Apparently, Clostridium Botulinum causes permanent vision loss by forming a cyst behind the eye in the eye socket. This cyst presses against the eyeball causing refractive errors.
botulism 320 1655(sq) 8500(sq) 177-979 Hz
Epidermoid Cyst 120 250 8620 1725(sq) 8250(sq) Hz
and combined,
usually too many frequencies in a single audio file is less effective.
Good luck.
After hours or so, when the bubbly phlegm is gone, try this,
ametropia (eye faulty refraction) 240 700 1583(sq) 2975(sq) Hz
only after the underlying disease that cause the faulty refraction condition has been removed.
Good luck again.
