There have been a lot of different tests for color blindness developed over the years, and the good news is that you can find many of these tests and charts online. There are a few things that you should know about taking any color blindness tests online though.

No matter how convincing some of them may seem the only way to know for sure whether or not you have some sort of color vision deficiency is to talk to your eye doctor about it. Some color resolutions on computer monitors can give false positives or false negatives, no matter how professional looking they may seem.

One of the most famous tests for color blindness is known as the Ishihara test.

There's a good chance that you have been exposed to this test at some point in your life, since I believe most children are given a Color Blindness exam these days, but depending on how thorough the exam was you may not have gotten complete results. The way the Ishihara test is set up, it allows the Eye Care Professional or Eye Care Specialist to easily distinguish not only whether or not you are color blind, but also what type of Color Blindness you have. There are 38 levels to the Ishihara Color Blindness Test , but not all doctors go all the way with them.

The test is arranged in a series of plates, each of which has different colors printed on it in the form of closely packed together dots. Most of the plate will consist of one color, at least in the early levels, but there will be a number right in the middle that is made out of dots of a different color.

The way the test is graded is extremely easy: if you don't see the number, you have some sort of color vision deficiency. The different plates will use different combinations of colors, which will allow your doctor to pinpoint exactly what type of deficiency you have. The most common form of Color Blindness is known as Red Green Color Blindness .

In this form, the person would not be able to distinguish between the color red and the color green. To them, both of these colors would be the exact same shade. Therefore, if the background of the Ishihara plate is green and the number inside is red, they wouldn't be able to see the number. It would just look like a whole bunch of dots to them.

As the plates progress, they also progress in complexity. For example, while the first level may be only red and green, one of the more complex plates may use red, yellow, and blue in the background, and then the number would be formed out of green. This allows the eye doctor to get a fix on any issues even if they're extremely slight.

Some Types of Color Blindness are so slight that in normal everyday life you wouldn't even notice them at all. There's no reason a person with Vision Color Blindness can't live a normal life.
