Quote from barrakidIt's funny that the CVS article on wikipedia says on the first paragraph that "These symptoms can be further aggravated by improper lighting conditions (i.e. glare [1] or bright overhead lighting) or air moving past the eyes (e.g. overhead vents, direct air from a fan).".
yeah, but even before it says any of that, it says it's temporary, which was basically the point in referring to CVS in the first place.
my dad's an eye doctor, and i actually asked him about working in front of a monitor all the time a few weeks ago. he basically denied that lighting was an issue as said above, but also said that prevailing wisdom has it that prolonged close-work (on anything, not just a monitor), is a cause of myopia.
so make sure to station your monitor 2 meters away.
