You can. You can literally go into places and say "here's my prescription, I want a pair of glasses.". They will actually do this.

This.

Also, in a lot of places, you can even just hand them your old glasses, and they can basically scan them to see what the prescription is for them, and then just duplicate it.

But it's also worth noting that you probably shouldn't do this, even if you think your prescription hasn't changed, because it may have. And you should get checked to make sure you have the best possible prescription because otherwise you can strain your eyes.

I actually had a situation where my old pair of glasses had shifted so they didn't sit on my face right, and my prescription apparently shifted to match as my eyes got used to the new positioning. But then when I went and got new glasses, I just used my old prescription. And then I wound up having weird motion sickness issues and trouble focusing, which turned out to be because my prescription wasn't actually the same, and it became a problem when the new glasses sat on my nose differently and the angle wasn't quite right.

I wouldn't say you need to get your eyes checked every new for new glasses (though once you get older you might want to get checked at LEAST once a year for cataracts and glaucoma, or things like detached retina or other issues), but if you're going to get new glasses, you definitely should get your eyes checked to get a new, accurate prescription for them.
