4 - Color blindness

The topic that I’m going to talk about is Color blindness. I chose this topic, because I’m a color blind person and I can’t see the world like the way that you see the world and I want you to understand how and why is it happening to a certain people like me. 

Take note; not all of color blind people are not really color blind, but color deficient, which means we get only confused on distinguishing between certain shades of color such as Blue & Violet, Red&Pink, Green&Brown , the term color blindness is misleading. 

So what is Color blindness?

Many of you might think that being color blind means you only see things in black and white,  however there is one very rare type of color blindness that can really only see shades of gray, and It’s called “achromatopsia” or what most people call “monochromy”.   



Color Blindness is almost always inherited and it affects approximately 1 in 12 men  and 1 in 200 women around the world, but there are times when it’s cause by physical damage or chemical damage. I think most of you didn’t exactly know what it is like to be color blind, unless you were born a Color blind person

Actually there are three main types of Color vision deficiency, We have tritanopia(blue cone cells defective),   deuteranopia(green cone cells defective), and lastly we have protanopia or red-green deficiency which is the most common kind of color blindness. 

To clearly understand color blindness, we need to learn a little bit on how our eyes work. 

Our human eyes have retinas that are located at the back of our eyes so we could see and it is consist of rods and cones . Rods help us to have an ability to see at night, while cones allow us to see different kinds of colors in bright environment. Actually there are more rods than cones in our eyes. There are three cones in our retinas, the S-cone, the M-cone, and the L-cone, these cones help us to see colors like blue, red, green, and all the different colors that they make, when these cones are all working properly, normal color vision is the result, however when one of those cones are missing, defective or overlap, then color blindness occurs. From what I have searched up in the internet, Color blindness is a permanent problem, there is no cure, however there are many advanced technology that can help color deficient people see more colors.

So how did a color blind person knew 

that they have this kind of problem?

Actually, I have here some several images/plates and it’s called ishihara test. 

As you can see, there are many colored dots that are connected, and I think there’s a formed number,  I wish I could see what number was formed, but seriously I really can’t see it, but there are .  Usually when we’re taking medical or taking an entrance exam from other college schools, we might encounter this test.

You can also test your color vision from this website:

 to know if you're colorblind or not.

In conclusion, being color blind makes it difficult to put matching outfits together and it may effect our career choice, being color blind is not a big problem, you could still see everything, but you just see it a little differently, It only affects the color what you see and not what you could do.
