I'm not vouching for the product, but a little background context that might be lacking in general and that might help people in evaluating the claims made by the product:
So, they eye works pretty much like a camera - but it's not a "normal" camera: it's a complex dynamic self-assembling, self-tuning adaptive structure.
The fact that it's geometry is roughly static around a focal length that has sharp focus on the retina is a wonder of homeostasis with at least three known tuning loops:
1) the lens changing shape (accomodation)
2) a slower feedback loop adjusting the choriod (hence focal length) in the order of hours.
3) an even slower loop adjusting the eye geometry over longer periods of time.
The last two are not fully understood yet, but we have a a few good clues (even potential drugs targeting biochemical pathways)
If this product works it would be operating on the 3rd feedback loop

- eternityforest 4y agoWait, so it really is possible to acquire (at least temporarily) nearsightedness from looking at close stuff too much?
- philipswood 4y agoMy take is that it's completely possible that reading might be scrambling the long term autofocus mechanism that determines they eyeballs length in the long term.
