“The best, most immediate solution for eye strain is much simpler: Make sure you look away from the computer from time to time. Dr. Kramer [director of comprehensive ophthalmology at the Emory Eye Center in Atlanta] cites a ’20-20-20’ rule: Look away from the computer screen every 20 minutes and focus on an object 20 feet away for 20 seconds.”
