I wore them for a while, and stopped before they crippled me.

I didn't wear glasses until about 10 years ago. After a couple of years I got a no-line bifocal that the optometrist convinced me to try, of the type you're describing, whatever they're called. I never really got used to the head wagging (why couldn't I just move my eyes, not my whole head? Because the only part of the expensive lens that is ground is down the center in a sort of hour-glass shape. In the middle of the distance and close ground lens is a narrow "middle distance" area ground in). I couldn't focus through the viewfinder of my camera and suffered through a couple of years of fuzzy photos. And I felt like I was going to be crippled if I had to spend long periods of time at the computer, with my head tipped back to read the screen. One day I was talking to a friend, trying to find a spot in the lenses where I could see him. He asked if I was wearing that kind of glasses, because he's seen other people go through the same difficulty with the focal range.

I did two things. I got bifocals, the old-fashioned kind, with the line, like Rapaire says. I don't like having a line there, but it gives me a lot easier time figuring out where I am visually in relation to the glasses. The field of vision is back to the entire lens again, so I can move my eyes, not my head. And I got a couple of pairs of office glasses. This does use that no-line vari/multi/whatever focal feature with my Rx, but it only grinds them for middle distance and reading, and for some reason, when they do the Rx this way the field is more of the lens, not that hour-glass shape in the middle only. Now I look straight at the computer and glance down at pages or my hands, and everything is in focus. No tipping back the head.

Now, on those occasions when I see another glasses wearer tipping the head back to read a screen, I'll ask if they have a stiff neck. And if so, I'll mention asking about office glasses. It makes a huge difference.

I have one pair of straight distance lenses that I sometimes use for driving (my sunglasses are also that way). They also work if I'm lying in bed watching tv, so I don't have to see through the close reading part of the lens from that position.
