I'm a programmer, I look at the computer monitor probably about 8 hours per day. What I did was that I wear a glass with weaker prescription so that when I look at the computer monitor, the characters are slightly blurred but I can still read them. I did this for about 6 month and my prescription went from -5.75, -5.25 to -4.75, -4.25. Actually when I started even with the -5.75, -5.25 prescription my vision is about 1.2 or so.
Unfortunately this technique seems to only work at the beginning. In the months following the first 6 months my vision didn't improve anymore so I stopped it. But I consider spending $300 to knock off 1 point prescription from each eye quite worth it.
By the way I never got any headache from wearing weaker prescription glasses (and I did get headache before when wearing stronger prescription glasses). Actually I found it comfortable to wear weaker prescription glasses when reading, because my eyes don't feel stressed. That is actually the optometrist at Costo suggested to me.
That is not physically possible.
Maybe (and that's a big concession, I'm very skeptical) it could work with kids, with still-developing eyes. No amount of glasses trickery will reshape your cornea in adulthood.
Other than the physical world constraints, if this hypothesis was true, people's myopia would never progress, as you would, by definition, be wearing lower prescription glasses if this happened, so it would self-correct.
The only thing this will get you is a headache.
