ELi5: How come when there’s something in your field of vision, your eyes can basically “see through” the object when you’re looking past it?
In: Biology
The images your brain gets from your eyes get merged together into one image that you “see.” Since there’s a lot of overlap between the two inputs, objects that don’t match what your brain expects or that are deemed irrelevant (like your nose) are just ignored/erased if there’s enough data to do so, and merged into a composite if there isn’t.
