People who wear glasses are disabled, BTW. We need disability aids to function as an active part of society. If you wear glasses, you are disabled; your disability is just one that happens to be highly (if not totally) accommodated. It is generally considered reasonable to insist that you need your glasses and cannot cope well without them, and glasses are readily available and prescriptions for them not heavily gated. Touching or taking them without your permission is considered rude and cruel.
