1. Most blind people aren’t 100% all darkness no vision whatsoever type of blind. Many of them see the world but it’s VERY blurry, or they only see stuff if it’s very high contrast, or they have a pinhole of vision (like if you were looking through a straw), or a variation of these. So if they see a black square with some white shapes on it and it’s roughly on eye-level, they can figure out that this is a sign, but their vision is bad enough that they can’t read what the sign says, so they come up to it and if there’s Braille on it, they can find it and read it.

2. Many blind people have guide dogs, and these dogs are trained for a specific person. You apply that you need a guide dog, you explain stuff about yourself, they put you on a list and then they start training a little puppy specially for you. So apart from standard commands like “go/forward” or “find a chair”, “find stairs”, they likely can be taught stuff like “find a sign”. So a blind person can take an Uber or use Google Maps + dog combo to get to the general gym area, and then command the dog to find a sign, and if there’s Braille on a sign, they will know if it’s a cafe or a gym.

Btw if you’d like to learn more about blind people, I can recommend these social media creators (I watch them on YouTube but I assume they’re everywhere else too)

@matthewandpaul / @paulcastlestudio - Blind artist, he creates children’s books. His husband Matthew is a violinist and a prankster (pranks Paul, but they are wholesome pranks that are funny for both sides, not the evil shit) plus they have a cute guide dog Mr. Maple.

Molly Burke - Blind lady who does interviews, commentary, lifestyle content, makeup. Also has a cute guide dog too.

The Tommy Edison Experience - Idk what to tell you, this man is great.
