With my differentials, I’m at 62cm with my left eye (when I close my right eye) and 63cm with my right eye (when I close my left eye). When I have both eyes open, it is 67cm with my left eye and 70cm with my right eye. I haven’t been measuring my centimeters with my differentials (I’ve been measuring without any sort of corrective lenses), but I’ll start doing that!
I do get a blur horizon with close-up. I used to get headaches when I first started, but they’ve since gone away. I try to sit at least 60cm-70cm away from my laptop, but it’s a little hard since my arms are short 😀
Let me know if there is anything else I should be doing. Thanks for the advice and for the great program!
