Healthy distance: Around 60cm is pretty normal. For context, too far means having a diopter gap that’ll get less than 1 diopter (diff – normalized), too close means too much convergence. Apart from that, make sure it’s ergonomically comfortable.
Avoid leaning in.
Never change both distance and close-up glasses at the same time, ideally. Follow the course exactly, no messing with distance glasses at all till differentials are sorted out. Very important.
If you like the current differentials as far as ergonomic distance and blur horizon, some active focus – then great. 🙂
