* Eye fatigue: The people who work several hours on the computer tend to blink less than normal, which causes an imbalance binocular and drying of the eye. These people feel less efficient both in terms of vision and intellectually. This is called eyestrain.
* Visual fatigue: This type of fatigue appears more frequently when minor visual defects are revealed by the computer work. It also appears if ametropia (myopia, hyperopia, astigmatism) and presbyopia already this is not corrected.
