Our eyes are seriously rather remarkable when you think about it. Did you know, the entire length of all the eyelashes shed by a human in their life is over 98 feet with each eyelash having a lifespan of approximately five months. Our eyes are composed of over two million different working parts. While a fingerprint has 40 unique characteristics, the iris has 256 which is why retina scans are becoming increasingly popular for security purposes. An average blink is just 1/10th of a second, and you blink an average of 12 times a minute. Our eyes and the optic nerve are so complex that we have been unable to transplant them and rewire them successfully.
And, yet, despite all these mechanisms working together to give us sight, we are all at least partially blind. You may have 20/20 vision or corrective lenses, but each of your eyes has a blind spot. And, you know this. Even though the other eye tries to compensate for the blind spot, they can still get us into trouble from time to time.
