How to test for color blindness?
The first test for color vision deficiency was developed by Japanese ophthalmologist Ishihara Shinobu for military use in 1918. Today, the Ishihara test is still the primary test used to determine if you have red-green or blue-yellow color deficiency. You or your child will be shown a set of Ishihara color plates. For example, to test for red-green color blindness each plate has a red or green number hidden within a set of dots. If you can’t see the figure, you have tested positive for red-green color deficiency. There’s also a set of Ishihara plates with blue or yellow figures hidden within a set of dots. If you can’t see the blue or yellow figure, you’ve tested positive for blue-yellow color blindness.

What do we see when we see different colors?

How do monkeys cure color blindness?
Gene therapy experiments at the University of Washington show promise in curing red-green blindness. Experimental Gene therapy has successfully allowed red-green color-blind monkeys to see new colors that they have never seen before. Scientists used a computerized test for human color blindness similar to well-known test books where colored numbers or symbols are hidden in a pattern of dots. Before treatment, all of the monkeys were trained to touch a colored patch located among the gray dots in the pattern. A Correct choice was rewarded with a small amount of white grape juice and a positive dinging sound. Following an incorrect choice, no juice was delivered, and a negative buzzer tone sounded. Similar to color-blind humans, the monkeys could not distinguish red or green, but following treatment, they passed the test for all colors.
