I think the last suggestion is outstanding.
Don't be too quick to assume that everyone knows everything about coping with low vision. You might talk about what coping mechansims you have used that work well for you, especially in school growing up, and in the workplace as an adult. Parents expecially will be looking for guidance as to what services and aids are available, and how to access them. Everybody's work experience is different, so we can always learn new tips from each other.
I don't think you could go wrong telling how you handle the social consequences of trying to get along in a fully-sighted world. For esample, when I go into a fast food restaurant and ask what kind of sandwhiches or drinks they have, they usually point to the small menu high on the wall way behind them, and tell me it's all there. If I respond that I know it's there but I can't read it, they often look at me as if I'm lying. So, short of hitting them over the head with a white cane, how do you suggest handling fast food cashiers? (Or do you just order a cheeseburger and chocolate shake, and forget about it?)
And while you may not suffer the same indignities we do because of hair and skin color,I know you do encounter similar ignorance in response to your visual limitations. (One of my personal favorites is, "You should go see my eye doctor.") That discussion is another way to develop a connection with your audience.
You get the idea. All the best!
