Its back to school time! That mean kids are moving up a grade level and along with that comes more reading, homework, and near activities that may cause eyestrain and tired eyes. Its not just kids but also adults that suffer from eye fatigue due to computer use.
Dr Sao recommends the "20/20/20 rule." Every 20 minutes, look 20 feet away, for 20 seconds. It may help you get some extra computer time before eyestrain sets in.
We don't take sight for granted. Like earth, we do whats best to preserve what we have.
