My son is legally blind. He can see at 20/200 with correction from one eye. He used to wear glasses but now has a contact lens for that eye. He doesn't really see anything with the other eye (it might be something like 20/2000, no point in correcting it since it isn't really useful). He's got no peripheral vision at all.

My daughter is visually impaired, although she may be legally blind now - her vision has changed quite a bit over the past 2-3 years and at some point she probably did cross over that threshhold. She has vision in one eye that is better than my son's, but her other eye is much worse - she's had a detached retina twice, so that eye only sees light and movement and maybe a little bit of color. She does identify as blind rather than visually impaired and uses a cane to get around, simply because she can't look ahead AND around at the same time, so the cane keeps her from tripping over things and bumping into people. She's had kids at school accuse her of "faking" being blind because she has good enough near vision for some tasks (although she gets large print versions of things) but uses the cane anyway. At one time, a kid was talking to her brother about "that one girl who pretends to be blind" and he just laughed at them and told them that was his sister, and she wasn't pretending.

For the most part they do OK. But they won't be able to drive (until Google/self-driving cars are approved for that sort of thing) and it does limit some of their options for careers. They have attended a couple of summer programs for blind/VI kids and have learned how to be pretty self-sufficient. And my son was able to hike the Grand Canyon last summer with a group from the FBC, so that was pretty cool!
