I guess the two nouns "sight" and "vision" would mean the ability to see things as in "She has good vision or bad sight." I use "short-sighted" and "bad-sighted" to talk about people who have problems with vision. There's the adjective "visioned". Could I say that someone is short or long-visioned?
Could please elaborate on it? Is it wrong to use bad vision for bad sight or short-visioned for short-sighted?
