I've been wearing glasses since I was 14, bifocals/progressives since I was about mid-thirties. Every pair of glasses I've owned has required something of a "learning curve". I have never put on a pair and said, "Wonderful!" Back when I wore plain glasses, that learning curve was short: Say, a couple days. My first pair of progressives, however, took me the better part of a year to learn to love -- but learn I did.
Hints:
When I got my first pair, the opthomatrist said, "With these glasses, you can see whatever your nose points towards." I didn't really understand at that point, but I do now. With progressives, you must turn your head to see what you want to look at. You don't get any real "side vision" with progressives. This was very difficult for me, but now it's second nature.
Working at the computer is difficult with progressives. The "reading portion" of the lenses is at the bottom, and you have to tilt your head up at an unnatural angle to read the words on the screen. The answer is to keep a pair of cheap readers at the computer. Do you know what your lens prescription is? Mine's +2. You can get that very same +2 in a reader. I also keep a pair next to my bed because I prefer reading with a pair of readers instead of my prescription glasses (because the prescription glasses have only a little slice of reading-glass at the bottom of the lens). The progressive lenses are best for walking-around all day, but for these circumstances, they're not best.
Oddly enough, stairs have never bothered me, whereas I've heard other people say that was the worst for them.
I have prescription sunglasses that're "distance only" for driving, and I love those things, but when I get another pair I'll add in the progressive lens. I hate not having the ability to read something while wearing them.
In closing, I think everyone has some trouble adjusting to these glasses. When I got my last pair, a man was in the office CHEWING OUT the girl who had sold him a pair of glasses a few weeks before. I know what he was going through, but he didn't have to be nasty to her about it. What he really wanted was to have his young, adjustable eyes that could be "fixed" with a simple prescription. I'd like to have that too, but since it's not going to happen, progressive lenses are the best I'm going to get.
