Hi. I'm online and happy to answer your question today.
it can take up to 3 weeks of full time wear for you brain to "adjust" to new progressive glasses. If you have have not had them this long, I'd suggest just giving them a try for that long and see if you adjust.
Also, the fit of progressive glasses is very important. If they are not centered correctly you may have problems. I would hope, however, that the doctor has checked this already.
Another issue is that you have to get used to "pointing your nose at what you want to see up close". Progressive glasses only have a very narrow "sweet spot" for near vision. To the side of this area the glasses do not have any power. From what you have posted it may be that you are looking outside of this channel.....this would cause near things are properly visible sometimes and not the other times.
So. What is the take home message? Give them at least three weeks for you to get used to them. If not then, perhaps, progressive glasses are not for you. Not everyone can adjust to them :(
Is there anything else you would like to discuss at this point or have all your questions been answered to your satisfaction?
