But only 1 out of every 200 female children are born with color blindness. About 1 out of every 12 male children have a form of color blindness. So, not surprisingly, color blindness runs in families. If a child is born with color blindness, that means they inherited the condition. People can be born with color blindness or develop it over time. How common is color blindness in children?Ĭolor blindness happens more often than you might think. This type of color blindness is very uncommon. People may also have other vision issues like low vision, amblyopia, and nystagmus. Colors may also look less bright to people with this type of color vision deficiency.Ĭomplete: People with complete color blindness, or achromatopsia, can’t see colors at all. In some forms of blue-yellow color blindness, people have trouble telling the difference between purples and reds. Red-green color blindness is the most common type of color vision deficiency.īlue-yellow: People with blue-yellow color blindness have trouble telling the difference between blue and green and between yellow and red.

There are three main types of color vision deficiency (color blindness): If your error score is more than 4, than you may have color vision deficiency.What are the common types of color blindness in children? Error points from 1 to 4 are almost normal results, with 1-2 small errors. The lower the score, the better the result. The diagram shows the regions of the color spectrum where color discrimination is low.

On mobile, the test is not optimal, please use on PC or tablet for testing. This is the online version of the Farnsworth Munsell 100 Hue test, limited to 40 colors. Online Farnsworth Munsell 100 Hue Test color blind test The first retest may show improvement, but further retests do not significantly affect the score. Low (Weak) Score: About 16% of the population make total error scores of more than 100. This is a normal range of competence for color discrimination. This is a superior range of competence for color discrimination.Īverage (Normal) Score: About 68% of the population score between 16 and 100 on first tests. Superior (Good) Score: About 16% of the population make 0 to 4 transpositions on the first test, or total error scores of zero to 16.

The physical derivative of the test is given on a black background to isolate and accentuate color hues, which are round and roughly an inch in diameter.Įvaluation of the test - About the Scores The rows cover orange/magenta hues, yellow/green hues, blue/purple and purple/magenta hues, in that order. The tiles are arranged in four rows based on color hue. Failures within the observers visual system can be measured as a function of two factors contained within the test either the amount of instances that a tile is misplaced, or the severity of a tile displacement (i.e., the distance between where a tile should have been placed and where it was actually placed.) The final arrangement of the hue tiles represents the aptitude of the visual system in discerning differences in color hue.

Each hue tile between the anchors can be adjusted as the observer sees fit.

Each color hue at the polar end of a row is fixed in position, to serve as an anchor. The most common form of the Farnsworth–Munsell 100 Hue Color Vision Test contains four distinct rows of similar color hues, each containing 25 distinct variations of each hue. There are several variations of the test, one featuring 100 color hues and one featuring 15 color hues.
