[* black] For this simple demonstration, we placed a guitar pick behind the lens, upside-down, to see what the lens saw. As you can see, the upside-down graphic has been flipped right-side up!
[* black] ''Or so it seems…''
[* black] So why is it that the lens flips the image? Wouldn't it be easier of the lens just looked at the image right-side up like we do?
[* black] '''Science Time!''' In actuality, the lens is not flipping the image upside-down, it is turning the image right-side up! Every time we look at something, the image is upside-down until our brain flips it over. The lens is undoing that.
[* black] But why??? You know that little hole in your eye that allows light through? The pupil—yes that's the one! When light passes through your eye's lens and through that central point, it is then projected onto your retina…but upside-down. Your brain must then flip the image back over, until viola! The image looks right-side up.
