I know it's not the same but for those that won't do this (for such a long period) at least activate/install some kind of night mode. It automatically adjusts the warmth of your screen color depending on time/daylight.

In the evening (or early morning) it will transition the colors to a warmer (red) tone. This helped me a lot. I really tire easier while sitting in front of the screen.

E.g. Gnome has this out of the box. It's called "night light".
