Join the club, although my ears are reversed, ie. my right ear is virtually deaf, and my left ear is probably around your level of 60% (I suspect a bit less). You’d have no sense of direction with sound either. If a plane flies overhead, you’ll have to look all over the sky to find it. Or spin around when someone calls out your name, and hope you recognise them.
But I was born with it as far as I know, and have been wearing a hearing aid since I was a kid, so I’m used to it, and don’t actually pray for healing (apart from a comment occasionally - “You know, Lord, it’d be nice to get full hearing at times …”).
But for someone who has lost their hearing suddenly, it has a very big impact, particularly in the social area. And I don’t care how much marketing the hearing aid companies do, I’m still cynical when they claim they can clarify conversations in a crowd for instance. I’ve been wearing a hearing aid for decades, and I know what they can do, and what they can’t do.
So I suppose you could pray to Francis de Sales et al. To be honest though, the only time I have heard of someone getting their hearing restored miraculously was that of the Sister who witnessed Mary at Akita in Japan in the 1970’s. And even then it was a protracted process. No doubt there are other cases, but I haven’t heard of any.
