I just remembered hearing about this sometime last year, and I thought I’d pass it on. Basically: Every 20 minutes, pause whatever you’re doing and stare at something 20 feet away for 20 seconds. This gives your eyes a chance to relax, and has been shown to prevent many vision problems resulting from long hours of computer work. And we do excel at the long hours of computer work, here at Needmore.
Be sure to take the time to set up your display correctly, as well.
