Information and Blindness Test. It includes blades famous ishihara test
Are you Daltonic?
If you install this app in 5 minutes you will know (thanks to the various tests that appear). This application includes 11 Ishihara test sheets (the most popular test and used by ophthalmologists to evaluate the perception of a person's color), 6 sheets of another additional test and an inverse test of daltonism (which shows some images whose number or drawing can only see, in theory, the Daltonic people). Also in the application you will find additional information about daltonism.
This free application is based on the Ishihara color test. He owes his name to his designer, Dr. Shinobu Ishihara, professor at the University of Tokyo, who published the first version of this test in 1917.
The application now also includes a second test, the inverse test of daltonism. It is a test that in theory can only correctly solve people with daltonism and non -daltonic people are unable to solve it.
Important: the realization of these tests of daltonism is merely approximate and does not exclude, in any way, the review by an optical or ophthalmologist.
Both the screen of the device with which you visualize the test and the type of environmental light (natural or artificial) and its intensity and angle of incidence can affect your perception of images altering the result.
