There's a video online showing the abuse doled out to a deaf blind young woman travelling with a guide dog, whose sister lifted her mask briefly so that she could lip read. Even after the situation was explained, the abuse continued.
Richard Kramer, chief executive of the disability charity Sense, said his organisation had received “lots” of reports of disabled people being challenged for not wearing a covering. He said: “These experiences cause distress and anxiety, and lead many disabled people to feel they have to stay at home, where they become isolated. We welcome the government’s introduction of ‘exemption cards’, but more must be done to raise public awareness of who is exempt from wearing face coverings, so the public are on board and disabled people feel supported.
After reading some comments on here, I can only agree.
