The way our eyes process the world around us is often taken for granted. And it’s quite unusual considering that we primarily rely on eyesight to navigate our daily lives. What we see as “white” light is actually an amalgamation of different colors fused into what our brain interprets as white light.
A simple prism is enough to demonstrate this phenomenon. Simply allow sunlight to strike the prism and you will see the light refract into different colors. It’s the same principle behind seeing a rainbow in the sky.
But within this realm of color, there are people who are unable to “see” the colors for what they are. This is termed as color blindness or color deficiency. Roughly speaking, around 8% of men and about 0.5% of women around the world are color blind to some extent. And yes, there are several types of color-blindness and are commonly caused by genetics.
The National Eye Institute divides color blindness into three general categories. The first is red-green color blindness which is also the most common. These are the people who confuse the red and green colors and can have difficulty interpreting traffic signals. Next is blue-yellow color blindness and it occurs when one is missing Tritan (blue-cone) photopigments or if their function is impaired. Monochromacy, or complete color blindness, is self-explanatory. They can’t distinguish any color at all and the sharpness of their vision is also affected.
Within these categories are several other sub-categories but we don’t need to get into them here. The important thing to note is that there are several types of color blindness and some people don’t even realize that they have a form of color vision deficiency! It’s not necessarily bad because you can still be completely functional. It’s just that the way you experience colors will be different from other people.
There are, of course, tests to determine one’s level of color blindness. The most commonly used tests are the Ishihara Color Test and the Cambridge Color Test. But the following is one easy and fun test that will let you know if you’re one of the people who have color vision deficiency of some sort.
The test is comprised of eight different color tiles with a hidden word printed on it. A person with perfect color vision will be able to read all eight words.
Are you ready? Scroll ahead and find out how perfect your color vision is and take note which color you have trouble with if you don’t!
1. The hidden word is TREE. Did you see it?
2. A lot of people enjoy this activity: EAT.
3. This is what you should wear when you go hiking: BOOT.
4. This is where kids like to play: PARK.
5. The reason we’re getting fat: SWEET!
6. How’s the score so far? The next word is something we all need: LOVE.
7. A must if you’re going out on a sunny day: HAT.
8. And finally, BEAD. So, were you able to ace the test? If not, what colors did you have trouble with?
