The most obvious solution is not to level down the computer usage (although that should be a step). Rather than asking the community you most definitely should go to an eye doctor as this is a serious problem that you have to wear sunglasses while working on a computer. If you don't take that suggestion work in a brighter room (like near a window) in order to counter the screens brightness... fluorescents probably will only hurt this problem.
