All humans have one or more natural/inherent deficiencies. All humans share natural deficiencies. For example, unlike the eagle eye, we were not born capable of seeing things over long distances, which is why binoculars were created for that purpose.
But some deficiencies are not innate and some people have these deficiencies due to diseases or other causes. For example, some people wear glasses if they are short-sighted.
My sight was great when I was younger, but now I have to wear glasses. A friend of mine used to have perfect hearing, but after an accident, his hearing was damaged and now he cannot hear very good. And I know another guy who after a plastic surgery lost his sense of smell. All these "deficiencies" have the feature I want a word for. They are not natural. We are not born with them. Not everyone suffers from them, and only some people suffer part of their lives.
- What are these kinds of deficiencies or inabilities called in English?
The word "acquired" has a positive connotation; for example, we acquire skills, not disabilities. The word "unnatural" has irrelevant connotations too.
The word "deficiency" might not be a good choice here. But that is not the point of my question. I want a word (an adjective) to use as opposed to natural in the aforementioned sense.
