Emission Theory

Until relatively recently, there were two camps of people when it came to eyesight: extramission and intromission. Those who believed in extramission believed that light rays exited the eyes causing sight, and those who believed in intromission believed that sight was the result of light entering the eyes.

First held by Empedocles, extramission theory was held by Plato, Euclid, Ptolemy, and even Da Vinci. I say this to say: this theory was not just passing idea. Some of the greatest thinkers in history held that it was true.

Of course, that doesn’t make it true. To me, that just makes it worth exploring.

My theory is not exactly the same as these thinkers. I am not proposing that we see by emanating rays from our eyes. I am just proposing that, under certain conditions, the eyes can emanate light.

Why do I think this? Because I think it helps explain some of the strangest unsolved mysteries of science: Why some animals have slanted pupils, Why birds crash into glass, How birds navigate, and why some people can feel eye contact.

I think these reasons in tandem makes a strong case. And lastly, I propose that you test for yourself in Smell with Your Eyes. Because I think that if you can experience it for yourself, you may just believe it too.
