Need advice for work-related situation?

So, I’ve been working at my job for 4 months and I have not disclosed to anyone I have a visual impairment. I can appear “sight passing”, I think they call it. I haven’t had trouble performing my job really, so the topic hasn’t come up. But I feel I should just to let others know if anything comes up, I don’t want them to be caught off guard by randomly finding out. I fear sharing will make others think different of me and that it’ll take away from who I am. My supervisor is asking question like do I drive or how I get to work. I’m gonna be hired full time soon and she seemed to question my ability to show up to work although I’ve always showed up. I just can’t legally drive in my state. I fear that me not having a license makes me look incompetent and irresponsible. So, I guess it may be time to be honest, cus after all, my visual impairment is part of me. I just fear people will dislike me or have prejudiced feelings and thoughts towards me for technically being “disabled”. I’ve internalized the stigma, so I’m anxious to bring it up, but it’s probably something they should know about me by now. Any advice?
