It's actually not going to solve the problem, just to look up from your computer screen. You need to go to a window. You need to look out at a distance. Ideally, you would even open the window, because those windows actually filter out a lot of the blue light that you want during the daytime. A lot of the sunlight, it's actually 50 times less gets through. You want to get out onto a balcony. You want to relax your eyes and look out at the horizon.
