I haven’t heard of the series either, but like you, I’d say it’s not off to a great start.

It’s possible to do blind super heroes well. Toph from Avatar:the Last Airbender is my go-to example. She learned to use her powers in a unique way because she is blind, but they don’t fix her blindness (she still has issues like not being able to read print), and her character has more depth than just “the blind one”. Most blind super hero descriptions fall into just being a bunch of blind tropes. I like Daredevil, too, for the same reasons I like Toph, but some versions (looking at you, Netflix) have him developing his super power because he’s blind, and playing into other blind stereotypes (we don’t want to touch your face!)

Maybe these books do okay, but that first sentence suggests the author didn’t do a lot of research into the actual lived experience of blind people, or they wouldn’t have started with “I have super hearing because I’m blind”.

The opening makes it sound patronising but once it gets going it gets better
It doesn't play off the helpless blind person trope there are many characters that have disabilities and the relationship between them is why i like the books its a group of friends who can make jokes about their disabilities
Like my self i make jokes about my vision all the time
It takes elements from super hero media and elements of Harry Potter
I think blind people may relate to some parts
