Frequently asked questions
How much screen time is too much?
There's no single limit for adults, but long unbroken stretches strain your eyes and posture. The bigger issue is what screen time replaces — sleep, movement and in-person time.
What is the 20-20-20 rule?
Every 20 minutes, look at something 20 feet (6 m) away for 20 seconds. It relaxes the eye muscles and helps reduce digital eye strain.
How can I reduce eye strain from screens?
Follow the 20-20-20 rule, blink often, keep the screen an arm's length away and slightly below eye level, and reduce glare and brightness in the evening.
Does screen time before bed affect sleep?
Yes. Bright and blue-rich light in the evening can delay sleep and reduce its quality. Dimming screens or stopping an hour before bed helps.
