I didn't say that it was myopia did I? I specifically gave the glasses strength with the sign to indicate the kind of correction my eyes needed, and yes, it is far-sightedness, what else could it be with that particular prescription? Hence my need to wear them when working in the shop, I'm chance less without them doing any closer or detailed work.
The point was: once you start wearing glasses it accelerates the slide. + or - doesn't really matter all that much.
Do you use these for reading books/screens or also for distance vision? If only for reading, then what you are describing sounds like presbyopia, which is different from far-sightedness. Your accommodation changing as you age is a normal process and doesn't have anything to do with sliding myopia/hyperopia.
That's tricky. The 'light' version certainly helped also with different applications other than just books and screens and I used them in the car regularly, but the higher ones are useless for that because I can't keep all of the interior bits of the car in focus at the same time as the outside world so I drive without glasses, it also significantly reduces my dead angles due to improved peripheral vision.
So there may very well be more than one effect at work here. I can't really see the instrument cluster in the car but I know it by heart so it's not a problem and speed I can do by ear and get it well within the margin of error for speeding tickets.
I should probably get re-tested and maybe try bi-focals, but with the amount of driving I do right now I don't need to bother, the car is used so little I have it on a trickle charger to prevent the battery from going dead.
You probably always had some mild hyperopia that you were able to accommodate, but you lost that ability due to presbyopia. Perfectly natural. I would really recommend getting some multi-focals or to look into other solutions such as monovision.
