What is the difference between how our eyes view the computer screen and the printed word?
Studies have long shown that the way our eyes view the computer image is very different than how they read the printed word in a book or newspaper. The images or pixels on a computer screen have poor edge definition. This can cause a repetitive focusing effort for the eye muscles, which over time generates a variety of symptoms (which is similar to any musculoskeletal injury that results from overuse).
