Question

Why cant we see/ focus on things in our peripheral vision?

In: Biology

Answer 1

We do not have vision cones that cover our peripheral vision. And the vision rods which do cover it are spaced very far apart in that region of our retina. So we can not see color and we can not see clearly. The reason why this seams odd to you is that your brain fills in the missing information with things it remembers. So you do not notice that you are essentially blind in 95% of your vision field. But your vision is good enough to notice movement which makes your eyes move to that spot automatically and update your memory of it.
