We live in a digital world so screen time is unavoidable. Whether for work, study, or leisure, prolonged exposure to screens can cause digital eye strain, leading to blurry vision, dry eyes, and headaches. If you frequently experience blurry vision after staring at a screen, here are some practical ways to prevent and reduce the effects:
- Follow the 20-20-20 rule
One of the simplest ways to reduce eye strain is by following the 20-20-20 rule. Every 20 minutes, take a 20-second break and look at something 20 feet away. This allows your eyes to relax and prevents them from becoming overly fatigued.
- Adjust screen settings
- Brightness: Ensure your screen brightness matches the ambient light in your surroundings. A screen that is too bright or too dim can strain your eyes.
- Contrast and Text size: Increase contrast and use larger text to reduce the effort needed to read.
- Blue light filter: Enable night mode or use blue light filtering software to reduce exposure to high-energy blue light, which contributes to digital eye strain.
- Maintain proper screen distance and Posture
Your screen should be at least an arm’s length away (about 50-70 cm) and positioned slightly below eye level. Sitting too close or too far from the screen can make your eyes work harder than necessary, leading to fatigue and blurry vision.
- Blink more and Stay hydrated
When using screens, people tend to blink less frequently, leading to dry eyes. Make a conscious effort to blink more often or use lubricating eye drops to keep your eyes moist. Staying hydrated also helps prevent dryness and irritation.
- Take frequent breaks
Apart from the 20-20-20 rule, give your eyes a longer break every two hours. Step away from the screen, go for a short walk, or do an activity that does not involve digital devices.
- Reduce glare and Improve lighting
Glare from overhead lights or windows can strain your eyes. To reduce glare:
Use anti-glare screen protectors
- Adjust your desk lamp or room lighting
- Position your screen away from direct sunlight
- Eat a vision-friendly diet
Certain nutrients support eye health and help prevent vision problems:
- Omega-3 fatty acids (found in salmon, walnuts, and flaxseeds) prevent dry eyes.
- Vitamin A (found in carrots and leafy greens) supports overall eye health.
- Lutein and Zeaxanthin (found in eggs and spinach) help protect against blue light damage.
- Consider blue light glasses
If you spend long hours on screens, consider wearing blue light blocking glasses to reduce exposure to harmful blue light, which contributes to digital eye strain and disrupted sleep patterns.
- Get regular eye check-ups
If you experience persistent blurry vision, headaches, or discomfort despite taking precautions, consult an optometrist. Regular eye exams can help detect underlying issues and ensure you have the correct prescription if needed.
