1. Peripheral vision

When you are tired your peripheral vision shrinks.


This is what allows you to see things around you without turning your head or moving your eyes. It helps you to feel the movement and move without crashing things. That’s what you use to see something “in the corner of your eye”.

Yes, it can shrink, due to eye lids sagging a little bit with sleep deprivation or many other reasons.
