Most of these tips work

Most of these tips work in the short term, but they only alleviate the problem; they don't actually correct it. Our experience has shown that the best corrective solution to computer eyestrain, known as the PRIO System, involves a visit to an eye doctor and some corrective lenses. The basis of this system is human physiology; instead of focusing on environmental conditions, the system uses knowledge of our optical system to correct computer eyestrain. The system is based on over fifteen years of research into the workings of the human vision. In order to better understand just how this corrective solution works, we should take a little time to understand just what causes computer eyestrain.
