Do any blind people use Protonmail despite the CAPTCHAs?

I’m not blind but I browse with images disabled. This means I can no longer login to Protonmail because they push CAPTCHAs. I know some CAPTCHAs have an audio option but I just get a blank box from Protonmail’s CAPTCHA. So I was wondering how blind people deal with that, or if they are simply excluded from using #Protonmail.
