Nicholas Boisvert steps out onto the ice confidently. His skate blades cut into the ice, holding their edge as he accelerates through a turn and speeds up the rink. He didn't expect to do this again. "I lost my sight in 2012, so it's been a few years," he said.
Boisvert, 35, grew up playing hockey. He played in high school at Richfield, Minnesota, and in intramurals in college. But he has Best disease, a degenerative condition that took about 80 percent of his vision in his late 20s. "I really missed hockey, and when I lost my sight it was really hard to adjust in not being able to play and then this came along and it gave me the chance to play again," he said.
