How to save your eyes from screens
1. Use the 20-20-20 Rule for Eye Relief
The 20-20-20 rule suggests taking a 20-second break every 20 minutes to look at something 20 feet away. This approach, backed by eye care professionals, helps relax your eye muscles and encourages natural blinking, which can ease eye strain.
To stick with this habit, consider setting reminders. For reference, 20 feet is about the distance to a window or across an average-sized room.
How to Start Using the 20-20-20 Rule
Getting started with the 20-20-20 rule is simple, especially with the help of apps designed to keep you on track. These tools send notifications to remind you when it’s time for a break:
- iPhone and Mac users: Check out apps like Eye Care 20 20 20 or Eye Monitor – Break Reminders.
- Android users: Try 20 20 20: Eye Break Reminder.
- Apple Watch users: Relax Eyes-Pro is a great option.
- Windows users: Download Twenty.
Choose an app that fits your needs, whether you prefer subtle banner alerts or full-screen notifications. Many of these apps also allow you to customize the intervals to match your work rhythm.
If you’re not a fan of apps, a simple solution is to set a recurring alarm on your phone or use a kitchen timer. While this requires manually resetting the timer after each break, it’s still an effective way to remind yourself to rest your eyes.
Start using these reminders during your work hours. Over time, you might find yourself naturally recognizing when it’s time to give your eyes a break.
2. Adjust Screen Brightness and Display Settings
Taking regular breaks is crucial, but fine-tuning your screen’s brightness and display settings can go a long way in reducing eye strain. When your screen is either too bright or too dim compared to your surroundings, your eyes have to work overtime, which leads to quicker fatigue and discomfort.
The trick is to match your screen brightness to your environment. For instance, if you’re in a well-lit office, your screen should be brighter. Conversely, in a dimly lit room, lowering the brightness helps your eyes adjust more naturally. Pairing this adjustment with regular breaks creates a solid foundation for eye comfort.
Contrast settings are equally important. Aim to keep your monitor’s contrast around 60% to 70%, adjusting it to what feels most comfortable for you. This range typically ensures a clear distinction between elements on your screen without being too harsh.
Readable text is another key factor. Choose a font size that’s easy to read from an arm’s length. For most people, increasing browser or system display settings to 125% or 150% works well. For web content, body text should be at least 16 pixels, with headings 1.5 to 2 times larger.
Color contrast also plays a big role. The Web Content Accessibility Guidelines suggest a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18 points or more). Whether it’s dark text on a light background or light text on a dark background, the goal is to make content easy to read without straining your eyes.
| Text Element | Poor Setting | Optimal Setting |
|---|---|---|
| Font Size | 12px (Too Small) | 16px+ (Comfortable Reading) |
| Line Height | 1.2x (Crowded) | 1.5x–2x (Easy Scanning) |
| Letter Spacing | 0.05em (Tight) | 0.12em–0.16em (Clear Separation) |
Turn On Night Mode and Auto-Brightness
Features like night mode and auto-brightness can make a noticeable difference, especially during evening hours or when transitioning between different lighting conditions.
Night mode reduces blue light by shifting your screen’s colors to warmer, amber tones. This is particularly helpful after sunset, as cooler blue light can feel harsh and disruptive to your eyes. Many devices automatically adjust the intensity of this feature based on local sunset and sunrise times.
Meanwhile, auto-brightness adapts your screen’s brightness to match your surroundings, sparing you from sudden and uncomfortable changes in lighting.
Together, these features help maintain consistent and comfortable viewing conditions without the need for constant manual adjustments. You can enable both options in your device’s display settings to ensure your screen is always easy on the eyes. Up next, discover how reducing blue light can further support your eye health.
3. Block Blue Light from Digital Devices
Digital screens emit blue light, which is helpful during the day but can cause trouble when overexposed in the evening. While natural blue light supports a healthy sleep-wake cycle, using devices late at night can disrupt melatonin production, making it harder to fall asleep. It can also lead to digital eye strain, with symptoms like eye fatigue, dryness, and even headaches after long periods of screen time.
Reducing blue light exposure is one way to ease these issues and improve overall eye comfort. There are two main approaches: physical screen filters and built-in software solutions.
Screen filters physically block blue light before it reaches your eyes. They’re a good choice for devices that don’t have built-in blue light reduction settings or if you want consistent protection regardless of your device’s configuration.
On the other hand, many modern devices come with built-in blue light filters. These settings adjust the screen’s color temperature, shifting it to warmer tones, which are less harsh on your eyes in the evening. Both options are worth considering as part of a broader strategy to manage digital eye strain.
Blue Light Glasses vs. Software Filters
If you’re deciding between blue light glasses and software filters, here’s how they compare:
| Feature | Blue Light Glasses | Software Filters |
|---|---|---|
| Cost | Depends on lens quality | Usually free, built into devices |
| Effectiveness | Varies by lens quality | Offers moderate reduction |
| Convenience | Wearable with any device | Automatically adjusts via settings |
| Appearance | May add a slight tint | Changes screen colors to warmer tones |
| Durability | Physical product, can wear out | No physical wear and tear |
| Customization | Fixed filtering level | Adjustable intensity and schedules |
Blue light glasses are particularly useful if you frequently switch between devices. Their effectiveness depends on the quality of the lenses, with higher-end options providing better filtration (though they might add a noticeable tint).
Software filters, however, are a more flexible and cost-effective solution. Many devices let you customize the intensity of the filter, and some even allow you to schedule it to activate automatically in the evening. This makes them perfect for everyday activities like reading, browsing, or working.
For the best results, consider combining both methods. Use software filters as your go-to solution and add blue light glasses for extra protection during long screen sessions or late-night device use.

4. Set Up Proper Posture and Workspace
How you arrange your workspace can make a big difference in avoiding digital eye strain and physical discomfort. A poorly positioned monitor can lead to neck, shoulder, and eye strain, making long hours in front of a screen even more taxing.
To start, make sure your screen is at a distance where you can read comfortably without squinting or leaning forward. Ideally, the top of your monitor should align with or sit just below your eye level. Tilting the screen about 15° below horizontal helps create a natural, 30° viewing range that feels easier on your eyes.
Taking the time to arrange your workspace thoughtfully works hand-in-hand with other strategies to minimize digital eye strain. Small adjustments like these can go a long way in keeping you comfortable.
5. Get Regular Eye Exams
Taking care of your eyes goes beyond quick fixes – regular eye exams are key to maintaining long-term vision health. Many people don’t realize they need vision correction until an exam uncovers an issue. In fact, around 11 million Americans over the age of 12 require some form of vision correction.
A thorough eye exam does more than just determine if you need glasses. It can detect early signs of digital eye strain, uncover related conditions, and offer personalized recommendations to improve both your lifestyle and screen habits. Since some eye problems develop silently, without noticeable symptoms, routine checkups are essential for protecting your vision.
How often should you schedule an eye exam? That depends on your age and overall risk factors. Here’s a general guideline:
- Adults under 40 with no known vision issues should aim for an exam every two years.
- Between 40 and 60, a checkup every one to two years is often recommended.
- Over 60? Annual exams are the way to go.
If you wear corrective lenses, experience frequent headaches, have a family history of eye diseases, or live with conditions like diabetes or high blood pressure, you may need more frequent visits. And if you notice sudden changes like blurry vision or sensitivity to light, don’t wait – schedule an appointment right away. Regular exams are an essential part of keeping your eyes healthy, alongside your daily care routine.
