'Smart glasses' help fix failing vision

That looks impressive, a lot less bulky. I know applications are wider than for people with vision loss. Especially if it's opened up to application development through Android or similar like indicated.

Actually, yes. Most doctors would call it fringe science, but I've been able to improve my eyesight with what's called Plus Lens Therapy. It has you wear glasses that are the opposite of those you've been subscribed, or that are significantly less strong, and using them while actively trying to focus at the edge of blur, e.g. by reading a book and keeping it far enough away so it's ever so slightly blurry but not too blurry either, forcing your eyes to clear the image. It's not clear why it works – do your eyes actually start changing their shape, or is it simply the eye muscles that get stronger? – but if you're willing to put in the months and months of effort it requires, for many it does help.

It's highly debatable that you can fix eyes like that. Optometry developed historically as a practice of prescribing eye exercises for "vision therapy," but most optometrists these days measure refractions to fit corrective eyeglasses to their patients, just like ophthalmologists. I know several people, a few of them quite closely, who have convinced themselves that they are improving their vision by eye exercises or by refraining from using prescribed corrective eyeglasses, but what they are mostly doing is kidding themselves as they go through life with needlessly blurred vision.

The way to be sure whether or not eyes can be fixed like that is to set up an experiment with random assignment to treatment and control groups, and to have investigators who are "blind" (an unfortunately coincidental word in this context) to each subject's assignment to this or that group test their vision carefully. I confidently predict that any treatment effects found in such a study with the methods you read about on Reddit will be of small effect, of brief duration, and obtained at more trouble than the improvement in vision that comes from wearing prescribed corrective lenses.

It's been shown possible to neurologically improve eyesight by training your neurons. This wouldn't fix any underlying problem with your eyes themselves though.
