The two types of color blindness in this category both make it difficult to tell the difference between blue and green and yellow and red. There are two types of blue-yellow color blindness: 2. Tritanopia (aka blue-blind) - Individuals have no blue cones The red-weak (Protanomaly) and Red-blind (Protanopia) colorblind have problems whenever a color has some red in it. A person with protan type color blindness tends to see greens, yellows, oranges, reds, and browns as being more similar shades of color than normal, especially in low light Types of Color Blindness There are three types of color blindness, these are red-green color-blindness, blue-yellow color blindness, and complete color blindness.

  2. What is Color Blindness? Color blindness (also called color vision deficiency or CVD) is a reduced ability to see colors. Someone who is color blind is technically not blind to colors, but may misidentify, confuse, fail to notice or notice colors less quickly than normal
  3. The types of blue-yellow color blindness are: Tritan types have a deficiency in blue cones. Tritanopia means a complete lack of blue cones (dichromacy). Tritanomaly means a shift in the color sensitivity of the blue cones (anomalous trichromacy)

Color blindness is a condition that makes people unable to see different colors. There are a few types of color blindness - protan color blindness, deutan blindness, Tritan color blindness and monochromacy (a complete lack of color sensitivity), which is the rarest kind Below are the four most common types of color vision tests: Ishihara Color Test. Developed by a Japanese ophthalmologist, the Ishihara color test assesses for red-green color blindness. The test consists of 38 plates - each plate has many dots that form a circle on it. The dots are different sizes and hues and form a number, either one or two digits. If you have normal color vision, you should be able to see the number with ease There are two kinds of red - green color blindness: protanopia or deuteranopia. Deuteranopia is the most common form of color blindness; between five and ten percent of males suffer from it. Those affected have trouble telling the difference between red and green.

Protanopia: The person suffers from the absence of the red photoreceptors. Red appears dark in color. Tritanopia: Unlike the above two, this is a rare type in which the person has the red and green cones, but not the blue one. Anomalous Trichromacy. This is the most common of the three types The color blindness is of different types and most of them are inherited and present at birth. Symptoms of color blindness.

Those who have deuteranomaly will typically experience greens, yellows, browns and reds to appear redder or similar.
