For most people, vision is the most significant way of receiving and interpreting information from the world. Scientists still lack knowledge of the deepest inner workings of the brain, so there's no exact statistic to back this up, but most experts agree that vision is our dominant sense. But people with vision impairment experience the world through entirely different mechanisms. It's not better or worse - it's simply different.
Blindness does come with its share of challenges, though, considering most of the world is designed with sighted people in mind. As a result, living with limited vision means blind people have to find other ways to handle some things most people take for granted.
