Tips To Prevent Digital Eye Strain
Follow the 20-20-20 Rule
The 20-20-20 rule, supported by the American Optometric Association and the American Academy of Ophthalmology, is a simple method to reduce digital eye strain. A study in Malaysia involving 795 students revealed that nearly 90% experienced eye strain symptoms after just two hours of computer use.
What Is the 20-20-20 Rule?
The rule is easy to follow: every 20 minutes of screen time, take a 20-second break to focus on something about 20 feet away. This helps counteract the reduced blink rate caused by staring at digital screens, which often leads to dryness and discomfort.
Tips for Making It Part of Your Routine
Here are some practical ways to stick to the 20-20-20 rule:
- Use Digital Tools:
Apps and extensions like Eye Care 20 20 20 (iOS), 20 20 20: Eye Break Reminder (Android), and 20/20/20 Reminders (Chrome Extension) can help you stay on track. - Set Up Visual Cues:
Position your desk to face a window or a distant wall. Identify an object about 20 feet away to focus on during breaks. Sticky notes on your monitor can also serve as handy reminders. - Make the Most of Breaks:
Use these moments to do slow, complete blinks to rehydrate your eyes. Stand up, stretch, and drink some water to refresh your body.
According to The Vision Council, 59% of people using digital devices report symptoms of eye strain. Pairing the 20-20-20 rule with other workspace adjustments can help keep your eyes comfortable and healthy.
Set Up Your Workspace Correctly
Taking regular breaks can help with eye fatigue, but setting up your workspace properly is just as important. A well-arranged workspace can reduce eyestrain, neck pain, and posture-related discomfort.
Monitor Position
Place your monitor 18–28 inches (45–71 cm) away from your face. The top of the screen should be at or slightly below eye level and tilted downward at a 0–30° angle.
“When sitting in front of the computer screen, simply place the monitor at the exact length equal to that of your fully extended arm.” – ViewSonic Library
For more precise adjustments, consider using a full-motion monitor mount. If you wear glasses, it’s best to position the monitor a little below eye level.
Control Light and Glare
To reduce glare, position your screen at a 90° angle to windows. Use blinds or shades, install light fixtures with diffusers, and aim for indirect lighting.
Overly bright or harsh lighting can lead to visual discomfort and fatigue. Keep your workspace evenly lit and clean your screens and light fixtures regularly to maintain a comfortable environment.
Proper Desk Setup
Good lighting paired with an ergonomic desk setup can make a big difference in visual comfort.
“When you are seated comfortably, a user’s eyes should be in line with a point on the screen about 2-3″ below the top of the monitor casing (not the screen)”.
Sit with your back straight, shoulders relaxed, feet flat on the floor, and knees bent at a 90° angle. Your hips should align with your chair, and your keyboard should be positioned so your elbows are slightly above a 90° angle.
If the recommended viewing distance feels too far, increase the font size on your screen instead of moving closer. This helps maintain proper posture and ergonomics.
Change Your Screen Settings
Optimizing your screen settings is just as important as setting up an ergonomic workspace. These adjustments can help protect your eyes and reduce strain.
Set the Right Brightness
Your screen’s brightness should match your surroundings. A simple trick: hold a white piece of paper next to your screen and adjust the display until it resembles the paper under your room’s lighting. For typical office lighting (300–500 lux), aim for a brightness level of 100–150 cd/m².
“Adjust the brightness of your monitor so it’s approximately the same as your surrounding workspace. This balance helps prevent eye strain caused by a high contrast in light.” – Zenni Optical
Once the brightness is set, take steps to minimize blue light exposure.
Reduce Blue Light
Blue light from screens can lead to eye strain and disrupt your sleep. With 80% of American adults spending over two hours daily on digital devices, it’s no wonder 59% report symptoms of digital eye strain.
You can reduce blue light on most devices by enabling specific settings:
| Device | Setting Name | Location |
|---|---|---|
| Windows | Night Light | Settings > System > Display |
| macOS | Night Shift | System Settings > Displays |
| iOS | Night Shift | Settings > Display & Brightness |
| Android | Night Light/Eye Comfort Shield | Settings > Display |
Many modern monitors also have built-in blue light filters, often listed as “Low Blue Light mode” or “Eye Saver mode” in their menus.
After reducing blue light, make sure your text is easy to read.
Adjust Text Size
Studies recommend using a 14-point font for comfortable reading on screens. For those with 20/20 vision, text should have an x-height of at least 4.5 points when viewed from 16 inches away.
If you find yourself squinting or leaning forward, it’s time to adjust:
- Windows users: Go to Start > Settings > Accessibility > Text size.
- Use clear fonts like Courier New or Verdana for extended reading.
- Adjust display scaling if necessary.
For older users or those with less flexible eyesight, larger font sizes – up to 20 points – may be needed.

Blink Often and Drink Water
Blinking Basics
Did you know that staring at screens can reduce your blinking rate by up to 60%? On average, adults spend over 13 hours a day using digital devices. Blinking is essential for keeping your eyes moist and your vision clear.
Tips to Blink More
Using a computer for long periods can lead to less blinking, but simple exercises can help:
| Time Interval | Blinking Exercise | Purpose |
|---|---|---|
| Every 20 minutes | CLOSE-PAUSE-PAUSE-OPEN-RELAX | Restore basic eye moisture |
| During screen breaks | CLOSE-PAUSE-PAUSE-SQUEEZE-OPEN-RELAX | Stimulate oil gland production |
| While waiting | Count “1,2,3,4, blink” repeatedly | Keep a consistent blinking rhythm |
If you need reminders, tools like the Eyeleo app for Windows or the Donald Korb Blink Training app for iPhone can help. Combine these exercises with proper hydration for even better results.
Stay Hydrated
Hydration is just as important for your eyes as it is for the rest of your body. Tears are made up of three layers – oil, water, and mucus – and staying hydrated helps maintain this balance.
Here’s how to keep your eyes hydrated:
- Drink 8–10 glasses of water every day.
- Eat foods high in water content, like watermelon, cucumbers, and oranges.
- Check your hydration by ensuring your urine is light and clear.
- Cut back on drinks that dehydrate, such as coffee and alcohol.
“Staying properly hydrated helps prevent dry eyes, supports tear production, and ensures the overall well-being of your eyes.”
Wear the Right Glasses
After adjusting your screen settings and workspace setup, choosing the right glasses can provide extra protection for your eyes.
Computer Glasses
Computer glasses are specially made for viewing screens at about two feet away, helping to reduce digital eye strain – a condition that affects nearly 70% of U.S. adults.
Here’s how they differ from regular reading glasses:
| Feature | Computer Glasses | Regular Reading Glasses |
|---|---|---|
| Magnification | About half-strength | Full-strength |
| Viewing Distance | Best for intermediate distances (around 2 feet) | Designed for close-up reading |
| Features | Includes blue light filtering and anti-glare coating | Basic magnification only |
| Use | Ideal for screen viewing and reducing eye strain | Meant for reading printed text |
To get the most out of your computer glasses:
- Measure the distance between your eyes and your screen.
- Consider the lighting in your workspace.
- Share your screen usage habits with your eye care provider.
In addition to custom lenses, coatings can further help reduce eye strain.
Anti-Glare Protection
Anti-reflective (AR) coatings, often paired with computer glasses, make screen time more comfortable. These coatings let nearly all light pass through the lenses, cutting down glare and improving clarity.
“Anti-glare lenses virtually eliminate glare by allowing more light and less artificial feedback directly into your eye from a single angle. This helps optimize our visual acuity, which means we can see more clearly and with less stress on the ciliary muscles.” – Felix Gray
When choosing computer glasses with anti-glare features, look for:
- Lenses that filter blue light across the full spectrum (400nm–500nm).
- About 50% blue light filtration at 450nm, where LED screens emit the most.
- A high-quality AR coating, especially if you have a strong prescription.
With 50% to 90% of computer users experiencing symptoms of computer vision syndrome, investing in the right glasses is essential. Prescription computer glasses often provide better results than basic over-the-counter blue light glasses.
Schedule Eye Care
Once you’ve adjusted your environment, it’s time to focus on regular eye care. This is crucial for protecting your vision, especially if you spend long hours in front of a screen.
Regular Eye Exams
Eye exams are key to spotting early signs of digital eye strain and other related conditions. They can also reveal issues like dry eye syndrome or binocular vision dysfunction that may be aggravated by extended screen use.
Here’s a quick guide on when to schedule your exams:
| Eye Health Status | Recommended Frequency | Additional Notes |
|---|---|---|
| Adults (18-64) | Every 1-2 years | More often if you notice vision changes |
| Contact Lens Wearers | Annually | Includes a contact lens evaluation |
| Heavy Screen Users (8+ hours daily) | Every year | Focus on symptoms of digital eye strain |
| Existing Vision Problems | Every 6-12 months | Follow your eye doctor’s advice |
“Regular eye exams go beyond ensuring your prescription glasses or contact lenses are up-to-date. They help eye doctors detect common eye problems or more intricate diseases or issues that you might not even realize you have, simply because many of them begin without any obvious symptoms.” – 20/20 Eyeglass Superstore
Take Work Breaks
Along with regular check-ups, taking breaks during work can help protect your eyes from strain caused by screen time. It’s worth noting that uncorrected vision problems cost the global economy $272 billion annually.
Here are some break tips to reduce eye strain:
- Every 20 minutes: Look at something 20 feet away for 20 seconds.
- After 2 hours: Take a 15-minute break to rest your eyes.
- During breaks: Stretch your body to improve blood flow.
“Resting your eyes allows your mind to recharge, improving concentration and efficiency when you return to work.” – Mahaveer Super Speciality Eye Hospital
During these breaks, try activities that don’t require close-up focus. This gives your eye muscles a chance to relax.
Take Care of Your Eyes While Using Screens
With Americans spending an average of 11 hours a day staring at screens, taking steps to protect your eyes is more important than ever. Studies show that over 60% of adults who spend hours in front of digital screens deal with symptoms of eye strain.
The good news? Digital eye strain is temporary and can be addressed. Dr. Jennifer Tam explains:
“While these symptoms cause discomfort, the good news is digital eye strain is temporary and will resolve with time. Many people feel better after adjusting their screen habits.”
This highlights the importance of adopting practical strategies to protect your vision.
By following simple practices like the 20-20-20 rule, setting up your workstation thoughtfully, adjusting screen settings, staying hydrated, using proper eyewear, and scheduling routine eye exams, you can manage and even prevent digital eye strain. Research shows that up to half of vision problems can be avoided with the right precautions.
As Dr. Tam advises:
“The key to working from home is balance. Make sure you take those breaks and set up your workstation appropriately to let you work smarter and not harder. If you need some guidance or have any digital eye strain symptoms, seek an eye care provider to help you address these concerns.”
