Good example of social model of disability too, which I find the most useful way to think about it. You have an impairment, but because of access to an accommodation it doesn't normally prevent you from doing the things you need and want to do eg is not disabling. But in other circumstances, like not having financial access to vision correction, it would be. Whether a specific limitation is a disability or not isn't a feature of your body, but a function of your society's relationship to you.
