I had progressive lenses for years... I do remember the first few months... Whenever I looked quickly to one side, it was like the whole room was moving... Walking down steps was even worse... I got used to them, but now my 'long' sight has improved so much, I no longer need glasses to drive or other everyday chores, and I now have just reading glasses. I have been wearing glasses since I was 11 years old (I should have had them at 7, but they were a bit behind in those days)
At 11 I again asked my Mum to take me to the optometrist... I had tried a pair of glasses from a friend in school, and I could suddenly see the leaves on the trees, and even the clock on the wall (and what time it was)
