The World’s #1 Online Color Blind Test Just Got Better
EnChroma has taken color blind testing to the next level. Unlike old and outdated Ishihara tests developed back in 1917, our new color blind test uses the science of cone isolation to test the sensitivity of each of your eye’s three color-sensing cones and scores them to show you how close or far you are from having normal color vision. And, unlike any other color blind tests on the internet, our new color blind test can be taken while wearing EnChroma color blind glasses so you can compare your before and after results to see the improvement in your color vision deficiency.
I scored 0% on one of my cones, but I can usually see that color. Did I get the wrong result?
Scoring 0% means you did not answer correctly on any of the test images targeting that cone. It does not mean that you can’t see that color at all; rather, it just means that you have a strong defect in that cone.
Why do I get different results on different devices?
Some score variability is to be expected, but if you get very different results on different devices, check if you have any color filtering effects turned on, such as blue-light filtering or color blindness assistive apps. These can significantly impact your scores. For the most accurate results, use the newest device you have access to.
Why do I get less than 100% on more than one cone? Do I have more than one defective cone?
Scoring less than 100% on more than one cone does not mean that you have more than one defective cone. Your defective cone is the one that you score lowest on. Sometimes, people also score below 100% on their non-defective cones. This is related to how the brain processes color by combining the signals from different cones, which in some cases can make it more difficult to see images targeting a non-defective cone as well. Additionally, the blue cone can lose sensitivity as we age, leading to lowered scores.
When I took the old EnChroma Color Blind Test, it told me if my colorblindness was mild, moderate, or severe. Why does the new test not tell me which one I am?
The new test gives much more specific results for each cone, instead of broad categories like mild, moderate, and severe. Your score on your defective cone (red cone if you’re a protan, green cone if you’re a deutan, blue cone if you’re a tritan) is a measure of severity: the lower the score, the more severe your colorblindness.
Is it okay for my non-defective cone score to go down while wearing the glasses?
Sometimes, in addition to seeing increased scores for their defective cone, people see a slight decrease to their non-defective cone scores while wearing the glasses. This is normal and does not indicate that you have the wrong lens for your colorblindness. You won’t notice this effect when wearing the glasses out in the real world.
What can I expect to see if I take the new EnChroma Color Blind Test while wearing EnChroma glasses?
Most color blind people who take the new color blind test while wearing EnChroma glasses see improvements to their defective cone scores.
The Ishihara test, the old EnChroma test, and other online color vision tests were developed only as broad color vision screening assessments and did not use cone-specific colors. Therefore, they cannot show improvement to the individual cones. Only the new EnChroma Color Blind Test can show this improvement.
Why am I still scoring zero on one of my cones when I wear EnChroma glasses while taking the test?
If you score 0% on one of your cones both with and without the glasses, the chances are very high that you are a dichromat. This is a relatively rare form of colorblindness, where one cone type is completely missing. Dichromats generally do not see color enhancement when wearing EnChroma glasses.
What if I take the new EnChroma Color Blind Test while wearing non-EnChroma tinted lenses?
Other products on the market might help on the test, but none use EnChroma’s patented lens technology, instead manipulating relative lightness of colors. EnChroma lenses increase the color contrast in the image, improving your ability to see the cone-isolated hidden symbol. These other lenses may or may not help your test scores but they won’t really help you see true colors.
EnChroma Patented Lens Technology
EnChroma glasses for color blindness are uniquely engineered to give those with color blindness the ability to see more of the broad spectrum of bright color most of us take for granted. Utilizing a patented light filter technique, our lens technology is applied with mathematical precision to address common forms of red-green color blindness.
