I just got progressives. I didn't have a lot of trouble adjusting to them, a friend of mine gave me really good advice. If you get used to turning your head when you need to look at something, rather than just moving your eyes, it's easier to adjust to them.
A couple of points. The prescription portion is in the centre of the lenses, so your periferal vision isn't corrected. You basically have a smaller field of vision. And, as with regular bifocals, you have to tip your head up to read stuff that isn't in exactly the right place in front of you.
I like the progressive part, no matter what you are looking at, there is a portion of the lens that corrects for that distance.
Now, I play music and spend a lot of time on the computer, so in addition to the progressives, I also got a pair of "computer" glasses. They are good enough for reading, but specifically presecribed to correct for vision at the distance from the computer screen or the music stand. I am lucky, in my home town there is a place that sells three pair of glasses for the price of 1. So I paid for the progressives (which were expensive), and then didn't have to pay extra for the computer glasses, or for prescription sunglasses for driving.
If the progressives were the only pair of glasses that I own, they would not be suitable.
