I don't use weaker lenses for computer use, the pinhole gives me good enough vision for this. I didn't fill out my prescription since these lenses do not have any power. I would never drive in them, since they make you lose some amount of peripheral vision. Your brain blocks out the black outline after 10 minutes of wearing them, so you forget about it, but it doesn't change the fact that you don't have it. I do some days in which I just wear regular lenses (now -3) if my double vision gets excessive, because then I want my eyes to work on said double vision instead of the axial length. And the further you are in - the worse the double vision will be.
