https://browse.feddit.de/ This is a link to the lemmy community browser. It looks like there are 7 communities focused on the blind. I am still learning how to navigate through the fediverse but maybe this will help you find or link to what you are looking for. I used the link and just searched "blind" hopefully the link will show that or you can use it as a search tool to find what you want.

It takes a bit to load. Not sure if it is the search tool or just my Internet being throttled.
