How to deal with pain in eyes and headaches?

Hello cscareerquestions! I started my first full time dev job in July. In the past couple weeks I've started having regular dull pain kind of in and behind my eyes and headaches all the time. I think it's from the amount of time I spend looking at a computer screen! Not only do I spend all day at work staring at my computer, but I also play video games/watch netflix etc in my spare time (It's bad to spend that much time with screens, i know...)

I'm wondering if other people experience this too and how you might deal with it? I feel like I'm going to permanently damage my eyes if I continue... any advice?
