This is an interesting change in my life. I've had reading glasses before - that I used when working on computers, mostly - but not glasses that I've worn all the time. Making the adjustment is not as simple as I'd like.
I was told that these new glasses would make driving at night easier, and - so far - perhaps they do reduce eye strain from oncoming headlights, but they also give me lots of "spikes" from bright point sources that I find irritating.
Certain lighting conditions seem to result in light bouncing off the edges of the lenses and give things a slightly foggy look, too. I noted this most strongly while watching a concert last night. Depending on the angle I held my head at, the light off the stage caused the issue. But, of course, looking at the lenses directly against a uniformly colored background shows they are perfectly clear.
Condensation and rain clearly don't mix well with glasses either, and I've already experienced both of those, though not to any huge degree yet.
The most irritating thing, though, as to be learning to turn my head instead of just moving my eyes. The "sweet spot" with these lenses isn't always in the right place, particularly when I am reading. I find that I have to adjust the position of the book because my head can't comfortably point any farther down.
It's while reading that I am doing most of my experiments with what is and isn't in focus, and I'm wondering a little bit about that too. Sometimes, while reading I think that one eye - generally the left - is in focus, while the other is slightly out of whack. I move things around - head, eyes, reading material - and play games. (Close one eye, bring the reading material into focus with the open eye by moving reading material and/or head around. Switch to the other eye being open and see if things are in focus for it, doing the best I can not to move during the process.) I wish I had something conclusive on this issue, but I don't yet. Just an odd feeling that things might not be quite right, but it could just as easily be that I'm not yet adjusted to how to hold my head while using these new glasses.
I'm sure I'll work this out eventually, but it gives me new appreciation for the difficulties of full time lens wearers.
