Use it at various distances for common tasks. You will see which strength for what application.
And Stomachmonkey is corret. Buy the big packs for cheap on Amazon and spread them around the house, car, office, etc. Buy extras, cause the cheap ones break... |

You don't want to buy and use just one strength.
If they are too strong for the application you'll end up with a headache.
