After some time of monitoring my cm measurements it looks like I found what creates more and more myopia in my eyes: the enemy comes at night, because I clearly see that my cm measurements are much worse at morning after sleep: the mean numbers are 0.25 more sphere, but sometimes it goes to about 1.25 more sphere than in evening or right after long distance vision trip. For example, 2 days ago, when I looked at nose for a long time, about 3 hours maybe (because I was done enforcing my eyes to look straight, at the next day vertical lines were very blurred at 12.5 cm (that corresponds -8, a usual sphere value for right eye). I put test image closer and closer to eye, and the result was: 10.9 cm, that’s about -9.25! After about 3 hours, it went back to -8. As well, it was hard to look in contacts: there were two images, each blurred like I see without correction, really! Yes, maybe 20% less blur, but it was hard to read big enough (5 cm) text from 1 m.
I remember myself that right after waking up, even a long time ago, the first thing I seen was my (single) nose. I used to see a lot at it, it was very comfortable for me.
Yes, basically my eyes think I look very very close nights and nights for ~10 years? Sometimes my eyes look rather at sides than at each other when I sleep, though, but I don’t know how much they do first and second. There’s no need to do first for long, because even 30 cm close up worsens distance vision enough (immediately after it). Shortening of internal rectus muscles (convergence) turns on accommodation (if extreme convergence, then maximum accommodation), no matter I need it or not.
@Dlskidmore, perhaps you’d really want to seriously look at it, because my opinion is that I am not the only one person who has such things.
@FMR, I can really have “high myopia ciliary spasm” you talked about - you see that in fact I used accommodation a lot due to this?
