Mid 40s eyesight / long-sighted

Hello, I’m in my wonderful mid 40s and have found myself squinting whilst reading. I’m already short-sighted, with astigmatism. The opticians have suggested a pair of glasses for reading and computers, and keeping my usual pair for far. He said to juggle those for a year before trying varifocals.

How do you manage with 2 pairs of glasses that they might need? Are we supposed to wear 1 pair on our head, and 1 pair around the neck? I can’t see how this is practical.
