I thought that this video was really cool. Even though I don't have glasses I enjoyed listening to the science behind eyes. I loved the facts they talked about in this video like, when using a pin hole images become clearer just like a camera lens. In conclusion I found this video to be awesome and I would like to see more videos on the blog like this.
I think that this video is very interesting although I do not have glasses when you look through a small hole in your finger the image looks more focused. I think that it is very interesting how if you look through a tiny hole then it focuses your eyesight. It is really cool the way light comes in so if you have a small hole then less light comes into your eyes. It is also cool how that the more light comes into your eyes then the more messed up the picture will be.
What! My brain is hurting! Your fingers can help you focus. I can't believe it. This was the most helpful thing that anyone could have posted on the US1 blog. The idea of looking through your fingers which makes you focused is amazing. But how does that happen. I think that it is just nature. Oh alright, I don't know. Well, probably many different ideas of science are put together to create this specific one idea. This is only one of the many fascinating things that science has to teach us. Actually, now cameras aren't so interesting to me. I realized how they work. When using a pinhole, the quality of the image just goes up. That's how I think about it. Overall, this was a great and informative video. Yes, I put the period at the end.
I thought that it was really cool to learn that looking through a pinhole makes what you are looking at more clearly focussed. Even cooler is that it's not because the eye focusses any better but that the pinhole blocks light so that the image doesn't blur in the back of the eye. That's why the image is darker. You wouldn't think that blocking light would help you see something better but I guess it does.
I think that this is a really interesting trick for those with optical issues with lost glasses. It makes sense that the lens would see better than just a pinhole through the eye, which would send images scattered everywhere instead of focus, but I did not know that also occurred for the lens of an eye when your fingers are used as lenses! I now realize that the optical uses of items such as cameras and telescopes were built almost to mimic the lens of an eye, so as to get a focused image. I also thought that it was a cool fun fact that the eye can look towards one thing, and have the background blurry! This comes in handy for non-glasses wearers, too, should someone without glasses have a concussion or something else that blurs the eye. Unfortunately for me, I was not able to try the reading experiment in the video, for I do not wear glasses or have any issues with blurred vision!
This is amazing. It totally makes sense, and it is so helpful! No wonder squinting works! I'll have to test this out in class and see if it works. The physics behind this is really interesting, how light gets into your eyes and how your eyes and the lenses focus it. I personally don't have the most perfect vision, so this will be very helpful to me.
This video is really interesting how looking through a hole in your finger lets you see better and farther because it lets only a certain amount of light reflection into your eye.
I thought this video was very interesting. I have glasses, pretty bad eyesight, and occasionally forget my glasses when going to important or long events or places like school. Now that I have watched this video and tried the technique myself, I will do it when I forget my glasses. I thought it was cool how by making a tiny hole with your hands, you could kind of imitate or mimic the lens when the muscles are pushing against it to avert blurriness. I also thought it was cool that it seemed like camera's lenses are like our own lenses. But then it was also cool how if you instead of focussing on a picture, you create a pinhole or a small aperture, objects appear darker. This video was very interesting, the science behind retinas and lenses, and how even if you have forgotten your glasses, you can still make do with two fingers creating a "pinhole".
This was an amazing article, and I think that this "pinhole" idea could be used to drastically benefit the U.S.A. Like it was said in the video, when your eye receives light, it sends certain neural impulses to your cerebral area. In the right doses, this can give you an idea of the world around you, and will allow you to experience your surroundings. But when higher amounts of light are used, there is a neural overload which disorients and blinds you. The job of your eye lens is to make sure that this doesn't happen, to keep your eye safe from harm. Now, the U.S. military uses a type of grenade called a flash-bang. It is a small device, which, when activated, will emit a great degree of light in a small area. Flash-bangs disable enemies long enough for soldiers to attack them, or at least infiltrate the area. But this weaponry is just as dangerous to it's creators as it is to those it's used against. I think that, if done correctly, we could surgically modify soldier's optics to create a much darker image. This would allow for many different military technologies created, for example, flash rounds on an assault rifle. These bullets would disable all enemies in the immediate environment, and would not harm the one who was firing them, as long as the genetic modification was completed. Thank you for listening! Please reply with a rebuttal or other important factors!
This video was interesting. Such a simple idea and a complex idea behind it. I liked how they compared it to a camera, because it shows how much more your eyes are focused than a camera. This idea saves you over $100! Wow! You just have to make your fingers into a pinhole, and your eye will be focused! It a great idea, and is true, because when you're looking at multiple things at a time, you can't see everything clearly with only two eyes. Although, with a pinhole, it focuses your vision on a certain thing, and focuses extra.
I am glad I watched this video, because it is very useful. Even though I don't have glasses or contacts, it seems very useful. You won't have to spend a lot of money to buy glasses or contacts. Although if you don't buy glasses or contacts, it is just looking through a little "pinhole". It makes your vision only see part of the environment, so if I had glasses I would buy them. Overall, this is a good tip to know, but don't rely on this tip instead of having glasses or contacts.
I think that this is a really cool trick to see better. I like the idea of blocking out the amount of light that comes in. When they were showing an example of a person using the pinhole one part I didn't understand is that some parts were blurry because they were too close or too far. The reason that happens is because the light doesn't go throught the lens and meet at the same point. But if there is only one light source coming in from the pinhole wouldn't nothing be blurry? I overall think this was a cool and useful video.
Wow. This video completely took my by surprise. Honestly, I didn't even believe that it was true at first. Unfortunately I do not have classes so it was impossible for me to try it myself. However, once he gave an explanation and connected it to the lens of your eye and the light it made sense to me. In my opinion I thought this video was extremely interesting and very interactive. I wish it was a little bit longer, to give me time to deeper understand the concept. I really enjoyed how he made a connection with the appature of a camera, because that was when I truly understood the concept.
This didn't seem real the first time I watched the video. It doesn't seem right somehow in the sense that it is strange that you can use your ordinary fingers to see if you realize you left your glasses at home. I tried this the second time I watched the video. I had my friend hold up flashcards and I read them with glasses and with the pinhole thingy. It was so clear, it was scary! I thought that a piece of my lens got stuck in my eye! It reminded me of a camera lens before they even mentioned it in the video. Like Derek said, it is cool to think that if a whole lot of light comes into your retina thingy, that it will look blurred, but if you have a small amount of light coming in, it will look just fine. Since I have glasses, this was more about the actual experiment!! It amazed me to think that this wasn't something you could buy; it's something you can do pretty much anytime. If I ever forget my glasses, I hope I don't forget my fingers!!!
Mind. Blown. I am completely, utterly stunned about this video/idea and I would like to read more about it. I don't understand why people go through all of this trouble when they can just use their FINGERS to see. I get it for people how need reading glasses or have extremely bad vision, but for people who don't have either of those, you may as well just build a miniature contraption that has holes the size of pinholes. No more lenses falling our or cracking! This is just my opinion, and I am probably wrong.
I thought that this was really helpful especially because i have glasses. It makes sense that when you make a tiny hole on your eye it is more focused because when you look with the rest of your eyes the focus is broad and blurred but when you look at a specific area just with your pupil its much more clear. with this you wouldn't have to buy costly glasses.
I think this video is very interesting. I have glasses and it was really cool when you make a small hole in your fingers, and place it up to your eye, you can see a little better, since it focuses your eye more. Also, now I know astigmatism is when your eye muscles aren't working right. Overall, it was very informative.
This was a very interesting video. I can't believe that you can just make a small hole with your finger, and see the world clearly. This pinhole idea will greatly benefit the world. I also found the process of how light bounces of object to be interesting. This was very informative, in that if you had no lens on your eye, object would be smeared, and not clear. Overall, this article was very interesting and I will try to look into it more.
I agree with Jason, that the quality of an image goes up with the pinhole. I also agree with Conor that this could be beneficial to the U.S.A. and the armed forces (military). I just wish that this video would go into more detail on the actual process of the eye being able to pick up certain details. I felt that they only used a very basic outline of this in the video. Overall, I really enjoyed this video, and see how this could greatly impact the world.
I actually knew this. When I got the concussion, they told me to make my finders into a tiny hole so that I could see better. The theory behind it is that by taking out everything that could confuse your eyes. They often use it when people are having trouble focusing. I wonder is people can dent their lens, or if the are born with a bent lens. And when someone is born with a dented lens, why are they born like that? What cause that to happen?
I thought that this video was very interesting. I don't have glasses, but I think it is really cool about how if you limit your area of vision, you focus! I did something like this when I went to astrocamp. There was a small hole in the wall, and half of us were on one side of it, and the other half of us were on the other side of the wall. We projected their image onto a screen, and they were upside down and completely in focus. That is kinda like what this video was talking about, and it is really cool, just like everyone here said.
I think this is really interesting. I think this would change the revolution of glasses and seeing with this. This is so cool and I think that more people should know about this.
I think that this is really crazy. By now everyone probably should know that Sydney has contact lenses, and when one fell out, she tried it and it worked. I think it is fascinating now that I know the science behind it. This was an incredible video and now nobody will ever need glasses again (if they want to hold their finger up to their eye whenever they want to see something in focus!!!!)
This video was really cool. Although I do not have glasses, I see that when you look through a small hole in your fingers, the image looks a bit more focused. I thinks it's interesting that the more light that comes into your eyes, the more distorted the image will be.
I thought that it was cool that you can make a small hole with finger that acts like a camera lens but for your eyes because it can help them focus. I had no idea that you could do that, and when I tried it really helped me read the small text on the top of the part of the video when you can test it. I want to see more things that are very cool on like this on the blog
The video was helpful. I never knew that our eye had muscles to move the lens so we can see near and far away. The fact that you can look through a tiny hole is very cool, but I don't know if the strategy actually works because I don't know how to blur my vision. Some of the video though was unnecessary such as the pinhole thing. Everyone knows that light can only come in though one spot. I overall thought that this was a alright video that could be more specific with detail.
I think that this video is really cool of how it explains how we know the objects are there because we see them and because we focus on them. I never knew how important the lens on your eye was. Everything would be blurry without it. I think that video's like this should happen more often and I think it helps us understand more about the world around us. I think this video was incredible.
At first I really could not understand this video but after watching it a few times it really started to come into focus. Like Derek mentioned let me say that like him I do not have any glasses either so the parts of the video for people with glasses were kind of wasted. I got the point regardless. Just thinking of this I can see many places were it helps. For instance lets say you have a magnifying glass if you cut part of it to make it smaller and hold it up close to your eye it should be more effective(I did try this and you should too). It is just so simple and just so useful and because of this I think that this is probably one or maybe even the most interesting blog. I could go on all day about how useful this is but let me just stop right here because I don't want to get carried away
I thought that this video was really interesting! I've tried this and it really works, even if it is a bit darker because of the blocked light. Also, this is very helpful for people like me who have pretty cruddy vision and need glasses. My contacts are also often incredible irritating, and in a pinch(like maybe three times a week at my rate of messing up contacts)I will definitely use this. I also think it's cool that I now know why my vision is bad: because of those muscles not pulling the lens of my eye into the shape it needs to be in.

I tried this over the course of a week. Trust me, it works. Again, I am speaking from experience.
