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 reduces eye strain by allowing your eye muscles to relax from close focus work.
How far should a computer screen be from your eyes?
Your monitor should be 20 to 26 inches from your eyes, with the top of the screen at or slightly below eye level to reduce neck and eye strain.
