Many people use the cane for visibility and to inform other people that they have a vision impairment, not just because they “need it” because their vision is so poor under those conditions. That’s why it is also called an identification cane. My husband uses it when he deals with traffic and busy streets— his vision is generally pretty good in those circumstances but it lets everyone else know to be cognizant of him.

If you used your cane, people would realise that you have a vision impairment, so they might move out of the way.

You don't have to pigeon hole yourself so strictly. If you are feeling uncomfortable in the hallways navigating crowds, you may find you need it at other times.

Well if you're having problems, I'd say use it all the time.
