Currently I’m using -1.0 differential and -2.5 normalized. So my difference is -1.5 diopter and it allows me to use screens at about 40-45 cm.
I choose this difference because in the past my naked eye was not enough to read books or use phone. And I did a lot of the latter, so wanted a differential which allowed me to use it at the edge of blur. But things changed and nowadays I use my phone a lot less, and even if I use I can use it fine without any glasses. I thought that “naked eye for screen” is really close, but realize that’s a bit away with currently about 33 cm edge of blur. So I was thinking about maybe switching back to stronger differentials and pushing back my screen farther.
So I got curious what setup people use? I’m interested in:
- what’s your current differential
- what’s your usual screen (close-up) distance
- what’s your normalized or how big the difference between your normalized and differential
If you already don’t need differential than you can contribute with giving the data about the last time you used differentials
