We often take our eyes for granted. It’s unimaginable for us to imagine having impaired version. We all can recognize blind people in our society, as they often have a walking stick or dog to assist them in public. However, there are also the unrecognizable, color-blind people (aka me) that walk among us.
Just a very brief overview of the eye: there are three kinds of cones that perceive different wavelengths: S cones, M cones, and L cones, for short, medium, and long wavelength; but they are also often referred to as blue cones, green cones, and red cones, respectively.
Deutan color vision deficiencies are by far the most common forms of color blindness. This subtype of red-green color blindness is found in about 6% of the male population, mostly in its mild form deuteranomaly.
Deuteranomaly (green-weak) - what I have. This can be everything between almost normal color vision and deuteranopia. The green sensitive cones are not missing in this case, but the peak of sensitivity is moved towards the red sensitive cones.
So what does this mean exactly? Well, for one, I can’t see the below numbers...
Here's another example...this is an original pic:
And here's what it looks like to people like me:
Of course, these pictures look pretty much the same to me.
How did I end up with this? The gene is an X-linked chromosome, which means it was passed down from my mom, and only sons can be affected (or unaffected), while daughters can only be carriers (or unaffected). My mom is indeed a carrier; I'm the only one in my direct family who has this condition!
So please, don't be that guy...
It's a lot more complicated than that!
