How Blind People Actually See the World
How do blind people see the world? Do blind people see dreams? Most people imagine that what the blind see is complete blackness. But, it’s not that “black-and-white”, so to say. There are different degrees and causes of blindness that affect what blind people can see. What's functional blindness? When a lot of us think of blindness, we only imagine total blindness. But there is something called functional blindness as well. It means different things in different countries. In the US, normal vision is 20/20, and the higher the second number, the worse the vision. A person with 20/200 vision is considered to have functional blindness, which means they can see at 20 feet what a person with normal eyesight can see at 200 feet. It could also mean the person has a visual field of 20 degrees or less, whereas normal is between 60 and 100 degrees. There are different types of functional blindness with varying levels of severity.
