Kellee posts an interesting experiment in the forum.
As a bit of background on this, she went to the optometrist, who gave her a much higher prescription than her own centimeter measurements would suggest. Confused about this, she went home and did this:
Neat, right?
You can just convert the optometrist prescription numbers back to centimeters, and then see how clearly you can see at that exact distance.
Everything is pin sharp, no matter the ambient lighting? Stays sharp even if you move back further?
That should tell you all you need to know about overprescription.
(I know, some caveats there, but for all practical purposes this works just fine.)

You've got your number
Now get the plan to bring it down.
Knowing your diopter is step one. The trial gives you the exact sequence to lower it — plus Jake's 1:1 review of your measurements.
Where are your eyes now? Tap your prescription:
