00:00Oh, there you are!
00:10I was looking for you everywhere!
00:13Wonder what I do without my eyes?
00:16Hey, so why don't we talk about your eyes today?
00:21Yes, eyes help you see things, see colors and see this video too!
00:28So, let's talk about how your eyes work.
00:32Zoom in!
00:36Well, the human eye works no less than a digital camera.
00:41The fact that you're seeing so many things has a process.
00:45And I'll tell you what actually happens inside your eyes.
00:52This is the cornea.
00:54The cornea is the clear front surface of the eye.
00:58You know, it actually acts like a camera lens.
01:02You could say that this is the window that allows the light to get in.
01:08Next comes the iris, which is a thin circular structure in the eye.
01:16This works like a camera shutter, deciding what should be the amount of light that enters the eye.
01:24It passes the light rays to the back of the eye called the pupil.
01:31Which appears as a black hole at the center of the iris.
01:36It is the opening through which light enters the eye.
01:41Depending on the amount of light, the iris stretches and contracts the pupil.
01:47Just how the aperture of a camera works.
01:51Then comes the lens of the eye, which is just behind the pupil.
01:57Okay, do this experiment.
02:00Close one eye and bring a pencil close to the eye, which is open.
02:07Make sure you can see it clearly.
02:10Now, bring the pencil close to your eye.
02:14Bring it closer, closer.
02:18That's right.
02:19Now, does it become blurry?
02:22Well, this is the job of the lens of your eye.
02:26It focuses and defocuses, depending on how far the object is from your eye.
02:33Now, the light reaches the retina.
02:38This acts as an image sensor of a digital camera.
02:42Well, in simpler words, it converts the light that you take in into electronic signals.
02:50Then, the optic nerve of the eye transmits those electronic signals to the brain.
02:57Which lets you finally see an object.
03:01Well, the retina actually perceives the world as upside down.
03:07And it is the brain that flips the image back for you.
03:12Amazing, isn't it?
03:15Trivia time!
03:17On an average, a person blinks 17 times in a minute.
03:22An eye is composed of more than 2 million working parts.
03:28Hmm, how I wish our eyes could click photographs and store them inside our heads forever.
03:37But I guess they do.
03:39In the form of memories.
03:42So friends, see the world around you.
03:45And make lots of memories.
03:48Tune in next time for some more fun facts.
03:52This is me zooming out.
