About :

The human eye is the second most complex organ after the brain. We all know that our eyes work in a similar way to a camera. That’s true, but how exactly does the human eye work? How does your eye see? The human eye is an amazing organ! Did you know that, for example, your pupil isn’t a black circle on your eyeball – it’s a hole! It’s black because there’s no light inside your eye. Meanwhile, the red color that appears when you have your photo taken with a flash is caused by the light from the camera passing through and bouncing off the back of your eye. There, it’s full of blood vessels, so your pupil glows red! Or did you ever hear that the cornea doesn’t have blood vessels? The cornea gets its oxygen directly from the air – in other words, your eye breathes! But the cornea is filled with highly sensitive nerves. When it senses a foreign object, the fastest muscles in your body start to move. As the song goes, your eye is about the size of a ping pong ball. And inside this seemingly small organ, there are over 2 million parts working! #brightside Subscribe to Bright Side / @brightside Music by Epidemic Sound https://www.epidemicsound.com/ Stock materials (photos, footage, etc.): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru
