Here is a good rule of thumb for any visually-dependent activity (computer, crafts, handwork, etc) —
the “20-20 rule“:
For every 20 minutes on the computer (or other visual demand), look at something 20 feet away for 20 seconds.
Use this pause to:
- Give your eyes a break from visual strain
- Take a deep breath and release tension
- Bring awareness to and reset your posture
- Connect with your feet and sit bones
