As far as working with someone who is blind or visually impaired the NCPAD suggests the following guidelines.
1. When communicating with clients who are blind or visually impaired, speak to the client when you approach him or her.
2. State clearly who you are; speak in a normal tone of voice.
3. Never touch or distract a service dog without first asking the client.
4. Do not attempt to lead the client without first asking; allow the client to hold your arm and control his or her own movements.
5. Be descriptive when giving directions.
6. When seating, gently place the client’s hand on the back or arm of the chair so that the person can locate the seat.
7. When conversing in a group, remember to identify yourself and the client to whom you are speaking.
8. Tell the client when you are leaving.
