I can't speak for the program requirements (I don't attend HFCC), but I know several people currently in HFCC's nursing program with glasses, so if it is a requirement that you have 20/20 vision, there might be a way around it?
I attend HFCC. You do not need 20/20 vision. I don't know what the cutoff is, but you need to pass a physical before attending. They'll test colorblindness, range (blinking lights on each side) and then you'll read a wall chart from a distance. I didn't get any 100% perfect and I'm still here. I did my physical at Midwest.
