Question

Eyeball experts suggest you look away from your screen every 20 minutes

Answer 1

Answer:

Explanation:

→ Staring at a screen continuously for hours on end causes focusing fatigue. To avoid this, many eye experts recommend the “20-20-20 rule” – looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20ft away for at least 20 seconds. The science behind this trick is that looking at objects at a distance relaxes the focusing muscle in the eye, helping to reduce fatigue.
