Why go that furturistic? How about teshuvos that consider qeri'as
haTorah with eyeglasses to be valid? Here's a list taken from R'
Avraham Steinberg's "Encyc of Medical Ethics" pg 111 fn 92:

    Shevus Yaaqov 1 #126
    Tif'eres Yisrael, Kalkalas haShabbos #33, and Nega'im #2, Boaz #4
    Shaarei Teshuvah OC 426:1
    Mishpetei Uziel (2nd ed) OC 38
    Yechaveh Daas 4 #18 fn 13

Judging from the book, they make a chiluq RAS describes as glasses
not having an "/interposition/ for those precepts that require vision"
(pg 109; /italics/ in the original).

Apparently RSZA holds that hearing what a hearing aid's speaker produces
in response to a shofar making sounds in the room is an "interposition" --
whatever the original Hebrew/Aramaic was.

GCT!
