Got the email today that my new glasses from Zenni Optical have been shipped. They will be my first-ever bifocals. I got "progressive" ones, so it won't be obvious to the whole world, but mostly so the line won't be bothersome to me. I know that we have many people here older than me, any bifocal wearers - how was it adjusting to them when you first got them?

Just curious - I have worn glasses since the summer I turned 9 years old, so am used to a day or so of adjustment time, but have never had bifocals. Any tips?
