Mega's new video reveals a series of insane eye curiosities

Did you know that human and shark corneas are so similar that in the past, the eyes of these animals have been used to replace humans? Or that when we are in love, our pupils dilate and can be up to 45% larger than normal? And that the most active muscles in the human body control the eyes?

You can check out these and many other insane curiosities about the eyes in the new animation here from Mega Curious. By the way, if you enjoyed the video, be sure to subscribe to our YouTube channel - and give it a thumbs up at the end!
