Dan Mancina is also known as "the fearless, blind skateboarder."
He wasn't born blind; rather, over the course of a few years, a condition slowly took away his sight until he had very little vision left. He describes it like "trying to look through a bunch of layers of saran wrap."
As you can clearly see, Dan doesn't let blindness hold him back. He still does everything from using the toilet to taking his girlfriend on dates to shredding with his skateboard.
