Strip the jargon away and this sounds like it's saying "wear weaker glasses" and the device is just a fancy way to still see normally while having a weaker prescription in your periphery?
Anecdotally, among a bunch of my friends who are (a) nearsighted, and (b) mad about sailing ships, spending a couple of weeks out at sea staring at the horizon will make a significant temporary difference to their myopia.
I don't know why sibling poster is dead, it seems a fair question and I didn't know the answer so I've asked them and will update when I get a reply.
Edit: The person I asked said they wore their glasses some of the time but also spent some of the time without (when they were climbing in the rigging etc.)
