However, this is only one of several mobility options used by visually impaired and blind people. You will be exposed to sighted guide, white mobility canes, and dog guides. It will help all if you remember and follow some simple points of courtesy. First, people with vision difficulties are ordinary people, just blind. It isn't necessary to raise your voice or address them in a child like manner.
Many blind people have excellent voice recognition.
However, just as a sighted person may remember a face, yet forget a name, the same can occur with voices. This simple courtesy will avoid embarrassment for both parties. On a similar note, it's nice to know who's in the room with you. Please speak when you enter and exit. It's helpful if others with you are Introduced.
