But believe it or not, this guy is actually 100% blind and he figured out a way to see the world with his ears.

Who is he?

And how does someone see with their ears?

Hi, I'm Daniel and I don't need eyes to live in this world.

When Daniel was 13 months old, doctors had to remove his eyes completely and back then he was faced with a choice, spent the rest of his life blind or find another way to see.

So he developed his vision with the help of his ears by using sound in a special way.

Basically I just make tongue clicks and that creates echoes from surfaces and I use that information so that I can move around.

It's the same technique bats and submarines use and with enough practice, humans can master it too with only a few clicks.

Daniel can get a sense of what objects are around him, how far they are from him and even what some of them are made of.

And he can do it all even in the darkest night.

When people use light to see, they're basically using reflected light that bounces from surfaces back to their eyes.

I do a very similar thing but using sound instead of light.

So we have a structure here that has a roof: a pavilion.

And you can try it too.

All you need to do is go in a dark room and make a sound with your mouth.

Now by coming closer to an object, you'll hear the sound slowly changing, telling you how far the object is and little by little you will be able to make a map in your head of where you are, just like a bat.

You'll be able to hear that signal bounce from a surface, just like an echo locator is able to hear.

So it would sound something like this.

Thanks to his ears, Daniel can live a life of freedom.

He can hike, bike, cook, travel the world all on his own terms.

I'm 56 years old.

I have rarely needed anyone to do things for me.

I make my own decisions.

I live my own life and I see no reason that other blind people should be restricted or limited.

That's why Daniel decided to create a non-profit school where not only blind people, but also autistic children and sighted people can learn the techniques Daniel uses.

I've been learning from Daniel since 2018 when I moved here, he has really helped my confidence with being able to go out and navigate my world.

Daniel is inspiring.

Not because he can live without vision, but because he is a teacher who shares his knowledge with the people who need it the most.

What would you like to say to Daniel?

You are doing a wonderful job.

You've helped children and other people in the world who can't see, navigate their world, helping their parents understand, thank you for giving back!

Nobody can really see what freedom is, but thanks to Daniel, maybe you'll be able to hear it.
