This test is used to check your eyes' ability to see colour. (The most common form of this test is called an "Ishihara Test" after its designer). In the test you will see circles made up of dots of different colours and shades. Within these dots, you may or may see numbers or odd patterns appear in different colours. You will be asked to identify whether you can see any numbers of patters in the dots.
