Frequently Asked Questions (FAQ)
What is the 20-20-20 rule for eye health?
The 20-20-20 rule suggests taking a 20-second break every 20 minutes to look at something 20 feet away. This helps reduce eye strain by giving your eyes a chance to refocus and relax.
How does blue light affect sleep?
Blue light from screens can suppress the production of melatonin, a hormone that regulates sleep. Exposure to blue light in the evening can make it harder to fall asleep and reduce sleep quality.
What are the symptoms of digital eye strain?
Common symptoms include dry eyes, eye fatigue, blurred vision, headaches, neck and shoulder pain, and difficulty focusing. These symptoms typically improve when you take breaks from screen use.
How much screen time is considered healthy?
There's no one-size-fits-all answer, but generally, limiting total screen time to under 8 hours per day and taking regular breaks is recommended. The key is balance and ensuring screen time doesn't interfere with sleep, physical activity, or social interactions.
Can screen time cause permanent eye damage?
While screen time can cause temporary discomfort and eye strain, there's limited evidence that it causes permanent eye damage. However, it's important to practice good eye health habits and have regular eye exams.

Did you know that...?
The Screen Time Revolution: From "TV Rot" to Digital Wellness Science
The concept of measuring screen time impact was revolutionized in the 2010s when Dr. Jean Twenge at San Diego State University conducted the largest study ever on digital device usage, analyzing data from over 1 million teenagers. This groundbreaking research revealed that the relationship between screen time and health was not linear but followed a "Goldilocks" curve - some screen time was beneficial, but too much was harmful. The study showed that 1-2 hours of recreational screen time per day was optimal for mental health, while more than 3 hours significantly increased depression and anxiety risk.
What makes this discovery particularly fascinating is how it changed the entire approach to digital wellness. The research revealed that the type of screen time mattered more than the duration - educational content and video calls with friends had positive effects, while social media scrolling and passive entertainment had negative effects. This led to the development of the first evidence-based screen time guidelines and the realization that quality screen time could enhance learning and social connection. Today's screen time calculators are based on over 10 years of research involving millions of users across all age groups and device types.
💡 Fun Fact: Dr. Twenge's research was so influential that it's now used by the American Academy of Pediatrics and is the foundation for all modern screen time recommendations!
