Taking short breaks from looking at a screen every 20 minutes can reduce eye strain symptoms, according to research.
The 20-20-20 rule suggests that people should look out a window during the 20-second breaks, download an app to help follow the rule, and remember to blink.
Additionally, symptoms can occur after watching television at a close distance, reading, doing computer work, or performing any close activities that use the eyes.
This suggests that the distance from a screen can affect the effect of eye strain.
