I have similar but different problems.
I can see very well close up. I can't see close up with my glasses on, I can not see far way with glasses off.
If you have a simple refractive error, the telescope focuser can take car of this.
If you have astigmatism, it usually does not effect high power views unless it is severe. It can
effect low power.
I think that maybe my view will be enhanced if I keep my glasses on while viewing at low power, but most often I find my glasses are always dirty or scratched, when I try to use them viewing through the eyepiece. Even though they are
AR coated, I seem to get reflections too. So I find I never use them viewing through the scope.
And, I can't go between scope and sky.
My best solution so fare is to have my glasses on a lanyard so they are always close.
Televue has a dioptrix system which is a lens that screws into the eyepiece to correct for astigmatism, but these are really expensive. I saw a man at a star party who made a poor mans diptrix system. He went to his optimtrist and
had a small lens ground and marked with the angle of astigmatism, he put this into a cell that he could attach
to the top of this eyepiece. To him it was an improvement over wearing eyeglasses.
If you can't read your phone, I don't know what to do about that. I have seen magnifiying Fresnel lenses for reading
books. Would one of those work for your phone???
Would it help if you switche from your phone to a tablet? 7 inch android tablets are almost free, the screen
would be much larger than your phone.
