Computer Eye Strain Explained (and How to Avoid It)
Sit Up Straight

It is easy to slouch when sitting in front of a computer for extended periods of time. Be sure the computer monitor sits four to eight inches below the eyes to allow the neck to relax while reading or typing. Sit up straight to avoid neck, shoulder and back pain, which can affect vision. Invest in a sturdy chair that is comfortable and promotes good posture. A chair with a hard back can be useful for support while a softer seat might increase the urge to slouch.
