Let’s do a two simple experiments First experiment is keep your right hand straight like this and then keep the left hand like a circle Now, look an object which is opposite to you through the left hand hole Now slowly bring your hands closer but don’t bring so closer or move far. Look the object from a medium distance Just keep looking After some time you can see a hole in your right hand and you can see the objects which is behind the right hand Did you see it clearly You can see the objects behind the right hand. How it is possible? Did a hole created in your right hand? So, this is one experiment Regarding the second experiment, I will tell at the end of this video. You can try at home Hi, I am your Mr.GK Hi, Mr.GK My name is Sai Siddarth and I am studying 2nd Std I have two Eyes but when see a star, it shows as one star The question is very logic, even I had thought when I was kid Okay first let us understand our vision system first we can understand easily if we knows how our eyes and vision works. Whenever we see an object, the light from the object will reach our eyes It crosses the outer layer of eye which is called as Cornea and then it crosses the Lens and enter and in the back of our eye we have Retina. In that Retina area, approximately 13.5 crore cells are present That 13.5 crore cells will convert to electric signals. The object will reflect upside down there. The signals are converted and sent to Optic Nerve which is nerve connecting to our brain It will sent to the back of our brain Our brain will change the image now and then using straight processing and understand. So the signal goes from our two eyes You can consider this in this manner Consider, if someone takes you photo from one side and another from other side If you keep the photos together in photoshop you will get the depth of yours actually you get the 3D image point. Normally if you see with one eye then it can be said as 2D image because you cannot measure the depth. So, our brain will continuously get the inputs from both our eyes it will get two inputs and it will merge and it was practiced for long time to give us one vision it knows it very well. what your brain actually does is it takes the input from right and left eyes and processes it. Brain provides us as a single image. Only because of this we can find the depth and how far the object is present. So only because of that when we see an object with one eye it looks like 2D we can’t exactly measure how far the object is present? An example for this would be Try climbing the steps with one eyes closed in a new place, you can climb up in regular places If you close your one eyes in a new place and try to climb you will stumble because you can’t judge the height. Overall both eyes cover 180 degree so if you close one eye and see we will see from here to this end we would miss 30 degree angle in this side Like that only, if to have 30 degree extra angle the eyes are placed like this If you see chameleon, right and left eyes they work completely different they both will be in extreme left and right ends. It would be due to the evolution change to defend themselves from other animals and to run if not other animals would easily hunt it down. So it need to be alert and need to run anytime It should be more conscious, so the eyes structure are the eyes work separately and cover more angle. Okay I was telling about second experiment, that is take the pen cover like this close one of your eyes and have the pen in the left hand and keep the pen cover like this then move it closely and try to close the pen with pen cover It would be very difficult because only with two eyes we can process the 3D and know the depth and the distance so that we can easily close the pen with its cover You try this and mention in the comment whether you can do it correctly or not If you have done it, then it means your brain is working super. Have you seen muscae volitantes? Laughing Okay. It is nothing. Have you seen Floaters? Just to tell you a bonus information That is a place where there is a mist or place which looks white or place where it is so bright or if you see the clouds you can an object which would moving transparently You would not know what is that? It would be small You can see this even if the screen is bright If you see in the left, it will be in the left and if you move right it will be in the right. up and down, where ever you see it will follow you If you stop suddenly, then it will slowly fall down It will look like Floating This is called as Floaters. Many of us think that it is a disease or something fault and gets frightened. Even when I was young, I have played with that by letting it here and there. In the eye ball, the light travels from the Cornea and while reaching Retina and an object in the middle. You are seeing the shadow of that object. It could be a blood cell which stored blood or a small protein or small tissue anything might be which is small. So you are seeing the shadow of that only as uncleared and disturbed image. If you look into your eyeball, the top layer is made up of liquid You can feel the liquid when you close and open your eyes some times there will be water coming out of eyes Eyes needs such humidity compulsorily. It just like how a cycle which continuously work we lubricate with oils. in same way, we can say eyeball moves freely due to that liquid In such situation, when the object sits on the top it would present on the fluid and it looks like floating where ever we see. So, in our eye, eyeball also has blood movements In between our vision, we see the shadow of some object which is present. We see that as disturbed image.. You can see this image only if you focus more. But, when you are normal it will not disturb your work. It is because our brain was practiced to ignore this image. So, when you do your normal work your mind will not consider this and will not focus When you wake up in the morning you would warm-up by moving your hands, legs and heads to activate. Like that activate the eyes is necessary. It is not only to be done in the morning, whenever you find time every two or three hours, you can activate your eyes. What type of activity can be done? I have mentioned simple exercise in the video which is present in description You have to rotate your eyes in all angles fully. You need to see round and round You need to focus an object by moving nearer and far. You need to change the focus between your thumb finger and an object at 20 feet away So there are many small exercise which will increase the blood flow and activate your eyes Also, this helps us to sharp our eyesight So, I have given such exercise in the description. You also watch and do it. So, if you would like to know about your body parts in daily activity mention it in below comments I would met you all in Saturday evening with another interesting video. There are lot of things which we need to learn along with the kids So stay connected with Mr.GK. Thank You.
