What is the Ishihara Test?

A color vision test using colored circles.

How is color blindness detected?

By identifying numbers in colored circles.

Color Count, Munker Illusion, Animal Instincts, and more.

Based on performance in all tasks, with a maximum of 23 points.

To detect color vision deficiencies and assess perception.

The Ishihara Test for color Deficiency assesses color vision by having participants identify numbers in colored circles, with errors indicating color vision defects.
The test includes various tasks like Color Count, Animal Instincts, and Word Games, each challenging different aspects of vision and perception, culminating in a final score out of 23 points, with most participants scoring between 10-20 points.

The Ishihara Test for color Deficiency is used to detect color vision handicaps.
Participants are asked to identify numbers within colored circles to determine color blindness.
Correct identification of numbers indicates normal vision, while errors suggest color vision defects.
A series of eight tasks with varying difficulty levels are presented to test visual acuity.
Participants must answer all questions correctly in each stage to earn a point.
The Color Count task involves identifying a different color among 10 options within a time limit.
The Munker Illusion is used to test perception by hiding odd-colored balls among others.
Animal Instincts task requires identifying hidden animals in images within a time limit.
Crunching the Numbers task involves finding hidden numbers within images under time constraints.
Word Games task involves finding hidden words within pictures within a time limit.

In a visual challenge, the participant is required to identify multiple words in each picture within a set time frame, adding two seconds to the timer for fairness.
The participant progresses to a task involving the Ponzo Illusion, where they must determine if yellow lines are of different lengths or the same.
A strawberry test challenges the participant to identify the color of strawberries in images, which are actually gray due to color perception illusions.
The final task involves identifying hidden words and pictures behind bars within a time limit, with points awarded for correct answers.
The participant's final score is determined based on their performance in all tasks, with a total of 23 points possible.
Scoring between 0-10 points is common, with 20% of participants falling in this range, while 40% score between 10-15 points and another 40% score between 15-20 points.
Achieving a score of 20-23 points is rare, with no participants reaching this level before the test was released online.
