Empowering Your Color Blind Testing Success: Practical Hacks and Tips to Excel!
Gone are the days when you had to visit the doctor’s clinic for a color blindness test. Thanks to the internet, you can now take online color vision test from the comfort of your own home.
However, it’s crucial to remember that any positive result for color vision deficiency must be confirmed by a professional using other test for color blindness, such as the Ishihara color plate or anomalscopy.
Did you know that color blindness is often inherited? If someone in your immediate family has color vision deficiency, you may be more likely to develop it as well. The human eye contains unique cells called rods and cones that work together to allow us to see.
Cones, in particular, are responsible for color perception, with three types – red, green, and blue – allowing us to distinguish between different hues.
When cones are not functioning properly, color vision deficiency occurs. This can manifest in several ways, including red-green color blindness, which is the most common type resulting from abnormalities in red or green cones. Another types include blue-yellow color blindness and total color blindness.
While there’s no cure for color blindness, special lenses can help alleviate symptoms and enable you to live a normal life.
So, if you or someone you know is experiencing any color vision difficulties, don’t hesitate to consult with an eye care professional for further guidance.
What is a Color Blind Test?
When you think it likely that you have color blindness because of a family history or have difficulty recognizing some colors, your doctor will perform a color vision test to confirm the diagnosis. A color blind test involves reading special characters formed by multi-colored dots on specific backgrounds.
People with color vision deficiency often struggle to see letters or numbers formed by these dots. If you have total color blindness, you might not see anything in the test charts and plates.
Screening Tests for Color Blindness
Color blindness can be detected by various methods, including color plate, hue, and anomaloscope tests.
Color Plate Test
There are multiple types of pseudoisochromatic color plate test, with Ishihara charts being the most typical variant. The color plate tests require you to identify letters, shapes, or numbers made of dots featuring a specific color on a multi-colored background. If you have an abnormality of the cones, you might not identify the pattern at the center of the plate.
Besides the Ishihara test, color plate variants include Dvorine, American Optical Hardy-Rand-Rittler, Tokyo Medical College, and City University Test. These screens check for different types of color blindness. For example, the Ishihara test checks for only red-green blindness while the Hardy-Rand-Rittler can identify blue-yellow and red-green color vision problems.
Arrangement Tests
Also known as hue tests, the arrangement test requires you to arrange blocks of different colors in a particular order. The design of the tests makes them suitable for evaluating various aspects of color vision, including fine hue discrimination, neutral zones, saturation discrimination, and color confusion.
If your work requires excellent color vision, arrangement tests are the best option for screening and diagnosing color deficiency.
While these tests are more objective, they are not suitable for the pediatric population, as they require patience, abstract ordering, and dexterity.
Anomaloscope test
Anomaloscope is an optical instrument with two different colored fields and control knobs. Your doctor will ask you to look into the anomaloscope and match lights in the two fields to have the same color and brightness. You will use the knobs to manipulate the colors.
Anomaloscope is the standard test for diagnosing color blindness. When performed together with other tests, your doctor can accurately use the assessment to categorize your color vision deficiency.
Online Color Blindness Tests
Online vision tests offer a quick self-assessment for color vision. Most online tests are a replica of the traditional pseudoisochromatic plate tests like Ishihara, with reliable outcomes in most cases. Notably, factors such as blue light filters and the type of device can affect the outcome of online color vision tests.
Taking a Color Blind Test is More Than Just Checking Your Vision
Color blindness is primarily an inherited vision disorder with a male preponderance. Every one in ten males has a color deficiency, while only one in two hundred females will have the condition.
Therefore, males, especially of Northern European descent, should take color blindness tests early. If color deficiency runs in your family, screening for the disorder early enough, regardless of gender, is essential.
Acquired color vision deficiency can occur in individuals with any of the following local and systemic conditions:
1. Diabetes
3. Parkinsonism
4. Leukemia
5. Glaucoma
Alcoholism and some drugs like hydroxychloroquine also increase the risk of developing color blindness. Screening for color vision deficiency is vital if you have any of the mentioned conditions.
Right Age to Test for Color Blindness
Since most color blindness is mainly an inherited vision disorder, testing should begin early. Research shows that taking your child for color deficiency screening at age four, followed by appropriate treatment, is essential for optimal school performance.
FAQs
How do you test if you are colorblind?
You can screen for color blindness using online tests such as Enchroma, but you need to see an ophthalmologist or optometrist if the screening test is positive.
What is the most accurate color blind test?
An anomaloscope test is very accurate in diagnosing color blindness, but you may need to supplement its results with information from other tests to categorize the disorder accurately.
Can I correct my color blindness?
Many people are looking for a correction of their color blindness. But unfortunately, there isn’t any real correction possible. Out blindness test can only help you to know the level and type of your blindness.

Is there a reason that color blindness is essential to diagnose? Why?
First of all, I don’t think it should be tested in general. Only if you have some concerns, a test can help you very much to classify them. It is important to diagnose color blindness because only then can you take proper precautions to help, for example, your child with homework.
