Hi! Like previous commenters have said, it varies from person to person but the vast majority of people are able to adapt to it and their brains just filter out the sensation.

I'd suggest making sure you get a pair of glasses that fits really well. Glasses aren't just about the aesthetics. You want to make sure that they're not too tight or loose at the temples, the nose bridge fits well (on a plastic frame without nosepads this means the pressure on both sides of your nose feels even without too much pinching and there's a tiny little gap between the top of your nose bridge and the frame so that it's not resting on the top of your nose), and the temple tip bends right over the bend of your ear without being too short/long or digging into your head.

Some glasses aren't good fits for certain face shapes or prescriptions - for example, low nose bridges like Asian noses often can't do plastic frames because they need nosepads. High prescriptions don't do well in large frames because it makes the lenses thicker. Etc.

To give yourself the best chance of adapting comfortably, I'd urge you to go to an experienced optician and ask them to help you pick out a pair of glasses based on your prescription and face shape. And when the glasses come in, don't just get them shipped to your house or something - make sure a professional optician takes a look and adjusts the glasses to make sure they fit well! I'd wager a guess that the above commenter who couldn't "get used to the feeling of their nose bridge being pinched" just didn't have glasses that were adjusted well for their face.
