I just got lined bifocals for presbyopia and my first pair of bifocals so I'm having a heck of a time getting used to them. I still move my head up and down to be able to see clearly because that line drives me crazy. If I keep my head straight and look down into the bifocal; things are glary or there is a glare. Like they would look if your eyes were watery and trying to look through them. Glossey I guess. You feel like when keeping head straight and looking down into bifocals; your eyes go inverted or look towards your nose like when reading things are double vision. Am I looking thrpugh them the right way by looking up and down into bifocals without moving head.

I prefer the "plus" for reading, and verify my distant vision at 20/20 on my own Snellen. Thanks for your information -- but that is my choice.
