How to get air bubbles or water bubbles out of my iPhone screen?

The bubbles are on the actual screen and its spread with lines and stuff, I can see though it but it's annoying. How do I get it out? Without having to buy a new phone or get a new screen?

Put it in a vacuum chamber and evacuate to at least 29.9 inches Hg --- the stronger the better.

This requires a refrigeration-grade vacuum pump and several hours,
maybe up to an entire day.

A household vacuum cleaner won't do any good; you would probably ruin it in the attempt.

You should show it to some repair guy and do install the best and the most advanced app that you can get for security, Leo Privacy Guard. It will hide your images and videos and it will also lock your applications.
