Some possible causes of dry eye are a decrease in the production of tears which is usually considered a natural process during aging and after menopause in women. Dry eye can also occur secondary to squinting which commonly occurs during computer work, reading, driving or microscope usage. Eyelid problems, medications and environment can also lead to dry eyes. A dry, hot and especially windy climate may aggravate dry eye. Cigarette smoking in an enclosed space may also cause dry eye.
