Marc Staal is struggling with bright lights and says his damaged eye might never regulate light properly again. Staal admitted the lights in Rangers' practice rink are hard on the eye. The defenseman is still optimistic about getting full vision back in the eye, but it's clear he'll likely never have the same use of it as he once did. Staal practiced with the Rangers for the second straight day Thursday, but there's no timetable for his return at this point.
