I don’t have an answer for this, but I will tell you WHY I don’t.

Because on that day of my college lecture where they explained the anatomy of the eye and how our brains perceive vision, I accidentally went to my 8 am class high on mushrooms.

So here’s the ELIHOMAWMITLTISB(Explain Like Im High On Mushrooms, And Way More Into The Lecture Than I Should Be):

They’re like little cameras in our skulls, that repeatedly focus over and over again, like a video, and our brain perceives each frame in real time, then plays the movie back to us immediately.

And SOMETIMES, the image ISNT in focus. So we wear glasses to put the image in focus, and then our eyes adjust again on top of that. Like attaching different lenses to the camera! We’re all just walking, talking video cameras, able to instantly understand and THEN write imdb reviews about what is being filmed, while we’re filming it!

Crazy right?!

Anyways, I got a C.
