Hi Cristina,

So in situations where you don’t currently use glasses, stick with that. Already great.

Assuming that you have no issues with the phone at any distance with the current glasses, I’d be tempted to just go down by 1.25 diopters for a start for differentials.

Yes, the eye strains faster because of the higher astigmatism. You could reduce 0.25 to 0.50 of the existing cylinder for differentials, though how much of it you may need is always a bit of a guess. 🙂

The first differentials, always a bit of an experiment anyway!
