Not a stupid question at all. I use an assortment of accessibility tools. I can still read visually thanks to my absurdly large screen and equally absurdly large text in inverted colors. I can also hear (low-resolution sound quality) through a cochlear implant, so i use VoiceOver to navigate. To read more long-form text such as books, articles, etc. I use a refreshable Braille display.

Basically, I use a bit of everything because no one accessibility tool meets all of my needs. Better than nothing, I guess.

I should clarify something about deafblindness. Very, very rarely is a deafblind person totally deaf and blind. Usually they have some residual hearing or sight, and I fall into that camp.

Hope that answers your question!

Refreshable braille displays, maybe?

(not blind but found out about these and they seem pretty cool)
