As kids, we were all taught that we had 5 senses: sight, sound, touch, taste, and smell. As it turns out, you were lied to. As humans, we actually have quite a few more extraordinary senses that no one told you about, but I’m about to teach you right now. You probably use most of these senses every day, but never realized it.
Blind people can sometimes adapt to their disability to achieve what is known as blindsight. Since the problem doesn’t lie in the eyes, but rather the signalers that travel to the brain, their eyes can still sometimes still see their surroundings and adapt to them. Certain blind people have been known to navigate mazes without issue because of this.
This sense is a gift given to only a small amount of people but it is a more intense sense of sight. While most humans have three cones in their eyes to distinguish shades of colors, tetrachromats have 4 cones in their eyes which gives them the ability to see colors that us normal folks can’t even imagine.
