Wow, I can't believe how wrong those answers are: Fevers are not caused by being cold. Cold stimulates your immune system, kicking it into overdrive, which is why it DOES cause a runny nose for a short time, even though you're not actually getting sick. Your body is preemptively making your nose run to reduce the chances of infection. "Colds" are not because of bacteria. A cold is caused by a virus. I doubt he was asking about dry eyes. And you DEFINITELY don't use vitamin C to "moisture your eyes". Vitamin C is an antioxidant that your body needs only in trace amounts to help your mitochondria regulate their oxidization process, not to keep your eyes wet. In general, trying to get excess vitamin C is bad for you, not good for you. There is mounting evidence that trying to push antioxidants in general may shorten your lifespan. And a fever is NOT usually be accompanied by pink eye or eye infection. What the hell kind of crazy answers are these? Eye pain can be caused by inflammation of optic nerve sheath, or extraocular muscles, or a number of other similar causes, some of which could be triggered by by or have a common cause with a fever.
