Color Blindness Exam

Approximately 1 in 12 men and 1 in 200 women have some degree of color blindness. Among different types of color blindness, the most common is known as ‘red-green color blindness.’ Color blindness (also called color vision deficiency by vision scientists), is a condition in which the retinal cone cells respond to light differently than normal. People with color blindness can usually still see colors but have color confusions or see certain pairs of colors so similarly that they cannot tell them apart. Our app helps adults and kids to test for color blindness in a fast and easy manner. Our color blindness exam is adapted from Dr. Shinobu Ishihara's popular color perception test, which is used worldwide by eye care professionals. ---------------------- As the exam starts, you will be shown a series of test images. Each image may or may not display a number. Each number may contain one or more digits. You will be asked to type the number that you see in the image and tap the "Done" button. If you do not see any number, you may tap the "Pass" button. Good Luck! ---------------------- Disclaimer: This test is not a substitute for a diagnose conducted by an eyecare professional.
