I need reading glasses only. I live where there is no eruv. I keep a spare pair in the synagogue, but can I carry my glasses on Shabbat when I'm praying in a different synagogue?
AskTheRabbi.org answered:
Rabbi Neuwirth, Shmirat Shabbats Kehilchata, writes that aside from making sure that you leave a pair there before Shabbat there is no real option to be able to take them with you to the second synagogue.
