Vision

When I was little I didn't really understand that my sister was not able to see things well without her glasses. She could open her eyes and look around and see things just like me when she was younger. But after a while her vision got worse and worse until, she had to wear glasses. Although she isn't blind, without her glasses, she can only see things clearly around a 6 inch radius, everything farther than about 6 inches is just a blur to her. She isn't blind or unable to see, but without glasses, she can't do anything. Yet when she takes her glasses off, she can recognize things, even if they are blurry. On the other hand, Mike May is a 60 year old man, who is perfectly normal just like us. But when he was three, a chemical explosion caused him to lose sight. But after 43 years of total darkness for him, he was able to see through a surgery operation. But even though he was able to see clearly and well, he couldn't tell what all the colors and shapes meant. Although he could see, he didn't have the sense of vision. Because he hadn't seen things for 43 years, he could not interpret the shapes and color. I thought this was interesting. Because although, after a while, Mike was able to see, when he was first able to see, he was not able to see anything. This means that after not using a part of your brain for a really long time, you will no longer be able to use it even though you have the ability to do so. But with practice, you can eventually use it once more. Even if a blind person is able to locate anything in their room, and be able to walk around without bumping into everything, they will not be able to draw a 3D map or view of their room because they cannot see, and if you cannot see 3D you won't understand it. They only know 2D because they haven't seen the actually room, they can only feel it. I think that in order to cure someone of a disability they had for a long time. You must not only make them able to do something again, but you have to teach them the concept of the ability that they have never been able to do. Since a blind person, cannot see anything, and cannot understand the concept of seeing at all. Then in order to restore their vision, you need to start early on, you need to input images in their head. This is probably not possible with the technology right now, in the future, I hope that people will discover a way to cure these kinds of "sense" disabilities. But still even just allowing people to be able to see is an amazing feat.
