapid eye movement).

Protanopia

Protanopia is a form of red-green colorblindness that is characterized by an absence of functioning L-cones. People with protanopia are completely unable to distinguish between red and green. Colors may appear less vibrant when compared to those with trichromacy.

Achromatomaly

Achromatomaly is a blue cone monochromacy. This genetic mutation is involved in the development and function of cone cells in the retina. People with achromatomaly generally see the world in shades of grey with limited colors. They may have difficulty with depth perception and poor night vision.

Tritanopia

Tritanopia is characterized by the complete absence of functioning S-cones. People with tritanopia cannot see blue. They are completely unable to distinguish between blue and yellow. They primarily see the world in a limited range of colors, primarily shades of green, red, and purple.

Tritanomaly

Tritanomaly is a form of blue and yellow color blindness. People with tritanomaly have an abnormal function of the blue cones in the retina. They have difficulty distinguishing between shades of blue and yellow. Beige is also a problematic color for those with tritanomaly.
