A couple of months ago I upgraded to Office 2013 at work. I liked it, but around the same time, my eyes started burning. I never made the connection, but then last week, when a coworker upgraded, he mentioned his eyes were burning, and he made the connection.
He found this guide for toning down Office. We both recommend the dark gray scheme, which is much easier on the eyes than the default harsh white scheme.
