Can drive (in daylight, at least) without glasses. Didn't expect that. Am learning to use eyes together again as they've effectively been "decoupled" for six months, with only one of them being in focus. It takes a bit of effort but they are beginning to work in tandem. The focusing muscles in the right eye are now so strong that it snaps into focus, even quite close up, if the left eye is closed. Left eye is comparatively weak as yet but it will get there.
Something I didn't realise is that most people who aren't short-sighted are actually slightly long-sighted (by which I mean hyperopic*, not presbyopic). It's very rare for an object at infinity to be perfectly in focus on the retina with the eye muscles completely relaxed; you just aren't built to that sort of precision. The eye nearly always has to adjust a little by focusing itself, but you never notice.
*where, with the eye relaxed, it focuses beyond infinity like some modern AF camera lenses
