I always love the fact that your vision is not complete... there is literally a portion of your eye that cannot 'see' anything, due to the absence of photoreceptors (it's in the back of the eye, where all your other receptors have their axons passing out of the eye and into your brain.

That means that when you look at anything/everything, both eyes have a blindspot. But you dont see that. You see a total, complete image. It's amazing... your brain 'completes' the image with colors, shapes, contrast and contours, based on what it expects in in that blindspot. Youd never know it too.

I fucking love neuroscience.
