After a particularly intense few weeks of work of computer-based work, I started getting double vision every time I tried to read or type at a computer screen. Initially it was rather disturbing. Recovery was 3 days away from screen time and time outdoors (focusing eyes on far away things). I've definitely reformed my habits to spend time looking out the window more. Also, flux is a requirement for any screen I use.
