I've always thought that if I can get used to progressive lenses, then ANYONE can! I say that because it doesn't take much for me to feel queasy or dizzy/disoriented. I HATE that feeling! I can't do roller coasters or any other kind of similar ride or attraction. I used to get car sick easily when I was younger, and I've never been able to read or write while riding in any kind of vehicle.
So, I was very hesitant to switch from my single lens glasses to progressives. However, it was something I really needed to do. It did take me a little while to get used to my first pair, but I've been wearing progressives for about twenty years now and love them! Funny story...well, not funny at the time...but when I got my first pair of progressive lenses, I had a horrible time! For the first day or so, everything was completely distorted. I had a terrible time judging curbs, stairs, just about everywhere I put my feet. I couldn't even read with them. Everyone told me to give it time, that I would adjust, but it was awful. Finally, I went back to the eye doctor (which was also where my glasses were made) and had them check the prescription. Yep, they were incorrectly made, and were way off!

After I got fitted with the correct lenses, it was fairly easy to get used to them!
So, if you really feel something doesn't seem right when you first get your progressives, don't hesitate to take them back and get them checked out! I also don't think it matters where you get your glasses made. That first pair (the ones made incorrectly) were from a doctor's office. I thought it would be the best place to get them done. It wasn't. Since then, I've had glasses made from different places, mostly Lenscrafters, and nobody has ever messed up the prescription!
