The Ishihara Color Test was named after its designer, Dr. Shinobu Ishihara, a professor at the University of Tokyo.
The test consists of a number of colored plates, called Ishihara plates, each of which contains a circle of dots appearing randomized in color and size. Within the pattern are dots which form a number or shape clearly visible to those with normal color vision, and invisible, or difficult to see, to those with a red-green color vision defect, or the other way around. The full test consists of 38 plates, but the existence of a deficiency is usually clear after a few plates. There is also the smaller test consisting only 24 plates. This app is an 24-plates test.
The plates make up several different test designs:
- Transformation plates: individuals with color vision defect should see a different figure from individuals with normal color vision.
1) Vanishing plates: only individuals with normal color vision could recognize the figure.
2) Hidden digit plates: only individuals with color vision defect could recognize the figure.
3) Diagnostic plates: intended to determine the type of color vision defect (protanopia or deuteranopia) and the severity of it.
The application has 12 types of eye tests:
* Visual acuity tests (based on a Snellen chart, numbers and text, with black or white background)
* An Ishihara Color Blindness test
* 4 Amsler grid tests
* An AMD test for macular degeneration
* A Glaucoma survey
* A Written test aka. how much do you know about the eye?
* An OKN Strip test
* Red Desaturation test
* Contrast Sensitivity test
* Duochrome test
* Landolt C/Tumbling E test
* Astigmatism test
Due to variations in each screen accuracy (screen size, brightness/contrast, resolution) the eye tests are not perfect. Holding a phone of approx 4" screen size 30 cm/12 inches from your eyes would give you nearly accurate results. Hold it (place it) 52cm/20inches from your eyes if you have e.g. a 7" tablet.
Do not consider the tests in the app official tests. These tests only mean to give you an idea whether or not you should see an eye doctor or go on an eye therapy.
The visual acuity test is a routine part of an eye examination, particularly in case of vision problems.
Color Blindness is a commonly misleading term, because most people think color blind people cannot see colors. They can see colors, but cannot make out the difference between some couples of complementary colors.
The Amsler grid is a grid of horizontal and vertical lines used to check vision problems caused by changes in the retina, particularly the macula as well as the optic nerve.
Age-related macular degeneration is a progressing eye condition that affects millions of people. The disease attacks the macula, which is responsible for the sharp, central vision.
Glaucoma is a group of diseases that damage the eye’s optic nerve and can result in vision loss. If left untreated, It can lead to blindness. With the proper treatment you can protect your eyes and vision.
The optic nerve is sensitive to red, so when it is damaged, red-colored objects may appear dull, washed-out or faded.
A contrast sensitivity test checks for the ability to differentiate between light and dark.
This test is used to estimate whether you are long or short sighted.
The Landolt C is the standard optotype for acuity measurement in most European countries.
This test is the standard visual acuity test for people who cannot read the Roman alphabet.
Astigmatism is a vision condition that causes blurred vision making it difficult to see fine details, either close up or from a distance.
What to do if I get bad results?
If your results indicate you may have vision problems, you should see an eye doctor. Having regular eye examinations promotes eye health. It also allows your doctor to measure your vision and make the necessary changes to your prescriptions.
You can also download eye training apps to preserve your eye sight and improve vision. You should take better care of your eyes and vision. Preserving vision health is one of our most important thing to do. Omitting eye care and eye exams can result in serious vision damage.
If you experience any eye problems using the web browser, to-do apps, calendars, writing messages or checking the phone book or the call log, you should take this test to check if you need eye treatment and/or vision training.
This test was created by the EnChroma team to assist in the correct recommendation of color enhancing eyewear products.

About our eye:
Eyes are organs that detect light and convert it into electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals.
Visual acuity, or resolving power, is "the ability to distinguish fine detail" and is the property of cone cells. It is often measured in cycles per degree (CPD), which measures an angular resolution, or how much an eye can differentiate one object from another in terms of visual angles.
Color vision is the faculty of the organism to distinguish lights of different spectral qualities. All organisms are restricted to a small range of electromagnetic spectrum; this varies from creature to creature, but is mainly between wavelengths of 400 and 700 nm.
An eye handbook might help you for more info about the eye (or eye tracking).
Pro version is like an eye magic app with 8 new trainings including dominant eye recognition and an eye color blindness test! An eye quiz with exciting eye illusions will be added later!
With Color Blind Check you get a new kind of color vision deficiency test right in your hands. The test itself is simple and easy: just find the differently colored spots which start to show up and touch them. That's all.
This color blindness test can be installed and used right away. As it is easy to understand, simple to use and you don't need to recognize any numbers, letters or forms, Color Blind Check can be done by young children as well. It is even fun to play!

With Color Blind Check you get a tool at hand to share with everyone insights about your color vision or possible color blindness. People can watch you while you're taking the test and see instantly what it means to be colorblind. They start to wonder, why you don't see the differently colored spots appearing and maybe even want to give you hand!
How CBC works
Color Blind Check is based on the scientific knowledge about colors which can be seen and which not by the people who are suffering from the different types of color blindness. To get more precise results, the test is based on four different main colors and as even colorblind people are quite good in spotting brightness differences, Color Blind Check is shifting brightness constantly.
Compared to other well known tests with Color Blind Check it is NOT possible to learn something by heart and get better while retesting.
What CBC measures
CBC Score: An overall score of the test; easy to compare with others.
Duration: Elapsed time for taking the test.
Severity: A severity score between 0 (not colorblind) and 100 (strong color vision deficiency).
PDT Score (Type): A specific score (protan-deutan-tritan) showing the type.
Check Statistics: Detailed performance statistics of the check.
Color Blind Check Features
• Testing color vision deficiency in two to four minutes.
• Quick CBC for testing color blindness in 30 to 60 seconds.
• Simple to handle, no special instructions needed.
• Pause, restart whenever needed during testing.
• Cancel/stop during running test.
• Measuring type and severity of color vision deficiency.
• Statistics of how many tests have been taken.
• Direct link to most recent Color Blind Check result.
• Direct link to highest Color Blind Check score.
• Left-hand mode for easy testing.
• Testing in portrait or landscape mode possible.
