1 00:00:05,490 --> 00:00:15,210 So, here in the next image, you can see a summary of all the parts of your eye. 2 00:00:15,630 --> 00:00:27,829 So, I repeat, as you can see in this white thing that we have here is the cornea, a layer of protection, a transparent layer of cells that protect your eye. 3 00:00:27,829 --> 00:00:41,450 Here we can see the iris, the colored ring that can open and close a little hole, a little space that is in the middle so light can enter, that is the pupil. 4 00:00:41,450 --> 00:01:01,950 The pupil is the hole so light can enter inside your eye. The lens that are this transparent crystal thing that we have here, when the image passes through them they do two things. 5 00:01:01,950 --> 00:01:23,909 The first one is put the image upside down here in the retina, and the second is control if you see properly or not. Focus the image like a projector, okay? If the lens don't work properly, remember that you need another lens that are the glasses, okay? 6 00:01:23,909 --> 00:01:33,409 The retina, that is all the back part of your eye, takes the image upside down and with 7 00:01:33,409 --> 00:01:40,790 a special sense it detects the colors and the light of the image, with combed cells 8 00:01:40,790 --> 00:01:44,890 and rod cells to detect colors and light. 9 00:01:44,890 --> 00:01:52,030 And the retina transforms this information into electric signals, nerve inputs, and puts 10 00:01:52,030 --> 00:01:58,890 this information in the optic nerve that transmits the information to your brain, okay? 11 00:01:59,870 --> 00:02:02,650 Maybe with this video you understand better. 12 00:02:03,209 --> 00:02:05,329 As you can see here, we have a man. 13 00:02:05,569 --> 00:02:07,689 That is the one I'm going to see, okay? 14 00:02:08,409 --> 00:02:15,250 The light goes to the man and reflects and goes into my eyes. 15 00:02:15,250 --> 00:02:22,189 The light passes through the cornea, enters inside the pupil, and passes inside my eye. 16 00:02:22,870 --> 00:02:32,189 It crosses the lens that are here, this crystalline thing that we have, and the lens do two things. 17 00:02:32,330 --> 00:02:40,590 They project the image upside down in their retina and focus so you can see properly and you don't need glasses. 18 00:02:40,590 --> 00:02:47,590 So they focus the image and put it upside down as you see here in the retina. 19 00:02:47,590 --> 00:02:57,590 The retina that is this part detects the colors and then light and puts this information in the form of electric signal 20 00:02:57,590 --> 00:03:05,590 and puts this information in the optic nerve and the optic nerve sends this information to your brain. 21 00:03:05,590 --> 00:03:09,590 And the brain puts the image in the correct position. 22 00:03:09,590 --> 00:03:16,870 okay okay so i hope you like the video and i hope you understand proper 23 00:03:16,870 --> 00:03:21,629 i hope you are fine and see you later bye
