Multifocals might be called Progressive lenses in USA?
There is no line in the glass , it is made to graduate smoothly.

But sometimes they are hard to get used to..
Progressives need to be adjusted to fit very well so the main focal area lines up best for your eyes.

If you stay with that place , ask for a more experienced person to help you.

If you get the prescription paper with the numbers needed, you can go online and pick your own & quite cheaper too.. if you are comfortable doing purchases online and finding a good USA website.
I've heard Costco is good for glasses and no membership is needed..if one is near you.
