What additional strategy can complement the 20-20-20 rule in managing eye health?

The correct choice, which is eye exercises, complements the 20-20-20 rule effectively because it encourages regular movement and focus changes for the eyes, helping to alleviate strain. The 20-20-20 rule itself suggests that every 20 minutes, a person should take a break and look at something 20 feet away for at least 20 seconds. By incorporating eye exercises into this routine, an individual can further strengthen eye muscles, improve flexibility, and enhance overall visual comfort.

Eye exercises, such as rolling the eyes, focusing on near and far objects, and practicing blinking can help counteract the fatigue that comes from prolonged screen time. This two-pronged approach—spacing out focus with the 20-20-20 rule and actively engaging eye muscles through exercises—creates a more holistic strategy for maintaining eye health and preventing discomfort due to digital strain.

In contrast, regular sleep is important for overall health but doesn't directly address the strain caused by screen use in the same way. Sitting closer to the screen does not help with eye health and can actually worsen strain and discomfort. Using high contrast settings may improve visibility on screens but does not directly combat eye fatigue like the combination of the 20-20-20 rule and eye exercises
