I thought that this was a article worth reading. I thought it was very touching that a blind man could finally see his wife again. I am a little confused on how the patient sees the person. In the video it showed a pixelated picture. I assume it was him looking at his wife but, I couldn't tell how he understood what it was. I found this article very cool and touching at the same time.
It is incredible how they used an electrode to replicate the optic nerve. Basically, our eyes work as cameras which pick up the mages, and send it to the retina, which sends it to the brain through the optic nerve. We can replace the eye with a real camera, and use an electrode to send the pictorial signals. I wonder if since cameras can see much further than humans, if it would allow the person wearing the bionic eye to see extremely far distances.
This was absolutely an amazing achievement. There was this one girl who claimed that a kind of soup could cure blindness. Don't ask me what she was thinking, but now, a man can happily rejoice with his wife. The "camera" in our eye works very well most of the time, unless poor vision, a birth defect, a car accident that was hard on the eyes, etc, affects it. This man was able to live while being able to see his family again. Maybe the replaceable bionic eye had special effects as well as defects. The pixelated photo in the article was, I think, the view from the man's eye. That is a design flaw right there, but, maybe, they can upgrade it to maybe see extremely far, or to see colors better, maybe to be able to have many different abilities with it. I assume the process of getting the eye in was difficult, but it's obviously worth it when science saves the day again, and helps a man dearly in need of sight. There was once a boy named Ben Underwood, and he had to have his eyes removed because of a cancer, and the way he "saw" was he made short clicking sounds with his tongue and somehow he got around with no trouble at all. The unfortunate part was, this could have helped Ben tremendously, but he passed away somewhere about 2007, I think. Using an electrode in place of the optic nerve was incredible, it sends the image to the retina, which processes it to the brain. The electrode, however, is not the same as a human eye, so it looks weird, pixelated, or even blurry, when you are blind and have a bionic eye. Thanks James for the article. Maybe the next one can have something to do with a voice implant thingy for the people in this world who are mute....
I thought that it is an astonishing achievement that scientists can make a bionic eye. I think that is is an even greater achievement that they can give people back their vision. I agree with Jenna that the pixelated picture wasn't clear and I couldn't understand it, but it seems like Mr. Zderad was able to see his wife. It was so emotional for the family. Seeing how emotional they were makes me realize how important these advances in technology to restore vision must be to them.
A bionic eye seemed so impossible until I read this article. This video was so touching. The man has been through a lot, and for him to even see pixels is a huge achievement. All it took was one electrode chip. The blind man and his wife were so happy. (I would be too). I agree with Jenna also. I really couldn't see the picture either. I think that this article was a very heartwarming, and I hope that the man will get some more of his vision back.
I thought that this article was very heartwarming, and interesting. I do agree with Jenna and Ella about the picture being hard to see. I wonder if in the real world you would have to interpret what you see with the glasses like this man did. I wonder if he just happened to know that his wife was walking in front of him from sense of presence, and if he actually in the world would be able to see random objects clearly. I think this is a great achievement and thanks to James for giving us this article.
The thought of what technology has given us up to today is amazing. It is stunning that the idea of the prothesis is replacing the function of the photoreceptors by sending signals directly to the optic nerve. When he saw, it was not only touching, but seeing (bad pun). This is a good article. It isn't very detailed; I would like to know more about how this works, but for now-amazing.
I think this article is very interesting. It taught me that a condition called photoreceptors, is a condition that is inherited, and suffers the lossage of cells in the retina which is in the back of the eye and it is sensitive to light. People with this condidtion can only see very bright light so Dr. Iezzi created a devise, or a bonic eye, which helps blind people with photoreceptors see at least some shapes of light.
I think Dr. Iezzi made a life-changing for many blind people around the world. This is an amazing article and an even more incredible discovery. I think that if Iezzi perfects this method, it could be world-changing.
It is brilliant that Dr. Iezzi made this bionic eye for blind people with a condition that rendered them blind and only let them see very bright light. It was very touching when Mr. Zderad could finally see his wife after a decade. I understood that he has been through a lot and had to endure lots of pain being unable to see his wife and having to quit his job to become a blind carpenter. Even though I couldn't see the pixelated image on the scree, I knew that he was looking at his wife and that he was very excited and happy to see her after all these years. It was a brilliant idea on Dr. Iezzi's part for thinking about the bionic eye and making it happen. I believe that the bionic eye could change the world for blind people.

Sorry, bionic and condition.
