Hi, While most people with vision loss have some vision, you shouldn't assume that they can make out where you are and or even who you are when both of you are in the same room.
Identify yourself by name when you start talking. For example, "Hi, Jane, it's Sophia."
Speak clearly and directly, and look at the person when addressing him or her.
Use natural conversational tone and speed. Unless the person has a hearing impairment there's no need to raise your voice.
