When Your Eyes Feel Tired, Try the 20-20-20 Rule

When your eyes feel tired, try the 20-20-20 rule. Staring at a computer or phone for long periods can easily cause dry eyes, fatigue, and blurred vision. This doesn't necessarily mean your eyesight has worsened; it could be due to your eyes focusing on near objects for extended periods, coupled with reduced blinking. There's a simple method called the '20-20-20 rule': Every 20 minutes of screen time, look at something about 20 feet, or 6 meters, away for 20 seconds. This allows your eyes to temporarily shift away from the near-focus state, helping to alleviate some visual fatigue. Another easily overlooked detail is blinking. When concentrating on a screen, people tend to blink less unconsciously, causing tears to evaporate faster and leading to dryness. You can remind yourself to blink naturally, place your screen at a comfortable distance, and avoid environments that are too dry or have air conditioning blowing directly into your eyes. If your eyes are frequently dry, consider using preservative-free artificial tears. If you experience persistent pain, noticeable photophobia, or sudden changes in vision, seek medical attention promptly. Eye care doesn't always require expensive products. Regular breaks, natural blinking, and adjusting your screen distance are small habits you can start implementing daily.
