How do blind people conceive of color, height, depth, nature, and other intangible phenomena? Tommy Edison can tell you everything about it. For him, beauty comes in the absence of both shape and size.

"People wonder a lot about my perception of things that sighted people see all the time," he explains on his YouTube channel. "You know, big giant things that I probably couldn't even get my head around."

Edison, who’s been blind since birth, naturally senses the world around him in a very different way. Without any type of visual input, his brain interprets space as an aggregate of sounds, scents, and pressure. In a new video, he offers sighted people a glimpse into his remarkable world.

“The sun I understand is, what, like 93 million miles away from earth, right? See, there are so many things like that I know about, but I just don’t know what they are,” he says. “I guess the sky is this big, open thing with nothing in the way.”

“You can just go and go and go,” he adds, laughing.

His lack of sight notwithstanding, Edison is also a film critic. His blog, “Blind Film Critic,” features reviews of hundreds of titles. Endorsed by prominent critics like Robert Ebert, his thoughts have appeared in several blogs and newspapers all over the country.

“I watch movies and pay attention to them in a different way than sighted people do,” he explains on his website. “I’m not distracted by all the beautiful shots and attractive people. I watch a movie for the writing and acting.”
