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.
There are two tests available:
You can check out yoursealf by finding numbers in Ishihara plates or You can find specific patterns in those.
Each plate 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 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.
