Clinical Rules for Monitor Elevation & Eye Health

1. The Top 1/3 Horizon

The top border of your display must align with or sit 1 to 2 inches below your horizontal eye line. Looking straight ahead should meet the upper portion of the screen.

2. Downward Gaze Angle

Maintain a 15° to 20° downward gaze angle. Looking slightly downward covers more of the cornea with the eyelid, significantly reducing tear evaporation and dry eye syndrome.

3. 20-20-20 Rule

Every 20 minutes, look at an object 20 feet away for 20 seconds. This releases chronic tension in the ciliary eye muscles that causes screen-induced headaches.
