How to Prevent Eye Damage from Phones: 12 Best Practices
Phones have become an essential part of daily life. However, prolonged screen use can strain the eyes and lead to discomfort. Adopting practical habits and making simple adjustments can protect your eyes and maintain healthy vision. This post will discuss 12 effective practices to minimise eye damage from phone use.
What Happens to Your Eyes During Prolonged Phone Usage?
Prolonged phone use can have real effects on your eye condition. From the straining blue light emitted by screens to reduced blinking, your eyes constantly work overtime. Knowing these effects can help you take better care of your eyes while using your phone and reduce digital eye strain.
Blue Light Exposure and Its Effects on the Retina
Your phone emits blue light, which penetrates deep into your eyes. Over time, excessive exposure may lead to retinal damage and increase the risk of macular degeneration.Increased Risk of Digital Eye Strain
Staring at your digital screen for long periods can lead to symptoms like blurred vision, headaches, and difficulty focusing. This is often called digital eye strain or computer vision syndrome.Dryness Due to Reduced Blinking Rates
When you're focused on your phone, your blinking rate drops significantly. This reduces tear production, leading to dry, irritated eyes that may feel gritty or uncomfortable.
Symptoms of Digital Eye Strain
Digital eye strain, or called computer vision syndrome, is a common eye condition caused by the extended use of digital devices and gadgets such as computers, smartphones, and tablets. It appears through various symptoms that can impact daily life and productivity. Below is a table summarising the most common symptoms, their descriptions, and how frequently they are reported among users.
| Symptoms | Description | Frequency Among Users |
|---|---|---|
| Blurry Vision | Difficulty focusing on the screen, leading to unclear sight. | High (60-70%) |
| Dry Eyes | Insufficient moisture in the eyes due to reduced blinking. | High (50-60%) |
| Headaches | Pain or pressure around the eyes, forehead, or temples. | High (40-50%) |
| Eye Fatigue | Tired or sore eyes after prolonged screen use. | High (70-80%) |
| Neck and Shoulder Pain | Discomfort due to poor posture or prolonged sitting. | Moderate (30-40%) |
| Increased Light Sensitivity | Difficulty in tolerating glaring lights after screen exposure. | Moderate (20-30%) |
| Difficulty Focusing | Challenges in shifting focus between near and far objects. | Moderate (30-40%) |
12 Best Practices to Prevent Eye Damage
Protecting your eyes from strain and long-term damage is essential, especially in today's digital age. Incorporating simple, proactive habits into your daily routine can help improve eye health and reduce the risk of digital eye strain, dryness, and fatigue.
Here are 12 best practices to help maintain your vision and overall eye wellness.
1. Enable Blue Light Filters
Activating blue light filters, such as in computer screens, can reduce eye strain caused by prolonged use. Most modern devices have built-in night mode or blue light filter settings that adjust the screen's colour temperature, making it warmer and easier on the eyes. Without this feature, computer users can use third-party apps to achieve similar benefits for older phones or devices. These adjustments help minimise exposure to harmful blue light, particularly during evening hours.
2. Adjust Screen Brightness and Contrast
Properly adjusting the brightness of your computer screen and contrast to match your environment is crucial for reducing eye tiredness. Brightness that is too high or too low can force your eyes to work harder, leading to discomfort over time. Aim to keep your gadget and computer screen brightness to match the surrounding light for clear, sharp text.
BRIGHTNESS LEVELS VS. EYE STRAIN LEVELS
| Brightness Level | Eye Strain Level | Description |
|---|---|---|
| Low | High | Screen appears too dim, requiring more effort to read or focus. |
| Medium | Low (Optimal Level) | Balanced brightness reduces strain and matches ambient lighting. |
| High | Moderate to High | Excessive brightness causes glare and discomfort over time. |
3. Use Larger Fonts
Increasing font size on your devices enhances readability, reducing the need to squint or strain your eyes. Larger fonts make processing text quickly and comfortably easier, especially during prolonged gadget and computer screen use. Adjust font sizes in your device settings or applications to suit your visual comfort and prevent unnecessary eye strain.
4. The 20-20-20 Rule
The 20-20-20 rule is a simple yet effective strategy to help reduce screen time and even headaches. This practice is one effective way how to protect the eyes from computer screens. Every 20 minutes, take a break from the computer monitor or device and focus on something at least 20 feet away for 20 seconds. This practice helps relax and protect your eyes, reduces fatigue, and prevents prolonged screen time from overwhelming your vision.
5. Reduce Screen Time
Limiting time for usage is crucial for maintaining eye health and preventing blurred vision, especially for those who spend extended hours on digital devices. Balancing screen use with offline activities can help reduce eye fatigue and improve overall well-being.
RECOMMENDED SCREEN TIME BY AGE GROUP
| Age Group | Recommended Screen Time | Suggested Activities |
|---|---|---|
| Children (6-12) | 1-2 hours/day | Outdoor play, reading physical books, board games. |
| Teens (13-18) | 2-3 hours/day | Sports, creative arts, socialising offline. |
| Adults (19-60) | Limit recreational gadget use to 2 hours/day | Exercise, cooking, journaling, engaging in hobbies. |
| Seniors (60+) | Minimal recreational gadget use | Walking, gardening, solving puzzles. |
Tips for Reducing Screen Time:
Set screen-free zones, like during meals or before bedtime.
Use apps or timers to track and limit usage.
Engage in offline hobbies such as painting, knitting, or hiking to stay productive while reducing screen dependency.
6. Maintain Proper Viewing Distance
Keeping an appropriate distance from your gadgets and computer screens is essential to protect your eyes, minimise eye fatigue, and prevent blurred vision. Adjust viewing distance to 20-24 inches from your eyes to the screen, with the top of the screen at or slightly below eye level.
VIEWING DISTANCE VS. EYE STRAIN LEVELS
| Viewing Distance | Eye Strain Level | Description |
|---|---|---|
| < 18 inches | High | Too close, causing excessive focus and muscle strain. |
| 20-24 inches | Low (Optimal) | Ideal distance for reduced strain and improved comfort. |
| > 30 inches | Moderate | Screen may appear too small, requiring more effort to read. |
7. Blink Frequently
Blinking is a natural way to keep your eyes moist and reduce dryness, especially during prolonged screen use. When we focus on screens for long periods, we tend to blink less often and stare more, leading to discomfort and digital eye tiredness.
Blinking Exercises to Maintain Eye Moisture:
Conscious Blinking: Every 20 minutes, close your eyes slowly for 2-3 seconds, then reopen them. Repeat 5-10 times.
Blink Breaks: During breaks, relax your eyes intentionally and spend time frequently refreshing your eyes. You can also reduce gadget usage an hour before you sleep.
Palming Exercise: Rub your hands together to generate warmth, place them over your closed eyes for 10 seconds, and blink a few times when done.
Eye exercises help relieve eye fatigue, reduce muscle tension, improve flexibility and focus, and enhance blood circulation around the eyes. These quick and easy practices maintain eye health, especially during prolonged screen use.
8. Adjust Ambient Lighting
Ambient lighting in front of a computer and phone helps minimise screen glare, eye problems and reflections, which can tire our eyes and make screen content harder to view. Harsh lighting, either too bright or too dim, creates contrast issues that force your eyes to work harder.
Tips for Setting Up Appropriate Lighting:
Reduce Glare: Use curtains or blinds to block direct sunlight, and position your screen to avoid reflections and neck pain.
Balance Light Levels: Combine natural and artificial lighting to create a comfortable workspace.
Use Desk Lamps: Opt for adjustable lamps with soft, warm, fluorescent lighting in front of a computer for focused tasks.
Avoid Overhead Glare: Replace glaring overhead lights with diffused ones to reduce strain.
