For anyone who is curious, here are the terms used to describe those with partial or total vision loss:
20/70-20/100: visually impaired, low vision
20/200: legally blind, partially sighted
CF (counts fingers): legally blind, blind
HM (hand motion): legally blind, blind
SP: (shadow perception): totally blind
NLP (no light perception): totally blind
Just as there are varying degrees to signify hearing loss (i.e. mild, moderate, severe, profound), the same is true for vision loss.
Again, it all comes down to individual preference. No single person has the right to tell another what they should be called (especially if they are not deaf and/or blind themselves).
Whats count fingers and hand motion?
