Who Does Dry Eye Affect?

While outdoor pollutants are common causes of dry eye, symptoms may also develop in response to indoor environmental quality. Symptoms are most likely to occur when the air's humidity drops, which commonly occurs in centrally heated or air-conditioned rooms and on airplanes. Dry eye symptoms are also relatively common among workers whose jobs involve looking at a computer screen for extended periods of time. People working at computers don't blink as often as they would if they were changing focus away from their activity more often.
