I have always worn glasses. I also make them for a living and am an ABO certified optician.
1. If it's just reading that you need glasses for, you can probably shoot without them.
2. If you need them for distance, I would recommend investing in a pair with just distance correction for shooting. Most no-line bifocals will get fuzzy when you turn your head. A lined bifocal might work if you can get used to the line in your sight picture.
3. Steer away from frames that go low on the face, the string needs that area.
4. For myself and in coaching beginners with glasses, a three under anchor with index finger at the corner of the mouth works well. Some archers will anchor higher and nudge their glasses up, and it seems to work for some. My issue with it is physics, lenses, and light waves. Moving the lens moves the focal point, this shifts the perceived image either down or up depending if you are nearsighted or farsighted. Lower powered lenses, it's probably not a big deal, but anyone with a higher prescription, it could be problematic.
That covers almost everything.
Happy Shooting with your new specs!
