Which situation would cause the eye to become less myopic overtime(With eyes -3.25 myopic)? If the option was done for 1 hour a day for 3 months.

Wearing -2.5 lens while watching tv 6' feet away an hour a day. Undercorrected where the tv screen is slightly blurry but quite watchable.

Wearing no glasses while using the computer at 11" inches away. Anything past that is blurry

if an excessively strong plus works for you, then thats great.

The problem is that we haven't enough people who trying to reverse their myopia and we haven't enough scientific studies on human.

To say that strong plus lenses don't work, we need testers.

Steven said that strong plus lenses work on him.

Hi Video,

Thanks for your sincere report.  Based on Dr. Alex's calculator, you are indeed about -3.5 diopters (40/12) nearsighted.  (Just an estimate.)

Your evaluations on choice of a reduced minus - are correct.

cannot read the monitor at 20", I have to be at least 12" from the monitor to effectively be able to read the texts on this forum.
I cant read the 20/200 at 20 feet. at 10 feet I can read the 20/200 and can somewhat make out the letters of the 20/100 but both still have heavy bluriness to the letter.

Although the visual stimulus in all cases should be similar the convergence (stress) is different.

The closer you look the more your eyes need to turn inward for fusing the 2 images causing some stress to the extraocular eye muscles.
Also your brain is used to accommodate automatically with increasing convergence (AC/C ratio). So you are also having more mental stress to override it.

According to Dr. Frauenfeld focusing at far (he calls it focus pulling) is more beneficial.

so a plus lens doesn't get rid of the convergence stress? but this can be achieved with prisms.

Maybe someone can do the prism calculation for reading glasses?
 
Not sure if it works for all of the convergence. There once was a device named "Myopter" for completly canceling out accommodation and convergence at near.
