Frequently Asked Questions

What is the 20-20-20 rule?

Every 20 minutes, look at something 20 feet away for at least 20 seconds. This relaxes the focusing muscles in your eyes and helps prevent digital eye strain and fatigue.

How far should my screen be from my eyes?

Your computer screen should be 20 to 26 inches (50 to 66 cm) from your eyes. For phones, 12 to 16 inches is recommended. The farther the screen, the less strain on your focusing muscles.

How often should I take breaks from sitting?

Experts recommend standing or moving for at least 5 minutes every 30 to 60 minutes. If you sit more than 8 hours daily, aim for breaks every 30 minutes to reduce back and neck strain.

What is proper screen height for ergonomics?

The top of your monitor should be at or slightly below eye level, about 20-26 inches from your face. The screen should be tilted slightly back (10-20 degrees) so you look slightly downward.
