I got trifocals last year, & I'm a tiny bit younger than you.
It took me about a month. The most difficult part for me was getting used to the change in my peripheral vision. Driving, shopping in supermarket aisles, & standing in front of a (small) classroom looking at my students was wonky for a few weeks. Nothing excruciating, though.
I didn't consciously feel I needed them. I just went to the optometrist because my eyes were tired, & I knew it was time for a checkup.
Now I can't look at things close up without taking my glasses off. And I have to hold things lower down when I read what's written on them.
