COLOUR BLINDNESS TEST BOOK: Ishahara, 65x Images

$ 82.85 excl. GST

This is a good example of a colour perception test for ‘red-green’ colour deficiencies. The test consists of 65x images in a book 210mm long x 145mm high. Each plate contains a circle of dots of random size and colour. Within the circle of dots a number or shape is clearly visible to those with normal colour vision, and invisible, or difficult to see by those with a red-green defect.
