Evaluation of the Time to “Natural Compensation” in Normal and Dry Eye Subject Populations During Exposure to a Controlled Adverse Environment

As the prevalence of factors related to adverse environments, visual tasking, and systemic antihistamines increase, the incidence of dry eye symptoms can be expected to escalate, and tolerance to symptoms ofdry eye may decrease.

Abstract

Approximately 1 of every 5 Americans suffers from dry eye symptomatology. 1 Since the American population constantly encounters adverse environments, visual tasking, and systemic antihistamines, of which all can cause ocular drying, the high incidence of symptoms is hardly surprising. Furthermore, as the prevalence of these factors increase, the incidence of dry eye symptoms can be expected to escalate, and tolerance to symptoms of dry eye may decrease.
