Before actually spending any money, I'd recommend flux if you don't already have it. It slightly tints the screen so that it isn't as bad on your eyes. The amount it tints is based on the time of day, so its darker at night. My eyes have been feeling a lot less strained since I've started using it.

Yes I recommend me too, very handsome so will distract you from staring at screens; stare at me instead
