— Explanation · 中文詳解 —
定時從螢幕時間中休息（例如 20-20-20 法則：每 20 分鐘看 20 英尺遠的物體 20 秒），是減緩眼睛疲勞最有效的方法。昏暗光線閱讀會加劇疲勞；常規使用眼藥水可能掩蓋問題；室內戴太陽眼鏡不必要。
Taking scheduled breaks from screen time (for example, the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds) is the most effective way to reduce eye strain. Reading in dim light worsens fatigue; routine use of eye drops may mask underlying problems; and wearing sunglasses indoors is unnecessary.
