I wear gamma ray glasses when around screens, in a very light room or outside. They are blue light blocking and UV blocking. I'd recommend installing f.lux as well (just google this). It dims the computer and reduces blue light according, following the sun, or you can manually make it darker like night. Hitting Ctrl + Alt + Print Screen gives you high contrast options. If you use google chrome while using this, it can give you extensions( options) for high contrast and darker themes.

Hope this helps!
