If you think one would help you, try one.

I mean I'm 20/100 and never could use the cane since it slowed me down too much. I know of people who had one just to identify themselves as impaired. If it helps, it helps but I would first be shown how to use one more proper and see if it will actually help you

It's worth noting that my reading vision is about 20/40, I just have other issues besides. (Retinitis Pigmentosa)

If you think a cane would be of some benefit for you, it's worth a shot. However, if it were me, I'd want to make sure to get some training from an O&M teacher. That would not only tell you how to use one most effectively, but also teach you what your cane would and wouldn't help you with and better teach you what you do or don't need it for.

I got my first cane at 11, when my vision was much better, but I was still bad enough to be Legally Blind. It didn't really help me with social interractions at school, since carrying a big reflective stick seemed to make me more of a target for the crappiest kids at school.

I really don't care if you use one to help you, you shouldn't be worried about using it if you feel you could benefit. But canes can be a hassle, and you should be ready for that. People will treat you differently. You will get tired of having one hand occupied when you need to carry things. Your wrists can get sore. It will run into things and people in hallways.

If you need one, get the training first. Try one out for a while and decide for yourself. You're not going to be ostracized by blind people for using something that helps you.
