Blind. The article is referring to blind and partly blind people. I'm visually impaired and thus I wear corrective lenses. This practice of applying euphemisms to every disability and impairment is stupid and unhelpful.
Very few people can't actually see anything, and so you are choosing your level of visual impairment as 'not blind' but someone else's at 'blind'. Someone else may put that line in a different place.
Fitting something not binary to a binary scale is hard.
One thing that we can all agree on is that they have some issue with their sight, e.g. some visual impairment.
Really, acuity is a spectrum and almost nobody has perfect vision.
Also, wearing glasses doesn’t automatically make someone visually impaired. If your vision is fully corrected with glasses or contacts, you generally wouldn’t be considered visually impaired. The term usually refers to vision loss that remains even with the best available correction.
