Air bubbles under my otterbox screen protector?

A little question about the otterbox. So I got an iPhone 5 a couple weeks back and bought an Otterbox to go with it, and noticed this weird screen distortion caused by air getting trapped underneath the screen. It almost looks like water is in between the screen and the screen protector, but it's apparently just air. I tried taking the screen off and putting it back on, and they went away temporarily but would only ease their way back in whenever I started using the screen again. It's no big deal, but it's just annoying to look at and makes my phone looks less attractive. How can I fix this?

Don't use a screen protector I don't think they are useful and they always make your phones screen look bad
