Color blindness is a condition where someone could not see the difference between two colors or more. There are some color blindness classifications, and so there exist some methods to test whether or not someone has color-blind symptom (and if so, in what classification). Ishihara test is a standard and simple world wide-known and used test. Ishihara used 38 pages filled with multicolored dots which some of them resembles numbers or colored-path.
There are two most important disadvantages of using Ishihara test tool. First, the tool (book) is not easy to find (or buy), so anyone who wants to take the test usually go to the doctor or some eye-specialist clinics. Second, the images shown in the book were static. It means we can cheat the test by memorizing each number(s) appeared on every page.
Computer-based test can solve those two problems. The application has been
evaluated and tested in Rumah Sakit Mata Cicendo Bandung. The result shows, that this particular application can classify up to eight color-blind types (protanopia, deuteranopia, weak protanomali, weak deuteranomali, strong protanomali, strong deuteranomali, and both monochromat complete color blindnesses).
